PREFACE The completion of the first volume of an English Journal, specially devoted to Cryptogamic Botany, enables us to congratulate our readers and ourselves upon the achievement of a task which many friends believed to be impossible. It is, nevertheless, an accom- plished fact that " Grevillea " has reached its twelfth number, and its promoters are preparing for another year's campaign. If our subscribers and supporters will but continue their aid, this also we hope to accomplish. The complaint which some have urged, that the Journal is too scientific, will, we hope, be speedily removed, not so much by any considerable alteration in the character of the Journal, as by the assiduity of its readers themselves, whereby in- creased knowledge and experience will bring to its perusal minds more receptive, because better prepared. A popular journal was never intended, but one which should become valuable — nay, in- dispensable— to students and adepts in the branches of Botany to which it is devoted. That it has hitherto been too exclusively devoted to Fungi and Lichens is scarcely the fault of the Journal, but results from the fact that these have been less studied than the higher Cryptogamia, and more was necessary to be done to keep pace with the discovery of new species, or the better illustration of old ones. Now that the additions to British Fungi, discovered since the appearance of the " Handbook of British Fungi," have been recorded, and the descriptions furnished, there will be more of our very limited space left free for Bryologists and Algalogists to r . describe their additions, and also for communications less connected with systematic than physiological Botany. It could scarcely be • expected that we should secure the co-operation of all Cryptogam is Is PREFACE. within the short period of twelve months. Many very reasonable excuses can be made for those who may not be ready at a brief notice to espouse a new cause, or support a new venture ; but we hope that when we have demonstrated to them that our Journal has become established, having entered upon its second year, these excuses will vanish. To all who have assisted us so liberally and freely in the past, our thanks are due, not forgetting those who, by subscribing their names, gave us encouragement to venture upon an undertaking which seemed to promise only great losses and no profits. Finally, we commend ourselves and our work to all British Botanists, and urge them, for the sake of so small an annual sum, not to hesitate in giving us their support. It will be an honour to them if they enable us to continue, and even to enlarge and improve a journal of this character, and prove that Britain as well as Ger- many can sustain a Cryptogamic Journal. Increased support alone will enable us to augment the number of pages, and continue coloured illustrations as hitherto. Our success has been great, and we rely upon the good fellowship of our Botanical and Micro- scopical friends to make it greater still. The best road to improve- ment will lie through an augmented list of subscribers. Ekesperiika,. C&P. % P. floccosa P.pelHta C:>P P. siibocbraceai C&P ooo 0 J*Sr-v^~>4' {* P. erocitmcta. B & C .

A MONTHLY EECOED OF CRYPTOGAMIC BOTANY, AND ITS LITEEATUEE. 0 the memory of one of the most worthy of British Cryp- l;fi \*$b togamists is dedicated this little monthly record of Cryptogamic Botany. With some diffidence it has been commenced ; but with the united support of all students in the different orders its career may be a success- ful and useful one. What it shall become depends chiefly on the amount of support it may receive. The intention of its projectors is to furnish, month by month, descriptions in English of new species discovered in the British Islands, and to record the habitats of rare or interesting forms, for which purpose com- munications are solicited ; to furnish a record of the literature ; and, as far as space permits, descriptions of Exotic specieSj especially those of the British Colonies and dependencies, and the United States of America, or wherever the English language is spoken. Although the space is limited, it is hoped that structural and physiological subjects will receive attention, and a space will be devoted to the Queries of Correspondents and announcements of desiderata and exchanges. Illustrations will depend, both in quality and quantity, upon the number of subscribers ; but it is hoped that at least one plate, sometimes coloured, will accompany each number. It can scarce be expected that such a work will at once assume the character it is desired. Some few months must be expected to elapse before all those who may be interested in Diatomacea?, Desmids, Lichens, Mosses, or multicellular Algae will find, as well as those interested in Fungi, that each of these branches are intended to be equally cared for, and illustrated. With patience on the part of subscribers, and perseverance on the part of the Editor, it is hoped that, though small and unpretending, " Grevillea " will at least be useful, and not unworthy of the name it bears. 4 NEW-YORK FUNGI.

This very interesting lichen, which until lately was supposed to be confined to the White Mountains in North America, has been con- stantly confounded with Stereocaulon condensatum, Ach. ; but is readily distinguished by the differences in the spores, those of the former being ellipsoid and simple, and those of the latter fusiform, 3-7-septate. I have myself repeatedly gathered it throughout the Snowdonian district, Nant Francon, the Glyders, Avan Mowddy, and in other parts of North Wales, where it occurs in some abundance ; but requires careful observation to de- tect it, from its close growing habit and the minuteness of its fructification. Dr. Nylander, in the appendix to his " Lichenes Lapponica3 Orientalis," mentions it as found by M. Th. Simming at Dianovagora, near Lake Onega. And in looking over some lichens in the herbarium of Mr. Horatio Piggot, of Tunbridge Wells, I detected a remarkably fine specimen with magnificently developed fructification, under the name of St. cereolinum, which he had col- lected near the Cuchullin Hills, near Sligachan, Isle of Skye, Scotland. If carefully searched for it may be, no doubt, detected in Alpine and sub-Alpine regions throughout the world. Most of English and Scotch localities given for St. condensation and cereo- linum will, on more careful research, prove referable to Pilophoron fibula. See Leight. Lich. Fl., 2nd ed., pp. 469 and 470. Morocco Lichens. Dr. Hooker, of Kew, placed in my hands for examination and determination the lichens which he collected in his expedition to Morocco and the Atlas Mountains, in May, 1871. Though few in number they are very interesting, especially from the locality from whence gathered. They are as follows : — Cladonia endiviosfolia, Fr. Tangier and Tetuan, North Morocco.

By Robert Braithwaite, M.D., F.L.S., etc. The commencement of an English Journal devoted to Cryptogamic Botany must surely engage the attention of all workers in the wide field embraced within the scheme of its operations ; and as our opening contribution to the department of Bryology, we offer the latest arrangement of mosses. The well-known merit of the author, and the high character of most of the papers brought before the Society, require no apology for presenting it to the readers of " Grevillea," many of whom might not otherwise have an opportunity of becoming acquainted with it, and we purpose, on a future occa- sion, to review it more in detail. This " Moss Picture" will be found in the " Verhandl. Zool. Botan. Gesels. in Wien," vol. xxi., p. 375 (1871). 10 BRYOLOGY. 2. 3. Das Moosbild. auctore Dr. SECT. A. SACCOMITRIA. Archidiaca?.

The appearance of a highly interesting and noteworthy commu- nication from Professor Max Reess conveying a description of certain novel experiments instituted by him on the growth of a Collema from the spores, and giving his views as to the bearing thereof as regards Nostoc,* which I have only just seen, recalls to my recollection a seemingly remarkable, though isolated example of a not uncommon minute aquatic Nostoc brought forward by me at a recent meeting of our Microscopical Club, but not publicly ex- hibited, from want of time, and since then somehow overlooked to be recorded. I will not attempt on this occasion to give any ac-. count of Reess' views, or those of Schwendener, but will reserve my observations thereon for a future communication to this Journal. *Ueber die Enstechung der Flechte Collema glaucescens, Hoffm., durch Aussaat dev sporen derselbcu auf Nostoc lichenoides, Vauch. Prof. Max Reess, in Monatsb. der K. Acad, der Wias. zu Berlin, Oct., 1871, pp. 513. ON A MINUTE NOSTOC WITH SPORES. 11 Professor Rcess' is an abstract of the views already propounded by Professor Schwendcner as regards the nature of Lichens, •who, in his turn, seems possibly to have had suggested to him the work- ing out of some such idea as he has arrived at, by the alternative conclusion put forward by Professor de Bary as one or other being a necessary outcome or result deducible from the existent know- ledge of the gelatinous Lichens (Gallertflechten) or the Col- lemacese and allies, and seemingly embracing al«> Ephebe in his generalisation, which is thus enunciated — " Either the Lichens in question are perfectly developed states of plants whose imperfectly developed forms have hitherto stood amongst the Algae as the N-ostocacea3 and Chroococcacea3 ; or the Nostocacerc and Chroococ- caceas are typical Algaa ; they assume the form of Collema, Ephebe, and so forth through certain parasitic Ascomycetes penetrating into them, spreading their mycelium into the continuously growing thallus, and frequently attached to their phycochrome containing cells."* The former of these hypotheses, as is well known, has many supporters, and, seemingly, a considerable amount — at least, in certain instances — of evidence in its favour. The latter hypo- thesis, on the other hand, has found, if fewer, even more staunch adherents, most prominent amongst whom are Schwendener and Reess, and is in fact that alluded to as being recently put forward by him, relinquishing the views supported by him in the earlier portion of his elaborate memoir on the Lichen thallus. The little Nostoc to which I have already alluded, and to which I am desirous of directing attention, is a very minute one, though the dimensions of the subglobose or elliptic fronds vary much. It is rather common in moor and certain bog pools. On account of its small size, therefore, readily capable of compression, and its pellucid character, the elegant arrangement of its tortuously twisted rather large moniliform filaments, is often nicely seen, and this causes it to be a very pretty and favourable illustrative example of its type for examination in its entirety under the higher powers of the microscope. Its minute size calls to mind Nostoc minimum (Currey),f but in it the cells are described as quadrate with a sinus at each side, lending a crenate outline to the filaments, and the heterocysts are large, whilst here the cells are orbicular or for a time slightly flattened at the junctions, and the heterocysts are but slightly wider, though longer than the ordinary cells. This plant is probably identical with Nostoc jjaludosum (Kiitz.), though as re- gards anything to be deduced from the heterocysts Kiitzing is silent. But the interesting point connected with it is a single example of it having presented indubitable " spores," and precisely similar nature to those in Sphrcrozyga, &c, but with the peculiarity of * Morphologie u. phys d.

(1st ser.), page 216. 12 ON A MINUTE NOSTOC WITH SPORES. these being always placed singly between two heterocysts. The pairs of heterocysts with the intervening spore occurred at just about the same intervals as in ordinary examples occur the isolated heterocysts; the spores large, broadly elliptic, about one-third longer than broad ; their diameter more than twice the diameter of the heterocysts, about thrice the diameter of the ordinary cells ; the " bright points " of the heterocysts not very conspicuous. I would explicitly deprecate any supposition that the observation was founded on any mere isolated filament, met with in the same material as the rest of the ordinary examples of this Nostoc around, and assumed by me to have emanated from some of them, and, therefore, possibly that of some other genus. The filaments were not isolated, but contorted about in quite the ordinary way, were still involved in the parent matrix, which was bounded by the distinct pellicle, or " periderm," generically charac- teristic, and in all respects, save the remarkable speciality described, this example was absolutely the same as the others in the same gathering ; in fact, the little Nostoc was intact. It might be said, possibly, this little plant was rather a Monormia, but the definite periderm to the rounded fronds places a bar to the assumption, and I do not think any observer would see it and pronounce it other than a Nostoc. In making a drawing for illustration it is of course unnecessary to present more than one spore, with its adjacent heterocysts and a few cells of the filament. To give the total frond and its long, tortuously looped and curved filaments, with their numerous spores and heterocysts, and to convey an idea of the matrix, with the bounding periderm, would have been an unnecessary labour and expense, and to carry it out on the scale of some 400 diameters would have occupied a very considerable space. The interest which attaches to this example of a spore-bearing Nostoc will be more apparent after reading my observations on Reess' views, which will follow, and which are necessarily excluded here on account of the limited space at my disposal. Australian Fungi. — Mycologists will be glad to learn that the last number of " The Journal of the Linnean Society" (No. 67, for May), contains a valuable communication by the Rev. M. J. Berkeley, on Australian Fungi. In addition, we may observe that the same number contains a communication by Dr. Dickie on the Marine Algee of the Island of Saint Helena, and two communications by Dr. S. (J. Lindberg on Mesotus (Mitten) and Zoopsis (Hook and Thorn.). 13 CHICAGO HYDRANT WATER. From a communication on this subject, by H. H. Babcock, in the second number of " The Lens " (Chicago, U. S.), we extract the following observations : — " Some species of diatoms, as Tabellaria fenestrate and Fragil- aria Crotonensis, produced in abundance all along the shore of the Lake, are always to be found in the hydrant water. Surirella splendida, Cymatopleura solea, Stephanodiscus Niagara, Asterionella formosa, and a Cymbella, which one may sometimes observe in a shore gathering, are occasionally present. A Melosira, identical with that found in small streams flowing into the lake at Glencoc, is often seen ; Pleurosigma attenuatum more rarely ; while Pleuro- sigma Spencerii, Amphiprora ornata, and a Rhizosolenia are the rarest species. " In a word, we receive through the hydrants many of the free, unattached forms, known to be produced along the lake shore, and on streams entering the lake to the north of the city, as well as a few species whose origin has not been determined ; while the stipitate or otherwise attached forms, as Gomphonema and Synedra, though growing in abundance in the vicinity, are seldom repre- sented. "I am led to believe that the streams of Northern Illinois, Wis- consin, and even Northern Michigan, are the source whence we obtain some of the diatoms most rarely observed in the hydrant water, and that these forms, coming within the influence of the southerly current of the lake, are brought as far as the crib which stands within the current, but near its easterly edge. In a gather- ing made at the mouth of the Carp river, a stream of Northern Michigan, nearly opposite the island of Mackinac, I have found an abundance of Pleurosigma attenuatum and Spencerii, Surirella splen- dida, and Amphiprora ornata. It is probable that other streams in the vicinity, and to the southward of that named, produce the same species, which, specifically light, are borne by the current as far as Chicago, and that the reversal of the course of Chicago river has caused the lake current opj^osite the city to swerve slightly towards the west, and admitted to the crib the pure water from the deeper, undisturbed part of the lake. " Whether the river or lake current, or, as I am inclined to believe. both combined, are the source of these organisms, there seems to be no doubt that so long as there is kept up in the river a mode- rately rapid current from the lake, the city will be provided with water more nearly approaching in purity that at Mackinac and Lake Superior, which is remarkable for its transparency." 14 RHIZOSOLENIA ERIENSIS. Rhizosolenia Eriensis. H. L. Smth.— Frustules small, com- pressed, somewhat flattened ; not rigidly siliceous, 6-12 times as long as broad ; length -003--006 in. Annuli on the dry frustules conspicuous, apparently interrupted in the middle, and alternate ; obscure in fluid or balsam. Frustules finely striated. Bristles nearly as long as the frustules, and, with the calyptra, excentric, lying nearly in a line with one margin of the frustule when the flat side is in view. Chicago (U.S.) water-supply; very abundant at certain seasons, and very rare at others. Originally noted in Lake Erie, at Cleve- land, O. — S. A. Briggs in " the Lens,"" for Jan., 1872. NEW AMERICAN POLYSIPHONIA. The following species is described as new, by C. H. Peck, in his Report for 1869, just issued. Folysiphonia subcontoita. Peck. — Tufts rigid, 2-3 in. high, loosely entangled, dark red ; filaments slender, naked below, alter- nately, and sub-distantly branched above ; branches short, subequal, naked at the base, much branched above, and expanded into a rigid subsquarrose bushy tuft of ramuli, which are subfusiform and more or less curved or contorted ; tubes four, surrounding a small cen- tral one ; articulations of the leading filaments 6-10 times, of the branches 2-4 times their breadth, those of the ramuli shorter than broad ; tetraspores in the swollen part of the ramuli. — Report, p. 51 . Rocks near low water mark. Long Island Sound, at Greenport and Orient. July. The filaments are about as thick as hogs' bristles, nearly equal in thickness throughout, constituting a leading stem, with its articulations distinct and very long towards the base, and giving out its branches, which are four or five lines long at intervals of 3-4 lines. The plant becomes blackish in drying, and does not adhere closely to paper. In size, consistency, and coloration this species resembles P. fastigia ta ; but in ramification, number of tubes, length of articulations, etc., it is far removed from that species. Amexican Desmids. — The seven new species of Desmids described by Dr. Wood in the " Proceedings of the Academy of Natural Sciences," at Philadelphia, are named by him, — Euastrum multih- batum. Euastrum ornatum, Arthrodesmus quadridens, Staurastrum minutum, Staurastrum Lewisii, Cosmarium suborbiculare and Pleuro- tcenium breve. Descriptions in Latin, with measurements, will be found in Hedwigia for 1872, No. 1, p. 3. 15 New Hepatic ae.— The following new species of North American Hepaticae are described by C. F. A. Austin in the Bulletin of the Torrey Botanical Club, for March, 1872: — Sarcoscyphus Bolancleri, Sarcoscyphus BceckiijScapania Oakesii, Junqermannia crenuliformis, Jungermannia Wattiana^ Jungermannia Sullivantia>, Jungermannia Gillmani, S.phagnoecetis 3facounii, Madotlieca Bolanderi, Madotheca Sullivantii, Lejennia Sullivantice, Frullania Wrightii, Frullania Sullivantia?, Frullania pendula, and Fimbriaria violacea. We regret to see that the "complimentary fever" is raging so strong across the Atlantic ; here are eighteen new species, of which no less than twelve have " complimentary" names, the same individual heing four times immortalized. Dimorphic Diatoms.— Last October (1871) I collected in the salt water at Helle Gat, North end of Norfolk Island, a Melosira, which was in part M. nummuloides and part 31. Borrerii, as Smith defines and figures. I have for some time expected that these two forms were only one species. In September (1871) I collected in a small stream on Union Hill, N. J., Gomphonema constrictum, capitatum, acuminatum, and cristatum, all on the same stalk. Also sporangia (?) of 3Ielosira varians, different from any I have ever seen before, they are like little " dumbbells," consisting of two globes united by a short isthmus. Hydrodictyon utriculatum is very common around New York. — Arthur 31. Edwards, M.D., Newark, N.J. Alphonse de Brebisson.-The death of this veteran cryptoga- mist took place at Falaise on the 26th April last, at the advanced age of 74 years. It is with regret that we shall be deprived of his promised assistance, that we make this announcement. Another of the contemporaries of Smith, Greville, and Walker Arnott has finished his course. A large and valuable collection of some thou- sands of slides of Diatomaceee, the accumulation of an active life, is to be disposed of by his son, M. Rene de Brebisson. It is to be hoped that some Microscopical Society, or public institution like the British Museum, will secure the collection in its entirety. Dr. M. A. Curtis.— The death of the Rev. Dr. M. A. Curtis, of Hillsborough, North Carolina, U.S., leaves a blank in the short list of North American mycologists which we fear will not soon be so efficiently filled up. Edible Fungi.— The following species are enumerated by C. H. Peck for the State of New York: — Agaricus ca!sarius, Scop. ; Cor- tinarius cinnamomeus, Fr. ; Cortinarius castcuieus, Fr. ; Lactarhis deliciosus, Fr. ; Lactarhis subdulcis, Fr. ; Cantharelhis cibarhts, Fr. ; Lycoperdon cadatum, Fr. ; Lycoperdon gigaitteum, Batsch. ; Jlolvtus luteu8,JJmu..\ Boletus J/avidvs, Fr. ; Boletus collinitus, Fr. ; Boletus subtomentosus, Linn. ; Boletus edulis, Bull. ; Hydnum inl- and Helvetia Infula, Schorl*. 16 CRYPTOGAMIC LITERATURE.

As promised in the preceding number of this journal, I purpose setting forth, as briefly as possible, the views of Schwendener and Reess (page 11) on Collema, &c. Relinquishing the opinions sup- ported by him in the earlier portions of his elaborate memoir on the Lichen-thallus,* Schwendener, before he concludes, propounds the doctrine that not only are the " Lichens" in question (the Colle- macea3, alluded to by de Bary) no " Lichens," but that the whole class, without excej)tion, fall under the same category ; that is to say, that each is to be regarded as some one or other Algal-type which has become, as it were, the home or residence of a parasitic growth — the combination of the two being, in point of fact, the so-called Lichen. His views on the question the author has given more at large, in relation to various types, in a subsequent memoir, j" These he states generally thus : — " As the result of my researches all these growths [Lichens] are not simple plants, not individuals in the ordinary sense of the word ; they are rather colonies, which consist of hundreds and thousands of individuals, of which, how- ever, one alone plays the master, whilst the rest, in perpetual cap- tivity, prepare the nutriment for themselves and their master. This master is a fungus of the class of Ascomycetes, a parasite which is accustomed to live upon others' work : its slaves are green alga3, which it has sought out, or indeed caught hold of, and com- pelled into its service. It surrounds them, as a spider its prey, with a fibrous net of narrow meshes, which is gradually converted into an impenetrable covering ; but, whilst the spider sucks its prey and leaves it lying dead, the fungus incites the algas found in its net to more rapid activity — nay, to more vigorous increase. ... If this mode of illustration be permissible, this fungus forms a remark- able contrast not only to the predatory and murderous spider, but, in quite an analogous way, to the vine and potato-fungus, as well as all other fungi which vegetate in living organisms, and destroy their host-plant, or host-animal, in the unequal struggle.''^ Such, " popularly" expressed, is Schwendener's view as to " Lichens" at large, which he now holds and supports. This quotation, I would venture to suggest, would seem sufficiently to convey its own refu- tation of the hypothesis, inasmuch as this assumed parasitic fungus does not destroy or live upon its assumed algal-host. If the ''parasite" cannot be a "fungus" it must be something else — that something else no more nor less than the veritable " lichen," though it may be, indeed, but in part represented; though, of # Dr. S. Schwendener — " UntersiichungenueberdenFlechten-thallus," in Prof. Niigeli's " Beitriige zur wissensch. Botanik," Hft. 4, p. 195 (1868). f Dr. S. Schwendener — "Die Algentypen der Flechteugonidien," Basel, 1869. X Schwendener — " Die Algentypen," etc., p. 3. OBSERVATIONS ON COLLKMA. 23 course, on all hands it is agreed that Lichens and Fungi, save the gonidia, have between them no absolute line of demarcation. Seemingly at first more impressed with the applicability of the theory to the Collemacese, though he no doubt afterwards accepts its complete tenabilit j as regards the whole class of the " Lichens," Reess conceived the idea of " sowing" the spores of Collema upon the substance of Nostoc, and a description of the experiment and its results forms the subject of his memoir previously alluded to.* He states, indeed, that the spores of Collema ran be readily enough made to germinate upon any moist substratum, such as a glass-plate, stones, and so on, and will slowly produce even a branched and sparingly jointed growth, but this goes on only so long as the reserve- stuff is supplied by the spore, but when this is exhausted the liypha- mass thus produced, though it may survive even weeks, will then slowly die off. But when he brings a spore or the young hypha upon the Nostoc, it at once becomes further developed, sending more or less copiously through its surface many branches, and penetrat- ing within. Soon, however, they cease to increase in length, be- come swollen at the points and at other places, and become attached by these swellings upon the Nostoc. Thereupon thinner processes become sent further into the gelatinous mass of the Nostoc, from the swellings ; these become branched, and, tortuously surrounding the chains of gonidia, form, in fact, the " Collema-mycelium," and the complete transformation or conversion of the " Nostoc" into the Collema is brought about by the hypha producing a peripheral stratum of fibres, from which break forth, through the " Nostoc - jelly," the first root hairs. Such an artificially -produced " Collema" the author had not been able to rear up as far as the production of fructification (apothecia), but he doubts not the tenability of the assumption that every Collema in free nature is a " Nostoc" thus made the nidus for the development of the spores, evolved of course from a preceding " Nostoc " so naturally inoculated (as one might say), i.e., in other words, a preceding compound organisation which is known as " Collema." Such is, as brief as possible, the result of Reess's experiences, and the views he holds ; it would far exceed the limits available in these pages to go more closely into the arguments and statements of Reess and Schwendener — those of the latter applied to the Lichens at large, not the Collemaceaj only — but it may not be wholly without use to have directed attention to their remarkable memoirs. Basing his opinion, as it would seem, at least mainly, upon the result of the experiments of Professor Reess alluded to, Professor Cohnf would exclude the Collemacere from the Lichens, which ^without these), as a Class, he would retain, remarking that "he * Prof. Eeess— "Ueber die Entstehung der Flechte Collema glaucescens, Hoffm. durch Aussaat der Sporen derselben auf Nostoc lichenoides, Vauch." in " Monatsb. der k. Akad. der Wissensch. zu Berlin," Oct. 1871, p. 523. f Prof. Dr. F. Cohn — " Conspectus Familiarum cryptogam; i rum secundum method um naturaltm dispositarum," in " Hedwigia," No. 2, 1872, p. 17. 24 • OBSERVATIONS ON COLLEMA. knows no Alga? which could be transformed by the influence of a fungus into Usnea, Cladonia, Cetraria, etc., but that it appears to him that the parasitism has been rendered by de Bary and Reess extremely probable for the ' Collemacea}.' " Schwendener himself, in his later memoir,* figures certain Nostoc specimens whose gelatinous matrix is seen to be penetrated by what he denominates fungal threads (Pilsfaser), and these he points to as evidence of the truth of his view ; that is, that they become the hypha, and that the phenomena of growth thereby induced absolutely convert the " Nostoc " into " Collema ;" and he firmly holds his figures prove the case. Now, Reess, referring to these very figures, conceives the fungal threads depicted must be strictly those of a (destructive) fungus — a mould, in point of fact ; he thinks, indeed, they may be anything whatever, but one thing clearly he avers, be they what they may, they are by no means a Collema-hypha, founding his opinion, of course, upon the know- ledge gained from his recently conducted experiments. So that whatever may be the opinion of other observers as to the result of the researches of Reess, at least the examples adduced by Schwendener relating to Collema, it would appear, must be held as inconclusive. It may, perhaps, be not inoj)portune to observe that, as must be well known, the gelatinous masses of those Alga3 which grow on wet rocks and-such situations, be they Palmellaceous or Chroococcaceous, i are prone to be more or less permeated by " mycelioid " threads, and even some such as would fairly well accord with those Reess depicts for Collema, though not so copiously branched, may not be unusual. Some of these threads are, at least occasionally, those of indubitable (devastating) fungi, which, when they " attack " certain cells, destroy them ; other threads, doubtless quite distinct, can apparently live independently and innocuously, though probably drawing nutriment from the common mucous matrix. What a monstrous and abnormal " Lichen-th alius " thus not unfrequently comes to view — a variable " hypha " interruptedly running hither and thither, and accompanied by " gonidia " of very heterogeneous character ! The plant named by Kutziiig, Trichodictyon rupestre, which can hardly be doubted to be the same as Cylindrocystis crassa, de Bary, is frequently (though not always) accompanied by a number of fine filaments (which seem, however, to be inarticulate), twisted in and out through the gelatinous mass made by the alga, but so running as to leave rounded spaces between containing the groups of the Cylindrocystis-cells ; they seem, in fact, to urge their way between the more dense mucous envelopes formed round the groups of dividing cells, simply because they find the intervals, being softer, more readily permeable. These filaments, whatever their nature really may be, cannot be doubted I should think to be foreign, though they were actually introduced into the generic * " Die Algeiitypen," etc., pp. 28, 29, t. II., ff. 13-15. OBSERVATIONS ON COLLBMA. 25 characters by Kiitzing, being considered by liim as somehow a por- tion of the structure of the alga, which, indeed, itself reproduces by conjugation, and is, no doubt, in i'act, a dcsmid. Bchwendenei claims as the foundation or basis for the production of " Collemacese " only such nostochaceous plants as live in moist or wet habitats — the entirely aquatic forms (Trichornras, SphaBrozyga, Cylindrospermum, Dolichospermum), he considers, being inac sible under water, are protected from the attack of the parasite, and thus " cannot enter into the ' gonidia question.' " The fact that these latter form independent "spore-cells" (reproducing the plant), he would seem, so far as we can judge, to hold as having no material, if any, bearing on the question, for he dwells only on their being submerged as giving them an immunity. " But in any case," he says, afterwards, further on, as regards the question, " whether certain species of Cylindrospermum pass into the 'gonidia state' [that is, become the basis of Collemacea1] remains for so long doubtful, till the transition, here alone decisive, be observed. In the Collema-thallus itself a decision is of course no longer possible, since the spores characteristic of Cylindrospermum ap- parently just as little come to development in the gonidial state, as do the ' manubria' of the Rivularieas." (This last allusion has a bearing on Lichina, &c, which the author thinks have plants appertaining to Rivulariea3 for their basis, but without manubria.) I would venture to suggest were such Algre as these truly seized upon by this completely innocuous parasite — nay, which, if tin' hypothesis be true, rather tends to favour the growth and vigour of the " gonidia" — we should hardly expect that, on the other hand, the innate or inherited tendency to produce "spores" would at the same time become wholly extinguished. It would, I should venture to suppose, seem probable, even admitting the views of Schwendener and Reess as regards Nostoc, that Cylindrospermum is not likely to have anything to say to the "gonidia question."' But the isolated observation, for the first time recorded in the pre- ceding brief communication,* would seem to show that Nostoc, too, may form spores, though it be, indeed, so very exceptionally, and so extremely rarely. The main object, then, of the present communication is to offer the following three suggestions which occur to me : — 1. To suggest the possibility that, if we may conceive Dolicho- spermum, &c, excluded from the "gonidia question" as forming special fruit (that is, " spores "), so might we regard Nostoc as ex- cluded, though its formation of spores be so extremely rare. Seemingly, indeed, the formation of spores by an algal species, supposed to become occasionally lichenized, is not a reason against the hypothesis as viewed by Schwendener — he only assumes that such an example of the alga surrenders, or leaves in abeyance, its tendency to the production of spores. * " GreviPfca," Xo. 1. July, 1872, p. 10. 26 OBSERVATIONS ON COLLEMA. 2. To suggest that there are veritable lichens which live sub- merged, and produce their apothecia. I presume, however, it might be replied that such may have received their inoculation by the parasite during some season of drought, when the alga lay "high and dry." 3. To suggest the possibility that the spores of Collema, if " sown " on some other gelatinous substratum, besides that of Nostoc — say, for instance, a Palmella or Mesotaenium — might equally well germinate, penetrate therein, and develope a hypha. There seems, I venture to think, no a priori reason against this supposition — inside the Nostoc, the " reserve-stuff " of the spore being exhausted, and the chains of Nostoc filaments admittedly intact, the only next immediate source of nutriment for the growing hypha would, I imagine, in the experiment of Reess, appear to have been the " Nostoc-jelly." Now a " Palinella-jelly," or a " Mesotaenium -jelly " (both aerial, that is, not under water), would seem in themselves to be possibly just as likely to afford the requisite pabulum for the germinating and growing Collema-spore. If this conjecture should be borne out, which I would indeed put with all diffidence, what would be the result of Reess's experiments, or, rather, what proven thereby ? Such a combination (if capable) with a Palmella or a Mesotaenium would not be " Collema," because it would not have " nostocha- ceous " gonidia, nor the characteristic periderm. If, indeed, we might for a moment assume that which direct experiment alone could prove, and a germination of spores and penetration of the hypha of a Collema with a Mesotaenium effected, such a " lichen- thallus " would be, I apprehend, unprecedented — a hypha like other lichen-hyphae, no doubt (but known to be that of a Collema), with large elliptical or cylindrical "gonidia" containing a central " chlorophyll-plate," and which would probably (in free nature at least) go on and produce zygospores I I trust that the readers of these and my foregoing remarks will understand that I put them forward but with great diffidence ; it was the occurrence of my little spore-bearing Nostoc, which sug- gested to me to venture to do so. Isolated, indeed, as was that example, still no matter from what aspect viewed, even though it be urged that we should look upon it as " abnormal " on account of its rarity, it cannot, I apprehend, but be regarded under any circumstances as to a certain extent suggestive and as possessing a considerable amount of significance.

We fear this interesting little moss can hardly be regarded as indigenous, for the spores have most probably been mixed with soil attached to some exotic, and thus accidentally scattered on the sandstone wall, where it was found. So much do the leaves re- semble those of Splachnacea3 in ar eolation, that at first I was in- clined to follow C. Miiller and Hampein referring it to that family ; but on the other hand the equally high authorities Mitten and Lindberg place it in Trichostoniaceae, and after careful considera- tion I am satisfied that in the structure of the peristome, the calyptra like that of Tortula, and the place of growth it entirely accords with that family. The type of the genus is S. obtusum, C. Mill. Bridel ( Weissia ob- tusa, Sp. Musc.,i., p. 118, 180G; Didymodon? splachnifolius^ Hook. Muse. Exot., t. 126, 1820; Dissodon rotundifolius, C.

Miiller in the paper quoted, and with the Cuba plant the Irish specimens, kindly sent by Dr. Moore, agree in everything but size, and though Miiller describes the leaf as " margine integerrimo " in both, it is distinctly crenulate. The other species of the genus are — 3. S.flaccidum (Weissia flaccida, Harvey, Hook. Ic. PI., t. 18, f. 3), from Nepal. 4. S. Wullschldgelii, C. M., from Surinam. 5. S. Bernoullii, C.

Another species is also referred to with papillose leaves, from Tranquebar. — Journal of Botany, for July, 1872, p. 193. Observations on the above Moss. By Prof. Lindberg. The characters of the plant before us show that it cannot be an Entosthodon (i.e., Funaria), but that it must belong to a different tribe of mosses, and if we pass before us all the European species, we do not find one allied to it, and must therefore extend our view to exotic forms. In the tropical parts of America and Asia grow a few minute tufted mosses, which have lately been considered to form a proper genus [Tapeinodon or Splachnobryuni), the type of which is the old Didymodon (?) splachnifolius, Hooker. The specimens named Tapeinodon splachnifolius, from Tarapoto (No. 209, b. coll., R. Spruce), seem to be a proper robust form or species distinguished by its size and larger flaccid leaves. Another species is Weissia flaccida, Harvey, very distinct by its erect narrow leaves, reflexed at apex, which is obtuse as in all other forms of the genus. As to its systematic position, it has not a natural place among Splachnacese, or Funariaceas, for the following characters militate against it : — The habitat on rocks or naked barren soil ; the habit resembling that of certain Trichostomea?, thus the plant from Tara- poto is very like some states of Tr. tophaceum ; the usually dull green or light dirty brown colour of the leaves, which are small and nearly all of one size, easily softened in water, and with cells for the most part distinctly incrassated, and the uppermost much smaller than the rest ; the dioicous inflorescence (no dioicous form has yet been found among Funariacea?) ; the open indistinct andrcecium, which wants all trace of paraphyses ; the very narrow pungent teeth of the peristome, with numerous trabeculas on the inside and papil- lose on both surfaces, and, indeed, not much unlike that of Eucladium verticillatum ; and, lastly, the very narrow calyptra, and seta twisted just as in Trich. rubellum. Judging from all these characters, of great importance in a natural arrangement, I must place the genus in Trichostomea?, where we find some forms, e.g., Pottia vernicosa (Bryol. Javan. t. 51), having leaves of nearly the same structure. A NEW MOSS FROM IRELAND. 29 The oldest denomination of the genus is rather difficult to deter- mine. The Bpecies have been called I • v different authors Didymodon, Dt8Sodon, Pottia, Syrrhopodon, and Weissia ; but only Dr. C. Mallei and Mr. Mitten have given them proper generic denomina- tions. The former called tlic genus at firsl Amblyphyllum among the synonyms under his Dissodou rotundifolius (Synop. Muse. I., p. 1 10), but without any diagnosis ; later (in Verh. X. B.3 I Wien, 1869, p. 503) Splachnobryum. Mr. Mitten also has named it, but without any generic description, Tapeinodoni in Spruce, Cat. Muse. Amaz. And., p. 1 (1867), and in his Muse Austr. Amer., p. 141 (18G9), Weissia, Sect. 8, Tapetnodon. Which name musi we adopt according to the law of prioiity ? 1 think Amblyphyllum ; but we must not forget that in Midler's Syn. Muse. I., p. 286, we again find the same name applied to a section of Bryum* But this section, formed of B. calophyllum and cyclopliyllinii, is very unnatural, and can never be considered as a genus, distinct from the other species of the vast genus Bryum. I cannot, therefore, see any objection to using the denomination Amblyphyllum for this very natural and interesting genus of Trichostomece. A Grimmia new to Britain. Mr. Bagnall, of Birmingham, detected, in June last, a species of Grimmia he could not determine, which I at once recognised as G. crinita, Brid., a species closely allied to G. anodon, and occurring in Southern Europe, on the plaster of walls. He found it occupy- ing a precisely similar locality on the wall of a bridge over the canal a few miles from Warwick, and its characters are as follows : — Grimmia crinita, Bridel, Sp. Muse., part 1, p. 95 (180G). Monoicous, in low diffuse flat tufts, silky on the surface, with long white hairs, which form a pencil-like tip to the branches. Stem simple, or but slightly divided. Leaves imbricated, erecto- appressed, lowest lanceolate, muticous, upper obovate, oblong channelled, with a broadly diaphanous apex continued into a hair as long as the lamina, which in the pericheetial leaves extends far above the capsule ; nerve vanishing below apex ; margin erect or plane; cells at base elongated, diaphanous, above finely chloroph)l- lose, oblong or rounded, large, incrassate. Capsule on a weak sigmoid pedicel, subcernuous, subventricose ovate, lightly striate brown, furrowed when dry ; operculum convex, with an obtuse conical point ; annulus broad, compound ; calyptra dimidiate, bilobed ; teeth of peristome red, erect, bi-trifid to the middle. R.B. * As the system of vegetation in mosses must be regarded as of much greater importance than that of fructification, in the natural limitations of the higher divisions, I am convinced that Lcptobryum pyriforme holds a very artificial place among the true Bryccs ; and I propose to transfer it to Ditrit chacea), on account of its habit and mode of growth, the form and structure of the .uid bracts, the synoicous inflorescence, and the glossy leptodermoufl theca. The habit and leaf structure are nearly the same as in 1>. pallidum, and this very natural genus thus holds in Ditrichacece a place analogous to Lamprophyllum (WeberaJ, among teryece, and, indeed, there exists between these two genera (Leptobryum and LampropTvylkmi), analogy, but no affinity at all. 30 NOVARA DIATOMS.

Leighton, B.A., F.L.S., F.B.S.Ed. The Lichens of Bettws-y-Coed, North Wales. A fortnight's sojourn, in the month of June, 1872, amongst the magnificent and romantic rocks and woods surrounding Bettws-y- Coed, in the valley of the Conway, is, in itself, a thing long to be treasured in the memory ; but to the lichenist, who finds those rocks and woods abounding with rare and beautiful lichens, it is 11 a beauty and a joy for ever." As a general rule, mere lists of localities of plants are scarcely advisable, but the knowledge of lichens, and of their distribution over the British Isles, is as yet so incomplete and imperfect, that a devi- ation from this rule may be possibly pardoned. Assuming this, I proceed to enumerate the lichens which I observed and collected in this circumscribed nook of lovely scenery. The Collemacei, curiously enough in so damp a locality, seem to be comparatively rare, Collema fiaccidum, Ach., barren as usual, but abundant ; a few plants of Collema nigrescens, L., sterile ; Lep- togium lacerum, (Ach.), sterile ; and a single specimen of the rare Leptogium Burgessii, (Lightf.) in fine fruit, being all their repre- sentatives. Caliciumhyperellum, Ach., was the only representative of the Caliciei, though I think I also observed the barren thallus of Coniocybe furfuracea, Ach. Cladonia squamosa, Hffm., and Cladonia digitata, Hffm., var. macilenta, Hffm., f. carcata, Ach., occurred in surpassing beauty and luxuriance on the trunks of trees, at the Conway Falls, together with well-fruited Usnea bar- bata f. hirta, Fr. ; and Cladonia cervicomis, Schjer., in equal luxu- riance on the rocks above the Gwydir woods. Stereocaulon nanum, Ach., very fine, and abundant, but sterile as usual. Ramalinafari- nacea, (L.), large and abundant but sterile, and Ramalina fastigiata, Fr., finely fruited. A single specimen in jruit !! of Cetraria aculeata, Fr., was gathered on the rocks. Nephromiinn lusitanicum, Schjer., was most abundant, in fine fructification in all the woods, especially in the Gwydir woods, where the trees were clothed with it. Peltigera horizontalis, (L.), and P. scutata, (Dicks.), were not unfrequcnt, the latter sterile. Stictina limbata, (Sm.), Stictina fuli- ginosa, (Dicks.), and Stictina scrobiculata, (Scop.), and Sticta pul- monacea, Ach., very fine and luxuriant, but always sterile, were abundant, and Ricasolia hetevirens, (Lightf.), in fine fructification, but partial. Of Parmelia, the following were noticed : caperata, (L.), olivacea, (L.), physodes, (L.), and its variety labrosa, Ach., clothing the young trees, one specimen in fruit, perlata, (L.),fuligi- nosa, DuB.,corticole in fruit, conspersa, Ehrh., and its form Mou- geotii, Sch.er., sa.ratilis, (L.), corticole form in good fruit, and its variety omphalodes, (L.), also in fruit, Borreri^ f. olivacea, Lbight., and ttliavca, (Am.). Umbilicaria pvlyphex ; hypothecium brownish-black ; hymeneal gelatine intensely bluish or dark-blue with iodine. On calcareous stones amongst detritus, on the summit of Ben-y-gloe (Crombie, August, 1871). 7. Lecidea atro-badia. Nyl.— Thallus dull-brown or greyish- brown, thinnish, areolato-diffract, hypothallus black, radiating at the circumference (medulla I — ) ; apothecia black, somewhat con- vex, immarginate, concolorous within ; spores 8 na3, brown or black- ish, oblong, 1 -septate, 0,021-30 mm. long, 0,010-14 mm. thick ; epithecium violet-brown, with K faintly purple ; paraphyses not very distinct; hypothecium brown; hymeneal gelatine intensely bluish with iodine. On quartzose rocks on the summit of Ben-y- gloe (Crombie, August, 1871). Allied to L. badio-atra. 8. Verrucaria submicans. Nyl.— Not unlike V. punctiformis, var. tremula, but with longer spores, 0,020-26 mm. long, 0,006 mm. broad. It is allied also to V. elongatula, but this species has the spores more fusiform. On the bark of hollies in the New Forest (April, 1868, Crombie). 9. Verrucaria analeptella. Nyl.~- Similar to V. epidermidis, f. analepta, but with the paraphyses soft, distinct, though but slightly evolute. From V. fallax it is distinguished by the smaller apo- thecia, and different thecae and spermatia. On the bark of trees in Ireland, frequent (Carroll). It appears in Anzi L. min. r. No. 395, s. n. Sagedia cenea. 10. Verrucaria spilobola. Nyl.— Thallus black, thin, evanescent ; apothecia black, small, somewhat prominent, crowded or subma- cuiari-aggregated, the perithecium entire, black; spores 8 na?, colourless, oviform or oblongo-oviform, slightly 1-septate, 0,015-2 mm. long, 0,007-8 mm. thick ; paraphyses none ; hymeneal gela- tine not tinged with iodine. On calcareous stones on Craig Tul- loch (August, 1871, Crombie). This species has the green gonidia often 4 connate, and belongs to the section of V. mesobola. Synopsis of New York Uncinula ; by Charles H. Peck, con- tains the following species: — Uncinula circinata, C. & P., on maple leaves ; Uncinula adunca, Lev., on leaves of willow and poplar ; Uncinula macrospora, Peck., on elm leaves (scarcely ten- able) ; Uncinula parvula, C. & P., on leaves of Celtis ; Uncinula jiexuosa, Peck., on horse-chestnut leaves ; Uncinida Clintonii, Peck., on leaves of Basswood, and Uncinula ampelopsidis,Veck., on leaves of woodbine. 63 THE NEW CONSPECTUS OF THE FAMILIES AND GENERA OF DlATOMACEiE. By Professor H. L. Smith, of Geneva College, New York. The July part of the " Lens" contains the Index to the above Conspectus. It will be found that the Professor has applied the pruning knife most unsparingly, doubtless to the great disgust of the " species mongers." Some of the genera might, Ave think, have been retained with advantage ; for example, the Campylo- disci, which has been relegated to the Surirellai. This genus has two unvarying characteristics, viz., the circular form of the valves, and the median space of the two valves of the frustule are always at right angles to each other; consequently the valve must be truly circular. Professor W. Smith, the author of the Synopsis, has erred in placing Campylo discus spiralis in that genus. Kut- zing was right in making it a species of Surirella (S. spiralis). The union of the genera Triceratium and Amphitetras with Bid- dulphia we think will not be generally accepted ; to do so necessitates the enlargement of the generic characters of the last to too great an extent. The number of species will also be inconveniently large.* The genus Triceratium might, we think, be united to Amphite- tras without much alteration of the generic character. The author is, no doubt, right in abolishing the conditions of stipitate, tubular, &c, as being of no value. He remarks, " The conditions frondose, stipitate, filamentous, tubular, &c. I have not considered sufficient to warrant the formation of new genera. A long study of living forms has convinced me that these characters are fleeting — not to be relied on. " Among the Schizonemea?, e. g., the fronds are quite variable which enclose the same siliceous frustules ; and the fronds them- selves vary with the habitat. The tubes of Colletonema and En- cyonema disappear in quiet waters, and the frustules become embedded in amorphous jelly, or quite free." The number of genera dealt with in the Conspectus, and which the Professor says "includes, as far as I am aware, either as ad- missible or among the synonyms, the name of every genus hitherto constituted," is 299; the number deleted is 189, thus abolishing nearly two-thirds ! ! ! We find on comparing the Conspectus with the Synopsis of British Diatoinaceae 23 out of the 59 genera described therein deleted. The following list shews the genera retained, but in order to * The author will no doubt complete the Synopsis by publishing a Conspectus of the Species of Diatomaceas. 64 • DIATOMACE.E. embrace all the species in the Synopsis, nine genera not included in that work are added : — 1.

Some years since I became interested in the statements of Dr. J. H. Salisbury, of Cleveland, Ohio, in reference to the germs of ague. Dr. Salisbury* believes to have discovered the malarial essence in the cells of certain Palmelloid plants. Desiring to in- vestigate the subject, I sought for the plants described by him, in the ague bottom of the Mississippi river, opposite Keokuk, Iowa, lat. 10° 25'. Not being provided with a suitable microscope, I was unable to discover the microscopic algse described by the doctor. I was pleased, however, to find the fungi, samples of which I send you. Generally it answers Salisbury's description. It does not correspond in these important particulars : Salis- bury's plants are so minute that it requires a powerful lens to render them visible. A single specimen of plant may be discovered as you stand. Salisbury's plants were not less. These have roots "S" or t3^" °f an mcn ^n length. They grow on the flat moist allu- vium of the slough and river margins and their drying beds ; in the vicinity of such localities they may be found on ordinary soil in damp places, even at some elevation. The specimens sent you are green ; I have observed them slate- coloured, pink, and black. They vary in size from a mere point to ■£% of an inch in diameter. When in natural state they are globular in shape and of a fresh colour, when covered with water they swell and present a gelati- nous appearance. They discharge their spores when ripe by slit- ting open at the top and a falling in, collapsing of the upper cir- cumference ; so that a discharged plant appears cup-shaped, and to the naked eye it seems to have lost the upper half of its circum- ference. So far as I have been able to determine with the imper- fect means of observation at my command, the cells are composed of two walls, the outer green or (otherwise coloured), composed of laminated cells, the inner white and structureless. Upon punctur- ing the plants a liquid is forcibly ejected. I have never been able to discover the contained cells for want of a good microscope. By placing the cake of earth sent you in a plate, and adding water enough to make it of about the consistence of potter's clay, and keeping it at a temperature above 60°, you will find a fresh crop of the plant to develop, and you will thus have an opportunity of studying them. Should you allow them to flourish, and remain uncovered in your room, you might have the satisfaction of demon- strating the "cause of ague." This fungus was first found, so far as I know, by Dr. J. P. Saftord, of Keokuk, who was kind enough to search for me while I visited an ague patient. In the locality of their growth they are to be seen in myriads, and near them, even on elevations of over 100 feet, everybody had the ague. The course of this disease seemed pari ])assu with that of the plant. Dr. John Bartlett, Chicago. * See American Journal of Medical Sciences, 1866. 96 Mycological Illustrations, by W. W.

This curious little plant, which is not uncommon in certain places in the neighbourhood of Exeter, and it is also generally distributed both in England and Scotland, has been known to botanists for a very long time, but as Dr. Greville observed in his Algae Britannic* in 1830, and I believe up to the present time, its fructification is not known, and so far as I have been able to find, the true structure, and peculiar physiology, have not been studied. Dilwyn in his" British Conferva?" p. 79 has done more to illustrate some of its peculiarities than any of the numerous writers that I have consulted, if his be really the same species that I have in view, and it differs only in one particular, and that is, he has made the underground stems in his figures septate. He says, " the joints are very long in the creeping stems," which is perfectly true. I have observed but one septum in the many specimens that I have ex- amined. Dr. Greville has very accurately described this little plant, so far as a general description goes, and which is rendered quite sufficient for its distinction, but he has gone no farther. The Doctor says, " Plant about the size of a pin's head, sessile upon the surface of the ground, covering a large space in a densely crowded manner, composed of a hollow vesicle, not homogeneous as in the genus Vancheria, but filled with a watery fluid, which escapes by an irregular terminal orifice. The receptacles at length collapse, become cup-shaped, and then cover the ground with a thin greenish crust, like that of some lichens. At its under part, each receptacle is terminated by a very short neck, which divides into a radiating tuft of pale fibres. Substance fragile and mem- branaceous, colour a pale green," and he adds to this — " The fructification of this plant is not known! Does the watery fluid contain it ? The structure of the receptacle seems minutely granular." In this description it will be observed nothing is said about the underground stems being septate. We may from this infer that Dr. Greville did not observe them. The specific name of this plant is granulatum, and as Dr. Greville and others have said, its surface seems minutely granular. Now this I have ascer- tained by careful microscopic examination to be not external, although the effect is seen on the surface of the vesicles, but it results from the pressure of the protoplasm and grains of chlorophyll on the inside. The membranes composing the walls of the vesicles, for there are two, an outer and an inner membrane, although this cannot be ascertained wTith certainty, except at the base of the vesicles and where the inner membrane begins to dry up when it shows in folds, by carrying, and the breaking up of the endochrome, into folds with it, and in the underground stems, where they are distinctly visible, they appear to me to be perfectly structureless, that is, they 104: BOTRYDIUM GRANULATDM. are thin transparent membranes only, without any cellular struc- ture, and when the plant is alive they remain distended to their very utmost from the pressure of the fluid within. The young vesicle which, as will be observed, is -only the swollen apex of a branch of the creeping or underground stem, when it emerges from the ground it is frequently only a clear transparent sac filled almost to bursting with a watery fluid ; after a time minute green spherical grains will be seen, mostly adhering in little groups to each other, and at length they take up their position on the wall of the inner membrane, until the whole vesicle appears to be filled with them ; but the vesicle being filled with them is only in appearance, as it is only the walls that are covered, with a few exceptions of granules floating in the fluid. When a full-grown plant is pressed between slips of glass and examined the membranes composing the vesicle will be seen to shrink up into folds, on which are seen the adhering granules. When the plants are full-grown the epidermis is furfuraceous, or having a number of minute scale-like processes attached to it, as if it were a very thin outer membrane broken up. These vesicles have generally been treated as separate and distinct plants, but it will be observed by the sketch, and also Dilwyn has shown, that several of these vesicles are attached to underground stems, and I find, as it has been before observed, that the vesicles are only the apices of the young branches of under- ground stems. These, then, it will be observed, are all attached, forming a kind of system, the tubular stems connecting all the vesicles together, so that we have a minute spreading underground plant whose branches rise to the surface, where they swell into little ovate or spherical vesicles. Now Dilwyn has made his plant sep- tate, or in other words, has divided the connecting tubes or stems by little nodes or rather diaphragms, consequently cutting off the communication between the different parts of the plants, so that it would be impossible for the granulose matter to traverse the tubes, except in the internodes. In my examination of groups of this plant, after having washed the stems perfectly clean, I could only detect one septum, and the tubes appeared to me perfectly free, and that the granulose matter can float freely in them. I noticed particularly that the full-grown plants contained the largest grains, with a large proportion also of minute granules, the larger generally having several of the minute ones attached to them. This led me to investigate them still further, and I now feel convinced in my own mind that the small granules are zoospores, which attach themselves to the larger or female grains, for on liberating some of these on a slip of glass and examining them carefully under the microscope, I distinctly saw the minute granules moving about as I have seen zoospores in fresh-water Algas. Finding some of the vesicles of apparently the same age as others containing only minute granules, whilst others contained both BOTRYDIUM GRANULATUM. J 05 large and small, I conclude that the small granules arc generated in distinct vesicles, whilst others contain only female grains, and also that these free or moving zoospores hare access through the tubes to the larger grains, as the tubes are all seen to be moiv or less filled with granulose matter. These Largei -tains are the means adopted by the plant fur perpetuating its species — it may not be its true fruit. The Rev. M. J. Berkeley (" Introduction to Oryptogamic Botany"), page 157, foot-note, says: — "The plant figured by Cienkowski, in Bot. Zeit. 1855, tab. XI. as Protococcus botnjoides, is probably a Botrydium, and if so, that genus pro- duces large resting-sporcs and minute swarming-spores. It is said to grow with Botrydium {Hydroga&trum granulaturri), and is certainly no Protococcus." Now, what I have stated here in regard to the smaller cells being filled with zoospores, and which appear to traverse the tubular underground stems to the larger cells, seems to confirm, to a great extent, the observations of Cienkowski. This plant has been generally regarded as of very rapid growth, and of as quickly decaying, and so far as the vesicles above ground are concerned this is true, but I believe that the underground 6tems and roots remain for a considerable time, and that at certain seasons, when a favourable hygrometric condition favours the deve- lojtment of the branches, it bursts up again with new vigour, so that it may be termed perennial. I have frequently searched to find, if possible, some of the full-grown vesicles in conjugation, similar to those of the genus Vancheria, but have never been successful. I therefore conclude that the only mode adopted to perpetuate its species is the one I have indicated above ; at the same time it would be well if observers would direct their attention to this curious little plant, and endeavour, if possible, to clear up this interesting portion of its history, for it is in these lowly forms that we detect the key to some of the more intricate structures in the larger and grander portions of the vegetable kingdom. NOTES OX THE ABOVE COMMUNICATION. By William Archer. This is a plant 1 have had but seldom an opportunity to see my- self. Any new information in reference to it would no doubt be desirable. The paper you forwarded, however, I would venture to think, while it serves to draw fresh attention to this organism, has not an a priori probability in favour of the author's conclusions, and yet there is no saying they may not be true, so unexpected phenomena sometimes offer themselves. He is no doubt right that the plantlets, if we may so say, have a mutual intercommuni- on by their subterranean branching " rootlets." Of course, as 106 BOTRYDIUM GRANULATUM. regards the author's statement that the membrane is double, one cannot say nay. I did not notice that myself, but I would venture to suppose the possibility that he may have mistaken the boundary of the shrunken-in protoplasmic contents — the so-called " pri- mordial utricle " — for an inner membrane. In several algaa this is seen, and looks very like a membrane. Still, doubtless, many algaa have laminated membranes. That immediately investing the contents remains generally firm, the outer older laminae removable or "dissolvable." The author has seen "zoospores," but while he calls them by that name he seems to regard them functionally as spermatozoids, and that these travel across from certain of the " vesicles" by the under-ground connecting tubes to certain other "vesicles," there to fertilize certain other larger "grains." It would not befit one who has not followed out his observations to say nay again to this ; but the view does not seem to have the ground of analogy. But it would not on that account be untrue. It would seem to be the case where spermatozoids occur that they are themselves generated within a more or less specialized structure, and, from which set free, that they proceed to act upon what the Germans would call a " Befruchtungskugel " — a specially differentiated portion or mass of protoplasmic matter, when fertilised an oospore — and not that in the same or an adjoining cavity one portion of the contents becomes spermatozoids, another the future oospore. Not only is the " oospore " thus a specialised body, but it is enclosed (singly or several) within a specialised " oogonium." But the Conjugates are examples of germ-cell and sperm-cell (if you admit in that group the applicability of these terms), mutually co-operating, whilst the spore is not in a specialised " oogonium " (so as to say), but both factors in the process occupy a common cavity. The author's views may not, indeed, be impos- sible. If true it would degrade Botrydium considerably below Vaucheria, where the antheridia and the oogonia are highly dif- ferentiated. The author says he has not seen anything like the " conjugation" of Vaucheria. This is surely a misapprehension of his, for " conjugation" does not take place there (comparable to Spirogyra or Mesocarpus, &c). The probability, I venture to think, is rather he has seen the zoospores (zoogonidia Aut.), not spermatozoids. Doctor Itzigsolm is stated to have seen zoogonidia. Since I came home I havn't had time to try and work up where. If the author's views were correct the larger grains would, I suppose, have necessarily to be regarded as its " true fruit," for they would be fertilised protoplasmic masses. If, on the other hand, the motile bodies be only zoospores, this plant, as regards our know- ledge of its history, would remain much in the position of several other alg£e — say, for instance, Characium, &c. As, however, the contents have been seen simultaneously segmented into individual portions, if any fertilization occurs it would be more probable that they it is that would be acted upon by spermatozoids. BOTRYDIUM GRANULATUM. 107 The following is Reinsch's account of this, given in his " Die Algenftora des mittleren Theiles von Franken," &c, pp. 218, 219: — " The plant about 1^ rn.m. diam. ; the upper portion, or that above ground, globular, gradually narrowing downwards, and pas- sing into one or two principal roots, which become gradually rami- fied into many fine rootlets ; the chlorophyll-contents at the begin- ning dense and homogeneous, and, clothing the inner cell-membrane, extends only to the neck of the root ; the membrane is rather rigid, upon being broken the cell-contents become extruded, the membrane collapses as a thick pellicle, whose contents admit of being com- pletely pressed out ; the fluid contents in this condition consist of finely-granular plasma, tinged by chlorophyll-granules. (Subse- quently the green plasma layer becomes separated from the mem- brane, breaks up into single equal-sized portions, which become rounded off, coated with a membrane, and gradually individualized as daughter-cells. At last the entire globose cell is densely filled with rounded daughter- cells ; whilst, previous to this state, the plant presented an intensely grass-green colour, it shows in this latter state a clear or sea-green colour ; mature and immature plants hence readily admit of being distinguished by the tint with the unassisted eye. The membrane of the mother-individual at last passes to decay, it collapses, and the daughter-cells become the germs of new individuals in the soil. The maturity of the indi- viduals occurs towards autumn, and accordingly the germ-cells lie resting in the earth during winter, and germinate in the following spring. The development of the germ-cells to new individuals takes place without formation of a * prothallus, ' (" ohne Vorkeim- bildung.") One end elongating as a root at once penetrates the earth, the other end becomes developed as the above-ground por- tion. The diameter of a ripe germ-cell is 0.009-0.012 rn.m. The plants prefer to establish themselves on the surfaces of the large clefts which are produced when the waters retreat and the ground becomes gradually dried by the air." The author refers to Cienkowsky's observations on " Protococcus botryoides." (Bot. Zeit. 1855.) This original paper I had not before seen ; but at this point I stopped writing this letter, and went to the Royal Dublin Society's Library and fished it up. Berkeley, I fancy, is right in supposing this really refers to a Botrydium. Cicn- kowski's figure of his plant shows " resting-spores " and " swarm- spores." His fig. 8 rather shows something very like spermatozoids ; quere then, may his " resting-spores " be really fertilised spores — true oospores ? That author does not so interpret the matter. He only refers to " swarm-spores " and " resting spores," and does not infer any analogy with Vaucheria. If fig. 8 show really spermatozoids, they escape by the bursting of the parent cell (which would then be an " antheridium") at the summit, not by i ravelling round to meet the resting-spores in a common cavity ; lor they are separate cells (possible " oogonia"). The paper 108 DICRANUM UNDULATUM. you sent I should think must be interesting, and though possibly cl priori open to some question, ought to serve to draw attention to a little-understood plant. There are some slight inaccuracies in phraseology; for one I would presume he means " spermatozoids" when he writes " zoospores," for they are physiologically and functionally distinct things. According to the " priority- laws " it would seem that this plant should pass rather as Hydrogastrum g r a i u datum (Linn.) Desv. than as Botrydium argillaceum (Wallr.). ■ — Hydrogastrum has priority over Botrydium, but the latter name is often employed in algological works, apparently without due regard to that circumstance. DICRANUM UNDULATUM {EHRHART). By R. Braithwaite, M.D., F.L.S. This may now with certainty be entered as a member of our Moss- Flora, Prof. Lindberg having detected it in Mr. Spruce's herbarium. Having recently paid a visit to that gentleman, he kindly gave me some of his original specimens, and informed me that he found it in August, 1842, growing in dryish sand-pits in a fir plantation on Stockton Forest, near York, and although speci- mens were sent to the late Mr. Wilson, it has no place in his " Bryologia Britannica." My friend Mr. Anderson, of Whitby, has found it again in the same locality a few weeks ago, and it is probable that it occurs in many other places, but, being barren, has not been distinguished from D. scoparium or D. Bonjeanii; at least, this is much more probable than that such a widely diffused Continental and American species should be totally absent from Britain. Mr. Spruce informs me that it is not uncommon in the lower Pyrenees, growing in grassy glades of sandy woods. D. scoparium is at once separated by its non-undulated leaves, and we may indicate the other two by the following diagnostic characters. Die. undulatum. Ehrt.— PL Crypt, exsic, 271 (1791),.

Schimper erroneously describes this species as having leaves " serrated on the back," so that it seems barren specimens of the two species are liable to be confounded by the best authorities. De Notaris, in his " Syllabus," points out the difficulty of distinguishing them, a difficulty which does not seem greatly lessened in our own day, especially since both are subject to considerable variation. The British specimens of D. undulatum certainly show little approach to the falcate direc- tion, usually observable in continental specimens. De Notaris, in his Epilogo della Briol. Ital. points out that La Pylaie's specimens of Dicr. palustre (Bridel Bryol. Univ. i. p. 814) belong to Campy- lopus flexuosus, and hence the name Bonjeanii is to be preferred. I hope on a future occasion to illustrate the subject of these notes by figures, and in the meantime leave the point to be further elucidated by our numerous collecting bryologists. Note on Sphagnum neglectum. — I have just received a letter from Prof. Lindberg, in which that great Bryologist informs me that he has identified Sphagnum neglectum, Angst., with an original specimen of Sph. laricinum, Spruce. This celebrated observer detected the plant in 1846, in Terrington Carr, Yorkshire, and since that time its place in the genus or its title to specific rank has never been settled ; Sph. neglectum therefore drops into a synonym, and the species must stand as Sph. laricinum, Spruce. The figure 6x in my plate, representing a section of the leaf, is erroneous, for the chlorophyllose cells are elliptic and central, just as in Sj)h. subsecwidum, to which, indeed, S. laricinum appears to stand in the relation of a sub-species. Angstrom described both S. laricinum and S. neglectum as species in the " Ofver. Vet. Ak. Iorhandl.," for 18G5, but Prof. Lindberg points out that the Lap- land specimens collected by him and published under No. 712, in Rabenhorst's " Bryotheca," as Sph. laricinum, and also those of Austin's " Mnsci Appalach," do not belong to the species, but to S. cuspidatum. Fine specimens of S. laricinum in fruit, from the Island of Aland and Stockholm, accompanied the note. — R. Braithwaite, in " Monthly Microsc. Journal." 110 BRITISH FUNGI. BRITISH FUNGI. By M. C.

Agardh, entitled " Bidrag till Florideernes Systematik," with which Algalogists in this country should make themselves acquainted. Apart from the new and systematic arrangement of the Floridea? which it contains, descriptions of new species are interspersed, and one of these is from our own coasts. The specimen was communicated to the author by Mrs. Griffiths, under the name of Nitophyllum Hillice, and is here described as follows : — Nitophyllum litteratum. J. Ag. — Stem short, cuneate ; frond rather obscurely venose beneath with dichotomous anastomosing veins, cuneato-reniform, palmately pinnatifid, lobes linear-cuneate, margin minutely undulato-crenulate, base contracted, sori seriate between the veins, more or less confluent amongst themselves, forming irregular figures. The shores of England (Mrs. Griffiths). Sori not punctiform and scattered, as in N. Hillice, but linear, oblong, or variously configurate, seriate between the veins. The substance is also thicker.

By Dr. Anton de Bary.* The existence of a sexual generation in a certain number of Fungi has latterly been demonstrated. The Mucorini offer an example of a copulation which, in my idea, and that of M. Hof- meister, is a particular form of this mode of generation ; and, since Micheli and Bulliard a multitude of Fungi are, at any rate, Bupposed to possess sexes, flowers, anthers, &c. We will first quote the Saprolegnia?, the sexual organs, and the fecundation of which were first discovered by M. Pringsheim, and described by him.f In the types which may be imagined to be monoecious, such as the Saprolegnia monoica, the Pythium and our Aphano?nyces, the female organs consist of oogonia, that is to say, of cells which are at first globose, and rich in plastic matters, which most generally terminate short branches of the mycelium, and which are but rarely seen in an interstitial position. The con- stitutive membrane of the adult oogonium in Saprolegnia monoica is reabsorbed in a great number of points, and is there pierced with rounded holes. At the same time the plasma is divided into a larger or smaller number of distinct portions which are rounded into little spheres, and separate from the walls of the conceptacle, in order to group themselves in its centre, where they float in an aqueous liquid. These gonospheres are then smooth and bare ; on their surface there exists no membrane of the nature of cellulose. In the genera Pythium and Aphanomyces, and in some of the Saprolegnia all the plasma of the oogonia is condensed into one solitary central sphere, surrounded by liquid. During the formation of the oogonium, there arise from its pedicel, or from neighbouring filaments, slight, cylindrical, curved branches, sometimes twisted around the support of the oogonium, and which all tend towards this organ. Their superior extremity is intimately applied to its wall, then ceases to be elongated, becomes slightly inflated, and is limited below by a septum ; it is then an oblong cell, slightly curved, filled with protoplasm, and intimately applied to the oogonium ; in one word, an antheridium, or the organ of the male sex. Each oogonium possesses one or several antheridia. Towards the time when the gonospheres are formed, it may be remarked that each antheridium sends to the interior of the oogonium one or several tubular processes which have crossed its side wall, and which open at their extremity in order to discharge their contents. These, while they are flowing out, exhibit some very agile corpuscles, the diameter of which is barely equal to -002 m.m., and which, considering their resemblance to what are termed " spermatozoids" in the Vaucherice, ought to # Translated from " Morphologie und Physiologie der Pilze," in Hofmeister's " Handbuch," vol. ii., cap. v., p. 155. By the Editor. t Pringsheim's " Jahrbucher," vol. i., p. 284, vol. ii., p. 205. 118 ON SAPROLEGNLE. be regarded as the fecundating corpuscles. After the evacuation of the antheridia, the gonospheres are found to be covered -with cellulose ; they then constitute so many oospores, with solid walls, if I may use an expression specially applied to the alga? by M. Pringsheim. Phenomena which are analogous in several respects and have been studied in the Vaucherice and other conferva?, as also direct observations which are due to M. Pringsheim, do not permit of any doubt but that the cellulosic membrane, which appears on the surface of the gonospheres, is only the consequence of sexual fecundation, and that this ought not to be attributed to the cor- puscles which issue from the antheridea, which would penetrate into the gonospheres, and unite with their substance. In Saprolegnia dioica and Achlya dioica, the gonospheres and the oogonia are formed in the manner we have just described ; the membrane of these latter is pierced with openings or pores, and yet no antheridia-bearing filament is seen to be applied to it. It must be elsewhere that M. Pringsheim has seen organs which everything authorizes us to qualify as antheridia. Thick tubes, similar to those which engender the zoospores, spring from the mycelium at a given moment, and are divided by septa into a series of cylindrical cells, each of which is an antheridium. In Sapro- legnia dioica, the plastic contents of the antheridia are transformed into an infinitude of very small vacillary corpuscles which escape with much agility by the orifice of a prolongation of the anther- idium, made in the manner of a neck and very short. The antheridium of Achlya dioica is cylindrical, the plasma which it encloses is divided into particles which have nearly the volume of the zoospores of the plant. These particles become globose cells, grouped in the centre of the antheridium. Posteriorly the con- tents of these latter cells are divided into numerous bacillary spermatozoids, which first break the wall of their mother-cell, and then issue from the antheridium in the same manner as the sper- matozoids of Saprolegnia dioica. These corpuscles, in the two plants of which we are speaking, resemble the spermatozoids of the Vaucherice ; they are bacillar, and their agility is assisted by a long ciliuni. It is presumable that here, as in the alga?, concern- ing which we have positive demonstration, the spermatozoids intro- duce themselves into the cavity of the oogonium, and unite with the gonospheres. On this point, however, observations are wanting, and therefore we cannot consider ourselves perfectly sure in our appreciation of the organs of which we have just treated. We may also class amongst bodies of a doubtful nature, but which are certainly worthy of further observation, the organs first seen by M. Nageli, then by M. Alex. Braun, and M. Cienkowski, and, lastly, by M. Pringsheim, who has carefully described them, and who considers them to be the probable antheridia of some species of Achlya or Saprolegnia. These bodies, according to the learned Professor of Jena, have their origin in thick filaments or ON SArROLEGNI^E. 119 tubos, similar to those which form tlie zoosporangia, ond represent so many distinct little masses of plasma in the midst of a homo- geneous and parietal ganglium ; the contents of these plastic masses are soon delineated in a more precise manner ; we sec in their in- terior some homogeneous grannies, which are at first globose, then oval, and finally pass to the enlarged and ampulla; form extremity of the generating tube ; there they become rounded or oval cells, covered with cellulose, and emit from their surface one or several cylindrical processes, which elongate towards the wall of the con- ceptacle, and pierce it, without, however, ever projecting very far beyond it. At the same time the lacunose plasma of each cell is divided into a multitude of corpuscles, the diameter of which equals about '004 m.m. ; these escape by the open extremity of the cylin- drical neck of which we have spoken, and, as regards their organization and agility, they resemble the spermatozoids of Aclilya dioica. In water these corpuscles quickly become motionless, and do not germinate. During the development of these organs, the protoplasm of the utricle, which contains them, offers at first quite normal characteristics, and disappears entirely by degrees as they increase. That these organs belong really to the Saprolegnia, which presents them and constitute its antheridia, there are good reasons to believe, as M. Pringshcim has shown. Another opinion, which the same author refutes, is that the corpuscles in question are parasites from outside, entered into the cavities of the Sapro- legnia, and which fructify at the expense of its protoplasm. This opinion relies principally on the great resemblance of these corpuscles to certain veritable parasites, such as Chytridium. It may also be supported by the fact that M. Pringsheim has some- times observed near the corpuscles in question, and in their con- ceptacles, globules similar to those which have been often met with in the Sjnrogyrce, the Vaucherice, and other Algre, and which belong incontestably to vegetables which are parasitic upon them. The reasons which M. Pringsheim brings against this appreciation ought to have lost some of their value in consequence of the new observations which have been made on the biology of microscopic parasites, and the whole subject should be studied again. More ample details concerning the sexual organs of the Saprolegnia] will be found in the already quoted works of this celebrated Algalogist. The oospores of the Saprolegnice, when they have arrived at their maturity, possess, like many other spores, a tolerably thick integu- ment, which is double, viz., formed of an epispore and an endospore. After a considerable time of repose, they originate tubular or vesicular germs, and, by exception, these germs are only as yet slightly elongated, when they produce zoospores. Hitherto it has not been possible to obtain a direct experimental proof of the reality of a fecundation in the Saprolegnia?, unless we can consider as such an instance observed by M. Pringsheim, in which the multitude of the gonospheres of a Saprolegnia perished 120 TWO SPECIES OF PEZIZA. totally from the accidental default of antheridia. However, if we consider the analogies of all kinds which exist between the organs of the Saprolegnice and those among the Algae, of which the sexual office is well known, we cannot refuse to the former the value which we grant to the latter. Experimental researches on the phenomena of sexual multiplication in the other Fungi, and on the organs which are employed in it, are barely possible. The physiological office of these latter, as sexual organs, can only be concluded from the constancy of their reciprocity of action, and from their resem- blance to the organs of Saprolegnice.

Hellbom's Lichens of Lule Lapmark. Messrs. P. J. & E. V. M. Hellbom, of Orebro, Sweden, have issued a " Centuria" of dried specimens of Lichens, collected by them in 1871, in Lule Lapmark. Unfortunately, though with printed labels, they are not numbered, so that it will be difficult to quote them as Exsiccati. For convenience sake I have numbered them in the following notes. They appear to be named after Th. M. Fries Lichenes Arctoi, but I have transposed them into the nomenclature adopted in Dr. W. Nylander's system, as that which is best known and most used in Britain. The specimens, in general, are good and characteristic, and comprise many rare and newly- detected lichens. Amongst them are many species which occur also in Britain, and the whole collection is interesting not only to the general lichenist, but also to the British lichenist, inasmuch as it identifies our insular species with those of more northern conti- nental countries, and also enables us to detect several which have not heretofore been recorded as British. The following notes made during examination and identification, before placing them in my herbarium, may prove of some value and interest : — 1. " Pyrenopsis granatina.

Judging from the black colour of the somewhat pruinose epithecium it should be referred to Lecanora Myrini, (Fr.). Th. Fries. Lich. Scand., 283, states how L. Myrini (Fr.) and L. alpina Smrft. may be distinguished, the former having a black naked or pruinose epithecium, and the latter a rufous or rufous -black epithecium, especially visible when moistened, but remarks that they may be possibly only states or varieties of the same lichen, With these criteria Richardson Arct. Am., 124, Zeo., 4, should re- present L. Myrini (Fr.), of which I possess a specimen under a different name, without locality, but probably British, from Rev. T. Salwey. L. alpina (Smrft.) will then be represented in Exs. by Arnold, 341, and 341 b., and 116, Seiner. 130; and I possess it from Cader Idris, and from Noirmont, Jersey. 126 LICHENOLOGICAL MEMORABILIA. 54.

The multi-cellular body increases by the multiplication and sub- division of its component cells, and soon assumes a globose form. The cells of the superficial layer (or simply their exterior wall, which will have to be examined anew) become polygonal, assume a yellow colour, and constitute the thin integument of the conceptacle. In the interior of this the cellular partition still continues for a long time, until finally all the utricles have become rounded oval thecae, and normally octospores.

" It is my intention, as soon as sufficient material can be accumulated, to publish l A Geographical Distribution of the British Mosses,' and in furtherance of this object I should esteem it a great favour if all collectors throughout the kingdom would kindly be at the trouble of forwarding to me, as early as convenient, complete lists of the mosses found by themselves or their friends, in their several districts, with any notes they may think desirable respecting them, and, where possible, the range and habitat of the various species.

Lichen perforatus. E.B. t., 2423. = Parmelia perforata, var. ciliata, D.C. The middle fig. with the perforated apothecia being from an exotic specimen. The true Parmelia perforata (Wulf) = P. reticulata, Tayl., is distinguished by its minutely reticulato- rimose thallus, of which the medulla gives reaction with K +, yel- low, and then red. It is very rare in Britain, though a specimen with young apothecia from Dunkerron, Ireland, occurs in herb. Brit. Mus. 2. Lichen physodes. E. B.t., 126. = Parmelia physodes and its var. labrosa, Ach. The fig. is a composite one, made up of the type and this variety, which latter is more distinctly delineated in fig. 5. Fig. 3= var. recurva, Leight. Lich. Fl. p. 126, which is a condition of var. labrosa. The var. vittata, Ach., though not drawn, also occurs in herb. Sowerby, and is referred to in the des- cription. 3. Lichen incurvus. E. B. t., 1375.= Parmelia Mougeotii (ScliEer.) The specimen drawn, is not true P. incurva (Pers.), as certain ex- pressions in the description would lead us to suppose, but a very characteristic specimen of the larger form of P. Mougeotii, con- necting it with P. conspersa. True P. incurva = Lichen multifidus, Dicks., Crypt, in., p. 16, t. 9,/ 7, is not unfrequent, though with the apothecia not very well developed on the mountains of Braemar, where also/, discreta, Nyl. pro p. occurs, but infertile. 4. Lichen encaustus. E. B. t., 2049. =Parmelia alpicola^h. Frs. The colouring of the fig. and the language of the description — " This dirty ill-looking Scotch plant, both point to P. alpicola as the species denoted, which is confirmed by the specimen in herb. * Condensed from " Journal of Botany," Dec., 1872. LICHENS OF SOWERBY'S HERBARIUM. 150 Sowerby, and the fragment attached to the original drawing. True P. e?icausta} Sm. Linn. Trans., i. p. 83, t. 4,/. 0, is a very rare species in Britain, and seems to have been gathered only on one or two of the higher Grampians in Braemar. 5. Parmelia ambigua. E. B. S. t., 279G = P. ambicjua, Ach. Nyl. and P. aleurites, Ach., Nyl. The former is represented by the two lower figs., and the latter by the two upper; the British specimens of both, which are found in herb. Sowerby, being barren, as in figs. For the correct synonomy of these two species, vid. Nyl. Animad. circa F. Arnold, in Flora, 1872, which is so far confirmed by spe- cimens in Herb. Linn. Soc. Lond. 6. Lichen ciliaris. E. B. t., 1352. = Physcia ciliaris (Linn.), and /. actinota, Ach. The specimen drawn, from Bedfordshire (Abbot), has, as is usually the case in Britain, some of the apothecia with the margin smooth, and others with it proliferous. Hence, as the margin thus varies in one and the same specimen, a separate name is not necessary for the so-called form. 7. Lichen pulvexulentus. E. B. t., 2063. = Physcia pulverulenta, var. laciniolata, mihi. Although the fig. has been referred to var. venusta, Ach., which has the apothecia crowned with short hori- zontal laciniag, yet, as these are also scattered over the thallus in the specimen drawn, as shown in the middle fig., this evidently represents a better developed condition than venusta, and may be named as above. 8. Lichen stellaris. E. B. t.} 1G97. = Physcia stellaris (?). The fig. by mistake was coloured green, vid. E. B. sub Ph. pulverulenta. Tin' specimen drawn, which unfortunately does not occur in herb. Sowerby, may, judging from the fig., belong rather to Ph. aipolia, and represent an intermediate state between the type and var. anthelina (Ach). 9. Faxmelia erosa. E. B. S. t., 2807. = Physcia erosa (Borr.), Leight. The specimen in herb. Sowerby, from Hurstpierpoint, Sussex, is evidently that drawn in E. B., and was rightly separated by Borrer from Ph. stellaris var. tribacia, Ach., with which it has frequently been confounded. 10. Lichens vixellus. E. B. t., 169G. == Physcia obscura vars. virella (Ach.), andulothrix (Ach.) Of these the former is repre- sented in the two upper figs., and the latter in the lower fig. The supposed peculiar character of ulothrix, however, is found in oilier vars. of Ph. obscura, so that it can scarcely be considered distinct. Lichen cycloselis E. B. t., 1942, is Ph. obscura (Ehrb.), sufficiently typical. 11. Lichen elaeinus. E. B. t., 2158. = Physcia adylutinata (Flk.) The specimen, drawn from the bark of trees, Sussex, shows that this is not Pannaria elaina (Whlnb.), which does not occur in Britain, but Physcia adglutinata, as observed by Borrer, E. B. S. t., 279G, descript. 160 LICHENS OF SOWERBY 8 HERBARIUM. 12. Lichen candelarius. E. B. t., 1794. = Physcia lychnea (Ach.). The specimen figured does not occur in herb. Sowerby, but frag- ments attached to the original drawing show that it is entirely as above. True Lecanora candelaria (Ach.), Nyl., is not the Lichen candelarius of our older British authors. 13. Lichen pxoboscideus. E. B. t., 522. = Gyrophora cylindrical Linn., and var. denticulata, Ach. Of these the type is represented in the two upper figs., and the var. in the two lower. The con- founding of the two species, both of which occur in herb. Sowerby, s. n. proboscideus, as observed in E. B. t., 2484 (the true pro- boscidea), was, owing to specimens of cylindrica being so named, no doubt by accident, in herb. Linnseus. 14. Lichen pellitus. E.B.t. 931. = Gyrophora poly rrhiza (Linn.). Along with the specimen figured in herb. Sowerby is one of the polyphyllus var. luxurians, Ach., which is the form usually seen in the Scotch Highlands. 15. Lichen deustus. E. B. t., 2483. = Gyrophora Jlocculosa,~H.ffm. The fruited specimen figured, from Swartz, is absent from herb. Sowerby, in which, under the same name, there appears from Scotland a specimen of G. pj'oboscidea, which is evidently the Lichen deustus of Lghft. Fl. Scot. ii. p. 861. Of G. arctica there is no specimen in herb. Sowerby, nor is this likely to have been gathered in Devonshire. CRYPTOGAMIC LITERATURE. Hobkirk, C.

Of the above G5 lichens, eight are new species, as yet found only in this district, seven are new varieties and forms ; while, exclusive of these, seven others are now for the first time recorded as British. A further exploration of the district would, no doubt, bring other varieties to light, as my attention was directed chiefly to those localities in which primary limestone is associated with mica, slate, and quartz, — a geological combination which always yields the Lichenist, everywhere throughout the Grampians, a rich and rare harvest, e.g., Ben Lawers, Movione, Crag Guie, &c. Many other interesting species were met with, and many which might have been expected to occur, such as Parmelias and Stictas, were but few in number. To those interested in the geographical distribution of our British Lichens, I may state that there is a marked contrast in many respects between the Lichen-flora of the Central Grampians in Blair Athole and that of the S.W. Grampians in Braedalbane, as also between it and that of the N. Grampians in Braemar. BRITISH FUNGI. By M. C. Cooke. ( Continued from p. 15G.) Sphaexia (Immersae) parallela. Fr. " Parallel Sphasria."

Professor Smith lias, we think, very rightly placed this genus in the family Cymbelleas, and says he may hereafter consider them as a subgenus at least of Cymbella. They are, in fact, exaggerated Cymbelleae. The present paper is a very valuable monograph of the genus Amphora, and every diatomist will look forward with impatience to the future parts of the Conspectus. The author has undertaken a work of considerable labour, and he asks for the sympathy and assistance of all those interested in the study of the Diatomacea?, and we hope that this request will be heartily responded to.

De Seynes.* Arriving at the gills, the cellular fibres, which have contributed to the formation of the parenchyma of the other parts, take a rectilinear direction, being inflected only outwardly towards the walls, in order to bear the hymenium. They fork and anastomose less than in the pileus ; still, in A. ceraceus for example, we can see the anastomosed sub-hymenial cells fork frequently, almost remind- ing us by their delicacy and their general aspect of the mucilaginous tissues of Exidia. This system of cells is not the only one in this Agaric, and stronger cells, filled with a clear yellow liquid, which colours the parenchyma, sustain this delicate trellis-work. Most frequently we see the organs which constitute the hymenium in- serted directly upon the fibriform cells more or less inflected in order to sustain them to their extremities ; at other times, one, two, three, or four spherical or polygonal cells intervene. As for the hymenium, properly so-called, its study offers numerous points of interest ; as for that of the mycelium, it is necessary, in order to find a precise and accurate description, to go back to a memoir of Mons. Leveille, read at the Philomathic Society, on the 12th of March, 1837, and inserted in the " Annales des Sciences Naturelles." The same name is given to the spore-bearing organs of the Agarics and to those of the Pezizas ; certain plates, such as those of the memoir of Dutrochet upon A. crispus, show sufficiently how necessary it was that an earnest study of them should be made. The report to the Philomathic Society upon the memoir of M. Leveille gives a just idea of its importance. The hymenium is not a membrane stretched upon the hymen o- phore ; nothing can be better isolated than its cellular elements, which are simply side by side, and in contiguity. It results from this idea, well understood, that, as the organs of reproduction are those which individualise the living being, an Agaric may be re- garded as an agglomeration of cellular fibres, varying according to the place through which they pass, and terminating in fructifying organs. Such was also the conclusion which Dutrochet deduced from his observations upon A. crispus. Three cellular organs compose the hymenium of the exosporous Ilymenomycetes. The basidium or formative and nutritive organ, analogue of the thecal amongst the Discomycetes ; a cell sometimes smaller than the basidium, sometimes of equal dimensions, which appears to me the analogue of the paraphyses ; in fine, a cell which varies much in its form and dimensions, named cystidium by M. Leveille, and of whose functions the celebrated mycologist was unaware, but which he compares to the paraphyses, whilst the other cells are named by him proper cells of the hymenium. These * Translated from his " Flore Mycologique." 8TRUCTURE OF THE GILL-PLATES OF ACJARICS. 29 latter, generally considered as simple terminations of the cells of the parenchyma, called by Hoffman sterile cells, and by Corda basilary cells, have always, for this Latter author, the same morpho- logical signification as the paraphyses. Whilst giving them this name of basilarv spores, which would seem to indicate a situation inferior to that of the other organs, Corda lias very well shown in his fine plates the real position which they occupy; one might even reproach him with having done it in a more regular and geometrical manner than occurs in nature. We readily establish this situation on the same plan, at the same height as the hasidia. The structure is the same as that oi* the fertile basidia, there are cases even in which they are all transformed into fertile basidia (" Icon. Fung.," p. 1<>, heft. ii.). There are also Pezizas, amongst which we may show that, at an advanced period of their development, the number of thecse is greater than that of the paraphyses, and in excess of the proportions which those two organs habitually bear towards each other. In the Agarics, among which the hymenium is neither too fertile nor too barren, the basidia are intermixed with the sterile cells, like the thecae in the midst of the paraphyses. Amongst the Discomycetes, the paraphyses become lengthened in such a manner that they seem to lose their analogy with the thecae ; nevertheless, intermediate stages may be observed, and I have remarked in Pe:i:a eximia a cell, which had commenced by having the dimensions of a young thecae, arrested in its development, and take the attenuated form of a true paraphysis. The paraphyses appear sometimes to "specialise" in their functions, by charging themselves with the colouring principle which gives the hymenium its proper colour ; but if the theca3 are transparent, it is because they have employed in the fabrication of the spores these same colouring matters, which can be discovered, although very diluted, amongst the latter; P. aurantia furnishes us with an example. Thus the paraphyses of the Discomycetes have their analogues in the cellules proper, and the sterile cellules of the hymenium, although they are frequently shorter than the fructifying organ, which is not the case with the paraphyses ; but this question of size does not appear to us a sufficient reason for neglecting this analogy. "In the hymenium of the Discomycetes" says the cele- brated mycologist of Prague, " the form of the envelope is the primary direction of life, and. therefore it is that paraphyses and the thecaj are on the same level ; in the hymenium of the basidia- bearing mushrooms, the increase is directed towards the exterior, and therefore the basidium is raised as well as the pollenaire above the mother cells, which replace the paraphyses. and form the surface of the hymenium.* * This consideration, expressed in a somewhat abstract manner, merits further development. If we understand it properly, it iimounts t this: among the Asconvycetes, one might say a centripetal force retains the spore, and renders it the centre to which everything converges. In effict, the theca envelope's the spore ; the paraphyses are raided, and have a tendency to envelope the theca which 30 STRUCTURE OF THE GILL- PLATES OF AGARICS. Basidia. — The basidia are cells which vary within sufficiently restricted limits ; they are in general widened towards the summit, and more or less swollen or slender, rarely of an equal size from the base to the summit. Upon the hymenium of Agaricus ceriums we have seen basidia slightly compressed at the centre to take a biventral form, but this form is rare. The basidia contain a granular liquid charged with little drops of oil, sometimes slightly coloured ; this liquid passes through the sterigmata or sporophores, little organs ordinarily four in number, superposed upon the basidia, and from the summit of which the spores originate. It is a sort of hollow funiculus, varying in length, sometimes slender, sometimes wide and funnel-shaped, and joinedto thebasidiuin by the wide part, sometimes describing a curve in the form of an ox's horn. During the early stage of the spore it is seen, as well as the sterigmata, to be filled with the granulations which were accumulated in the basidium. According to Corda, each sterigmata always develops one spore at a time, and some- times one after another ; although direct observation has not yet demonstrated this fact to me, it seems to be very probable, for we see the old basidia, which have employed their granulous contents in the fabrication of spores, present nothing in their interior but a clear and transparent liquid.* When a basidium bearing ripe spores ready to be detached is found still filled with the granulous plasma intended for the spores, it is to be presumed that it will serve for a second formation, the existing spores being entirely closed, and maintaining only a very feeble connection of endosmose with the sterigmata. We see, besides, some basidia, the plasma of which has been partly used, keep only three-fourths or a half of their cavity filled with granu- lations, as I have observed, and figured in a section of the gills of Agaricus murinus ; this diminution of the contents has very likely a connection with the number of spores formed. If we were able to assure ourselves that amongst the tetraspored basidia there are they surround ; the receptacle takes a concave form to envelope the hymenium, and this form subsists among the species with bymenophores exposed on the ex- terior (Helvella, Morcliella, &c.) by the formation of secondary or alveolous cavities. Amongst the Hymenomycetes, the spore seems, on the contrary, endowed with a centrifugal force which urges it to the exterior of the basidium ; the basidium tends to raise itself above the hymenium — at least for the whole height of the sterigmata, and most frequently, for even much more. In fine, the receptacle tends always to bear the hymenium to the exterior, by offering it the convex surfaces of gills with pointed ramifications The Exidece and the Cyphellce seem to break this law by reason of their concave shape, but it is always verified in the hymenium, and we are accustomed to meet everywhere, in the organic kingdoms, these aberrations of types which seem designed only to concur in a sort of har- monic symmetry, by recalling to us, in certain sections, and among certain groups, forms which belong to others more or less removed from them. * " Whilst the basidium, fulfilling the function which is deputed to it, gives birth to the spores, it empties itself for their use of the plastic matters which were elaborated or accumulated within it, and, when the reproductive bodies have left it, it is only a colourless cell of an extreme transparsncy." — (Tulasne, Sur V Organisation, &c.) STRUCTURE OF THE O] U.-I'LATES OF AGARICS. 31 but two generations, each of four spores, that would show another affinity with the thecae of the Ascomycetes, which produce, as is known, for the most part eight spores. There is between the theca and the basidinm such an analogue as to the terminal situation of the vegetable axis and to the production of liquid, granulous, oily contents, that we cannot but compare them completely, despite the differences in size and even of form, with products which are called upon to fulfil the same physiological function. American Ferns. In the " Bulletin of the Torrey Botanical Club," for March, 1873, Mr. D. C. Eaton describes two new species of the Transatlantic ferns : — Aaplenium Bradleyi and No- tholcena Newberryi (Eaton). The former of these plants has been found in Massachusetts and in Tennessee, by Prof. P. H. Bradley. In some of its more compound forms it is related to A. montanum, from which it differs in its larger size, more membranaceous texture, narrower outline of the fronds, and shorter stalked pinnae. Some of the denser specimens also resemble somewhat A. lanceolatum of Europe. Notholcena Newberryi has been known to Mr. Eaton for some years, but has hitherto been considered either as Cheilanth.es tomentosa or a white form of Ch. Eatoni. There is, however, no trace of an involucre, even in fruiting specimens, otherwise it bears a considerable resemblance to the ferns just referred to, but is whiter and much more tomentose. In Notholama it comes nearest N. mollis, Kze, from South America, but is much more delicate, and differs in many other important respects. Freshwater Algjc. — The April number of the " Quarterly Journal of Microscopical Science" contains a very interesting paper by Mr. W. Archer, in the form of a translation in abstract of Dr. Veit Brecher Wittrock's memoir of the "Freshwater Algae of Gotland and Oland :" two islands in the Baltic Sea. The original paper, in Swedish, was communicated in 1872 to the Royal Academy of Stockholm, and contained an enumeration of some 190 species, accompanied by four plates illustrating the Bubject. Fries' Epicrisis. — It is said that Prof. E. Fries has in prepar- ation a new edition of his "Epicrisis Systematis Mycologici." The first edition of this work was printed at Upsala in 1836-38 ; since which time numerous and important additions have been made to the species, included under the Hymenomycetes, in this, as well as in other countries. The announcement of a new edition would therefore be welcomed by mycologists in all parts of the world. 32 Mr. W. S. Sullivant. — We regret to learn from the " Journal of Botany" of the death of this eminent American botanist, which took place on the 30th April, at Columbus, Ohio, at the advanced age of 70 years. He was the author of several memoirs on the bryology of the United States, of numerous sets of actual speci- mens of American mosses, and of the " Icones Muscorum." His extensive bryological herbarium and library have, we understand, been left to the Herbarium of the Harvard University. CRYPTOGAMIC LITERATURE. Bornet, E.

BORNET'S PAPER ON THE GONIDIA OF LICHENS.* By W. Phillips. M. Bornet begins his paper by describing the structure of the thallus in Lichens, as consisting of a colourless filamentose tissue, termed hypha, and a coloured cellular portion, termed gonidia, remarking that for a long time past the great similarity of the gonidia to certain algEe had been observed, but that recent researches have thrown much additional light on the subject, tending to show this similarity to be not merely superficial or confined to a few isolated instances. M. Schwendener, in his various papers on the subject, has traced the resemblance of the gonidia to eight types of alga?, four of which belong to the group Nostocacece, and three to Chlorophyllophycece. Different methods have been suggested of accounting for the resemblance thus traced. Some have regarded it as a simple coincidence, others have looked upon the algre which correspond with the gonidia as imperfect or sterile states of true lichens, while a third party have advanced the startling theory that a lichen is a complex structure consisting of a particular kind of fungus living parasitically upon an alga. M. de Bary was the first to suggest this theory, but it was M. Schwendener who gave it shape and threw around it an air of probability. This learned savant states that he saw the filaments of the lichen-thallus (the hypha) penetrate the fronds of different algas (Sirosiphon, Nostoc and Glceocapsa) ; en- compass the gonidia with a network, similar to that with which a spider entangles his prey, and in a certain number of genera {Jtoccella, Arnoldia, Lempholemma, and P armaria) unite themselves to the gonidia by an actual junction. M. Bornet aims at confirming this theory of parasitism, looking upon it as the only one capable of explaining satisfactorily all that has hitherto been observed, and attributes its non-acceptance among Lichenologists to M. Schwendener having failed to dwell, as much as he ought to have done, on the nature of the connexion existing between the hypha and gonidia, and the mode in which it is established. Here appears to be the whole gist of the question. To demonstrate the identity of gonidia with algge is the first point ; but it is not decisive, as is proved by the opposite interpretations of the fact by MM. Famintzin and Baranetzky, who equally with M. Schwendener admit this identity. It is indispensable to show that the relations of the hypha to the gonidia are such as neces- sarily imply the idea of parasitism, and that these relations cannot be otherwise understood. To this point M. Bornet specially directs his observations, candidly admitting that it is one of the most difficult investigations that can be met with in the whole study of microscopic anatomy. * " Annales des Sciences Naturelles," 5e serie, tome xvii., ler Cahier. GONIDIA OF LICHENS. 37 M. Bornct passes in review the principal genera of the Algae which he meets with in Lichens. In the first place he examines such as contain chlorophyl [Trcntepohlia. Phyllactidium^ Protococcus), and in the second place those which contain phycochrome (Scytonema, SUgonemct) Nostoc, Glcrocapsa). Algse coloured by Chlorophyl. Trcntepohlia, Mart, comprises small algae of the group Conferva, branched like Cladophora, from which they are chiefly distinguished by not inhabiting water. They arc universally distributed on bark, wood, rocks, and mosses, attain- ing their greatesl development in moist and shady places. Their beautiful orange colour, which becomes grey when kept for some time in the herbarium, their odour of violets, or rather of Cantha- rellus cibarius, which they retain after keeping, make them easy of recognition. The great resemblance of Trentepohlia umbrina to the gonidia of several Graphidece and Verrucarice has been recognised by M. de Bary. M. Schwendener has confirmed the fact, and mentions moreover the genus Roccella, as offering the same pecu- liarity. M. Bornet has traced this resemblance in 13 genera of Lichens : — (1.)

It would be premature to make a list of species of Trentepohlia found associated with lichens, the species being as yet ill -defined, and the lichens themselves too imperfectly known, as regards this enquiry, to do so with sufficient precision. It is nevertheless cer- tain that different species furnish gonidia to lichens, some of the gonidia having more or less affinity with Trentepohlia umbrina, under which name they may be provisionally placed. If a section of the bark be made on which grows Opegraplia varia, Pers., selecting the part where the white stain of the thallua is not very conspicuous, the thallus will be seen to be com- posed of a loosely compacted tissue of filaments and yellow oval gonidia containing red-brown granules. On careful examination the hypha will be seen to extend beyond the apparent thallus, the threads diminishing in quantity, so that isolated fibres may be traced, In the same part of the bark other filaments may be seen — of a transparent green, much larger than the hypha, formed of cells placed end to end, lightly attached at each articulation. The arrangement of these cells and the mode of their increase show thai they belong to Trentepohlia. On the confines of these two vegetations we meet with some spaces where the hypha and the 38 GONIDIA OF LICHENS. Trentepohlia are mixed in such a manner that they present them- selves in the best condition for observation. The threads of the hypha fix themselves to the alga upon some part, it being perfectly indifferent whether the part be young or old, and put themselves in contact with individual cells. Often one portion only of the algal-filament, or one cell only, is touched by the hypha ; but more frequently the hypha applies itself to the surface, follows all the sinuosities of its contour, gradually throwing out lateral branches which encompass, as with arms, portions more or less large of the cells they touch. The vegetation of the hypha is stimulated by contact with the Trentepohliar, the points of contact swelling and extending, and its cells becoming shorter, produce numerous branches, which ultimately surround the alga with a dense net- work. The threads of the hypha often lie in the spaces where the cells of the Trentepohlia join each other, from which there results a constriction, causing a breaking up of the algal-filaments into fragments of different length. These the hypha transforms into gonidia, exactly similar to those in the adult thallus of the Ope- grapha. There is nothing to be seen in any part of the thallus at any period of its growth to indicate that the Trentepohlia may be pro- duced by the hypha. On the contrary, the extreme irregularity of the first connexion established between them excludes the possi- bility of such a thing, besides which they vegetate in an inverse way, and it is often the last-formed cell of the alga which is seized on by the hypha. Verrucaria nitida (Schrad.) and Roccella phycopsis (Ach.) fur- nish excellent illustrations of the same facts. Amongst exotic Lichens, Chiodecton nigrocinctum Montg., Lecidea microsperma Nyl., Byssocaulon niveum Montg., and Cwnogoninm, were examined, and contained gonidia of Trentepohlia, different from those enclosed in our indigenous species. Ccenogonium Linkii Ehrenb. presents peculiar facilities for studying this subject. The thallus is composed of articulated filaments, of a greyish -yellow in the herbarium, surrounded and held together by a network of colourless and much finer filaments belonging to the hypha. M. Schwendener regards the arti- culated filaments as those of an Alga allied to Cladophora, but M. Bornet considers them allied to Trentepohlia, and says that he has seen them invaded by the hypha from their base up- wards, the lower cells being completely enveloped by a dense network, while the upper ones were free. He has observed also, in some instances, the hypha attacking the algal filament a considerable distance above its base, leaving the inferior cells untouched. Phyllactidium, Kiitz., he considers furnishes the gonidia to Opegrapha filicina, Montg., the hypha of the lichen invading the alga at an advanced stage of its developement. He also conducted a GONIDIA OF LICHENS. 39 series of experiments with Protococcus viridis, Ag., on which were sown the spores of Parmelia parietina, Ach., with a view of show- ing thai the bypha produced from these spores attached itself to tin1 isolated cells of the alga, or to small groups of them, rejecting other bodies in their vicinity. M. Bornet, in the second place, takes into consideration Alga coloured by phyoochrome, which are distinguished from the pre- ceding, not only by their bluish-green colour, but also by the con- stant absence of a cellulose membrane, properly so called. They are widely distributed, supplying what are known as glaucogonidia, and constituting the greater part of the thalli of Phycolichenes. Their cells are diffused, grouped in colonies, or disposed end to end in moniliform filaments. The following are the genera of these alga? met with in lichens : — Calothrix, Ag., furnishes gonidia to Lichina conjinis and pygmea, Ag. Soytonbma, Ag., to Ephebella Hegetschweileri, Itzigs; St reocaulon ramulosum, Sw. (cephalodia) ; Pannaria ht/pomelcena, Nyl. ; P. triptophylla var. nigra, Nyl. ; Cocco-carpia molybdea, Pers. ; Erioderma unguigerum, Nyl. ; P. Dictyonema sericeum, Montg. Lyngbya, Ag., to Stereocaulon ramulosum. Nostoc, Vauch., furnishes gonidia to the following genera amongst the gelatinous lichens : — Collema, Ach., Arnoldia and Physma, Mass.; Leptogium, Fr. ; Obryzum, Wallr. ; and to the cephalodia of Stereocaulon, to Nephromium, Nyl., Stictina, Nyl., and to a certain number of Pannarke amongst the stratified lichens. Stigoxema, Ag., furnish gonidia to Lichenosphceria Lenormandi, Born., Spilonema paradoxum, Born., Ephebe pubescens, Fr., and to the cephalodia of Stereocaulon furcatum, Fr. Glosocapsa, Kiitz., serves to form Synalissa and Omphalaria, D.R., Phylliscum, Nyl , Cora, Fr., and is met with in certain cephalodia of Stereo- caulon. M. Bornet says lie lias established the presence of glauco-gonidia in the following 23 genera of lichens : — Ephebella, Itzigs, Lichen- osphcvria, Born.Mscr. ; Spilonema, Born.; Ephebe, Fr. ; Lichina, Ag. ; Synalissa, D.R. ; Paulia, Fee ; Omphalaria, D.R. ; Phylliscum, Nyl.; Collema, Ach. ; Leptogium, Fr. ; Stereocaulon, Schreb. (cepha- iodia) ; Nephromium, Nyl.; Peltigera, Hoffui. ; Stictina, Nyl.; Psoroma, Fr. ; Pannaria, Del. ; Coccocarpia, Pers. ; Erioderma, IV ■ : llrppia, Xa.\g. ; Cora, Fr. ; Dictyonema, Ag. (= Dichonema, X. ;il>. Esnb.) ; Verrucaria, Pers. In some species of lichens the hypha predominates in the thallus, there being only a thin stratum of gonidia below the cortical layer ; while in the others the gonidial element predominates. This differ- ence, M. Bornet thinks, corresponds, as a rule, with the mode in which the alga is invaded by the hypha. In the former, the hypha applies itself lather to the surface of the alga than to the interior, destroying its normal form, and giving the appearance of Trente- 2)ohlia and Protococcus ; while in the latter, the hypha is projected 40 GONIDIA OF LICHENS. into the frond itself, that is into the interior of the case, or gelatine, which unites the cells together. Amongst those lichens enumerated, in which the hypha applies itself to the surface of the alga, may be mentioned Stereocaulon ramulosum, Sw., the cephalodia of which were found by M. Bornet on dissection to contain long flexuous filaments of the character of Scytonema, which had been taken up and encompassed by the hypha ; also Coccocarpia molybdea, Pers., in the young fronds of which were found moniliform gonidia, disposed in long parallel threads, in which it was impossible to avoid recognizing the similarity to a Scytonema, such as were found scattered upon the bark on which the lichen had grown. Amongst the lichens he mentions in which the hypha penetrates into the interior of the alga, we have only space for one species, viz., Arnoldia minutula, Born. (sp. nov.) This lichen is very small, scarcely visible to the naked eye, pyriform or oblong, growing on the ground. On examining a thin section, the chaplets are seen to present here and there (independent of the heterocysts) some cells much larger than others, surrounded by a thick membrane. To each of these cells is fixed a short filament, a part of the general network of the hypha. The modification which these cells experience, shows the contact between them and the extremity of the inserted filament is not accidental, but that the hypha exer- cises on the gonidia an energetic action. Under its influence the cell becomes much enlarged, and surrounded with a thick mem- brane, which the ordinary cells do not possess ; this is followed by a change in the colouring matter, which separates into a grumous mass in a colourless fluid, and the side of the cell opposite the point of attachment shrivels up, till the gonidium becomes a mere dead membrane. These phenomena begin the moment the ex- tremity of a hypha-filament comes in contact with an algal- cell. In conclusion, M. Bornet considers he has established the two following propositions : — 1. Every gonidium of a lichen may be referred to a species of Alga. 2. The connexion of the hypha with the gonidia is of such a nature as to exclude all possibility of one organism being produced from the other, and that the theory of parasitism can alone explain it satisfactorily. M. Bornet's Paper is illustrated with eleven coloured plates of microscopical dissections which assist very considerably the eluci- dation of his theory.

By J. De Seynes. {Continued from Page 31.) Cystidium. — The cystidium is a coll generally larger tlian the baeidium, and which varies much in its forms ; originating from the parenchyma at the same level, or a little lower than the other elements of the hvmenium, we see it raise itself straight and soli- tary, sometimes as a simple sterile cell a little larger, sometimes in a cone more or less long or slender, sometimes bearing at its ex- tremity a little sphere (A. melinoides, A. sulcatus), sometimes dividing itself, or again growing rotund, like a leathern bottle. Tins organ does not exist amongst all the Uymenomycetes and the Agarics, notwithstanding it has been indicated by Corda as being the male organ, the antheridia, and he has given them the name of pollenaire, which has been accepted by Mr. H. Hoffmann, although this author refuses to attribute to them the same signification. It appears to me, in fact, difficult to accept this interpretation. Pretty numerous observations of these organs, some of them undertaken without even knowing the hypothesis of Corda, led me to an altogether different conclusion, and permit me to see, in the cystidia, only organs returned to vegetative functions, by a sort of hypertrophy of the basidium. Following Corda, fecundation is effected by means of a viscous liquid issuing from these organs ; but, if we remark that the examples of this kind of fecundation are taken from mushrooms (A. rutilus, viscidus, jjiucosus), all the vegetative portions of which are viscid, or have a tendency to become so in damp weather, we shall see nothing surprising in the cell belonging to them having the same property and agglutinating like the spores ; there is nothing special in this ; we should be tempted, on the contrary, to see in it an argument in favour of our thesis, and to suppose from that that the cystidia are always allied to the simple organs of vegetation. Amongst the milky Mycence (A. galopus) which have besides organs of reproduction very dif- ferent from those of the Lactaini, the cystidia shew themselves identical with those of the Lactarii ; amongst the Plutei they take the form of basidia to such an extent, that were it not for their dimensions we should take them for true basidia ; divided into short horns at the summit, they seem thus to have preserved the sterigmata. The passing of one of these organs to the other has been very well pointed out by M. H. Hoffmann, and figured in particular in the Ag. albo-brunneus. (Bot. Zeit. 1856, p. 139.) At other times the form of the cystidium approaches that of the cells of the parenchyma; in a new Agaric, Agaricus sulcatus, I have observed the cystidia forming little cylinders with swollen, spherical extremities, and that is exactly the form which the vegetative cells in the pilcus and the gills affect ; many have the form of simple 42 STRUCTURE OF THE GILL-PLATES OF AGARICS. bristles. These observations have led me to regard these organs disseminated upon the gills or frequently agglomerated near the margin, as hypertrophied basidia, returned to the functions of organs of vegetation, as we see abnormally a carpel to become a leaf. We are thus brought back to the first idea of Micheli, who called them sterile flowers, proposing only for their usage an interpretation diametrically opposed to his own. The cystidia appear to me to fulfil to the gills, the same office that the ring fulfils between the pileus and the stem ; these two organs of the same nature transmit, at their contact, prolongations which bind them together ; the gills organs of the same nature, and adjacent, have a tendency to send out prolongations to bind the one to the other. A certain number, obeying this law, are lengthened, and are diverted from their original use ; but as the ring may be very much developed or fugacious and rudimen- tary to such an extent that it seems to exist only as a reminder, or is altogether wanting, so the cystidia may be wanting, or take such a development that they are visible to the naked eye ; they fulfil, in certain cases, the functions of trabecules so well, that in separating the gills of Agaricus utramentraius, not entirely expanded, the gills divide into two longitudinal portions, instead of separat- ing the corresponding faces of two different gills. This pheno- menon is very apparent, and Delile, who was unacquainted with the cystidia, had noted the existence of fibrous prolongations binding the gills of this Agaric. It is natural to ask whether we can take advantage of the obser- vation of different forms of cystidia for the classification of the Agarics ; M. H. Hoffman concludes not. We know that there is little agreement between the form of the cystidia (pollenaire, Hoff.), and the greater part of the sections ; since they cannot be considered as organs of fecundation, and as their analogy with epidermal productions or organs of simple vege- tation is established, one can understand a priori that their impor- tance diminishes. Nevertheless, if we consider them from the point of view of the dominating form amongst a group, we shall perceive that there are still some comparisons to be effected, and that it is necessary to take account of this element of diagnosis, more especially as the observations made on this subject are still few in number, and, because, on the other hand, the sections more or less in acceptance at the present time amongst the Agarics generally, may very likely not represent their true divisions very faithfully. Thus regarded, the hymenium, which has not yet offered an organ which we may suppose in reality to be the male organ, is reduced to great simplicity : one sole and self-same organ is the basis of it ; according as it experiences an arrest of its development, as it grows and fructifies, or as it becomes hypertrophied, it gives us a para- physis, a basidium, or a cystidium ; in other terms, atrophied STRUCTURE OF THE GILL-rLATES OF AGARICS. 43 basidium, normal basidium, hypertrophied basidiam, these are tlie three elements which form the hymenium. Does itdevelope either outside the hymenium, or on the hymenium, at a time or in a part which has not yet been discovered, organs which yield pollen, spermatia, antherozoids, or any other fecundating agent ? This is what remains to be discovered. The mode of the insertion of the basidium, or of the different organs of the hymenium upon the sub-jacent tissues, conforms to two types ; but these differences are less marked in the hymenium of the Basidiospores than in that of the Thecaspores. In these last it is easy to recognise these two types, which present themselves thus. In the first, and that which appears to us the most dis- tributed, the theca, attenuated at its base, appears to have, when it has been isolated, a little pediform swelling, or, if you please, an extremity slightly recurved, provided w7ith a claw, recalling some- what the form of the crutch-shaped cells of M. H. Hoffman. It is by this little swelling that the theca is implanted upon the sub- hymenial cell. The insertions of this form offer, in section, a certain regularity. In the second type the theca is again attenuated at the base, but it gives place directly to an elongated,* line, tubular cell which loses itself in the cellulous parenchyma of the Pi ziza. There is then, at the base of the hymenium, a complica- tion which does not present at all the same aspect as the sub- hymenial tissue of the other Pezizas. The paraphyses always conform to the same mode of insertion as the thecal to which they are adjacent, and their homology thus receives from it a confirma- tion. FUCKEL'S CLASSIFICATION OF THE SPH.EMACEI. By Charles B. Plowright. Many attempts have been made to classify the various forms which are included in this extensive order ; since the genus, from which it takes its name was proposed by Haller, more than a century ago. It is not intended historically to enumerate any of these, but it should be borne in mind, that each successive author would naturally tend to adopt, or at any rate be influenced by, those suggestions of his predecessors, the convenience of which experience had demonstrated. We, in England, use almost ex- clusively the system proposed by Fries, somewhat modified ; and so familiar have we all become with it, that many years will probably elapse before we shall desire to change it. Our Continental brethren, however, have of late years introduced a multitude of new genera, many of which have been extensively adopted, and it may possibly not be uninteresting to compare some of the more im- portant of these with our own. With this in view it is proposed # At least exteriorly, for there is always an internal wall of separation. 44 CLASSIFICATION OF THE SPH^RIACEI. to give a brief account of the system employed by Fuckel in bis Symbols© Mycologies,* in which are adopted many of the more im- portant genera of Tulasne, De Notaris, Nitschke, Rabenhorst, etc. In speaking of the Sphasrias generally, Fuckel observes that they all probably pass through various stages of development ; in a few instances these are known to consist of the Conidia, Sper- mogonia, Pycnidia, and the Ascophore. It must, however, be admitted that in very many more cases nothing whatever is known of their earlier conditions, and at present but little help can be derived from this source. The Sphreriacei are, in the first instance, separated into two very unequal divisions, by the nature of the matrix upon which the in- dividual species subsist, viz., into the Vegetabilicoli and the Fimi- coli, the former embracing some 64 genera and the latter eight only. The Vegetabilicoli are divided into two nearly equal groups, the Simple and Compound. According to the system commonly adopted in this country, f the 290 species of our Simple Sphasrias are divided into 16 genera, about 200 being located in the genus Sphreria, while the remaining 90 are distributed over the other 15 genera. The Simple Sphasrias are divided by Fuckel into 37 genera, which are arranged in six groups, called respectively the Sphceriece, Ceratostomece, Pleosporece, Lasio splicer iece, Massariece, and Lopkios- tomece. The first group commences with Fries' genus Splicerella, con- taining nearly sixty members. This is followed by the genus Sphceria, composed of 40 species, of which it is remarked that " although it at present contains some very heterogenous forms, yet future investigations into the lower states of their fructification, will probably afford more satisfactory data, on which to base their separation into genera." Amongst its contents are found such species as Isothea pustula, rhytismoides and immunda, Sphaerella rusci and Sphseria corni-suecise. The second group, or Ceratostomere, includes Gnomonia, a genus of Epiphyllous Sphasrias characterised by their elongated ostiola ; it corresponds with the division Foliicolce of Fries, and, conse- quently, contains Sphreria fimbriata, tubreformis, setacea and gnomon (= U. vulgaris, De Not). Linospora is a small genus, in which Isothea saligna (Berk.) is located ; Rhapliidospora, a genus of Caulicolous Splnerias, answering to the division which has long, thread-like, more or less articulate sporidia, includes Sp. rubella, herpotricha and acuminata (= R. Carduorum, Tul.) ; Cera- tostoma, the typical genus of this group, answers to Fries' division * " Symbols Mycologicse." By L. Fuckel. Wiesbaden. 1869. f The classification here referred to, as well as the nomenclature employed, are those used in the " Handbook of British Fungi.", CLASSIFICATION OF THE BPELERIACEI. 45 of tlie same name, Sp. pilifera and cirrhosa being amongst its most important members. The third group, or Pleosporerc, takes its name from the prin- cipal genus Pleospont, which is made to embrace more species, ac- cording to Fuckel's limitation of it, than it is generally regarded as doing. For not only are those species possessing brown, muri- form sporidia, placed here (Pleospora genuina, of which Sp. herbarum is the type), but also those with fusiform septate sporidia, such as Sp. doliolum, acuta and agnita, which are classed by De Notaris in his genus Leptosphau-ia, and in addition to these it contains Sp. arundinaeea and culmifraga. A new genus, Didy- mospJuvria, receives Sp. epidermidis and diplospora. In the fourth group (Lasiosphaerieae), the typical genus Lasio- sphceria, originally proposed by De Notaris, is now made to embrace only those of the Villosaj, which have coloured, septate sporidia, such as Sp. racodium, hirsuta and hispida ; while in Leptospora are placed those with undivided sporidia, as Sp. ovina, strigosa and even Sp. spermoides. A new genus, Trichosplueria, receives Sp. pilosa. Rosellinia includes the species, with simple brown sporidia, similar to those found in the genus Hypoxylon, such as Sp. aquila, mamuiseformis, and pulveracea. The fifth group (Massariea?) has only two genera — Ejichnoa, in which are placed Sp. lanata and glis, and Massaria proper. The sixth and last group (Lophiostoinea3),into which the genera of simple Sphaerias are classed, commences with the Lophiostoma of De Notaris ; Melanomma, in which the members have small, hard perithecia, such as Sp. pomiformis and pulvis-pyrius ; Teichospora, with its brown muriform sporidia, may be regarded as being typi- fied in Sp. obducens ; Trematosphceria, in some degree answering to the Pertusce, and finishes with two genera (Bertia and Bombardia), containing but a single species in each — Bertia moriformis (Sp. morifonnis) and Bombardia fasciculata (Sp. bombardia). The division Compositi differs from our own, not only in the greater number of genera into which it is divided, but also in con- taining several specific forms" which we regard as simple Sphaerias. The first group of genera, Cucurbitariea?, contains the genus Nitschkia, consisting of three members — Cucur! itaria cupularis, Sp. tristis, and Sp. exilis. The two first of these plants are, as Fackel regards them, closely allied, and differ in little else than in the size of the sporidia and in the number of nuclei they contain. It is possible that the first named may be identical with the Sp. tristis* var. Bporidiia Majoribus, of Messrs. Berkeley and Broome. It should be observed that Fuckel is here speaking of the Sp. tristis of Persoon, Tode's plant he regards as Sp. phteostroma, Mont. A similar view, it will be remembered, was taken in the " English Flora," vol. v., part ii. * " Annals of Natural History," vol. 7, No. 42, p. 435. 46 CLASSIFICATION OF THE SPHiERlACEI. The genus Valsa is divided into sections after Nitschke : — Euty- pella, Euvalsa, and Leucostoma. It contains some 35 species, although many members of the old genus Valsa are now located in fresh genera. Thus : — Valsa tilise, Tul. = Hercospora tilice, Tul. tale la, Fr. = Aglaospora taleola, Tul. leiphemia, Fr. = Cryptospora liphcema, Tul. feuestrata, B. & Br. = Fenestrella princeps, Tul. vestita, Fr. = Thyridium vestitum, Fckl. detrusa, Fr. = Diaporthe detrusa, Fckl. pulchella, Fr. = Calosphceria princeps, Tul. quaternata, Fr. = Quatemaria Persoonii, Tul. leucostoma, Fr. = Valsa Persoonii, Nke. The genus Diaporthe (Nitschke) partakes in some degree of the characters of Valsa and Diatrype, and also includes a number of the Caulicolous Sphajrias, it being the most extensive genus amongst the Compositi. In it we find Diatrype pyrrhocystis, strumella, inasqualis, Valsa syngenesia, Innesii, Sphreria lirella, pardalota, vepris, and rostellata. Cryptosphceria, the genus originally proposed by Greville, re- ceives Sp. millepunctata. Of the species usually included under Dothidea, those found upon living leaves and grasses are placed in Phyllachora ; Rhopogrcqihus receives D. filicina ; Homostegia, D. Piggotii ; Melanops, D. melanops ; while the genus Dothidea is reserved for such species as D. rosas and ribesia. The old genus Rhizomorpha is revived, and in it is .placed Thamnomyces hip- potrichioides, with a new species allied to it. The Fimicoli, or, as they might be called, the Coprophilew, are divided into three groups. In the first the sporidia are without appendages. Cop>rolepa, a genus somewhat analagous to Hypoxylon, in possessing a more or less distinct stroma, and Hypocopra, have their simple, dark brown sporidia enveloped in a gelatinous coating. In this latter genus is placed Massaria fimeti and Sp. stercoraria. Of the other members of this group Delitschia has uniseptate, Sjw- rormia, tetraseptate, and PI eophragmia, polyseptate sporidia. The second group have their sporidia appendiculated at one extremity. It consists of two genera — Malinvernia and Sordaria. Cercophora is the name given to a new genus, the members of which have their sporidia appendiculated at both extremities. Xylaria pedunculata is for some reason not classed with the Fimicoli, although, as Mr. Berkeley has long since indicated, it is closely allied to Sp, stercoraria. The point upon which our arrangement is most open to modifica- tion certainly is, the great size of the genus Sphagna, especially with regard to the number of species included under the Obtectce, and as there are few more convenient genera than Pleospora, Eha- pidospora and Gnomonia, we can but think their adoption would prove advantageous ; while the host of minor genera, which various crypto garnists have from time to time proposed, averaging, as CLASSIFICATION OF THE Sr-HJSRIACET. 47 they do, from ono to five members, appear to as, unnecessary. Those generic distinctions too, based upon secondary forms of fruc- tification, however scientifically accurate they may be, and however natural they may appear upon paper, will be found, it is feared, not to work well in practice, because they demand a more intimate acquaintance with the life history of each plant, than it is possible, in the first instance, always to obtain. Herbarium Myoolooioum CEconomicum. — The second fasci- culus of 50 specimens has just been issued by Baron Thuemen. It fully equals in interest its predecessor, and amongst its contents are — Puccinia Apii, Cd. ; Asparagi, Link; Cerasi, Cd. ; P. coro- nata, Cd., on the oat ; P. Prostii, Duby ; on the garden tulip (Tulipa Gesneriana). Uredo Zeas, Desm., on the maize. This is probably the uredo form of Puccinia Zese, Potsch ; Uromyces Viciaa, Fckl. ; Fusarium Beta3, Rabh. ; Ustilago Sorghi, Pass. ; a new species which infests the seeds of the millet (Sorghum vulgare) ; com- municated by Prof. Passerini : Sphrerotheca Castagnei, Lev. ; on Hibiscus esculentus, from Greece ; Phacidum medicaginis, Lasch. ; (Ecidium alliatum, Rabh., on the shallot (Allium ascalonicium).

The Hollyhock Disease. — During the months of June and July this was reported from different localities in England as having caused considerable damage to Hollyhocks. It is produced by Puccinia malvacearum (Mont.), a fungus not previously observed in this country, which was originally described by Montague as oc- curring on the under surface of the leaves of Althcea officinalis. We have also received specimens on Malva sylmstris, from J. Hussey, Esq., of Salisbury j Dr. Paxton, of Chichester; and Mr. E. Parfitt, of Exeter. 48 TWO SPECIES OF FUNGI KECENTLY OBSERVED IN NORFOLK. Fuccinia Asteris.

This is a very well marked Puccinia ; the hemispherical sori are in their early stage surrounded by a yellow zone, and remain covered by the unruptured epidermis for some little time, which gives them a peculiar ashy grey colour. Dr. P. Magnus informs me this is the P. Tripolii of Wallroth, but the above name has been adopted on account of its more comprehensive character. Fuckel's plant was on the root leaves of A. amellus. I have a closely allied, if not identical species, on the leaves of some Aster, from Maine, U.S., from the Rev. E. C. Bolles. Macrospora scirpi. Fckl. — Perithecia scattered, covered by the epidermis ; ostiolum obtuse, slightly prominent ; asci large, stipi- tate, subclavate, at first innexed at the apex, then obtuse ; sporidia oblong, obtuse, 5-septate, each loculus, except the two terminal, longitudinally divided, slightly constricted, pale yellow. — Fckl.

Stirton. - The Animal Report and Transactions of the Glasgow Society of Field Naturalists, just published, contains a notice of two lichens from Ben Lawers, collected in June, 1871, which are new to the British Flora. Solorina bispoxa, Nyl. (Syn. p. 331). The spores in size and shape are characteristic, as well as the peculiar granular orisidiose appearance of the thallus in the neighbourhood of the apothecia. This lichen is more allied to S. limbata than to S. saccata. This is the first intimation of its existence in any other locality than that on the Pyrenees. Lecidea didymospora, Stirton. Nearly allied to L. sanguinarta, but differing in having two spores in each ascus, which are, besides, only half the size of those of the latter, and oval in shape instead of oblong. A section of the apothecium shows, also, a perfectly pellucid appearance, instead of the greenish tinge which pervades the hymenium of L. sanguinarta, and the thallus is more con- tinuous. The chemical reactions of the hymenium, epispore, and thallus are identical in both. The discoverer remarked, besides, that this lichen is as much entitled to a specific place as Lecidea geminata. Callithamnion hormocarpum. Holmes.— Dr. J. E. Gray writes us that in his opinion this is identical with Callithamnion versicolor, an identity which Mr. Holmes is not yet convinced of, as far as his experience of the latter plant extends. The Fungus Meeting of the Royal Horticultural Society at South Kensington, is fixed for the 1st of October, and the Fungus Foray of the Woolhope Club is finally appointed for Thursday, October 23rd, at Hereford. This latter is a correction of the date which appeared in our last number. 61 SPHAGNUM AUSTIN! In May, 1873, Dr. Braithwaite gave excellent figures, with a description of this Sphagnum, in the "Monthly Microscopical Journal," concluding with the observation, " lam indebted to Prof. Lindberg for specimens of this fine Sphagnum, which we may reasonably hope will some day be found in Scotland." In the " Journal of Botany " for September appears a letter from Dr. D. Moore to the following effect : — " I enclose specimens of Sphagnum Austini, Sullivant, which Dr. Lindberg recognised among a collection of Mosses which I made in the Island of Lewis in 1808. I had supposed the plant to be a remarkable variety of S. cymbifolium,) differing so widely from the typical form of the species as to wan ant me in making a diagnosis of its characters. It is geographically interesting to find a species not rare in North America inhabiting the Western Isles of Scotland. It grew on extensive flat boggy moors, and forms large hummocks sometimes 18 inches to two feet above the surrounding level. The following is Dr. Braithwaite's description : — Sphagnum Austini, Sullivant, in Austin's Musci Appalachian]'. Ic. Muse. Supp. i. ined., No. 2, Lindberg Contrib. ad Fl. Crypt Asia3. Bor. Or., p. 280 (1872). Dioicous; much resembling Sph. papillosum and the American Sph. Porloricejise, more or less ochraceous. Stems frequently dichotomous, dark-brown, the bark composed of four strata of cells, the outer qnadrato-hexagonal, without fibres, the inner with very fine fibres and large pores. Branches closely placed 3 in a fascicle, 2 divergent, attenuated at points, 1 pendent, short, slender, oppressed to stem; cortical cells with fine spiral fibres. Canline leaves, Ungulate, obtuse, minutely fringed at apex, the areolation as in Spjh. cymbifolium. Ramuline harts, closely imbricated, ovate-oblong, concave, more deeply coloured at apex, which is also less cucullate, but with cells strongly project- ing on the back ; cells large, the hyaline filled with fibres, and having several large foramina. The cldorophyl lose obtusely trigonous, projecting between the hyaline on the concave surface of the leaf The internal wall of the hyaline cells, where united to the chlorophyllose, densely crested with prominent papilla'. Fruit but little exserted ; peduncular bracts oblong, convolute, minutely fimbriate at the rounded apex, cells of the lower third, empty, narrow, parenchymatous, above normal, more or less fibrous, with large pores. The adjacent walls transversely striate by the large papillae. Spores ferruginous. Hat), swamps. United States. Sweden. Anthocexos laevis.— During a visit in July to the south-west of Ireland, with Dr. Lindberg, we found this rare species, not before known to grow in Ireland, in one place only near Ventry, co. Kerry. — D. Moore, in Journ. Bot. 62 CLASSIFICATION OF THE SPH^ERIACEI. By the Editor. The observations of Mr. C. B. Plowright in the last number of" Grevillea," will be interesting and useful to many of our readers, and demand but little comment. It must be expected that different workers will have different views concerning those some- what elastic terms " Genera" and " Species/' Far be it from us to assume dogmatically in this instance, and in others of a similar character, that we are right, and those who differ from us are wrong. Still, there is an observation or two which we would offer on the principles of classification generally, and on this classification of the Sphseriacei in particular that may be worthy of consideration. In the first place, is it true that because a genus, like that of Spha?ria, is so large, it becomes a duty to lessen it, by splitting it up into smaller genera ? That would seem to be the inference to be drawn from the paragraph on page 46. It seems to us that however in- convenient a large genus may be, some better grounds must be sought for its " modification." Before any attempt is made at the " modification" of a genus, we apprehend that it would be beneficial to have one or two recognized principles upon which to proceed, and, in the classification of the genus Splicer ia under new groups, having the value of genera, there seems to be one important feature which should be kept in mind. The form and segmentation of sporidia alone may be of specific, but cannot at the same time be of generic value. Want of attention to this which we hold to be a cardinal doctrine has given us a host of names for proposed genera of Spha>riacei which serve more to encumber and mystify a difficult subject than any other purpose. It may be useful to recognize groups of species having similar sporidia, as in Raphidospora, and call those groups by any con- venient or characteristic name, so long as they are recognized at their proper, and not invested with a fictitious value. We make these remarks less in opposition to our good friend Mr. Plowright than in extenuation of our own sins in not adopting in the " Handbook" a larger number of continental genera. We cannot accept the majority of genera in Sphcvria and Peziza adopted by Fuckel and others, because they are established on insufficient characters, derived solely from the sporidia. Perhaps the genus Gnomonia, including such rostellate species as Sphceria gnomon, claims recognition, but with that exception we do not yet see any good reason to amend the classification we have adopted. The division of Splicvriacei into Vegetabilicoli and Funicoli, is, we fear, a very weak point in Fuckel's classification. 63 TWO NEW BRITISH AGARICS. Described by Professor Elias Fries.

LEIGHTON'S LICHEN-FLORA OF GREAT BRITAIN, &c. Being desirous to keep my folio interleaved copy of this work duly posted up with the new species, varieties, and localities con- tinually added to our British Lichens, with a view eventually to a more perfect and comprehensive third edition, or at all events a supplement to the work, I shall feel greatly indebted to lichenists generally if they will obligingly communicate to me, either by loan or gift, characteristic and authentic specimens of any new 'finds and any other newT information relative to our Lichenology. It is only by this mutual co-operation that anything approaching com- pleteness or perfection can be obtained, and it is confidently hoped that there will be no reluctance, but rather a willing readi- among my fellow lichenists, to aid and assist with the char- acteristic liberality of all real scientific students, in every possible way at their command towards this desirable consummation. Any specimens entrusted to me for examination will invariably be care- fully and speedily returned to the owners, and I shall myself at all times be most willing in return to supply their desiderata, so far as my duplicates enable me to do so.

Fries. — This fungus has made its appearance this autumn in what would seem to be stronger force than hereto- fore, threatening some crops with destruction. It appears at first beneath the cuticle of the fruit, then breaks through in circular, often confluent, patches, of a dark brown colour, bordered by the lacerated margin of the cuticle. The microscope reveals a mass of short septate threads, which are simple, and closely packed together, each one terminating in an ovate, caducous joint, which has all the characters of a spore, and ultimately becomes at least uniseptate. The threads and spores are slightly coloured of a smoky-grey tint. From these particulars it will be seen how near Spiloccea pomi approaches to such species of Cladosporium as C. dendriticum, of which it is probably only a condition. In the " Gardener's Chro- nicle" for Sept. 20th, it is supposed to be a state of Helmiii- thosporium pyrorum. At any rate, mycologists seem to be agreed that it is not an autonomous plant, and is closely related either to Cladosporium or Helminthosporium. From our own examination, we are at present more disposed to refer it to the former than to the latter. Further investigation, at a later period, might, perhaps, modify this opinion, but at present its characters seem to ajDproxi- mate so closely to Cladosporium dendriticum, especially the variety orbiculatum, that we consider the probabilities strongly in favour of that species. — Ed.

Donkin, M.D. London — Van Voorst. 1873. Perhaps no branch of natural history, particularly that relating to the lower organisms, has occupied the attention of the micro- scopist more than the Diatomacese. The synopsis of British Diatomaceaa, by Professor Smith, was fir 8 1, and indeedtheonly English work in which any scientific arrange- ment was attempted, and since its publication (20 years ago) very many new species have, from time to time, been published in various periodicals ; a new edition of Smith's work, or a new synopsis, therefore became highly desirable. Dr. Donkin has chosen the latter alternative, and adopts an arrangement of his own. He proposes to divide the work into two portions, viz., the Introduc- tion, which will contain the natural history, classification, structure, 70 THE NATURAL HISTORY OF THE BRITISH DIATOMACE^. mode of development, and method of collecting. The second division, or synoptical portion, will give an accurate and succinct description of all known British genera and species with their synonyms. The synoptical portion is to be completed first. The first part commences with the Naviculeae, which, the author says " are by far the most numerous family of the Diatomaceae, of which they are typical, both in the structure of the frustule and the peculiar power of motion they display. . . . Two distinct and well marked types of form or development are met with amongst the Naviculeae ; in the first the valve is depressed or flattened, broad or short (in proportion to its width), the convexity behig slight and confined to near the margin. In the second the valve is elevated or convex and narrow (in proportion to its length), the convexity being great and extending from the margin to the medium line, where it is most prominent. " In reconstructing this genus and rearranging its numerous species I have adopted these two types as the basis of classification." The author follows Kutzing and other diatomists in combining Navicula and Pinnularia, and he also refers several species of Stauroneis to the genus Navicula, and he is probably right in so doing. He retains Professor Smith's term " side view" (S.V.), but abolishes "front view" (F.V.), and substitutes M.V., signifying the view of the frustule exhibiting the median connecting zone and the margin of the valves. This change appears to us to be un- necessary, as the former term was sufficiently intelligible, and has been in use for many years ; if any alteration were desirable on account of simplicity, the letters F and V would be all that are required, the former signify ing the frustular, and the latter the valvular view. In the Synopsis of British Diatomaceae, 83 species of Navicula and Pinnularia are described, 60 of which are figured. In the first three parts of the present work 104 species are figured and described, and probably one or two more parts will be required to complete the genus. We regret to say that the plates are of very unequal merit — those in Part 2 are particularly unsatisfactory — for example N. cuspidata is represented with much coarser stria? than N. fulva,, although the former is said to have 36, and the latter only 30 striae in '001. N. serians is unrecognisable, the wavy longitu- dinal striae, its most characteristic feature, not being shown. (The Author says these longitudinal markings are " plicae or folds on the valve;" this, however, is not the case. The peculiar appear- ance of the longitudinal striae are caused by the granules of which the tranverse striae are composed being placed at irregular intervals, so that the granules in one line of striae are not opposite those above and below it.) A similar arrangement occurs in the large N. rhom- THE NATURAL HISTORY OF THE BRITISH DIATOMACEJE. 71 boides (sporangia! form of Dr. Lewis). The curious decussating stria? of N. rostellum (in fact, no kind of stria? are figured) are not shown. In the description they are stated to he indistinct, 80 in "001 ; under a power of 500 diameters they are easily resolved, and are certainly not more than 55 or GO in "001.* Having thus alluded to the defects in the plates, we proceed to the more agreeable task of calling attention to their merits ; excepting those just named, and two or three others, they are far more correct than those in the Synopsis. We would particularly draw attention to the following forms : — N. liebes = N. obtusa, Sm. N.rostrata= N. tumens, Sm. (the figure in the Synopsis is totally unlike the actual form), N~. alpina, N. latiuscula = N . patula, Sm., N. nobilis and N. major are all admirably represented. In concluding these brief and imperfect remarks on Dr. Donkin's undertaking, we beg to express our best wishes for its success, and hope the publication of the parts will now proceed uninterruptedly. F. KITTON, Norwich. * We happen to know that the principal cause of the delay in the publication of the parts has been owing to the difficulty of obtaining satisfactory drawings.

Wood, JlJN.* Of all the fresh water Algse, with the exception of the diatoms, this family has attracted most attention, owing, not only to the beauty and variety of its forms, but also to their universal presence and abundance, and the ease with which their most wonderful life- histories are observed. They are exclusively, as far as known, denizens of fresh water, and preferably that which is pure and limpid. Although Mr. Ralfs states that they never grow in stagnant water, I have often found them in great abundance in such, yet never in that which was actually putrid. The same authority is also too sweeping, at least as far as this country is concerned, in stating they are never found in woods, although they are really most abundant in the open country. My experience has taught me to look for them in brick-ponds, small mountain lakes, springy fens, ditches, and, in the fall, growing among mosses and in the thick jelly composed of unicellular algae on the face of dripping rocks ; or to sum up in a word, they dwell in quiet shallow waters, for I have never found them in rapidly moving or very deep water. The single cell of which a Desmid is composed is mostly divided into two very marked similar portions, the exact counterparts one of the other, which by some have been asserted to be distinct cells. Their close union and connection, and their inherent oneness are, however, so apparent that it is needless here to spend time in demonstrating that they really are halves of one individual cell. They contain together all the parts found in the typical vegetable cell ; an outer cellulose wall, chlorophyllous protoplasm, a nucleus, starch granules and semi-liquid contents. The cell wall, or cytioderm, as it is called in this memoir, varies in thickness and firmness. During life it is mostly, if not always, colourless; but in certain species in the dead empty frond is of a reddish yellow. The markings upon it are various, and are not unfrequently al- together absent ; they are such as fine or coarse punctations, granulations of various size, stria?, furrows or elevated ribs, tubercles, obtuse or sharp, simple or forked spines, hair-like processes, umbonations, &c. These markings are within narrow limits constant in each species, and more or less peculiar, so. that they afford valuable characters to the systematist. The cytioderm itself is mostly composed of cellulose, free from appreciable inorganic matters : but in certain species contains a large amount of silex. Thus, according to De Bary, if Closterium lunula be carefully burnt upon a slide, a perfect hyaline silex cast of the cells is left. The chlorophyl is variously placed in the cell, sometimes it is arranged in lamina, sometimes in spirals, sometimes in the form of * Extracted from " A Contribution to the Natural History of the Fresh Water Algae of North America," 1873. ON THE DBSMIDIACBJ5. 7 3 radii from a central mass. These different methods afford good generic characters, and will be dwelt apoo more in detail under the various genera. The colour of the chlorophyl during active life is a vivid green, which, as the vital forces Lessen, changes to a faded yellowish tint. Naegeli and others affirm that there is always a central nucleus in the Desmid, and probably d<> so with truth, although in many instances I have found it impossible to demonstrate its presence from the size and opaqueness of the frond, crowded with endochrome, &c. In a large number of cases, however, it is very apparent. As ordinarily viewed underthe microscope, the two most striking peculiarities presented by these little plants are the motion of the whole Desmid in the water, and the various movements exhibited within the fronds. The general movement is most apparent in the larger species, which exist free and distinct in the water, especially in the boat shaped Closteria. It mostly consists of a steady, stately, slow onward movement, with sometimes backward oscilla tions. By virtue of it, Besmids in a bottle will often congregate in such positions as arc most exposed to light. There have been various theories advanced as to the cause of this motion. Ehrenberg believed that he had found foot-like processes pro- truding from the end of the frond, and giving the motile power. Others, such as Eev. Mr. Osborne and Mr. Jabez Hogg, have attributed the movements to the presence of cilia, but I think have failed so entirely to establish this that their views are more than problematical. That the motion is due to vital actions taking place, especially under the action of light, is as much as can be at present affirmed with any certainty, though it is probable that the immediate agents are endosmotic currents of gas or water. The movements of the contents within the cells are chiefly of two kinds. Taking Closterium lunula as an illustrative example, there will be found, on examination with an -Idh objective, a narrow, very transparent, and, therefore, often not very apparent layer or zone lying immediately within the cell wall, between it and the endochrome, and dipping inward in the middle of the frond, so as to communicate with the nucleus. In this zone are protoplasm, watery fluid, and scattered granules. In the ends of the fronds the different portions of this zone, meeting and widening, fill up the whole of the cavity, and, within the space thus occupied by them, there is a globular, sharply defined, still more transparent vacuole. This, some have thought to be a closed sac, with a distinct wall, but it seems really to be a vacuole lying in the midst of the inner protoplasm, which, with a few green granules, occupies more or less completely the transparent zone already described. Sometimes the chlorophyl encroaches upon this zone at the ends so as to, more or less, completely surround the vacuole, within which are always found watery fluid and granules. In the protoplasmic zone, and its vacuole, active movements are probably always present during 74 ON THE DESMIDIACE.E. active life. Streams of protoplasm appear to be constantly passing to and fro between the nucleus and the ends of the cell along the outer zone, and granules can be always seen passing backwards and forwards with an unsteady motion. When streams of protoplasm are setting very actively from the centre towards one end, there will often be an accumulation of the protoplasm there, and a consequent decided lessening in the size of the vacuole, which will again expand as the return currents arouse themselves. Within the vacuoles are seen more or less numerous smaller or larger granules in active, busy motion, swarming over and about one another with an unsteady hurrying to and fro. A form of motion, similar to this in appearance, but probably of different significance, is seen in most Desinids when in an unhealthy, feeble condition. I have seen it most marked in Cosmarium margaritaceum. In such fronds the endochrome has lost its deep green colour, and become shrunken, and lying within it is a great space containing myriads of minute, blackish particles swarming about actively. This peculiar state and appearance is by no means confined to the Desmids, for I have seen it very highly developed both in species of Spirogyra and CEdogonium. It appears to be connected with decay. Is it possible that these minute particles are foreign to the plant, vibrionic in nature ? In regard to the nature of the movements seen within a healthy Desmid, some have viewed them as exceedingly mysterious, the result of the presence of cilia, &c; but these views have been so thoroughly exploded that it is scarcely necessary even to mention them here. The movements are, in truth, precisely parallel to the so-called cyclosis of the higher plants. Protoplasmic germinal matter, wherever it exists, be it in animal or vegetable, has, as one of its distinguishing characters, the power of active, spontaneous, apparently causeless movements, and it is simply the carrying out of this power or attribute which has attracted so much attention in the Desmids, because it is in them so readily seen. There are, in this family, two distinct methods in which the species are multiplied, one with, the other without, the intervention of anything like sexuality. The non- sexual method of increase is really a modification of an ordinary vegetative process, a peculiar cell multiplication by division. In such fronds as those of the genus Cosmarium, which are composed of two evident halves connected by a longer or shorter isthmus, the first step in the process is an elongation of this neck. In a very short time there appears around the centre of this a constriction, and, I believe, an actual rupture of the outer coat. By this time a new wall has formed inside each half of the isthmus, and stretches also across its cavity, forming, with its fellow, a double partition wall, separating the two halves of the old frond. Rapid growth of the newly formed parts now takes place, the central ends become more and more bulging as they enlarge, and in a little time, two miniature lobules have ON THE DESMIDIACEJS. 75 shaped themselves at the position of the old isthmus. These are, at first, small, colourless, and destitute of all markings, Looking, as Mr. Ralls says, like condensed gelatine. They, however, rapidly increase in size and firmness, their contents assuming a grei n colour, and their walls taking on the peculiar markings of the species. At last, the parts thus formed having assumed the shape and appearance of the original lobules, the two fronds, which have been developed out of one, separate mostly before the new semi-cells have acquired their full size. What part the nucleus has in the process just described, I have never actually demon- strated, but have little doubt but that it undergoes a division in the very commencement, so that the new nucleus of each secondary frond is formed out of one-half of the old one. In proportion as the form of the Desmid becomes simpler, so do the peculiarities of its cell multiplication become less. In those species which are simple cylindrical cells, there appears to be nothing peculiar in the method of dividing, which, however, always takes place through the centre of the cell, and subsequent growth occurs, generally, only in the new found part. True sexual reproduction apparently does not take place as freely in this family as the former process, for whilst I have seen hundreds of cells undergoing the latter, it has not been my good fortune to meet with conjugating specimens on more than two or three occasions. The process has, however, been studied very closely by De Bary, Braun, Hofmeister, and others, and appears to consist generally in a rupture of the outer wall of two cells, and the protrusion of de- licate processes from an inner, often newly-formed coat, with sub- sequent union of these, and consequently of the two cells, and afterwards a condensation of the contents in the enlarged connect- ing passage. The connecting passage between the fronds is really a sporangium in which the spore is perfected, the contents of the cell finally condensing it into a firm globe, and secreting around themselves a thick coat. The after history of this spore has been very successfully studied by M. Hofmeister, whose observations were made upon Cosmarium tetraophthalmuml which he watched conjugating and forming a sort of resting spore, which was perfected early in the month of July. This was composed of a thick outer coat and green endochrome lying within as a distinct ball, nowhere in contact with the investing membranes. In three weeks time this chlorophyllous protoplasm had divided into ellipsoidal masses, or primordial cells, which soon surrounded themselves with cellulose walls, and became distinct free cells in the granular fluid which filled the cavity of the original spore. In August each of these masses was divided into two, and in the month of September the process was repeated, so that out of the original endochrome eight strong flattened primordial cells were produced. Division in some specimens ceased here, and in others took place once more, so that by the following spring all of the 7(3 ON THE DESMIDIACE.E. living sporangia contained eight or sixteen green daughter cells, each of them discoid in outline, with a strongly marked central notch. These daughter cells were finally set free by the solution of the spore wall, as Cosmaria of minute size, but agreeing in all other characters with the specific form to which they belonged. According to Braun, in the larger, more or less lunate Closteria, conjugation occurs in the following method : Two fronds approach one another in such a way that they lie back to back. In the middle of each of them there then appears an annular line or trench reaching through the cell wall, and accompanied by a distinct separation of the endochrome into two halves. Whilst these changes have been progressing there has also formed a new double wall at the position of the trench, so that out of the two Closteria two pairs of separate equal celts have been formed. Near to the larger or central end of each of these now appears a pouting trans- parent nipple like process. The corresponding opposing processes enlarging and meeting coalesce, so that the upper half of one Closterium, in the form of a daughter cell, is finally united with the upper half of the other Closterium, and the two lower halves are also joined together. Thus from a single pair of fronds arise two con- jugating pairs of cells, and finally two sporangia, in each of which a spore is perfected. This process does not seem, however, to be universal amongst the Closteria, for in many, if not all, of the smaller species, a pair of fronds produces a single sporangium. In the genus Palmoglcea, in which I have had an opportunity to study the development of the spores, the process closely simulates that seen in certain of the Spirogyra. The contents of the cells first became broken up and confused, and almost simultaneously the nucleus disappeared, the cells became swollen at one side, and slightly bent backward, so as to form jutting processes, which meeting grew together, became confluent, and developed into a sporangium much larger than either of the parent cells. Into this sporangium the contents of the latter passed, and soon became converted into a thick-walled spore, often completely filling the cavity, and apparently with its wall adherent to that of the latter.

Bryologists will be very glad to make the acquaintance of such a complete and careful synopsis as Dr. David Moore has recently produced of the mosses of Ireland. This synopsis was first pub- lished in the proceedings of the Royal Irish Academy (vol. i., ser. 2, Science), and since issued in a separate form, but as no pub- lisher's name appears on the title-page, and no price is stated, we are not in a position to affirm whether it has been published in the separate form, or only printed for private circulation. The arrange- ment adopted is lucid and distinct, generic characters are given, with tabular diagnoses of species; these are followed by ample references to full descriptions and figures, with an enumeration of the Irish localities, ending with a copious index. Altogether here are 140 compact 8vo. pages, representing such a mass of work that we should be afraid to compute the time it must have occupied in its production. This is a valuable contribution to our literature of British Cryptogams, and we can only regret that such appear so rarely. There is in Dublin a gentleman with a world-wide reputa- tion in his special subject, who could give us just such a synopsis of the Irish Fresh Water Algge ; we are not alone in the hope that Dr. Moore's example may induce him to achieve this new honour for Old Ireland. PROFESSOR (ERSTED. Dr. R. Brown has read to the Botanical Society of Edinburgh, and it is about to be published in the annual volume of " Transac- tions," a Biographical Sketch of the late Professor (Ersted, of Copenhagen. Dr. Brown was specially fitted for this duty, and has done it with all reverence for the memory of his friend. Pro- fessor (Ersted was only in the 57th year of his age, and yet by diligence and perseverance he contributed much to Botanical Science. In Cryptogams, his best known researches were amongst the Fungi, on which subject Dr. Brown enumerates thirteen contributions, prominent amongst which are those relating to the connection between Rcestelia and Podisoma. Professor (Ersted died at Copen- hagen, Sept. 3rd, 1872, after a week's illness from dysentery, having for twelve years occupied the chair of Botany in the University of Copenhagen. Fungi Britannici. — The Rev. J. E. Vize, Forden Vicarage, Welshpool, announces the publication of a fasciculus of British Fungi, including the following groups : — Puccinirei, Ca?omacei, iEcidiacei, Mucedines, and Erysiphei, making altogether 100 specimens, at the price of £1. " As a further help to beginners," he also announces, " a limited set of very good microscopical slides, showing spores, &c. ;" which will be prepared on application at 10s. 6d. per dozen. 79 The Fungus Show at SouTn Kensinoton tliis year was fully equal to, if not in some respects superior, to its predecessors. The great fault was a want of arrangement, of classification, and even of names. Still there was a goodly show of interesting species, and some that were new. Amongst the latter we observed, for the first time, an English specimen of Rhizina Icetiigata, Fries, ex- hibited by Miss Louisa Hubbard, of Horsham. There were also numerous species of Hydnum, and some very fine Polyporei. An excellent specimen of Clavaria botrytis arrived late, together with fresh specimens of Rhizina undulata, Fries. A full account of the meeting appeared in the " Gardener's Chronicle." Relation of Funoi to other Plants. — Their most common colouring matters exactly correspond with those found in the apo- thecia of lichens, and their more accidental constituents are also quite analogous to those occasionally found in the apothecia of particular lichens — for example in those of Cladonia comucopioides. According to the principles adopted in this paper, fungi ought then to be looked upon not as fronds, but as the fructification of a low type of plants, and I think that the fact of the colouring matters alone leading to such a satisfactory conclusion shows that they must have some important physiological signification. * * * * Looking upon fungi from this chromatological point of view, they bear something like the same relation to lichens that the petals of a leafless parasitic plant would bear to the foliage of one of normal character — that is to say, they are, as it were, the coloured organs of reproduction of parasitic plants of a type closely ap- proaching that of lichens, which of course is in very close, if not in absolute agreement, with the conclusions drawn by botanists from entirely different data. — H. C. Sorby, in Proc. Roy. Soc. NOTE ON SOLORINA BISPORA (Nyl.). By the Rev. J. M. Crombie, F.L.S. In recording the occurrence of this lichen on Ben Lawers, as mentioned in last number of Grevillea, Dr. Stirton is mistaken in supposing that it has not been gathered elsewhere than on the Pyrenees. A reference to Continental Lichenology would have informed him that since the date of " Ny lander's Synopsis" it had been found in the Tyrol by Dr. Arnold, and in North Italy by Professor Anzi. What, however, is of more consequence, is the specific value of the plant so named provisionally as a separate species. Dr. Nylander (Syn. p. 331), in speaking of it, says — " Forsitan tantum varietas saccatce (limbatce maxime propinqua) ; 80 NOTE ON SOLORINA BISrORA. sed quum transitum nullum vidi, earn seorsim exponere debui." Such a transition state, however, may be seen in Anzi " Exs. Langob.," 46, where the spores are 4-2 nae, and in a specimen from Killin in my own Herb. s. n. S. limbata, where, however, the thecae are usually 4-spored. S. bispora, therefore, cannot with propriety be regarded as distinct from S. limbata (Smmr ft.). This latter also, as it appears to me, has but very slight claims to be separated, otherwise than as a mere variety from S. saccata (Linn.). Certainly as seen in the " Herbarium," and having regard only to the cha- racter of the so-called thallus, it seems sufficiently distinct. An attentive observation, however, of the plant three months ago in Killin, convinced me that an opinion I had previously entertained was correct. There it grows, always associated with saccata, and not only so, but in one and the same specimen occur both the type and the variety. The former evidently passes into the latter through the decay or destruction of the proper thallus, aud the consequent growth or protrusion of an alien thallus. This latter, which is of a gelatinous nature, belongs either to an undeveloped Collema, such as C. cheileum, or a Leptogium such as L. scotinum (minor), (in which case it is Lichen spongiosus. (Sm., E. B.T., 1374.). This is frequently more or less suffused with a whitish lepraria, differing in character, on a microscopic examination, from the pruina which occurs on the thallus of the type. This alien thallus gradually destroys or takes the place of the proper one, leaving only a narrow thalline margin around the apothecia, which becomes at length isidiose or granulose. There can thus, I think, be little doubt that the species stands thus : — Solorina saccata (Linn.), with thecae 4 spored and membranaceo-papyraceous continuous thallus ; var. limbata (Smmrft.), with thecae 4, rarely 2-spored, and proper thallus interrupted, and only bordering the apothecia, its place being other- wise usurped by an alien gelatinous (collemoid) thallus.

B. .)*-* SORBY'S RESEARCHES ON CHROMATOLOGY. Mr. H. C. Sorby, F.R.S., has published, in the Proceedings of the Royal Society, some of the results of his examination of Algae and other Cryptogamia, by spectrum-analysis. We quote the fol- lowing : — Connexion of the different Groups of Alga. Perhaps I cannot choose a better illustration than that furnished by tbe different groups of Alga — the olive, the red, and the green. They contain at least twelve different colouring-matters, distributed very differently, in such a manner as to connect, and yet to dis- tinguish, the different groups very characteristically. 1 have not yet made any accurate quantitative analyses, and therefore express 102 sorby's researches on chromatology. the relative amount of the various substances by the following signs : — A relatively large quantity * A relatively moderate quantity -j- A relatively small quantity Blue chlorophyll Yellow chlorophyll , Chlorofucine Orange xanthophyll Xanthophyll Yellow xanthophyll Fucoxanthine ^ Lichnoxanthines Phycocyan Pink phycocyan Eed phycoerythrine Olive. Eed. Gi-een. + + + + + + + + + + * + * + On inspecting this table it will be seen that the olive Algce are characterized by the relatively large amount of chlorofucine and fucox- anthine, and the total absence of yellow chlorophyll, of xanthophyll, and of yellow xanthophyll. The red are especially distinguished by the colouring matters of the phycocyan and phycoerythrine groups, but also differ from the olive in containing xanthophyll and very little chlorofucine and fucoxanthine. The green are characterized by the presence of yellow chlorophyll and yellow xanthophyll, as well as by the absence of chlorofucine, fucoxanthine, and the sub- stances soluble in water, so characteristic of the red group. Blue chlorophyll, orange xanthophyll, and the lichnoxanthines are com- mon to all. It will also be seen that the red group is intermediate between the olive and the green, and, independent of the red colouring-matters, it differs from each of the other groups far less than they do from one another. It is also still more closely con- nected with each by other examples. My endeavour has been to extend such a method of comparison to all the leading classes of plants and to some of the lower classes of animals, and to ascer- tain the order in which they should be arranged, so as, in like manner, to show the most gradual and unbroken passage from one to the other. ' Connexion between the loivest classes of Animals and Plants. Comparing these various groups of Alga? with other classes of plants, and with such low classes of animals as Actinice, I found that the whole of the colouring -matters present in green Alga are those most characteristic of all the higher plants, the only difference being that in certain circumstances these latter contain in addition various more or less accidental and unessential substances, belong- ing to the erythrophyll and chrysotannin groups, some kinds of sorby's researches on chromatology. 103 which, nevertheless, do to some extent appear characteristic of par- ticular classes. As far as their constituent colouring-matters are concerned, the green Algce are therefore perfectly typical plants. On the contrary the olive Algce differ h\ a very marked manner; they contain no yellow chlorophyll, nor either of the two kinds of xanthophyll, all so characteristic of the most perfect plants, but contain chlorofucine and fucoxanthine, both of which occur in cer- tain species of Actinia?, like Anthea cereus, var. smaragdina. The presence of such colouring-matters, therefore, connects the olive Algce with the lower classes of animals, in the same manner that the presence of blue chlorophyll connects some animals with plants. Such substances, though essential to the growth of plants, arc not constant in closely allied species of animals, as though they were of no more importance for the life of animals than the accidental vegetable colouring-matters are for the life of plants. The value of these connexions between plants and animals remains to be de- termined, but in any case such definite facts must, I think, have some very important signification. If, then, according to these principles, the olive Algce be looked upon as a link connecting the lowest classes of plants with some of the lowest classes of animals, there is a perfect and simple continuity ; whereas if they were to be considered intermediate between green Algce and the higher Cryptogamia, there would be two great breaks of chromatological continuity. Changes occurring in Oscillatorice. The olive Algce are also connected in another manner with lichens, through Oscillatorice. These latter plants are extremely interest- ing, since they are subject to most remarkable changes, depending on the conditions in which they grow. I have made a series of quantitative analyses, which show this in a striking manner. I may here say that the chief difficulty in the analysis was the de- termination of the amount of the lichnoxanthines in presence of chlorofucine and fucoxanthine, and therefore the quantities given must be looked upon as only approximate, derived from several different methods, none of which were perfectly satisfactory, though they all agreed in leading to the same general conclusions. In dis- cussing the results of the analyses, it was requisite to take the amount of blue chlorophyll as uniform, since it was the only con- stituent occurring in any considerable quantity throughout the v hole series. To have taken equal weights of the plants them- selves would have been almost impossible, and would often have made those which really correspond very closely appear to differ extremely, since the constitution of the endochrome is the impor- tant question. Of course by thus calculating the results as if the amount of chlorophyll were the same in all, there appears to be an increase in some of the other constituents in the specimens exposed to the sun, due, however, in reality to a reduction in the relative quantity of chlorophyll. 104 SORBY S RESEARCHES ON CHROMATOLOGY.

On comparing together the amount of the different constituents of the same plants grown in less or more light, it will be seen that some of the differ- ances are in perfect agreement with those already described ; but the differences in the Oscillatoria? are evidently not a mere change in equilibrium, due to the decomposing action of the light, and point unmistakably to a great difference in the constructive force of the plant, depending on increased light. There is a remarkable development of phycoxan thine and orange xanthophyll, and a great decrease in the amount of chlorofucine and fucoxanthine, and the result is that we have a change almost from the type of olive Alga? to that of certain lichens. When growing in a very shady place the colouring-matters soluble in bisulphide of carbon are all iden- 80RBY S RESEARCHES ON CHROMATOLOGY. 105 tical with those in Fucus and other olive Algce, whereas when grown exposed to much sun there is a great reduction in the amount of those substances which are so characteristic of that group, and at the same time a great developement of others which are almost or altogether absent from it, but occur in large quantity in, and are very characteristic of, such lichens as Peltigera canina. The olive Algce are, however, distinguished from those Oscillatorice which approach them most closely by the absence of the phyco- cyans ; and though these occur in Peltigera, it is distinguished by the absence of fucoxanthine from those Oscillatorice which in other respects agree with it. We may also draw another important con- clusion from the above facts. Oscillatorice approach most closely to the olive Algai when their vegetative energy is the weakest, when so little light is present that they can only just keep alive. This seems to show that the colouring of olive Algce, in some way or other, belongs to a lower type than that of the green Algce, as indicated by other facts previously described. General connexion of different classes of Plants. The olive Algce are thus connected with the lowest green plants by means of two different groups of the red Algw, one leading gradually to the green Algce through Porpliyra, and the other to lichens through Peltigera. There is the same sudden break in both, where the phycocyan and phycoerythrine colours cease and yellow chlorophyll and yellow xanthophyll make their appearance — at least I have hitherto met with no good connecting links con- taining a small quantity of both instead of a normal amount of one or of the other ; and if this be really a universal fact, it would seem to show that, in some way or other, the presence of the phy- cocyans excludes yellow chlorophyll and yellow xanthophyll. Curi- ously enough this break does not occur between one great natural class and another, but in passing from those red Alga? which are so closely related to the green series as Porphyra, and from Peltigera to other lichens. So much remains to be learned of the details that it would be premature to put forward any general scheme with the expectation of its being finally adopted ; but at the same time it may perhaps be well to express what is already known, if only as a guide for further research. Of course I refer simply to the dis- tribution of the colouring-matters ; and this could hardly be ex- pected to depend upon, or accurately follow, the difference in the development of the reproductive organs ; but, on the contrary, it seems to represent something special in the constitution of the plants, for which no name has hitherto been adopted, but which I have called constructive energy. If such be really the case, an arrangement founded on chromatological characters alone would by no means necessarily agree in every particular with a natural system founded on structural peculiarities. Taking into consideration the 106 sorby's researches on chromatology. various facts described above, the following arrangement expresses every thing so far known respecting the distribution of the different colouring-matters : — Actinia. Anthea cereus, var. smaragdina. Olive group of A Igce. Red Algoe. Oscillatorice Porphyra. Peltigera. Green Algoe. Lichens. Higher Cryptogamia. Highest classes of plants. The colouring -matters found in Actinia? are very various, and it is only particular species that contain those found in Alga?. Lichens, as a whole, are characterized by a number of what may be called accidental constituents— such, at least, as occur in one species and not in another closely allied to it. Many of these are almost or quite colourless substances, which easily give rise to colouring- matters when treated with various reagents. This fact, combined with their partial distribution, is taken advantage of in studying lichens as a means for distinguishing closely connected species. Their more constant and aj)parently fundamental colouring-matters correspond with those found in the higher classes of plants, but differ considerably in relative proportion, the lichnoxanthines usually being relatively more abundant. ON SOLORINA BISPORA. By Dr. J. Stirton. By way of reply to Mr. Crombie's note on Solorina bispora (Nylj, perhaps I may be permitted to state the considerations which have weighed and still weigh with me towards the retaining of it as a species. Since detecting this lichen for the first time in 1871, on Ben Lawers, I have secured it on almost every mountain in Scotland that I have climbed of a greater elevation than 3000 feet. Accord- ingly, so far as my experience goes, it is more frequent than S. saccata, which is usually found, besides, at much lower elevations — a fact which, in my estimation, ought not to be wholly ignored in the question of specific distinction. In all these instances (four in number) the thecae are 2-spored, without exception. Occasion- ally, it is true, a one spored theca may be seen, where the spore is larger than usual, viz., as in one specimen (*1 X "054 m.m.), but, as is well known, especially in the larger spored lichens, such a state is easily accounted for physiologically, although the converse does not hold true. ON SOLORINA BISrORA. 107 Again, in S. saccata, two-spored thecal are occasionally though rarely seen in this country, mixed with the 4-spored, where such spores approach in configuration and, to a less extent, in size, those of S. bispora, but this fact, so far from militating against the spe- cific value of the latter, is, in my opinion, decidedly in its favour, and is merely a counterpart of what (as we have stated) is seen in its own internal organization. In this way is explained what is described by Anzi, and distributed by him from time to time. 3rdly. S. bispora has not the slightest relationship to S.limbata in the way which Mr. Crombie indicates, inasmuch as the so-called collemoid parasite is not present in any of the examples. The thallus, on being moistened, certainly swells more than that of S. saccata, and the particular parts in the neighbourhood of the apothecia are more isidiose, both of which characters, although apparent enough as well as distinctive, cannot, by any stretch of imagination, be construed into having any affinity with a Collema ; besides, the in- ternal organization is entirely that of the genus, and, in all the Scotch specimens, the rest of the thallus is well developed, and con- tinuous with the parts surrounding the apothecia. I am inclined to give a different interpretation from Mr. Crombie of the occasional gelatinous appearance assumed by S. saccata, and it may be, by S. bispora, and one that does not imply the rather clumsy assumption of the superposition or invasion of either a Col- lema or a Leptogium. By the way, it is somewhat puzzling to see why he has pitched on L. scotinum as the parasite. C. cheileumis in every respect a better choice ; perhaps, however, the cellular appearance of the epithallus has determined him to include samples from both genera. Some time ago my attention was arrested by seeing in two Stic- tinse from New Zealand pulpy patches of the central and older parts of their thalli. The microscope revealed the fact that the granula gonima had renewed their life, so to speak, and formed detached groups, which caused corresponding bulgings on the upper surface, while the rest of the thallus had a gelatinous appearance, as if the fibrous element (small in this section in comparison to the extent of the gonimal layer) had been nearly macerated out. In fact the whole presented very much the appearance of Sol. lirn- bata, while the surrounding parts retained their original constitution. Why granula gonima, in contradistinction to true gonidia, should have, in favourable circumstances, this increased, or rather renewed activity, I cannot explain, but the fact is, nevertheless, indisputable, of which any one may convince himself by retaining and keeping moist for a time between glass slips, portions of the thallus of a Pyrenopsis, &c. During the summer of this year, while at Killin, I noticed, as Mr. Crombie has done, a greater prevalence of the form S. limbata and always with deeply urceolated and accordingly old apothecia, as if the life of the plant had been on the decline, while the generally 108 ON SOLORINA BISPORA. wet season had served to stimulate the conglomerated gonidiac granules into renewed activity, and produced (along with the con- sequent maceration) the modified thallus in question. Had time and space permitted, I should have liked to have en- larged somewhat more on this subject ; meanwhile, I shall content myself with describing a genuine parasite on S. bispora, viz : — Lecidea epiphorbia, Stn. — Apothecia resemble, externally and internally, those of L. Parmeliarum, except that the paraphyses are neither thickened nor darker coloured at their apices, the spores are colourless, or present in a few instances, a faint tinge of yellow, and the reaction on the gelatina hymenia by means of iodine, shows a deep vinous red without any preceding caerulescent tint, instead of being negative, as in L. Parmeliarum. This lichen bears the same relationship to L. Parmeliarum that L. solorinaria does to L. oxyspora. BRITISH FUNGI. By the Editor. if' (Continued from Page 176.)

It is not purposed to discuss the advi- sability or otherwise of accepting the genus Sordaria, suffice it to say that we have here, a number of species possessing many characters in common beside that of their general fimicolous origin, and that they are arranged in a systematic manner, so that in reality it matters but little, whether they be collectively called Sphceria or Sordaria. The author includes 22 species in this enumeration, which previously were scattered over the following genera : — Sphceria, Podospora, Malinvernia, Hypocopra Coprolepa, Sordaria, and Ixocliopsis. The work commences with a history of the literature of the sub- ject, from which it appears that the first author to mention a Sor- daria was Persoon in his " Synopsis," p. 64, where we find two varieties of Sphceria Jimeti described. Herr Winter regards Sow- erby's Sphceria stercoraria as a Sporormia. This we venture to think an error. The specimen of S. stercoraria in the Hookerian Herbarium at Kew possesses simple dark-brown sporidia,f and it was determined by Rev. M. J. Berkeley, J who had the opportunity of seeing Sowerby's original specimen. Cesati and De Notaris were the first to employ the genus Sordaria, but since then almost every author has limited it in a different manner. The Morpho- logy of this genus is treated of in some very interesting remarks, upon the Stroma, the Perithecia, and the Fructification. The genus itself Herr Winter thus defines — " Stroma suberoso crastaceum, vel plerumque nullum, perithecia membranacea, pellucida, asci cylindracei vel ampli, 4 — 128-spori, paraphysibus obvallati, sporidia continua non septata, opaco-nigro- fusca." Although usually found upon dung, it is added, these plants may grow upon other vegetable substances ; one is described on wood, another on biotting-paper, and a third upon the lees of wine. The perithecia may be scattered, or crowded, superficial, immersed in the matrix, or imbedded in a stroma, of various shapes, membranaceous, and often diaphanous. The sporidia, simple, round or ovate, brown, opaque, surrounded or not by a gelatinous envelope, or appendiculated. The genus is for convenience divided into three subgenera — 1. Coprolepa = possessing a stroma. 2. Hypocopra = without any stroma, but having the sporidia in- volved in mucus. 3. Eusordaria = having appendiculated sporidia. * "Die deutschen Sordarien," by George Winter, with 5 plates. Halle, 1873. f F. Currey, " Linnean Transactions," xxiv., p. 318.

By The Bev. W. A Leighton, B.A. Camb., F.L.S., F.B.S. Ed. On the Gonidial-Zoospores of Lichens. Much attention lias been of late devoted, and is still devoted, to the subject of the Gonidia of Lichens. Two theories or opinions have sprung from these researches, which are respectively sup- ported by great and learned savans. Those whose studies are chiefly physiological maintain that the filamentous tissue of the thallus of lichens is a fungus which grows parasitically on an alga, which it envelopes and carries on with it in its growth so as to constitute the gonidia. On the other hand, true lichenologists, whilst admitting the apparent similarity of gonidia to certain algas, do not consider them as such, but as special organs of multiplica- tion or propagation of lichens. Without offering any opinion as to the merits or demerits of these two theories, the solution of the question certainly appears important, not only as regards lichenology, but botany generally, and, consequently, the least research which, tends towards this end cannot but be regarded as interesting and instructive in a scientific point of view. Five years ago Famintzin and Baranetzky published their dis- covery of the existence of zoospores which issued from the gonidia of Physcia parietina, (L.), but this fact has not been since verified LICnENOLOGICAL MEMORABILIA. 123 by others, and has been even wholly neglected and overlooked, and that with contempt, by many Bavans. To determine what becomes of the zoospores after their issue from the gonidia, M. Woronine has during two successive years (1870-1871) carried on researches on the gonidia of Physcia pvl- venrfenta, (Schrcb.), and in a paper in the Ann. des Sc. Nat., ser. 5. Bot., vol. x\i., p. 317, illustrated by tab. 14, has published the results. M. Woronine freed the gonidia from the thallus of this lichen, and cultivated them on a stage of a microscope, and kept them moistened daily with pure water. At the end of five days he saw the nucleus and the great lateral vacuole found in every gonidium to disappear, and the entire contents of the gonidium become very finely granular, and transformed into a considerable number (thirty, forty, or more) of small, round, irregular protoplastic bodies, which are the future zoospores. During this time the gonidia increased considerably in size, and on a certain part of their surface a small protuberance arose, indicating the point whence the zoospores would issue. When the zoospores were fully formed, this protuberance increased very quickly ; the membrane of the gonidium became in that point thinner and thinner, and ulti- mately absorbed, and an aperture formed, from which issued the entire mass of zoospores surrounded with a very delicate membrane. This membrane quickly disappeared, and the freed zoospores dis- persed themselves throughout the circumambient water. These zoospores are oblong and fusiform in shape, generally more or less attenuated at one extremity, which is furnished with two cilia, by means of which they move about with great rapidity. At the end of five or six hours this movement ceased, and the zoospores lost their cilia, took a perfectly round form, became covered with a membrane, their contour more definite, and their size enlarged. In about three more days these small spherical bodies assumed a decided green tint, and in each of them a small but very distinct central nucleus was observed. In fact, these small spherical bodies assumed the form of small gonidia, precisely identical with those contained in the large gonidia. In four or five days more these young gonidia, obtained from the transformed zoospores, became enlarged in size, and eventually began to multiply themselves by the usual process of reiterated and successive division. During the following five or six days these young gonidia grew considerably, but ultimately perished, probably from deficiency of nutriment. These experiments he repeated several times, and always with the same results, and he thence deduces that the zoospores pro- duced from gonidia vegetating externally to the thallus, never produce either filament or hypha, but continually give existence to new colonies of young gonidia. Such are the results of M. Woronine's researches, which appear to carry the previous researches of physiologists one step further, viz., in witnessing the conversion of the zoospores into gonidia again. 124 LICHENOLOGICAL MEMORABILIA. But now comes the question, what function do the zoospores exercise ? We know that zoospores or spermatozoids do exist in ferns, mosses, hepatica?, alga?, and probably fungi, and that they exercise in some — as yet unascertained — mode an influence in the fertilization and fecundation of the plant. Now, as the laws which the Divine Creator has imposed on organic matter are never excited into action but with some definite object, and the production of a definite result, we may conclude that these zoospores, issuing from the gonidia of lichens, exercise a definite function on these lichens. But what that action is remains to be ascertained by future experi- ments and researches. As yet we are simply in the dark. But will analogy justify us in judging it to be in some way connected with fecundation ? Very possibly. In Ann. des So. Nat. ser. 5, Bot. xv., p. 198, illustrated by tab. 8, M. Janczenski publishes a very interesting paper on the structure and development of Ascobolus furfuraceus, (Pers.), in which he shows that in the tubercular body formed on the mycelium, and which eventually developes into the cupula, there is engendered in the lower portion a series of larger cells assuming a curved, worm-like contour, which he terms Scolecite, and that from one only of the cells of this scolecite (possibly fertilized by zoospores) issue certain filamentary processes which progress upwards into the young hymenium, and there expand their extremities into young asci filled with protoplasm, which finally developed itself into perfect spores. Now, though it be but jumping to a conclusion, still we may in some measure reason by analogy that as assumedly zoospores in other tribes tend to promote or further fecundation, which takes place in the early life of the plant, as in ferns, so also these zoospores in lichens do possibly fertilize, by their movements and contact, one or more gonidial cells, and that the gonidia so fertilized give birth to the asci and paraphyses of the hymenium. At all events, the matter is worthy of consideration, although it be non proven. But then another question arises. If this be so, what are the spermogones and pycnides of lichens ? and what their functions ? Pycnides are very rare, and are regarded generally by many as parasitic fungilli. More than one kind of spermogonium has been observed on the thallus of some lichens, and it is in such case difficult to say which is the true allied one. Nor have the contents of the spermogonium, the spermatia, been ever observed to exercise any fertilizing process on the apothecia, even in a young state, and moreover they also co- exist with the mature apothecia. Are, then, these spemiogonia the male or fertilizing organs of lichens, or are they parasitic- fungilli in an incipient or imperfect state, i.e., having free spores not included in asci ? And is fertilization not effected by them or their spermatia, but rather by the zoospores proceeding from the gonidia ? Who will decide ? 125 THELOCARPON INTERMEDIELLUM. Nyl IN BRITAIN. By W. Phillips. Thelocarpon intermediellum, Nyl. The following arc the cha- racters of this minute lichen, given by Dr. Nylander, in " Flora," 18G5, p. 2G0. " Extus simile pr«cedenti (Th. Laurerii, Flot.), sed globuli paullo majores (diam. 0.2 millim.). Thecae myrios- porse, spora3 oblonga? (long 0.0035-0.0050 millim., crass. 0.0020 millim). Vulgo medio obsolete tenuiores et ntroque apice obtuse incrassatulae, paraphyses nulla;. Gelatina hymcnea iodo vinose fulvescens, thecal dilute caerulescentes." " Ad lignum alni putrescens in Finlandia media (Novvlin)." " A Th. Laureii differt magnitudine paullo majore, sporis aliis et defectu paraphysium. Adsunt filamenta ostiolaria brevia gracilia fasciculata in supera parte cavitatis perithecii (omnino sterigmata simulantia spermogonii)." To this I would add the following details from our British specimens : — Thallus thin, yellowish-green, but evanescent. Apothecia scat- tered, occasionally crowded or adnexed, yellowish-green, small, globoso-depressed and umbilicate, when mature pierced with a minute pore (fig. d.). In a careful section under the microscope, I saw the spores escaping by the pore with a jerking motion. The perithecium is externally crustaceous in texture, and very firm, pre- ferring to divide at the base when crushed, and so allowing the asci to escape downwards. The inner walls of the perithecium are clothed with minute branched threads (fig. g), which I take to be the " filamenta ostiolaria" of Dr. Nylander, but which are not confined to the immediate vicinity of the ostiolum. The asci, when perfect, are large, ventricose, attenuated in the upper part, and also at the base, and have innumerable sporidia (fig. e). They adhere so firmly to the hymenium, that if a group be pressed they spread in a radiate manner from a common centre, when the young asci can be seen in all stages of growth — bluntly clavate, cylindrical, fusiform, and as above described. The sporidia (fig. h), are very minute (0.0035- 0.0050 X 0.0020 millim., Nyl.) oblong, hyaline, obtuse at the ends, appearing to have a septum in the middle, but only apparently so. being in reality as described by Nylander, thinner in the middle portion and thickened at the apices. There are no paraphyses, a character which distinguishes this from the other species of the genus. I have tried in vain to obtain the blue reaction with iodine in the asci, which Dr. Nylander has observed in this species, ami can offer no reason for my want of success, as I use a solution strictly according with his formula. The only reaction I see is the " vinoso- fulvescent" colour assumed by the asci, as the result of their large 126 THELOCARPON INTERMEDIELLUM. absorption of the solution, which indeed can hardly be called a reaction, being merely an instance of mechanical mixture. This rare and interesting lichen, which has been hitherto found in Finland only, occurred near Shrewsbury, Dec, 1873, on the sur- face of old leather — the sole of a shoe — lying exposed in a fallow field. On showing it to my friend, the Rev. W. A. Leighton, he at once recognised it as T. intermediellum of Nylander, and afforded me every facility for comparing it with other species in his valuable herbarium. The fact will be known to British Lichenists that we owe to Mr. Leighton the discovery in this country of the only two species as yet recorded in our Flora, namely — T. Laureri (Flot.), and T. epithallinum, Leight., out of the nine species at present known in the genus. I am much gratified to be able to add T. intermediellum, Nyl., to the list of British species.

Dr. Wood has described, in his new and interesting work on the Fresh Water Algae of the United States, a new species of Masti- gonema, which he calls M. fertile. His remarks upon this species are of interest to Algologists. He says — " I found this plant in a stagnant pool in ' Bear Meadows,' forming a filamentous, felty mass, with GEdogonium echinatum and other algae. The variously curved and interlaced flexible filaments are always simple, and of uniform, or nearly uniform, diameter through their whole length ; excepting that, in some instances, there are small, local, bulbous enlargements of the sheath. Though the ends of the filaments, in all the specimens I have seen, are abruptly truncate, it is very pos- sible that in the young trichoma the apex is prolonged into a long hair, as in most of the Mastigonema. The inner filament is some- times very distinctly articulated, often, however, it is not at all so. The sheaths are firm, not at all lamellati, and generally project beyond the inner trichoma. The spores are cylindrical, yellowish, with a pretty distinct, although very close coat. They are always enclosed in distinct cells, and are mostly several in a filament, placed at intervals in its length." This is the first instance, at least that I know of, in which a species of this genus has been found in fruit, and it is interesting to note the resemblance of the spores to those of the more commonly FRUITING OF MASTIGONEMA. 127 fruiting Rivularias. At the same time the peculiar arrangement of the spores is remarkable, and it' the other species of Mastigo- nema should be found to have the more common exclusively basal arrangement of spores, I think it would afford good ground for considering M. fertile as the type of a new genus. Moreover, the filaments are not united into a distinct thallus, and also want the apical hair of Mistigothrix, so that it is very probable that they represent an undescribed genus. Until, however, the fructification of the European species is elucidated, it seems best to forbear multiplying names. HUNGARIAN FUNGI.

Nyl.— Thallus greyish-brown, thinly subgranuloso-verrucose ; spores 3-5 septate, 0,023-40 mm. long, 0,003-4 m.m. thick. On the ground, Ben Lawers (Dr. Stirton). HUNGARIAN FUNGI. In your notice of Messrs. Schulzer and Kalcbbrenner's plates of Hungarian Fungi, p. 127, you particularize one plant as Agaricus (annularia) Fenzlii. Sch. This plant comes under my subgenus Chamceota, as originally published by me in the " Journal of Botany," vol. viii., p. 213, and where I refer A. xantliogrammus, ces. to it. Messrs. S. & K. must be aware that the mere manuscript name (" Mpt.p. 1079") of Schulzer' s cannot, by any law of priority, stand, and it is the more, inexcusable from the fact of Messrs. S. & K. actually referring to my remarks published under Cham- ceota. Agaricus Fenzlii must in future stand as A. (Chamceota) Fenzlii, and this becomes more important as the many new Agarics are day after day described from different parts of the world. Professor Fries also informs me that A. macrocephalus, Schulzer, has already been described by Lasch, No. 240. WORTHINGTON G. SMITH. Ague Plant. — American Botanists are of opinion that the plant found in marshes by Dr. Bartlett, and which is considered to be intimately associated with Ague, belongs to the genus Botrydium ("Grevillea," pi. 7.), the Hygrogastrum, ol* Raben- horst. 142 THE AGUE PLANT. Dr. Bartlett has recently read before the Chicago Society of Physicians and Surgeons a communication on the Ague Plant, already noticed by us (" Grevillea," vol. i., p. 95), and of which he has given the following more minute description : — Safford's plant consists of body and what would appear to be a root. The body, or globe, consists of a wall enclosing a cavity. The layers of this wall are two ; an internal structureless envelope of a dull white color, like the retina in the cadaver, and an outer green wall, apparently resting upon the first as a basement mem- brane, which is much more complicated. It is composed of a great number of green cells ; these are circular, and enclose green contents. The contained material seems to be divided by lines running across the cell, which do not, however, display any definite arrangement. At this point of development the cells furnish the observer no indication as to the granular or cellular condition of their contents. When injured they appear to discharge other very small and greenish cells of a simpler construction. The green wall cells do not adhere very tenaciously to the white membrane. They are readily detached from the latter by gentle friction and maceration, and float off on to the root or other adjacent body. Of the construction of the cavity of the plant within the white membrane I have no knowledge. It seems to be a simple sac. The globe of the plant, at maturity, collapses, the upper circum- ference falling in upon the lower in such manner as to leave to the view a cup, in place of a sphere. At first glance it would seem that the upper hemisphere of the globe had been thrown off, and that the observer was looking into the concavity of the lower hemisphere. More careful examination will show that the globe has collapsed, its contents escaping, and the upper half of its wall falling down upon the lower. The collapsed plant generally pre- sents the cell wall unbroken. Occasionally the upper depressed half is slit open through its centre ; frequently, along the margins of the cup, at the junction of the depressed and stationary portions, there are lacerations of the wall. When the soil containing the plant is removed from its natural bed and placed in different con- ditions, the collapse of the globe seems to be precipitated. The walls, examined immediately after having fallen in, appear of a darker colour, as if moistened. The cavity of the plant contains a colorless fluid, which, it is presumed, is spontaneously evacuated when the globe collapses. It is forcibly ejected if the plant be punctured. I have never had an opportunity to examine it with a higher power than 200 ; I can therefore say nothing of its composition ; it is probably simply nutritive. Under certain conditions, as when an attempt is made to preserve the plant in glycerine, the green wall, losing entirely its cellular character, becomes rumpled up, and massed upon the inner tunic. THE AGUE PLANT. 143 The root, or wh.it seems to serve as such, is, in length, about six times the diameter of the plant. The trunk of the root soon puts forth a number of branches which seem to terminate in points, the latter becoming bulbous when soaked, as in glycerine. The root is white ami translucent ; not smooth, but having an appearance as if the surface were covered with granules. It is hollow, the fluid sometimes seen within giving the shaft the appearance of a glass tube containing water. It seems continuous with, and similar in structure to, the white wall membrane ; or rather, this mem- brane appears to be an expansion of the root material. Dr. Saf- ford regards the cavity of the root and body as continuous; he thinks lie has seen the green cells of the wall within the hollow of the root. I have never observed such an appearance. The green cells of the globe wall were often seen floating upon, under, and about the root, and massing together in its branches. In such specimens, however, it has been easy to recognize the fact that these cells have been washed from the body of the plant — the spot on the globe from which they have been removed being readily detected by the bald appearance of the denuded white membrane. The plant varies greatly in size ; perhaps the average diameter of the mature globe would measure ■£§ of an inch. They are, of course, occasionally so small as not to be detected without a lens; the largest specimens measure T]¥ of an inch. The cellular char- acter of the green w7all may be detected by a good lens, this coat appearing granular under such a power. HERBARIUM MYCOLOGICUM .ECONOMICUM.

Translated by the Rev. J. M. Crombie, F.L.S., &C Dr. Nylander, in noticing in the "Flora," 1874, No. 4, two recent pamphlets by Dr. Weddell, makes the following very op- portune observations on several most important matters relating to Lichenology, which with several additional notes, he has requested me to translate for insertion in " Grevillea." The pamphlets under review are : — I. — H. A. Weddell, " Les Lichens du massif granitique de Liguge " (Extrait du " Bulletin de la Societe Botanique de France/' 1873). II. — H. A. "Weddell, "Nouvelle Revue des Lichens du Jardin public de Blossac, a, Poitiers " (Extrait des " Memoires de la Societe" des Sciences Naturelles de Cherbourg," 1873). Since what I have elsewhere written is true, " that truth itself consists in the continual demolition of errors," I have always be- lieved that it tends very much to the interests of science to oppose fanciful or erroneous opinions ; nay, it may legitimately be con- sidered to be one's duty to point out and refute such opinions, for the.progress of science depends not a little upon their subversion. Nothing, indeed, as is evident, is more readily received and propa- gated than erroneous opinions, and, conseqnently, there is so much greater difficulty in opposing their propagation, though we may not on that account depart from the duty. The two writings, whose titles are given above, forsaking on certain points the truth and exactness of science, present a handle for some animadversions, of which the following are, I think, especially useful and opportune where they touch upon modern controversies. I. Here, in the first place, we find (p. 5) these words — " Recent observations introduce to our notice singular relations which exist between Lichens and Alga?," &c. From this it would appear that the author, in his own way, assents to the Schwendenerian hypo- 146 NYLANDER ON THE ALGO-LICHEN HYPOTHESIS, &C. tliesis. Those, however, who have promoted it have brought forward nothing confirmatory of it, but only anatomical reasons long ago well known (they have introduced nothing). The absur- dity of such an hypothesis is evident from the very consideration that it cannot be the case that an organ (gonidia) should at the same time be a parasite on the body of which it exercises vital functions ; for with equal propriety it might be contended that the liver or the spleen constitutes parasites of the Mammiferce. Parasite existence is antonomous, living upon a foreign body, of which nature prohibits it from being at the same time an organ. This is an elementary axiom of general Physiology. But observation directly made teaches that the green matter originally arises within the primary chlorophyll —or phycochroui — bearing cellule, and consequently is not intruded from any external quarter, nor arises in any way from any parasitism of any kind. This, in a note *' Upon the Gonimic Evolution of the Collemaeei " (" Flora," 1868, p. 353), I have already enunciated, and in vain can it be denied. The cellule at first is observed to be empty, and then, by the aid of secretion, green matter is gradually produced in the cavity, and assumes a definite form. It can, therefore, be very easily and evidently demonstrated that the origin of green matter in Lichens is entirely the same as in other plants. What need is there then of any fuller refutation of the but too notorious hypo- thesis of Schwendener ? In a note under this paragraph, Nylander adds — " To those desiring somewhat longer explanations upon this subject, I may transcribe the following observations which I have elsewhere made : — ' In this place may be noticed the hypothesis, or singular conjecture, which, confirmed by no certain observations, and de- pending upon no valid grounds, amongst other statements, exhibits Scytonemata insinuating themselves into the thalli of Pterygium (erroneously termed P armaria in Schwend. Erorter, in " Flora," 1872, t. 4). Those Scytonemata are explained as ' Alga?,' which, in a most wonderful manner, are parasitic in Pterygium." But did not the author in conceiving such a theory know that the Scytone- mata are (as is proved by the genus Gonionema), rather Lichens than Alga? ; so that he was by no means treating of the parasitism of an Algal on a Lichen, but of a Lichen on a Lichen. Moreover, the Scytonemata present a gonimic vagina much firmer than the Scytonemoid syngonimia of the Pterygia, and consequently the Schwendenerian assimilation is entirely erroneous. In opposition to the affirmation of this author, I may also add that no free Scytonemata are to be seen in the specimens cited as received from Tuckerman, and which I also have received. And if there were any truth in his seeing anything of the kind, we would reason from it that Lichens would grow best and occur most abundantly in places where Scytonemata and other " Alga?," regarded as " para- sitical" gonimic, or gonidial elements of Lichens, abound, and NTLANDEB ON Till'. ALi;o-i.[iilKN HYPOTHESIS, &0. 147 would then be there observed crammed with these elements. The case, however, is far otherwise; for, on the contrary, such stations arc avoided by Lichens, and are not inhabited, except Bparingly by Collemacei ami a few others, which are not always well developed ; nor do those which occur contain any para- sites of that kind in their texture. Elsewhere I have adduced that the gonidia and gonimia of Lichens constitute a normal organic system necessary, and of the greatest physiological im- portance, so that around them we behold the growing (or vege- tative, if we may so term it) life chiefly promoted and active. a< for example creating colorific matter. On the contrary, thofi I portions of the thallus remote from the gonidia and more advanced in age, as best appears in incrassate crustaceous lichens, having lost their life, become entirely tartareous, forming, as it were, but " thickened deposits." Thus the life is collected chiefly in the parts around the gonidia (in the thin superficial stratum). Moreover the lower, and but little gonidiose lichens, such as often occur amongst the llielotrejnata, Graphides, Vetrucarice, Mijcopora, have but a shorter life, and consequently are frequently found with the apo- thecia either not rightly developed, or dead, and thus in this respect manifesting an analogy with and verging towards the fungi. It would be most inconsistent to admit that parasitic plants dis- charge the function of organs within the plant which they invade. Other and additional arguments against the parasitic hypothesis of Schwendener may be seen in Caspary, " Ueber, dieneuren Ansich- ten in Betreff der Flechten, monach diese Schmarotzer seieu in Schriften der physik. okon. Gesellschaft in Konisberg, 1872, Abth. ii., p. 18." I add nothing here concerning the hymeneal gonidimia, which, without any "hyphae," and the hyphre of fungi have certainly nothing common in structure with the " hyph®" of lichens *, normally occupy the pyrenocarpous thalamia, which are destitute of paraphyses, between the thecte of many species, and nothing of the Friesiads or the gonimia of cephalodia, which simi- larly constitute normal organs, and afford constant characters of different species (not only in Stereocaulon and Pilophoron, but also in Peltidea, Placopsis, Lecidea panceo/a, &c). It certainly seems superfluous to delay longer in refuting an hypothesis of that kind. But even though the gonidia of lichens should show an analogy with the gonidia of " xYlgai" (and what is clearly known of the full development or fructification of those algae treated of?), this cir- cumstance would present nothing marvellous, and certainly would not confirm any subversive theories. But it is not to be overlooked, that under the name of Algae are received by authors plants wholly ambiguous in their nature, and such, indeed, as are very near to * Here the author ad>ls in my copy — " The anatomical filamentose elements of lichens are distinguished by various characters from the hyphae of fungi. They are firmer, elastic, and at ouce present themselves in the texture of lichens. On the other hand the hjpha3 of fungi are very soft, they possess a thin wall, and are not at all gelatinous, while they are immediately dissolved by the application of hydrate of potash, i\ Weddell says, in a note — " The oxalate of lime constitutes . . . one of the essential characters of this class of plants." This is an error, for the occurrence of oxalate of lime in octohedral crystals is not to be regarded but as a character in doubtful cases, distinguishing the thallusof a lower Lichen from those Fungi which it resembles. But oxalate of lime is especially peculiar to certain medullas (vid. Nyl. Syn., p. 11); on the other hand, it is entirely absent — for example, in the Collemacei, as is shown in every microscopical drawing of their thalli yet published, and which is altogether elementary. Elsewhere 1 have indicated (Nyl. Obs. Peziz. Fenn., p. 37), under Peziza amentacea, Balb., " The hypothecium contains crystals of oxalate." II. "With respect to the Lichens of the public garden of Blossac com- pared with my note concerning those of the garden of the Luxem- bourg, at Paris, I may observe that my intention in it was only to show what Lichens might be found in the midst of a very large city,* which can in no way be compared with the vegetation of a town which entirely presents the vegetation of the neighbouring rural tracts. Concerning chemical re-agents, we find it laid down — •' The truth is, an experience of many years permits me to affirm that there are some things in the new method to accept and some to reject." We may expect to learn from the experience of the author, what, in his judgment, are to be rejected, and what, on the contrary, are to be approved of or retained. Also the incomparable writer of Upsala, thinking in former publications, 11 the reactions fallacious and variable," and " of little or no im- portance," lately confesses and kindly concedes, that " he does not entirely despise this character, sometimes as auxiliary" (that is nearly sub-auxiliary) " Scand.," p. GO ; nevertheless, he expounds no better character in his writings, and most eagerly adduces the chemical characters indicated by me, than which none others are indeed more constant. He looks down upon them, but he lays hold of them.f The naked truth is (" la verite est") that the * Not a single Lichen, and scarcely even the trace of any thallus, are to be perceived in any of the public parks of London. — J. M. C. t In the same place there occur these words — " It would be incongruous if lichens and not also other plants could be distinguished in this way." But the opinion may rather be regarded as incongruous, which would maintain that lichens in this respect are of an identical nature, for they show a nature altogether pecu- liar. Nor may it be overlooked that in Th. Fr. " Scand.," p. 187, there is openly announced " a new discovery." The author declares that he has employed acetic acid as a reagent " with great success." He may not, therefore " despise" this lucky acetic acid, but happily use it. The next time he will no doubt reveal won- derful things effected by the help of this acid, and what splendid successes he has obtained. 152 NYLANDER ON THE ALGO-LICHEN HYPOTHESIS, &C. chemical characters are entirely similar, and of similar value with the other characters ; all are auxiliary, but the former excelling in simplicity and perspicuity, are at the same time very easy and necessary. Accordingly in the present state of Lichenography, we may not neglect them, or if we do neglect them, the whole of Lichenography would become worthless and profitless. But it is of the greatest importance that those as well as the other characters should be rightly and accurately observed ; for, if badly and un- skilfully employed, they lead to errors ; as happens through any defect of dexterity and sound judgment in matters relating to science, and nowhere is expertness and judgment more necessary. In p. 16, we read, " I have seen in some apothecia of this variety, or of the following, the normal spores of Lecanora subfusca replaced by the spores in equal number of an entirely distinct physiognomy — spores twice as large, brown, 1-septate, without apparent change in the other portions of the apothecium. M. Nylander, to whom I submitted pieces, has hesitated to pronounce upon the possible causes of such an anomaly." Here the experience of the author by no means shines forth. He had, indeed, submitted to me hete- rogeneous apothecia, growing mixed with the apothecia of a certain " Lecanora subfusca" saying on a label, " apothecia L. subfusca?., bearing different spores (brown, 1-septate)," an absurdity unworthy of any lichen whatever, or any other plant. I answered, "this is something marvellous ; I have known nothing so prodigious." This the author does not seem to have understood, nor very faith- fully rendered. " Nylander has hesitated, &c," when on a more attentive examination, the wonderful knot could easily be solved. Manifestly it relates to two lichens occurring conjointly, as is every day seen, with the thalli so intermingled that the different apothecia appear as if sitting on the same thallus.* Examining to-day those apothecia which were sent, it was at once evident that the apothecia with the brown spores belonged to Physcia aipolia. Accordingly, Lecanora subfusca was growing mixed with this Physcia, which was the " wonder." It may be added that, in no respect, either external or anatomical, do the apothecia of both present any likeness. f * This is equally the case, and perhaps even more frequently so with the spermogones, which it cannot be doubted are as constant in their chai'acter in the different species as are the apothecia. Inattention to this has led Dr. Lindsay to propound his very erroneous theory of the " Polymorphism of Spermogones." — J. M. C. f It may be observed that lichens occurring without any thallus, or as para- sites of other lichens, are of a very low order; the inferior Lecidece (nearly Patel- larice, scarcely any Biatora), Opegraphce, Artlwnice, Melaspilece, Yerrucarice, Endococci, Mycopora. Some Biatora1, which seem to occur as parasites, and as if athalline, yet are not entirely destitute of traces of a thallus (thus, for instance, gonidia are observed amongst the apothecia of Lecidea Heerii, Hepp., on the tLallus of Peltigera (Nyl., in my copy.) I may here notice also that Lecanora sophodes, var. pictavia, Wedd., p. 17, is certainly nothing new. Elsewhere I may adduce the names formerly received. 153 NOTICES OF NORTH AMERICAN FUNGI.

Archer. The appearance of a further notice of the " Ague Plant," so- called, in the preceding number but one of this Journal (No. 21, March, 1874), recalls attention to the former record of it communi- cated by Dr. Bartlett (No. 6, Dec, 1872, p. 95), and it, at the same time, reminds me of the Editor having been so good as to forward me, shortly after that occasion, some specimens of this supposed dreadful form of vegetation, bringing home to me as well the fact that, owing to many and various avocations, I had left over communicating to him the result of an examination, until, indeed, the matter had at last altogether escaped me. Meantime I perceive by the number referred to (p. 141) that its identity has since been made out, and quite correctly, as simply Botrydhnn argillacewn (Wallr.), or perhaps better, Hydrogastrum granidatmn (Linn.), Desv. Indeed, on reading over the original account of the " Ague Plant," as given from Dr. Bartlett in this Journal (p. 95, Dec, 1872), I could not but suspect that this was in fact the very plant (though he called it a " fungus") in which Dr. Salisbury believed he had discovered the " malarial essence," though I fancy there are few European observers who would not be disposed to acquit the little Hydrogastrum of being the " cause of the ague." Nevertheless I might be excused some little trepidation and mis- giving on opening the little package containing the specimen, all the way from Iowa, fearing that concentrated within might be im- ported a very unwelcome visitant. It was, no doubt, a relief, and I certainly must own to have been quite reassured, even upon a mere inspection by the unaided eye, when I did summon courage to open the little box, to see the poor little Hydrogastrum sure enough, as I had previously conjectured, showing its little withered, depressed, and collapsed rounded fronds, dotted over the surface of the dry mud. With very little compunction I placed a specimen with some water under the microscope, and found it, as indeed the majority of the examples proved to be, in the condition described by Reinsch, of which I gave an extract in this Journal (" Grevillea," No. 7, Jan., 1873, p. 107), following Mr. Parfitt's communication on this plant (1. c, p. 103), that is showing the cell, here making up the whole u plant," densely filled with rounded, rather thick- A WORD KOBE OB IHI "AGUE TLANT." 1G7 called daughter-cells, dne to the breaking up of the contents of the original individual, and destined themselres to produce young plants " in the following Bpring" (and to perpetuate the " ague " ?). Indeed, the examination with a hand lens showed certain of the examples which bad burst at the top rilled with these rounded germs (like so many little eggs in a nest). I would at once have communicated to the Editor the result of my examination, but that I had Been a reference to a paper pub- lished in the Regensburg "Flora" of 1868, purporting to contain a demonstration by Dr. Ltzigsohn that Hydrogastrum after all was not an Alga, but a Lichen, or at least that its nature was de- bateable, as one was to gather from the title: " Botrydium argillaceum, Wallr., ob Alge oder Flechte?" and I desired to know what ltzigsohn had to say upon our plant, ere sending for- ward a note of what the " Ague Plant" had turned out to be. It will be borne in mind that Itzigsohn's statements could scarcely have had any reference to the new views as to the nature of Lichens propounded by Prof. Schwendener, lately discussed at considerable length, a resume of which has appeared, and is being continued, in the " Quarterly Journal of Micros. Science." But the " Flora" was not then, and has only lately been, available in Dublin. From his paper (1. c, p. 129), we are to gather that, the Hydro- gastrum being so common in his region, Dr. ltzigsohn had long looked rather down upon it on that account, and had taken its structure for granted, by, as he mentions, merely squeezing the examples out upon a slide, in place of making sections ; still the examination he had previously given had shown him the formation of zoospores, his record of which is quoted, by Eabenhorst in his " Flora Europasa Algarum Aquae dulcis," etc. (p. 2G5), and which seems to be confirmed by Parfitt (1. c). It would seem, indeed, for so far ltzigsohn had this very plant in view, and that his fore- going statements about it are correct. But Dr. ltzigsohn desired to repeat his previous observation as to the occurrence of zoospores in Hydrogastrum, and having re- ceived some examples of what he supposed to be this plant from Dr. Ivuthe, obtained from another locality, he submitted them to examination. He now made vertical sections, and of these he gives a description, but no figures, promising a more enlarged account on a future occasion ; but I am not aware if he ever ful- filled that intention. From that description it appears indeed abundantly manifest it was now not Hydrogastrum at all which he had before him, but a true lichen, though from an outward resem- blance he at once conies to the conclusion that Hydrogastrum (Botrydium) must be no longer accounted an alga, but a lichen. A vertical section through the rounded plant itself indeed gave him an outward cortical or epidermoidal layer, composed of very delicate, distinctly organised rotundato — G-angular parenchymatous cells, 168 A WORD MORE ON THE " AGUE PLANT." followed by a "chlorogonimic " gonidial layer enclosed in a spongy indistinctly cellular mass, whilst further inwards towards the middle there occurred an irregularly interwoven fibrous layer, some of the threads of which ended blind towards the hollow centre of the " Botrydium-plant." He went further, and amongst those examples of a chestnut-brown colour he detected apothecia, with 8-spored theca?, paraphyses none, spores colourless, filled with deli- cate plasma, elongato-elliptic ; furthermore he found spermogonia, with spermatia. But these examples did not satisfy Itzigsohn, and he obtained, through friends, from Frankfort and Eichstadt, examples fully developed, which, he says, satisfied him at last that the plant passing at home with him as Botrydium was but the undeveloped state of Tballoidima vesiculare (Hoffm.) Massal ; {Lecidea vesiculare, Auct.). Still, he adds, he would reserve his final judgment until he succeeded in obtaining fresh material for the more exact examination of the common Botrydium form, though he could entertain but little doubt but that " the unde- veloped Tballoidima is perfectly identical with the plant figuring amongst phycologists as Botrydium Wallrothi." It appears, then, that Itzigsohn's statements were after all, in the present case, scarcely worth waiting for ; it cannot be doubted that, though possessing some amount of outward resemblance, these are two plants essentially distinct — it would seem pretty certain that not even a Schwendener would claim Hydrogastrum as the " gonidia-former," in any modified manner, of " Lecidea vesi- culare;" but whether Itzigsohn ever investigated the matter any further is unknown to me. On reading over the more recent description of the " Ague Plant" communicated by Dr. Bartlett to the " Chicago Society of Physicians and Surgeons" (see " Grevillea," No. 21, March, 1874, p. 142), one sees how fairly it tallies with the known characters of Hydrogastrum (see also Parfitt in " Grevillea," No. 7, January, 1873, p. 103), but it is undoubtedly surprising how he and the American observers of the Society referred to (loc. cit.) failed to perceive the identity of the organism in question, one which finds a place in so many botanical text-books, both by figure and description, as well as on lecture- diagrams, as a noteworthy example of a single-celled independent plant, and at the same time endowed with the power to become copiously ramified, so to speak, "root," "stem," and serial portion combined in one "cell" only. I venture to think it hardly less surprising to find this seemingly so passive and inert little chlorophyllaceous alga, met with, in suitable situations, all over Europe, gravely tried and found guilty, on so. slender evidence, of being the atrocious " cause of the ague." In the mud-samples so kindly forwarded by the Editor, there occurred some fragmentary examples of a plant wholly different from the foregoing — so small in quantity as to be quite invisible to the unassisted eye — but which disclosed itself amongst the debris A WORD MORE ON THE " AGUE PLANT. 1G9 taken up along with tin' II tnnn. This was a Chthono- blastns, Kiitz. (Microcoleus, Barvey), and was mosi probably the same as Ch. (Brugineus, Kiitz. Jusl when' one of these algae would be found it would not be very surprising to meel with the other. Can this latter be chargeable with being the "cause of the ague?'1 It is wholly a differenl kind of alga from Hydrogastrnm, without any point of homology or affinity therewith , except, perhaps, their common love for the damp clayey substratum afforded by the partial drying of the swamps, near which, unfortunately, from some occult cause, the "ague" is prone to hover. ON TOETULA BREVIROSTRIS. (HOOK. AND GREV.) By E. M. Holmes. While looking over some mosses, collected in the neighbourhood of Buxton by my enthusiastic bryological friend Mr. E. George, my attention was attracted by a specimen amongst them, evidently belonging to the aloid group of the To?'tulce, but which had a very short conical operculum, and upon further examination proved to have synoicous flowers, and. therefore, to belong to T. brevirodri.<. Hook, and Grev. Having reported the occurrence of this species as a British species to ]\lr. Mitten, he kindly pointed out that it had already been established as a British species, and as one new to science, in " Brewster's Edin. Journ. of Science," vol. i., p. 289, and that an excellent figure of it was given in the 2nd ed. of the " Muse. Britt.," Suppl. tab. ii. The history of this interesting little moss is a curious one. It appears to have been first collected in 1799 by Bwartz, by whom specimens were sent to Messrs. Turner and Smith under the name of T. rigida. His specimens were described by them, in 1804, asa variety of T. rigida having a short operculum. In ]V? 0? -G f ' : I M, BRITISH FUNGI OPMVICLEA- ^^^^ c Q I u m lK b aiTTSH ptjtstgi.

As the fruiting period occurs in May and June, I wish to draw the attention of bryologists more imme- diately to it. In Wilson's " Bryologia" three stations were recorded — one each in England, Scotland, and Ireland — all of which were in the neighbourhood of the sea. Since then a considerable addition has been made to the Scotch habitats. The original station of Hooker and others had been either overlooked or neglected at Bowling. At the suggestion of Mr. Roger Hennedy, Lecturer on Botany to Anderson's University, Glasgow, we visited and found the station in May, 1863. An inspection of the place led to similar localities in the West here being visited with very satis- factory results, proving that it is much more widely distributed than was at first supposed. Our stations are now as follows : — 1. — Bowling, May, 18G3, Messrs. Gait and McCartney. 2. — Whangie, New Kilpatrick, May, 18G3, Messrs. McKinlay and Shaw. 3.— Killin, Perthshire, Mr. Alex. McKinlay. 4.— Ardtun, Mull, May, 1864, Mr. Donald Black, Iona, by request of Messrs. Gait and McCartney. 5. — Skye, 1864, Mr. G. E. Hunt, Manchester; ami again in 1866 by Dr. John Shaw. 6. — Blairlogie, Stirlingshire, June, 1865, Mr. Geo. Thomson. 7. — Craigallion, Stirlingshire, March, 1868, Messrs. Thomson and Gait. 8. — Crags, near Strathblane, Campsie Hills, March, 1868, by Messrs. Thomson and Gait. This interesting moss has thus been found in the counties of Dunbarton, Argyle, Inverness, Perth, and Stirling. The attention of bryologists in other parts of the country should be specially directed to fallen basaltic rocks, and more immediately to those bared ones that are not overrun with other mosses.
