FUNGUS=FLDORA,

LACTARIUS. Fries. (figs. 2, 3, p. 301, vol. ii.)

Pireus rather rigid, fleshy, becoming more or less de-
pressed, often marked with concentric zones; gills decurrent
or adnate, unequal, often branched, rather rigid, exuding
a white or coloured milk when bruised ; stem stout, central
or very rarely excentric, its substance continuous with
that of the pileus; spores subglobose, minutely echinulate,
white, or sometimes with a very faint tinge of yellow.

Lactarius, Fries, Epicr., p. 333; Cke., Hdbk., p. 305.

The presence of white or coloured milk which flows in
drops from the pileus, and especially the gills, when
wounded, is the most important generic character, and is
the only one separating the present genus from Russula.

Every part of the fungus contains numerous anastomosing
laticiferous cells filled with a densely granular liquid latex—
or milk as termed by systematists—which escapes in drops
when the tissue is broken. The latex is, in the majority of
species, persistently white; in a few species the latex is
white at first, and gradually changes to some other colour
when exposed to the air; in a still smaller number of species,
the latex is coloured before escaping from the cells. In some
species the latex is tasteless, or mild; in others again it is
intensely acrid or peppery, even when only a very small
quantity is applied to the tongue. These peculiarities of
colour and taste of the latex are of specific importance, and
require to be noted.

I. PIPERITES.
* Tricholomoidet.

Lactarius (Piper.) scrobiculatus. Scop.

Pileus 4-8 in. across, flesh thick but not firm, whitish,
usually becoming yellowish when broken; at first convex
and umbilicate, then infundibuliform, obtuse, very viscid
when moist, with agglutinated down, yellow, becoming pale
in sunny places, usually without zones, but sometimes very
conspicuously zoned; margin incurved, fringed with shaggy
fibrils, expanding with age and becoming almost naked;
gills slightly decurrent, thin, crowded, whitish ; stem stout,
often stuffed when young, but becoming distinctly hollow,
14-24 in. long, up to 1 in. and more thick, equal, yellow,
with large roundish depressions, glabrous, rather viscid, base
downy; milk copious, at first white, becoming sulphur-
yellow when exposed to the air, very acrid; spores sub-
globose, very minutely echinulate, 7-8 p.

Lactarius scrobiculatus, Fries, Epicr., p. 334; Cke., Hdbk.,
p. 805; Cke., Dlustr., pl. 971.

Agaricus scrobiculatus, Scopoli.

In damp woods.

Distinguished by the yellow colour of pileus and stem, and
by the white milk becoming sulphur-colour when exposed
to the air. Fries says that the pileus is sometimes 12 in.
across. When growing in very wet places the flesh some-
times becomes bluish-purple when broken. Very acrid,
smell not unpleasant.

Lactarius (Piper.) intermedius. Krombh.

Pileus 4-6 in. across, fleshy, broadly infundibuliform,
viscid, smooth, ochraceous, margin involute, tomentose then
smooth; gills broad lurid-whitish, somewhat decurrent,
entire; stem 14-2 in. long, up to 1 in. thick, yellowish,
covered with spot-like depressions, solid, or sometimes
hollow; milk white then yellowish, rather acrid,

Lactarius intermedius, Krombholz, t. 58, figs. 11-13; Cke.,
Hadbk., p. 305.

In woods.

LACTARIUS. 5

Referred by Fries to L. ciliciotdes, from which it differs
more especially in the pitted stem. Differs from L. scrobicu-
Jatus in the infundibuliform pileus.

British specimens agree with Krombholz’s plant, except
that when fresh and dried they are more or less zoned, as in
L. insulsus. (B. & Br.)

Lactarius (Piper.) torminosus. Schaeff.

Pileus 3-4 in. across, even, viscid when moist, rather
fragile, obtuse, depressed, slightly zoned, margin strongly
involute for some time, shaggy with whitish fibrils, pale
flesh-colour, with often a tinge of ochre; flesh pallid; milk
white, acrid, not changing colour; gills slightly decurrent,
1-1} line broad, very thin and crowded, unequal but rarely
connected by branches, paler in colour than the pileus; stem
up to 3} in. long, }-1 in. thick, slightly adpressedly tomen-
tuse or almost glabrous, even or obsoletely scrobiculate,
dry, equal or attenuated downwards, stuffed soon hollow,
like the pileus in colour or paler; spores echinulate, 9-10 x
7-8

as torminosus, Schaeffer, t. 12.

Lactarius torminosus, Cke., Hdbk., p. 305; Cke., Dlustr.,
pl. 972.

Among grass, heather, &c.

Inodorous, acrid, pale flesh-colour; gills paler. Pileus not
unfrequently pallid ochraceous, also at times entirely white
and tomentose. (Fries.)

Allied to L. cilicioides in the strongly incurved, bearded
margin of the pileus, but known by the slightly zoned
pileus and persistently white milk.

Pileus 2-5 in. broad, smooth or nearly so, except the
involute margin, which is most copiously shaggy, depressed,
more or less zoned, of a beautiful ochre or (sometimes)
strawberry colour, at first viscid. Milk white, very acrid,
not changeable. Gills rather narrow, nearly of the same
colour as the pileus, but yellower and paler, slightly forked.
Stem 14-2 in. long, 4 in. thick, sometimes shining, obtuse,
paler than the pileus, at length hollow, clothed with a
minute depressed down. Very acrid, but the Russians
preserve it in salt, and eat it seasoned with oil and vinegar.

(Berk.)

6 _ FUNGUS-FLORA.

Lactarius (Piper.) cilicioides. Fr.

Pileus 2—4 in. across, convex then expanded and the centre
depressed, every part tomentose, viscid, not zoned, pale flesh-
colour with a fuscous tinge, margin involute, fibrillose and
woolly; flesh yellowish-white, milk acrid, white or with
a tinge of yellow eventually; gills decurrent, crowded,
branched, yellowish-white; stem firm, stuffed, usually more
or less hollow with age, equal, 2-3 in. long, 1 in. thick,
even, pruinosely-silky under a lens, pallid, not roughened
nor spotted ; spores minutely echinulate, 8 x 6-7 m.

Pileus 2—4 in. broad, depressed, margin rounded, involute,
reddish-buff sometimes glutinous, very downy, becoming
fibrillose at the margin. Gills yellowish, irregular and often
branching, apparently decurrent from the expansion of the
stipes into the substance of the pileus. Flesh yellowish-white,
darker towards the surface. Stem about 2 in. high, nearly
1 in. thick, dingy white, yellow or brown. There is no juice,
but a considerable moisture on the surface of the pileus
which seems to originate from the plant. (Grev.)

Lactarius (Russ.) lateritioroseus. Karst.

Pileus up to 34 in. broad, convex with an umbilicus, soon
depressed, often at length somewhat infundibuliform and
wavy, often unequal, zoneless or rarely slightly zoned, flesh
up to 4 lines thick, becoming very thin towards the margin,
dry, becoming broken up at the disc into minute, granule-
like squamules, scales larger towards the margin, and dis-
appearing eventually, flesh-colour or brick-red with a rosy
tinge, becoming pale; gills decurrent, rather distant, thin,
up to 3 lines broad, often furcate and connected by veins,
becoming yellowish ; stem up to 3 in. long and 2 in. thick,
stuffed, sometimes becoming hollow at the base; unequal,
incrassated at the base, curved or flexuous, rarely straight,
very slightly flocculose, colour of the pileus or paler; spores
subglobose, echinulate, uniguttulate, white, 8-9 x 6-8 yw;

hollow, scrobiculate, strigose at the base. Odour and taste
agreeable, like that of Cantharellus cibarius, but slightly

seem that this Agaric, however delicious, is not always to be
eaten with impunity. I have always found the milk acrid.

Russula, Fries, Epicr., p. 849; Cke., Hdbk., p. 319. :

A very distinct genus, closely allied to Lactarius, but dis-
tinguished by the absence of milk. As in Lactarius, the
flesh and gills of species included in the present genus are
replete with anastomosing laticiferous cells, the free ends of
which often project as cystidia between the other elements
of the hymcnium ; the dense, granular latex does not flow
from the cclls when broken, hence the absence of milk.

The flesh (due to the latex) is very acrid or hot in some
Species, mild in others, and as this character is constant
when developed under normal conditions, has been utilised
in the following. grouping of species. In a few species the
taste is mild at first, but becomes slightly acrid after re-
maining in the mouth for a short time; in others the
acridity is realised at once,!

Tho specics included in the present genus are by many
considered es passing all understanding, but I consider the
white species of Clitocybe much more difficult in that respect.

The sections proposed by Fries overlap to such an extent
as to rendcr them almost useless ; hence I have ventured on
a new distriLution of species. It may be urged against this
scheme that allied species are widely separated ; possibly so,
but I consider the primary use of a purely systematic
work is to enable the student to identify species correctly ;
and as affinities cannot possibly be indicated in serial order
on a plane surface, the loss is not great,

not becoming reddish, pileus at length infundibuliform ;
gills decurrent, thinner, crowded. Colour pallid or whitish
when young, appearing scorched and sooty-grey when old;

Fries mentions a variety which is scarcely different from
the typical form, except in the flesh becoming blue when
broken or cut. This is R. adusta coerulescens (Fr.), not yet
recorded for Britain.

R. densifolia, a species not recognised by Fries, differs
from the present species in the flesh and gills becoming
red when wounded. R. semicrema agrees in the stem turning
black, but the pileus is persistently white.

Smell none, taste mild. Pileus sometimes deep crimson-
lake at first, becoming white, especially at the disc; stem
pure white at first, then grey. Differs from R. decolorans
in the white gills.

Russula cyanoxantha. Schaeff.

Taste mild. Pileus 2-4 in. across, convex then plane, at
length depressed or infundibuliform, sometimes even, at
others rugulose or virgate, viscid, margin bent down, then
expanded, remotely and slightly striate, colour very variable,
in the typical form lilac or purplish to olive-green, disc
usually becoming pale and often yellowish; margin gene-
rally bluish or livid-purplish; flesh firm, cheesy, white,
usually reddish below the separable cuticle; gills somewhat
rounded behind, connected by veins, slightly crowded,
broad, mixed with forked and shorter ones, shining white ;
stem 2-3 in. long, up to 1 in. thick, equal, glabrous,
even, white; spongily stuffed, but‘firm, often cavernous
inside when old; spores 8-9 4; cystidia numerous, pointed.

Agaricus cyanoxantha, Schaffer.

Russula cyanoxantha, Fr., Monogr., ii. p. 194; Cke., Hdbk.,
p. 328; Cke., Illustr., pl., 1043, 1076, and 1077.

Taste mild, pleasant, and in this respect allied to R. vesca,
but in the last named the colour of the pileus is constant,
whereas in the present the colour is very variable; this,
and other points of difference are constant. When old the
pileus is sometimes pallid, greenish-white, but mixed with
purple. (Fries.)

The broad, rather distant gills with numerous projecting,
pointed cystidia, separate the present species from BR. hetero-
phylla. R. vesca differs distinctly in the reticulately rugu-
lose stem. R. furcata differs in the adnato-decurrent,
thickish gills, and in becoming slightly acrid in the mouth,
although mild at first.

64 FUNGUS-FLORA.

Cooke has figured a form (pl. 1077) having the pileus
very pale rosy lilac or almost white, disc yellowish.

Russula elephantina. Fr.

Mild. Pileus 3-4 in. across; equally fleshy but not very
thick; convex and umbilicate, glabrous, brownish-tan,
margin paler, incurved, undulating, even; gills obtusely
adnate, arcuate, rather crowded, thin, whitish, soon marked
with yellowish spots; stem 2-3 in. long, 1 in. thick, hard,
white, flesh firm, white.

Russula elephantina, Fries, Epicr., p. 350; Cke., Hdbk.,

In woods.

The absence of any tendency to turn black or red,
brownish-tan pileus, and obtusely adnate, thin, crowded
gills, separate this species from its allies. It is doubtful as
to whether the present species occurs in Britain. The only
evidence is the quotation of Bolton’s fig. 28—with a note of
interrogation—by Fries.

Habit that of R. foetens but without smell, and pileus firm
and everywhere fleshy. Stemsolid, stout, very hard, 2-3 in.
long, 1 in. thick, even, glabrous, white both outside and
inside. ileus fleshy, convex and umbilicate at first, 8 in.
broad; margin incurved, glabrous, undulate, thin, and ex-
ceeding the gills, but never striate, pellicle not separable ;
brownish-tan, paler towards the margin, not changing
colour, flesh equal, compact, thin in proportion to the size
of the fungus; gills obtusely or somewhat sinuately adnate,
arcuate, rather crowded, thin, divided behind, unequal in
front, white, reddish-yellow when bruised. Smell none.

Distinguished by the dingy yellow pileus, broad white
gills rounded behind, and the grey stem. The centre of the
pileus is sometimes rather scurfy, owing to the breaking up
of the cuticle.

R. granulosa differs in the stem not becoming grey; gills
narrowed behind, and in the numerous, slightly projecting,
pointed cystidia. RR. claroflaca differs in the chrome-yellow
pileus, and in the white gills becoming pale le.von-yellow,
tuen somewhat ochraceous,

Structure and size, also in the acrid taste, agreeing with
BR. emetica; differs distinctly in the stem being slightly
reticulately rugulose, and white then becoming greyisl ;
pellicle of pileus adnate, margin persistently even for a lung
time, gills rounded behind, becoming pallid; colour of
vileus constantly yellow, becoming pale. Inodorous like
B. emetica. (Fries.)

quite equal, minutely granular or mealy throughout,
granules snow-white at the apex, brownish below, internally
white, spongy; spores rough, subglobose, white, apiculate,
11-12 »; cystidia pointed, only slightly projecting.

Habit nearly that of RB. ochroleuca, which it also resembles
in colour, but differing in the darker and minutely granular
disc, as well as the mealy stem, which is not at all grey ;
the cuticle of the pileus is continuous from the margin for
some distance along the edge of the gills. (Cooke.)

The disc is often granular in R. ochroleuca, and the present
species is best distinguished by the granular, persistently
white stem, gills narrowed behind, and with projecting
cystidia. AR. claroflava differs in the stem turning grey and
the gills yellow. Finally, R. citrina differs in the clear |
lemon-yellow pileus and mild taste.

Distinguished by the purple pileus and stem and the
white gills. BR. drimeia somewhat resembles the present
species in general appearance, but differs in the yellow gills.

Var. purpurea; Russula purpurea, Gillet, Tab. Anal., p. 47;

with rose-colour at the middle part, and the yellowish gills.

MYCENA. Fries.

Pileus regular, thin, usually striate, more or less cam-
panulate, rarely umbilicate or depressed, conico-cylindrical at
first, with the margin straight and closely embracing the
slender, hollow, central stem ; gills adnate ur adnexed, never
truly decurrent, but often more or less sinuate behind, and
with a more or less evident decurrent tooth (= uncinate),
white, greyish, or tinged with pale reddish-pink (= flesh-
colour); spores white.

(as a subgenus of Agaricus).

MYCENA. 77

The species are as a rule small and slender, colours usually
bright and clear, but often very variable in the same species.
Several spécies are strong-scented. Most grow on wood,
branches, or twigs, although some grow in the ground and
have a long rooting base to the stem, others root among
heaps of dead leaves, and some of the minute species grow
upon dead leaves.

The edge of the gills is often very minutely fringed or
denticulate under a lens, more especially in the section
Calodontes. This is due to the presence of numerous inflated
cells or cystidia of varying length. The same structure
also occurs in other genera.

Our information is very scanty respecting nearly all the
smaller species, and as little or no information can be
derived from dried specimens, even if you are quite certain
that the correct species is at your disposal, consequently
there remains much to be done yet in the way of spore
form and size, presence or absence of cystidia, &e.

Collybia differs from the present genus in the margin of
the pileus being incurved at first,.Omphalia and Clitocybe
differ in having decurrent gills.

ANALYSIS OF THE SPECIES.

I. Insrritisz.

Minute species; stem very slender, not rooting, nor
furnished with a disc, nor downy at the base, but abruptly
piercing the substratum, dry; gills adnate, uncinate with a
decurrent tooth. Very delicate and soon flaccid after being
touched. WM. rorida agrees with the present section except
in having a very viscid stem, and is therefore placed in the
section Glutinipedes,

II. BasrrepeEs.

Stem dry, not rooting, but attached by a flattened disc
or small strigose bulb at the base. Slender, solitary, soon
Aaccid.

78 FUNGUS-FLORA.

III. GuLuTinipEDEs.

Stem juiceless, distinctly viscid or glutinous. Gills at
length with a decurrent tooth. (Some species in the follow-
ing section are viscid in wet weather, but\are distinguished
by having juice in the stem.)

IV. Lactipepes.

Gills and rooting stem dry (not viscid) but giving out
juice or milk when broken.

V. FIvirepes.

Stem slender, scarcely a line thick, never[more, flaccid,
rather tough, rooting, not viscid, juiceless, usually very
long in proportion to the size of the pileus; gills becoming |
slightly coloured, greyish, &c., margin paler, distinct. Very
slender, straight; not caespitose nor hygrophanous.

Allied to the section Rigidipedes, but smaller, stem flaccid
and with a very small cavity up the centre, and gills hardly
connected by veins, but as species with a long slender stem
occur elsewhere, all the characters must be taken into
consideration. :

VI. FRAGILIPEDES,

Stem fragile, dry, juiceless, base fibrillose, scarcely rooting,
not truly dilated at the base, not ending abruptly as in
Section I. Gills discoloured, at length slightly connected by
veins. u io :

Slender, fragile, often soft, usually with a distinct smell,
normally simple and growing on the ground, a féw of the
strong-scented ones growing on wood and tufted. :

VII. Riciprrepzs.

Stem firm, rigid, rather tough, juiceless, base more or
less strigosely rooting. Gills discoloured, grey or reddish,
at length usually connected by veins; pileus not hygro-
phanous. ;

Tough, persistent, inodorous, normally growing on wood

and much tufted, but individuals of the same species occur
solitary and on the ground.

VILL. AponrpEar.

Stem without juice and not discoid at the base; gills all
one colour, margin not darker, colour not changing. Colour
pure, bright, not brownish nor greyish..

Scattered or solitary, terrestrial.

TX. Ca LoponTes.

Stem juiceless, not expanded at the base; gills having the
edge distinctly darker than the rest, and minutely den-
ticulate, a feature that sharply separates the present section
from every other.

In WM. sanguinolenta the gills agree with those of the
present section in having a dark edge, but the stem contains
coloured juice or milk, and consequently is placed in section
Lactipedes.

3 in. long; forming dense caespitose tufts. Very similar
in general appearance to M. pullata, Berk. & Cke. (Cooke.)

Closely allied to dark forms of M. galopoda, but the latter
differs in the pileus not being so coarsely striate, and in the
nearly white gills. M. pullata differs in the absence of milk

or whitish towards the striate margin, edge quite entire;
gills narrow behind and adnexed, rather distant, broadest in
front, somewhat ventricose, white ; stem 3-5 in. long, hollow,
slightly attenuated from the base, glabrous, saffron-red, due
to the copious amount of milk of this colour which pours out
when the stem is wounded, especially at the downy rooting
portion.

On trunks, subcaespitose, or on the ground ameng fallen
branches, &c.

Very fragile, smell unpleasant. In shady places the pileus
is generally covered with a spidery silkiness. Distinguished
by the greyish-brown sulcate pileus, and by the split
portions of the stem curling outwards.

Inside decayed stumps.

Minute, ochraceous-white. Pileus 1 line broad, pale
ochraceous-white, in age almost tawny. When moist the
gills shiue through, giving a striate appearance, but not
always. (Berk.)

Distinguished among the minute species by the rather
strong, sweet scent, and rooting stem.

MM. psammicola differs in the wholly whitish-pulverulent
stem, aud in having particles sprinkled over the pileus.

Pileus 1 line broad, fleshy, for the size of the plant firm,
searcely membranaceous, obtusely conic or hemispherical,
most minutely but decidedly innato-fibrillose, pale ochra-
ceous-white, in age almost tawny, probably stained by
the wood on which it grows. When moist the gills shine
through, giving it a striate appearance, but not always.
Gills white, adnexed by reason of the growth of the pileus;
in youth they are really free. Sporules white, round. Stem
3-1 in. high, } a line thick, white, curved, rooting, the root
villous, minutely stuffed, smooth, even, under a high magni-
fying power, powdered at the top with the sporules, generally
thicker below. Odour farinaceous. Allied to A. alcalinus,
but I think distinct from all its small varieties. For it is
auch more fleshy, and seems to have no tendency to be
coloured like that species. (Berk.)

M. alcalina differs in the sticky stem. In Cooke’s figure
the gills are represented as slightly sinuate and with a
minute decurrent tooth.

Agreeing with M. alcalina in the nitrous smell; differing
in not being caespitose, the slightly striate stem; sulcate,
pruinose pileus, and emarginate gills. (Fries.)

Agaricus (Mycena) excisus, Lasch; Cke., Illustr., p. 143

On trunks. (Hothorpe.)

This is certainly not the Agaricus excisus of Lasch, neither
does it agree with any other described species.

Pileus 3 in. across, stem 4 in. high, root 2 in. long.
Solitary or subcaespitose; gills purplish, strongly cut out
behind. The fig. Bull. t. 5181, is more characteristic of the
specimens than that in Fries’ Icones, taken from smaller
and probably more superficial specimens. (B. & Br.)

Mycena cohaerens. Fr.

Pileus about 1 in. across, flesh rather thin; campanulate,
obtuse, even, glabrous, but soft to the touch and looking as
if it was rather velvety, cinnamon or tawny-umber, becom-

wards, the extreme apex often whitish, chestnut below,
hollow, very rigid, almost horny, fasciculately tufted at the
base and grown together with white down; spores 10 x

On trunks or on the ground among leaves.

Amongst pine leaves in great perfection. It has much
affinity with A. balaminus, B.; but that has the margin of
the gills purple. They have, however, the same fulvous
bristles on the surface. (B. & Br.)

In woods among leaves, also on wood. I have found it
growing in tufts on fir trunks. With the habit of Maras-
mius, but allied to M. galericulata in the gills.

Mycena excisa, Lasch.

Pileus convex, somewhat umbonate, rugulose, brownish,
gills somewhat cut out behind and almost free, ventricose,
thick, hoary; stem even almost glabrous, base rooting.

Most nearly allied to Agaricus polygrammus. Pileus.
campanulate then convex, very obtuse or umbonate, about.
1 in. across; disc slightly fleshy, pallid-fuscous or greyish-
fuscous. Gills in series of four, somewhat distant, connected
by veins, paler in colour than the pileus, very broad andi
ventricose in front, very much narrowed behind, scarcely
adnexed. Stem 1} in. long, 13-2 lines thick, grey. Tough;
almost tasteless.

Gregarious. On trunks, especially pine. Sept., Nov.

The whole of the above is a translation of Lasch’s originab
description in Linnea, l.c.

Fries’ description of what he considers to be M. excisa:
differs in some respects from the above, as admitted by him
(Jcon., p. 88), and he there also says that his fungus may be
distinct from that of Lasch.

Scotch specimens in the Berkeley herbarium are the only
ones collected in Britain so far as I know, and these pre--
sumably agreed with the Friesian idea of the species; hence,,
whether the two are identical, or if not, which species these-
specimens represent is at present uncertain.

On or near stumps, trunks, &c.

Often growing singly, and then large.

Stem short, rather thick, straight, at length compressed.
Pileus somewhat obtuse. Gills ventricose, entire or the
similarly coloured margin minutely serrulate. (Fries.

Much tougher than M. galericulata, the latter also differs
in being tufted in habit, pileus not irregularly wrinkled
but striate up to the umbo, and gills with a slight pink
tinge. M. eacisa has the pileus rugose, as in the present
species, but differs in the brownish stem and in the gills
being very much narrowed behind.

Pileus at first campanulate, then convex, sulcate up to
the umbo, cinereous, as well as the short, compressed stem,
which is glabrous above; gills distant, cinereous, uncinato-
adnate, connected by veins. (B. & Br.)

M. rugosa is most nearly allied to the present species, but
differs in growing singly, shorter stem, grey gills, and
tougher substance. A form of M. galericulata sometimes
grows on the ground among leaves.

Common on trunks, exceedingly variable, tufts often
densely crowded. Not tough and flexible, like M. rugosa.
Stems somewhat ascending, base downy, rooting, white,
tawny, bay, &c. (Hries.)

sometimes, however, much larger, campanulate or conical,
often subumbonate, at length depressed, innato-fibrillose,
striate, brownish-white, with sometimes tints of blue or
yellow. Gills rather distant, not so broadly adnate as the
last (A. alcalinus), sometimes nearly free, often pinkish.
Stem very various in length, rigid, smooth, except at the
base, which is densely strigose. Inodorous, insipid. (Berk.)

Damp places in woods.

Caespitose, tough, with a mouldy unpleasant smell. Allied
to C. confluens, but differing in habit, the stems being
brownish and not matted together at the base and not
floccose, pileus brownish-tan, and gills although free, very
close to the stem.

Fries describes two forms:—(A.) Tufted, tough, with a
mouldy smell. Stem cartilaginous, hollow, 2-3 in. long,
2-3 lines thick, or broader when compressed, flexuons,
twisted, brownish, base not rooting, at length umber,

Agaricus conigenus, Pers., Syn., p. 388; Cke., Hdbk., p. 67;
-Cke., Ilustr., pl. 130.

In pine woods, growing on cones and among pine leaves.

Usually gregarious. Known from C. tenacella and C. esculenta
by the free, closely crowded, narrow gills. C. cirrhata differs
in the adnate gills.

Gregarious. Pileus 1 in. or more broad, rather irregular,
umbonate, expanded, often depressed, sometimes quite smooth,
but occasionally more or less lanato-pubescent; sometimes
tinged with chocolate, but generally ochraceo-rufous ; pale
when dry, and then occasionally zoned, flesh woolly when
dry, firm when moist. Gills very numerous, linear, free or
only adnexed, tinged with yellow, or of the colour of the
pileus, the unequal ones very long. Spores white, globose.
Stem very various in height, 4-14 lines thick, tough, pul-
verulento-pubescent with a long very strigose rooting base,
rufous, hollow, the inside woolly. Certainly a very distinct
species from the last (A. tenacellus). I do not find any pro-

cesses on the gills. It must not be confounded with A. con-
_fluens. (Berk.)

Sclerotium not present in this species. Very variable in
size, but always small, tough, whitish, often becoming tinged.

Allied to C. conigena but known by the gills being adnate
at first. Differs from C. tuberosa in the rooting fibrillose-
base of the stem, and the absence of a sclerotium.

Collybia tuberosa. Bull.

tawny and pellucidly striate when moist, somewhat tan-
colour when dry; flesh thin, similarly coloured. Gills.
adnate, very obtuse behind, and equally attenuated to the:
front, not very much crowded, narrow, quite entire, whitish.
A pretty species, very distinct, and widely separated from
C. acervata. With the habit of Laccaria laccata, there is a
smaller variety having the stem scarcely 1 in. long, pileus.
$ in. broad, umbonate. (Fries.

Cooke has figured a fungus (Illustr., pl. 146) that on the
plate is called a variety of the present species, but in the
“Handbook” is quoted under the species which appears to
be very different from the present species. The figure in
Illustr., pl. 202, called Agaricus (Collybia) xylophilus, agrees
closely with his fig. 146, quoted above; what these are in
reality, I do not know.

In woods, pastures, &c.

Gregarious but never caespitose. OC. tenacella is allied to
the present species, but differs in the rooting base of the
stem being fibrillose, and in the snow-white gills.

The root is sometimes 6 in. long, and downy when
growing amongst leaves, either perpendicular or flexuous.

Very tough; inodorous, solitary, or sometimes in troops.
Differs from C. esculenta in the root being downy, and the
gills snow-white.

Pileus 4-1 in. broad, when young conic, then convex and
subhemispherical, at length expanded then plane, sometimes
slightly umbilicate, not striate, sub-carnose, smooth, dry,
cinereous, inclining to yellowish; often altogether abortive.
Gills free, or often adnexed, ventricose, sometimes re-
markably so, rather distant, the shorter ones truncate
behind ; in general pure white, but sometimes with a tinge
of grey; under a powerful lens covered with variously
hooked or conic papillae. Stem 2-4 in. long, scarcely 1 line
thick, flexuous, filiform, attenuated very much towards the
base and somewhat strigose, hollow, pale above, below
tawny, very minutely pubescent under a good lens; when
young beautifully downy, and then not distinctly hollow,
but with only a pale line down the centre. Taste very
pleasant. (Berk.)

Marasmius, Fries, Epicr., p. 372; Cke., Hdbk., p. 344.

A very distinct genus, but distinguished more especially
“hy biological characters, and differing from Collybia and

often narrow, very distant, and connected by prominent
~weins. Many species have a smell resembling gazlic.

Most species grow on wood, branches, or leaves.

Woods and grassy places, among fallen leaves.

Gregarious or caespitose. Taste very pungent, a feature
which separates the present from M. oreades. Not coarsely
tomentose at the base, as in M. peronatus, but only downy.

Marasmius peronatus. Fr.
Very acrid. Pileus 1-2 in. across, flesh thin, pliant;
convex then almost plane, obtuse, opaque, becoming de-
pressed here and there, or lacunose, pale rufous with a

rather thin, somewhat crowded, 1 line broad, pallid then
with a rufescent tinge; stem about 2 in. long, 13-2 lines
thick at the base, slightly thinner upwards, pale, downy
above, at the base and for some distance up densely covered
with long, spreading down (= peronate), varying in colour
from whitish to bright yellow, stuffed with fibres; spores
pip-shaped, 10 x 6-7 p.

In woods among leaves.

Amongst rotten leaves, especially oak-leaves, in woods.
July, November. Common. Pileus 1-2} in. broad, convex
or campanulate at length expanded, sometimes umbonate,
carnoso-coriaceous, sub-rufescent or yellowish, pallid when
dry, clothed with a minute matted silkiness. Gills of the
colour of the pileus with a yellowish margin, distant, rounded
behind, almost free. Stem 2-3 in. high, 2 lines thick, com-
posed of fibres, solid above and downy, hollow below and
there covered with dense yellow strigae. Taste acrid.
(Berk.)

Allied to WZ. urens, but readily recognised by the densely
woolly or peronate base of the stem.

Marasmius porreus. Fr.

Smell resembling garlic. Pileus 1-2 in. across very thin,
coriaceous, flaccid, convex then expanded, obtuse, disc even,
margin striate, opaque, dingy-yellowish, paler when dry;
gills soon becuming free, distant, rather thick, tough, about
1 line broad, at length coriaceous, yellow then pallid; stem
up to 8 in. long, 1-1} line thick, downy, reddish-brown,
apex paler, stuffed then hollow; spores subglobose, about
4 p diameter.

Marasmius porreus, Fries, Epicr., p. 874; Cke., Hdbk.,

Among fallen leaves, &c.

Often confounded with M. prasiosmus, which it resembles
in the strong garlic smell. In the present species the smell
disappears on drying, the stem is pubescent throughout its
length, the gills are yellowish, and the spores small and
subglobose ; all points of distinction from M. prasiosmus.

156 FUNGUS-FLORA.

¢membranaceous, and regularly striate. Gills nearly free,
paler than the pileus, slightly connected by veins. Stem
‘2-3 in. high, 2-3 lines thick, velvety, albido-pulverulent, as
is at once evident even in dry specimens, rufescent, tomentose
tbelow, pale above, fistulose, generally growing on the midrib
of the leaves. Odour like that of garlic, very powerful.
Specimens in Sowerby’s Herbarium gathered July 31, 1796,
still retain their garlic scent. (Berk.)

Smell weak but pleasant, stronger when dry. Pileus
rufescent, becoming pale, margin striate when moist.
Fries.) .

Root little more than a minute tomentosity, stipes firm,
solid, brittle in very young plants, tough in old ones,
furnished with a kind of fibrous bark, tearing and twisting
dongitudinally, about as thick as a goose-quill, flexuose or
-erooked, of a pale whitish brown, sometimes farinose towards
the top, from whence it is gradually attenuated downwards.
In height it is much influenced by situation, varying from
2to5in. Pileus 1-2 in. or more in breadth, hemispherical
in the young state, then obtusely conical, finally plano-
convex, and most frequently umbonate, smooth, the margin
more or less waved, and turving up with age. The substance
is leathery, the flesh white, small in quantity. Colour a
‘reddish opaque cream-colour in dry weather; but in a moist
state a watery brown, darker in the centre, and somewhat
striate at the margin. Lamellae distant, mostly four in a series,
rather thick and fleshy, free, yellowish-white, frequently

with a tinge of pink, generally lying obliquely one over
another. Fairy-rings are often observed to be formed by
this plant. (Grev.)

quite distinct from that of the stem. Gills free, pale,
distant, slightly ventricose. Stem 1-2 in. high, 2-3 lines
thick, equal, solid, very tough, composed of fibres splitting
longitudinally, the outer coat squamuloso-fibrous, base
downy, somewhat rooting and attached to the roots of the
grass. Taste and odour strong but agreeable. Though
tough, much used, as an article of food on the continent and
occasionally in this country, but too frequently very different
and poisonous fungi are gathered under the name. (Berk.)

interstices even. One of the most beautiful of Fungi, and
apparently quite distinct from M. fuscopurpureus, of which.
Fries thinks it may be a form destitute of strigae. The
pileus does not, however, rapidly change colour, as in that

On dead twigs.

Having made a drawing of this species at the time it was
found, I am able to add somewhat to Berkeley’s description.
It was growing on a bramble twig. The largest specimen
was scarce half an inch high, and the diameter of the pileus
about } of an in.; the stem hollow, sprinkled with delicate
mealy granules at the base, and about half way up; gills.
adnexed behind, narrowed in front; whitish, then flesh-
coloured, becoming brownish. (Cooke.)

An examination of Berkeley’s type specimen shows that
the spores are perfectly colourless, hence the species belongs.
to the genus Marasmius.

**® Stem slightly velvety or downy, base often somewhat
tuberculose.

Marasmius foetidus. Fr.

pruinose when dry, margin striate, rather incurved when
young; gills adnexed and joined in an imperfect ring at -
the base, distant, rather thin, reddish with a tinge of yellow; .
stem about 1 in. long, hollow, bay, 1 line or more thick,

fleshy and robust. Some species of Plewrotus with a nearly
central stem closely resemble in structure the present

externally. Clitocybe differs in the gills never being sinuate,
but gradually narrowed benind ; pileus often umbilicate, &c.
In some species the gills separate readily from the pileus,
as in Pazillus, the latter, however, is distinct in the strongly
incurved margin of the pileus, and the anastomosing gills.

ANALYSIS OF THE SPECIES.

Series A. Pileus viscid, fibrillose, scaly, or downy; not
hygrophanous; stem fibrillose from the remains of the
adnate universal veil.

I. Liwacrna.

Pellicle of pileus viscid when moist, innately fibrillose or
squamulose, but not broken up; flesh of pileus thick, firm;
margin almost naked.

* Gills not discoloured, and not becoming rufescent.
** Gills discoloured, usually spotted with reddish-brown.

TI. Genura.

Pellicle of pileus never viscid, but torn into floccose or
fibrillose squamules ; flesh of pileus soft, not hygrophanous,
margin involute and somewhat downy at first. Not to be
confounded with those species that have the pileus fibrillose
from the remains of the veil.

* Gills unchangeable, not becoming spotted with rufous
or black.

** Gills becoming tinged with rufous or greyish; edge
usually at length spotted with rufous or black.

TI. Riewa.

Pellicle of the pileus rigid, granulated or broken up into
small glabrous squamules when dry, not viscid; floccosely
scaly, not torn,into fibrils. Pileus rigid, hard when the

176 FUNGUS-FLORA.

flesh is thick, very fragile when thin, margin naked (except
in the first species.

Young specimens are often fibrillose from the remains of
the veil, and not from the torn cuticle.

* Gills white or pallid, not becoming spotted with rufous
or grey. Smell often unpleasant.

** Gills discoloured, becoming spotted with rufous’ or
grey.
IV. SERice.a.

Pileus (without a distinct pellicle) slightly silky at first;
‘soon almost glabrous, very dry; not moist, viscid, hygro-
phanous, not distinctly scaly. Pileus somewhat thin,
opaque, absorbing moisture, but the flesh resembles the gills
in colour, and is not hygrophanous. Flesh of stem entirely
fibrous, a character by which the smaller species that
resemble Collybia in habit, are distinguished.

* Gills broad, rather thick, somewhat distant, strong-
scented.

** Gills thin, crowded, narrow. Small; inodorous.

Series B. Pileus even, glabrous, not downy, nor scaly,
mot viscid, moist in rainy weather; when quite young
‘pruinose from the universal veil (but this character is not
always very conspicuous). Flesh soft, spongy or very thin,
watery and hygrophanous.

V. Gurrata.}

Pileus fleshy, soft, fragile, marked with drop-like spots,
or rivulose; stem solid.

Appearing in the spring, rarely obvious during the
autumn, caespitose or growing in troops, often in circles.

* Gills whitish.

‘** Gills discoloured, rufous or smoky grey.

VI. Sponciosa.

Pileus compact then spongy, obtuse, even, glabrous, moist
but not hygrophanous.

Firm, appearing in the autumn, in troops. Stem stout,
base usually incrassated, spongy-fibrous. Gills at length
spuriously decurrent, but sinuate, a character by which the
species are readily distinguished from Clitocybe.

* Gills not discoloured.
** Gills discoloured.

Gills readily separating from the pileus in T. cinerascens and
some others.

VII. Hycropuana.

Pileus thin, somewhat umbonate, flesh at length soft,
hygrophanous.

Stem not rooting, containing a pith, entirely fibrillose.
Pileus unequally fleshy, hence more or less umbonate, very
thin towards the margin. Colour of the pileus, both when
moist and dry, very variable in the same species. Flesh
moist, watery ; at first compact, then soft; gills thin, not
broad.

Pileus sometimes pulverulent, but this is abnormal, and
due to the persistence of the veil during dry weather.
Closely allied to the group Spongiosa, but tending towards.
Collybia rather than Clitocybe.

* Gills whitish, not spotted.
** Gills more or less violet, grey, or smoky.

Taste and smell none. Sometimes very large specimens
occur. Differs from T. sejunctum in the absence of black
streaks on the pileus, and the yellow gills.

Tricholoma sejunctum. Sow.

Swell strong, like new meal; taste bitter. Pileus about
3-4 in. across, flesh thin, fragile, white; convex then ex-
panded, gibbous, the umbo at length disappearing, viscid in
moist weather, bright yellow, virgate or streaked with
brownish, minute fibrils; gills emarginate, broad, rather
distant, pure white; stem solid, stout, ventricose, then

cartilagineo-fibrous, usually 3 in. long, 1 in. thick, somewhat
equal, naked but fibre closely striate, white. Flesh of pileus
very thin in proportion to the stout stem; convex then
plane, somewhat umbonate, unequal and wavy, 3-5 in.
broad, viscid, virgate from innate, black fibrils; for the rest
even, glabrous, usually sooty, but varies to a violet tint,
livid and pale when old; margin thin, always naked. Flesh
white, with a faint yellow tinge, fragile, gills rounded,
almost free, 3-4 lines up to 1 in. broad, distant, white at
first, then becoming yellowish or pallid-greyish. Easily
known from other species by the virgate pileus; T. jlavo-
brunneum and T. albobrunneum differ in having the gills
spotted rufescent. T. virgatum has the pileus absolutely dry.

stem being hollow, and coloured like the pileus.

Tricholoma fucatum. Fr.

Pileus 2-3 in. across, flesh thin, pallid; convex then plane,

convexo-plane, obtuse, often irregular, 2-3 in. broad, rarely
more, viscid, but readily becoming, dry and opaque, even,
glabrous, not variegated with black fibrils, but marked with
stains, lurid-yellowish or greyish-yellow, ‘disc darker. Flesh
thin, pallid, at length fragile. Margin thin, naked. Gills
deeply emarginate, 3-5 lines broad, ventricose,, somewhat
crowded, fragile, whitish, trama hyaline and coloured like
the flesh of the pileus. Inodorous. Olten confounded with
forms of T. portentosum, but clearly and easily distinguished
by paying attention to the above notes. The stem is not.
always so distinctly scaly as in the figure in “ Icones,”
tab. 24, which was drawn from a highly evolved specimen.
There are forms with the stem short and somewhat bulbous
that require to be carefully distinguished from T. portentosum.

L. portentosum is clearly distinguished from all forms of the
present species by having the pileus streaked or virgate
with innate black fibrils.

On the ground.

Fries distinguishes two forms of the present species :—
(A.) campestris ; stem stout [2 in. long, 1} in. thick], reddish,
squamuluse but not villose; pileus broad [5 in. across],
more expanded, rufous brown, indistinctly virgately squa-
mulose :—(B.) montana ; stem up to 4 in. long, quite equal,
white, apex distinctly whitish squamulose; pileus smaller

3 in. across], more convex, and altogether even. (Fries.)

Allied to 7. pessundatum by the granulated or spotted pileus,

and the flesh being reddish under the cuticle.

Tricholoma russula, Schaeff.

Pileus about 3 in. across, flesh very thick at the disc,
becoming thin towards the margin, white, tinged with rose
under the cuticle; convex then depressed, obtuse or slightly
gibbous, granulated, viscid, rosy flesh-colour, sometimes
very deep; gills slightly rounded behind then slightly

decurrent with an indistinct trace of a sinus, rather distant,
pure white, becoming slightly spotted; stem 14-2 in. long,
2 in. thick, almost equal, solid, firm, white, more or less
tinged with rose-colour, apex squamulose ; spores elliptical,
10-5 p.

Agaricus russula, Schaeffer, t. 58 ; Cke., Hdbk., p. 363; Cke.,

Among grass under trees.

Smell and taste pleasant; eaten in Austria. Flesh-colour,
sometimes spotted with yellow, as in Hygrophorus pudorinus,
with which, and Hygrophorus erubescens, it is often confused.
(Fries.)

The present differs from both the above-named species
of Hygrophorus in the granulated pileus, flesh tinged with
rose-colour under the cuticle, and in not growing in pine
woods.

Tricholoma frumentaceum. Bull.

Pileus 24-4 in. across, flesh compact, thick at the centre,
becoming gradually thinner towards the margin, white;
-convex then expanded, obtuse, glabrous, pallid, with a red
tinge, and streaked with darker lines; gills rounded behind
and slightly annexed, 3-4 lines broad, crowded, white then
reddish; stem 24-3 in. long, about 2 in. thick, equal or
slightly thickened at the base, solid, fibrillose, whitish,
more or less variegated with pale red ; spores faintly tinged
with red, elliptical, smooth, 5 x 3°5 p.

Tllustr., pl. 470.

Agaricus (Entoloma) frumentaceus, Berk., Outl., p. 144.

On the ground.

Smell like meal. There is a difference of opinion, as
shown by the following notes, as to the position of the
present species.

The plate issued in “Tllustrations” was copied from a
drawing made by Mr. Worthington Smith, from specimens
sent to him from Forres, by the Rev. Dr. Keith. Never having
been so fortunate as to see this species, we accepted the
designation attached to the drawing, and published it as an
Entoloma, under the impression that it was the Agaricus
(Entoloma) frumentaceus, B. & Br. Dr. Keith has kindly

TRICHOLOMA. 187

drawn our attention to this figure, at the same time stating
his conviction that the original specimens were those of an
undoubted Tricholoma, the pink tinge of the spores being
faint and quite of a different character to the spores in
Hyporhodii. Whatever, therefore, the plant of Berkeley and
Broome may be, to which they attach the name of A.
Ffrumentaceus, and include in the subgenus Entoloma, it cannot
be the species figured as above, since Dr. Keith must have
had ample material to judge, and no one would doubt his
ability to form an authoritative opinion. Plate 470 must,
therefore be corrected to Ag. (Tricholoma) frumentaceus,, Bull.
We may add that the majority of Continental mycologists
contend that Bulliard’s species is a Tricholoma, and both the
size and form of the spores given in our plate certainly are
more in accordance with those usually found in Tricholoma
than those of Entoloma. (Cke.)

On the ground under a hedge. Somewhat caespitose ;
pileus 34 in. across, plane, with the margin arclied and
sinuated, dry, buff, tinged with red, marked with fine
streaks, which are sometimes slightly raised, fleshy, firm,
rather brittle. Stem 2 in. high, 1 in. thick, of the same
colour as the pileus, streaked and slightly cracked, some-
times compressed, blunt at the base, with a little white
down stained with the spores. Gills broad, moderately
distant, sinuated and toothed, rounded behind, sometimcs
emarginate, adnate, cinereous, with a reddish yellow tinge;
spores elliptic, minute, ‘0002 in. long, rose-colouured. Taste
agreeable; smell farinaceous with a slight taint of amadou.
This is undoubtedly the plant of Bulliard, which is not
described by him as viscid. The spores are decidedly rose-
coloured and not white. (Berk.

Entirely pallid then white, but stem and pileus stained
with rufous, the gills at length becoming rufescent, and the
strong smell, resembling new meal, point to an undoubted
affinity with T. pessundatum. Stem solid, 3 in. lng, 4 in.
thick, equal, dry, fibrillose, whitish. Pileus truly fleshy, but
less compact than in T. pessundatum, convex then plane,
obtuse, 2-3 in. broad; viscid, dry in very dry weather, even,
glabrous, whitish or tan-colour, and variegated with rufous.
Flesh white. Gills rounded, somewhat crowded, rather
broad, white, at length spotted with rufous. (Fries.)

In woods.

The gills in “Illustrations” should have been cinereous,
but were left white by an error of the printer. (Cooke.)

Fries says that the scent is strong and nitrous; he
however did not know the fungus, and quoted Persoon.
Berkeley says the smell is slight and not at all nitrous,
whereas Bulliard does not mention the smell at all. Some-
what resembling J. terreum, but differs in the black squamules
on the stem.

Pileus 44 in. across, at first campanulate, slightly umbo-

edge at length black. Individuals occur much thicker and
larger.

Having at length found this species, I am able to state
positively that it is not the plant of Fries; the specific
name refers to the colour, not to the scent, which is very
slight, and by no means nitrous. It is not at all moist or
viscid, but has a clothy feel, being virgate and silky. The

ills are not olivaceous when rubbed. Its affinities are
rather with Ag. argyraceus than with Hygrophorus. (Berk.)

Very variable in form and size, and more especially in the
colour of the pileus; nevertheless it is easily recognised by
the form and colour of the large, broad gills, and by the
extremely fragile flesh. (Bulliard.)

pileus singularly compressed all round, minutely pitted and
wrinkled, the epidermis cracked, so as to appear tesselated.
Fries in his specific character describes it as smooth, but in
his subjoined remark implies that it is “ sericeo-adpressus.”
Hygr. cossus, Sow., with which Fries compares it in his

On the ground, especially scorched places.

A very peculiar species, entire habit remarkable, and not
to be compared with any other species of Tricholoma. From
the constantly umbilicate pileus, at first sight resembling an
Omphalia, but the stem is not at all cartilaginous, and the
gills evidently sinuate behind. Somewhat agreeing with
Tricholoma putidum in colour and stature, but in this species
the pileus is umbonate, smell strong of new meal, and
other points of difference. There are certain affinities with
certain species of Clitocybe, as C. hirneola and C. parilis,
with which the present species agrees in size, colour, and
the dingy white spores, but again, these differ widely in the
decurrent gills and many other points. (Fries.)

Appearing earlier in the season than J. gambosum, found
in April. Sometimes solitary, large; sometimes densely
caespitose and smaller. Smell and taste pleasant, weak.
Pileus regular, not turning yellowish, white when fresh,
then greyish-brown, spotted here and there. Often con-
founded with a small form of A. gambosus. (Fries.)

T. gambosum differs in the gills being attached by a
decurrent tooth; stem downy at the apex; the pileus is
usually very pale tan, but sometimes whitish.

whitish tan; margin thin, naked, involute. Flesh soft,
white, soon infested with maggots. Gills emarginate,
with a decurrent tooth, thin, crowded, whitish, colour not
changing. Among the tribe Guttata, where the species are
closely allied, and of which T. gambosum is typical, the present
species is remarkable for the flesh-coloured, unspotted pileus.

Solitary, or growing in troops. Inodorous. Cannot be
compared with any other species of Tricholoma, but re-
sembling certain caespitose species of Clitocybe, from which
it is quite distinct in the remarkably emarginate, and almost
free gills. The colour somewhat resembles that of Collybia
platyphylla, but the two are not at all allied, the last-named
differing in the thinner, virgate pileus and very broad gills.

Very luxuriant in rainy seasons, and when the weather is
very dry it is entirely absent. In dry seasons it is solitary,
whereas during rainy seasons it is , densely. caespitose.

ARMILLARIA. Fries. . jaar s

Pileus symmetrical, more or less fleshy; gills adnate or
slightly decurrent, stem central, passing continuously into
the flesh of the pileus, furnished with a ring; spores white,
elliptical, smooth.

Armillaria (as a subgen. of Agaricus), Fries, Syst. Myc., i.
p. 26; Cke., Hdbk., p. 21.

The principal points to be observed in the present genus
are, gills more or less attached to the stem, and the presence
ofaring. In a few species the ring disappears at an early
period, when the species somewhat resemble those of Tricho-
loma, but are distinguished by the gills not being sinuate ;
whereas the gills are generally sinuate, more or less, in those
species having a permanent ring. In fact but for the
presence of aring, the species of Armillaria would fall
naturally into three sections, belonging respectively to
Tricholoma, Clitocybe, and Collybia.

ANALYSIS OF THE SPECIES.

ARMILLARIA. 229

Exceedingly variable; usually densely caespitose when
growing at the base of trunks; Jarger when solitary or
almost so, among leaves on the ground. Sometimes the

stem and pileus are suffused with a yellow or orange tint, .

which at other times is entirely absent, leaving the pileus
dingy ochraceous; stem and pileus sometimes almost or
quite glabrous, especially when old.

Tufted. Pileus 1-5 in. in breadth, hemispherical in its
young state, at length nearly plane, except in the centre,
where it is usually, but not invariably, more or less umbo-
nate, slightly striated, and often somewhat uneven at the
margin; surface w unequally covered with dark or black-
pointed scales composed of bristly hairs, most numerous in
the centre; the colour of the pileus is otherwise variable,—
dull yellow, brownish-yellow, or reddish. Lamellae narrow,
whitish, at length partly reddish, rather distant, eight
in a series, adnate or even slightly decurrent. Stipes
2 to 8 in. high, robust, firm, somewhat fibrillose, generally
incrassated at the base, some shade of yellow, changing in
age to a reddish or olivaceous colour, solid, white and
spongy within. Annulus always present, spreading, large
and tumid. Spores white, copious, and when shed from
the uppermost pilei upon those below them giving them the
appearance of having been sprinkled with white powder.
There is scarcely a plant more apt to assume differeut
aspects under different conditions than the present one,
and yet, to an experienced eye, there is always a peculiarity
about it not easily expressed in words, which is sufficient to
distinguish it. (Grev.)

Undoubtedly an introduced species, and in all probability
an Australian species, as I have seen specimens from Queens-
land that agree exactly with Berkeley’s type. In Queensland
it is said to be luminous, emitting a greenish light.

LEPIOTA. Fries. (figs. 6, 7, p. 3.)

Pileus regular, usually scaly, due to the presence of the
concrete universal veil and the breaking up of the cuticle ;
gills free, often very remote from the stem and attached to
a cartilaginous collar, stem central, its substance distinct
from the flesh of the pileus; ring at filst continuous with
the cuticle of the pileus, often movable, sumetimes soon
disappearing; volva absent.

Lepiota, Fries, Syst. Myc., i. p. 19; Cke., Hdbk., p. 11 (as
a subgenus of Agaricus).

The present genus differs from Amanita and Amanitopsis im
the absence of a volva, and frum every other genus in the
Leucosporeae in the free gills.

In many species—but not in all—the flesh of the stem
is of a different texture to that of the pileus, and its apex
terminates in a socket-like depression of the flesh of the
pileus, a peculiarity clearly evident in a vertical sectiom
through pileus and stem. The remains of the universal
veil is thoroughly connate with the cuticle or the pileus, and
not in the form of removable warts or flakes as in Amanita
and Amanitopsis.

The species grow on the ground; several are met with
in hothouses, melon beds, &c., and are in all prubability
introduced species.

LEPIOTA. 233

ANALYSIS OF THE SPECIES.
A. Cuticle dry,
I. Proceri.

Ring movable, distinct from the volva.

When young the fungus is entirely enclosed in the
universal veil, which splits in a circumscissile manner, the
basal portion not distinct from the bulb, the upper portion
being concrete with the cuticle of the pileus, which is usually
scaly. Stem not peronate or sheathed with stocking-like
continuation of the volva, as in the following section; apex
of stem with a cartilaginous ring, to which the free, remote
gills are attached.

II. Ciyrro.arit.

Ring fixed, homogeneous with the universal veil that:
sheaths the stem.

Stem floccose or squamulose with the universal veil up to
the ring; cartilaginous collar at the apex close to the stem,
hence the gills are usually not so remote. Flesh soft, smell
and taste unpleasant, somewhat resembling radishes,

IIIf. ANnNuLost.

Ring superior, fixed, somewhat persistent; universal veil
adnate with the pileus.
Collar at apex of stem absent, or similar in texture to the
flesh of the stem.
IV. GRaANuLost.

Universal veil at first contiguous with pileus and stem,
and when ruptured forms the inferior ring.

Pileus granular or warted. The stem is not so distinctly
differentiated from the pileus as in the other sections.

V. Mxsomorrui.

Small, slender, stem fistulose ; pileus dry, cuticle entire.
Not granular nor torn, as in the section Clypeolarii.

B. Cuticle of pileus viscid ; not at all broken up.

Diceagaighad from species in other sections which it
somewhat resembles, in the gills being very distant from
the stem, movable ring, and glabrous stem. Cooke’s figures

On the ground.

Universal veil floccose, pale ferruginous, forming pointed
warts on the pileus which fall away readily, leaving areolate
scars on the fundamental floccose surface, as in Lycoperdon
gemmatum. (Fries.)

Distinguished from L. Friesii by the rigid, deciduous
warts of the pileus, and in the broad gills being very close
to the stem.

Lepiota Friesii. Lasch.

Pileus 3-5 in. across, flesh thick, white, not changing
colour to any appreciable extent; convex then expanded,
sometimes slightly umbonate, soft, yellowish-brown, becoming

distant from the stem, closely crowded, narrow, branched,
whitish ; stem 4-5 in. long, 4-6 lines thick at the apex, base
somewhat bulbous, coloured like the pileus, scaly, hollow,

and from L. acutesquamosa, to which it is most nearly allied,
in the branched gills and adpressed scales of the pileus.

Lepiota Badhami. Berk.
Pileus 2—4 in. across, flesh thick, and like that of the
stem becoming saffron-red when cut; campanulate then ex-
panded, obtuse, or depressed and more or less umbonate,

sooty brown, velvety or broken up into scales; gills’ free,
distant, ventricose, 2—3 lines broad, white at first; stem
2-4 in. long, 4-4 in. thick, base bulbous, slightly attenuated
upwards, whitish, silky or floccose, stuffed then hollow ;
ring firm, slightly loose; spores elliptical, 5 x 3 p.

Under yew trees, &c.

L. emplastrum agrees with the present in becoming red
when wounded, but differs in the thick, smooth cuticle
becoming broken into large patches as the pileus expands.

Piletis 2-4 in. across, at first campanulate obtuse, at length:
expanded, often depressed and umbonate, hispid, with minute,
velvety, fuliginous scales, but sometimes entirely fuliginous
without any distinct scales. Stem 2-3 in. high, }-4 in. or
more thick, attenuated above, bulbous below, white, silky or
floccoso-squamose, stuffed with cottony threads; ring firm, .
erect and deflexed, more or less movable beneath, frequently
clothed with dingy granules; gills truly remote, ventricose,
rather broad ; spores elliptic, -0003 in. long, flesh tolerably :
compact. The whole plant when wounded assumes a rich
red tint. A splendid Agaric, resembling some forms of
A. clypeolarius, but more robust. In some specimens the
surface is decidedly scaly, in others simply velvety. The.
margin often projects beyond the gills and is delicately
silky and fimbriated. The stem, though bulbous, is by no
means marginate. Smell rather disagreeable. (B. & Br.)

Lepiota emplastra. Cke. & Mass.
Pileus 2-3 in. across, flesh thick, firm, white, but like that,
of the stem becoming pink or reddish when cut; convex,
then expanded, when young covered with a thin, smooth,
dark brown cuticle that bécomes broken up into large,
_tregular, persistent patches as the pileus expands, and is
then entirely absent from the even margin, pallid and silky.

14-2 lines broad, narrowed behind, whitish ; stem about 3 in.
long,. 4 in. thick slightly thickened at the base, otherwise
equal, more or less striate, pallid, hollow; ring rather distant,

Allied to Lepiota Badhami, but distinguished by the
glabrous cuticle of the pileus and the much larger spores.

Lepiota meleagris. Sow.

Pileus 3-14 in. across, flesh thin, becoming red; convex
then expanded and almost or quite plane, cuticle broken up
into minute black scales on a pale ground, disc darker;
gills nearly or quite free, 14-2 lines broad, whitish ; stem
14-3 in. long, swollen at the base or higher up, blackish
below, pale with black squamules upwards, stuffed; ring
obsolete ; spores elliptical, 6-7 x 4 p.

Agaricus meleagris, Sowerby, Fung., t. 171; Cke., Hdbk.,
p. 13; Cke., Ilustr., pl. 26.

In hot-beds, greenhouses, &c.

It has a solid stem, and a curious, somewhat reticulated
root, in drying it becomes of a blush-red all over, except the
lower part, which retains the darker hue. (Sowerby.)

This species came up abundantly in a hot-house at Coed
Coch, Denbighshire, amongst spent ian, and is certainly a
Lepiota closely allied to Lep. clypeolarius. Two forms occur
which run into each other, the less typical of which has a
campanulate, obtuse pileus, and is of a darker tint when dry.
Pileus at first ovate or hemispherical, very obtuse, fawn-
coloured, minutely tomentose and warty, then expanded,
subcampanulate, about 2 in. across, dotted with minute
brown scales; stem at first fusiform, then nearly equal, of
the same colour, here and there tinged with yellow, most
minutely squamulose, stuffed with cottony threads; ring
soon ruptured, very fugacious; gills remote, distant rounded
behind, sometimes connected, white. The whole plant
changes in drying, or when cut, to a beautiful red. In the
variety the gills are sometimes lemon-coloured. (B. & Br.)

Lepiota biornata. B.and Br.

Pileus 1-2 in. across, flesh thick at the disc, very thin.
elsewhere, with a faint yellow tinge; convex or broadly
campanulate, silky, white, sprinkled with minute dark red
scales that are most numerous at the disc; gills free, ventri-
cose, 2 lines broad, rather crowded, white then with a pale

yellow tinge; stem 3-4 in. long, 3-5 lines thick, slightly
ventricose near the base, then attenuated and rooting,
whitish and spotted with red, reddish within, stuffed then
hollow; ring rather distant; spores elliptical, 8-9 x 6 p.

In melon and cucumber frames, &c.

The present distinct species was first described from
‘Ceylon specimens, and is probably an introduced species in
this country.

Lepiota hispida. JLasch.

Pileus 2-3 in. across, flesh thin, white, unchangeable ;
hemispherical then expanded, umbonate, tomentose or downy
at first from the remains of the universal veil, during ex-
pansion the down becomes broken up into small spreading
scaly points which eventually disappear, umber brown,
sometimes with a tawny tinge; gills free but near to the
stem, the collar of the pileus prominent, and sheathing the
stem, crowded, ventricose, simple, white ; stem about 3 in. long,
3-5 lines thick, attenuated upwards, densely squamosely-
woolly up to the superior, membranaceous, reflexed ring,
fuscous, stem tubular but fibrillosely stuffed; spores
6-7 x 4p.

In shady woods; among pine leaves, &c.

Intermediate between L. clypeolaria and L. acutesquamosa,
agreeing in size with the former, and with the latter in the
‘spinulose pileus. Smell somewhat like radishes.

Lepiota clypeolaria, Bull.

Pileus 2-3 in. across, flesh thickish, soft, white; at first
-obtusely cylindrical, even, apex tawny, surface silky and
soft but not at all broken up, then campanulately expanded,
umbo tawny, the remainder entirely broken up into very
soft, yellowish tan-coloured squamules; gills free but close
to the stem, up to 3 lines broad, soft, crowded, white or
yellowish ; stem about 3 in. high, 2-3 lines thick, soft, fragile,
equal or slightly thickened at the base, at first squarrosely
scaly from the breaking up of the yellowish veil, becoming

In woods, hothouses, &c.

Distinguished from L. cristata by the squamulose stem,
and more especially by the gills being very close to the
stem behind. Smell weak or absent.

Fries mentions the following forms:—(B). In shady pine
woods; stem covered with a white, floccose woolliness; disc
of pileus not broken up, remainder woolly, yellowish red or
becoming pale. (C). In densely shaded beech woods on
damp, rotten leaves, a slender form with a floccosely
squamulose stem; pileus white, ornamented with con-
centric brown scales. (D). Ia swampy places; pileus rosy,
squamulose.

Stem 2-34 in. high, 2 lines thick, hollow but stuffed with
cottony fibres, whitish, pale brownish or rufescent, the
whole clothed with fibrillose scales. Ring sometimes re-
maining on the stem, but more generally attached to the
margin of the pileus or evanescent. Inodorous and insipid.
Bearing some resemblance to A. procerus, but smaller and
more delicate. (Berk.)

Variable in colour, white, yellow, pink, rufous, brown, &c.
Pileus 14 in. broad, whitish, with reddish scales; stem
2-8} in. high, 2 lines thick. Inodorous and insipid
(Cooke.)

It is very desirable that the spores of this species and
allied forms should be caiefully observed, as they seem to
be the surest distinction between this species and Lep.
cristata. (B. & Br.)

Lepiota felina. Pers.

Pileus 1-14 in. across, flesh thin; ovate-campanulate then
expanded, more or less umbonate, black when quite young,

maining umbonate. The epidermis cracks into a great
number of minute reddish scales, which vanish towards the
edge, leaving that part nearly quite white, while towards
the centre the scales being smaller and more contiguous, it
is of a deeper hue. Flesh very thin, white. At its full
growth, the pileus is from # in. to 2 in. in breadth.
Lamellae moderately numerous, white, 2-4in a set, rather
narrow, their edge uneven, often splitting, free, and leaving

In fields, cucumber frames, &c.

Somewhat caespitose. Resembling L. excoriata in general
appearance, but differing in the superior, thin ring, &c. In
Cooke’s figure the pileus is slightly depressed at the disc,
and no indication of an umbo.

Lepiota cepaestipes. Sow.

Pileus 1-3 in. across, flesh thin; ovate then expanded,
disc fleshy and broadly umbonate, mealy and squamose with
evanescent plumose scales, pale sulphur-yellow or white,
dise often brownish, margin plicate; gills free, at length
distant from the stem, 1-2 lines broad, rather distant,
whitish or with a yellow tinge; stem 3-6 in. high, 14 line
thick at the apex, swollen, often very considerable at the
middle or near the base, floccose, white or pale yellow,

On tan in hothouses, melon beds, &c.

Gregarious or tufted. Probably an introduced species.

Gregarious or tufted. Whole plant white, pale sulphur-
colour or yellow. Pileus 1-3 in. broad, ovate-conical when
young, then campanulate, and finally nearly or quite plane,
darker in the centre, and more or less covered with small
scattered fibrous scales, the flesh thin, and vanishing entirely
towards the margin, which is plicate and semi-transparent ;
the substance is however tough, and bears folding between
the fingers without laceration. Lamellae numerous,'thin, in
no regular series, the extremities next the stipes broad and
rounded, and separated from it by a circular space. Stipes
3-6 in. high, straight or crooked, firm, even, smooth, narrow
at the top, but ventricose below, and then narrower again at
the very bottom, somewhat pruinose, the centre at first fitted
with delicate silky fibres, at length hollow. Annulus perfect,.
erect, persistent. Sporidia white, copious, elliptical.

In decay the pileus turns brownish, and, according to its
situation, either dries up, or becomes covered with little
globules of fluid, and gradually dissolves. (Grev.)

LEPIOTA. 247

Lepiota liemophora. B. & Br.

Entirely pale lemon-colour. Pileus about 1 in. across,
flesh very thin; coarsely grooved, up to the disc, margin
crenate, subcylindrical, then campanulate, at length plane,
gills free, very remote from the stem, distant, slightly ven-
tricose, thin, 14 line broad, interstices veined; stem 3-4 in.
high, 1-1 line thick above, becoming thickened downwards,

On soil in hot-houses, stoves, &c.

First described from Ceylon specimens, and undoubtedly
an introduced species. Distinguished from L. cepaestipes by
the glabrous pileus. Perhaps only a variety of the last-
named species.

IV. GRANULOSI.

Lepiota cinnabarina. A. & S&S.

Pileus 2-3 in. across, flesh rather thick, pallid; convex
soon expanded, obtuse or more or less gibbous, granulosely
scurfy, persistently brick red; gills free, 14-2 lines broad,
lanceolate, white; stem 14-2 in. long, 2 lines thick, base

In pine woods.

Distinguished from LZ. granulosa by the larger size and
persistently brick-red, or red-lead colour of the pileus.

Var. Terreyi, Berk. & Broome, Ann. Nat. Hist., n. 1183;
Cke., Hdbk., p. 16.

Pileus subhemispherical, bright tawny red, rough with
minute warts; stem subequal, clad with furfuraceous scales
of the same colour; ring at length torn; gills white, narrow,
remote; spores7 x 4 yp.

Pileus 1-2 in., bright tawny; scales on the stem of the
same colour, often cylindrical; gills not branched. Spores
+0002 in. long by *00015 wide (= about 7 x 4 1).

248 FUNGUS-FLORA.

This species, which appears quite distinct, approaches
L. granulosa on one side, and L. acutesquamosa on the other,
but is nearer to the latter than the former. The spores of
L. granulosa are slightly larger, those of L. acutesquamosa
are rather longer, and at the same time narrower. (B. & Br.).

Lepiota carcharias. Pers.

Smell strong, unpleasant; taste bitter. Pileus #-1} in.
across, flesh rather thin, white ; convex then almost plane,
more or less umbonate, granulose, pale flesh-colour or
yellowish-pink, sometimes whitish; gills adnexed, about
J line broad, clear white, rather crowded; stem about
14 in. long, 14-2 lines thick, slightly thickened at the base,
granulose and coloured like the pileus up to the ring, pale
and smooth above, stuffed then hollow.

Agaricus carcharias, Pers., Syn., p. 263; Cke., Hdbk.,
p. 15; Cke., Illustr., pl. 42.

On the ground, often under firs.

Distingnished from allied forms by the strong smell and
bitter taste. :

Lepiota granulosa. Batsch.

Pileus 2-1 in. across, flesh thin except at the disc, with a
reddish tinge; convex then expanded obtusely umbonate,
granulosely scurfy, rusty or brownish, sometimes nearly
white, often wrinkled, hoary and pallid when dry, margin
often fringed with fragments of the veil; gills slightly
adnexed, crowded, 14-2 lines broad, white; stem 1-24 in.
long, 2 lines thick, almost equal, floccosely squamulose and
coloured like the pileus up to the ring, smooth and pale
above, stuffed then hollow.

Agaricus granulosus, Batsch, t. 6, f. 24; Cke., Ilustr., pl. 18;
Cke., Hdbk., p. 16.

Woods, heaths, &c,

Somewhat gregarious. Distinguished from L. cinnabarina
by the adnexed gills and the pileus becoming pale. LL.
carcharia differs in the strong smell. L. amianthina is sepa-
rated by the adnate gills and yellow flesh, especially that of
the stem.

Subgregarious. ileus 4-1 in. broad, in general dull
reddish-yellow, but occasionally ferruginous, pink, ver-
milion or white. Fleshy in the centre, at first convex, or

LEPIOTA' 249

obtusely umbonate, at length often plane or depressed, some-
what wrinkled, covered with furfuraceous scales. Gills
white or yellowish white, fixed to the stem, ventricose and
nearly free in depressed specimens. Stem 1-3 in. high, 1-4
lines thick, slightly incrassated at the base, when young
solid, but in age hollow, with a core occasionally running
down from the centre of the pileus, and the base stuffed,
sometimes slightly compressed, with a subfugacious floccu-
Jose ring about the middle, above which it is slightly
fibrillose and beneath it scaly, like the pileus. In the white
variety above mentioned the pileus and stem were mealy
rather than scaly and the ring attached in fragments to the
edge of the pileus. (Berk.)

Var. rufescens, B. & Br., Ann. Nat. Hist., n. 1834;
Cke., Hdbk., p. 16; Cke., Ilustr., pl., 2134.

This curious form was found near Bristol, by Mr.
Bucknall, pure white at first, then partially turning red,
and in drying acquiring everywhere a rufous tint.

I have not seen the variety indicated above, but judging
from the figure in Cooke’s “ Illustrations,” it is about the size
of the typical form, ring obsolete or nearly so, and the stem
almost smooth throughout.

Lepiota amianthina. Scop.

Pileus 4-1 in. across, flesh thin, yellow; convex then
plane, more or less umbonate, granulosely scurfy, pale
ochraceous; gills adnate, crowded, about 14 line broad,
white then with a yellow tinge; stem 14-2 iu. iong, about
1 line thick, equal, squamulose up to the ring, smooth above,
pale, fistulose, flesh yellow.

Agaricus amianthinus, Scopoli, Carn., xi. p. 434; Cke.,
Hdbk., p. 17; Cke., Ilustr., pl. 213s.

In woods, pastures, &c.

Distinguished from allied species by the adnate gills and
yellow flesh, especially that of the stem.

Var. Broadwoodiae, B. & Br.; Cke., Hdbk., p. 17.

Pileus hemispherical, yellow, delicately tomentose, margin
incurved; stem equal, and, as well as the ring, mealy; gills
white, adnate, sometimes decurrent.

A very distinct variety, if not species. (B. & Br.)

250 FUNGUS-FLORA.

Lepiota polysticia. Berk.

Pileus about 14 in. across, flesh thick, firm, white; convex
then expanded, obtusely umbonate or quite obtuse, reddish

gills free, rounded at both ends, crowded, 2-3 lines broad,
with a yellowish tinge; stem 1-1} in. long, 3-4 lines thick
at the apex, base narrowed, scaly and coloured like the pileus
up to the imperfect ring, smooth and pale above, stuffed.

Among short grass by road sides, &e.

Pileus 14 in. broad, not at all campanulate, expanded, and
broadly and obtusely umbonate; flesh thick in the centre,
firm and tough, the epidermis broken into minute flat scales
of a rich red-brown. Gills numerous, unequal rounded

serrulate, white with a slight yellowish tinge. Stem 1 in.
high, 3 in. thick in the middle, divided into two dis-
tinct portions, the upper one silky of a pinkish hue, the
lower scaly like the pileus, but the scales browner; attenu-
ated at the base where it is furnished with many branched
fibrous roots, hollow, stuffed with fine silky filaments. Ring
furfuraceous, attached in minute portions to the edge of the
pileus. Inodorous and insipid, (Berk.)

V. MESOMORPHI.

Lepiota sistrata. Fr.

Pileus 3-14 in. across, flesh thin; campanulate then ex-
panded, obtuse or at times obtusely umbonate, whitish, disc

white, crowded, 14-2 lines broad; stem 14-2 in. long,
about 1 line thick, equal, silky-fibrillose, white, fistulose,
loosely stuffed with loose fibrils ; ring torn, fibrillose, attached
to the edge of the pileus in the form of delicate fibrils,
fugacious.

LEPIOTA. 251

Among grass, in gardens, &c.

Allied to L. seminuda and to L. mesomorpha; the former
differs in the mealy stem, the latter in the glabrous pileus
and stem and in the entire ring.

This ee species is remarkable for the filamentous ring.
(B. & B

Lepiota parvannulata, Lasch.

Pileus up to $ in. across, disc rather fleshy, remainder
almost membranaceous, campanulately convex, umbonate or
gibbous, even, at first appearing to be glabrous, but slightly
pruinose when young, white with more or less of a yellow

In pastures, &e.

In woods the specimens are often larger than the measure-
ments given above, but the pileus rarely reaches to 1 in.
across.

The only species with which L. parvannulata can be con-
founded is L. erminia, which agrees in colour, and is found
in similar places, but the latter is much larger, and differs
in the superior, torn ring, glabrous pileus, radishy smell,

Inodvrous. Very slender and delicate. J. sistrata differs
in the pileus being covered with glistening particles, and in
the stem being fibrillose downwards. L. Bucknalli differs in
the strong smell and the violet powder on the pileus and
stem.

B. Cuticle viscid, not broken up.

Lepiota medullata. Fr.

Smell resembling radishes. Every part pure white.
Pileus 14-24 in. across, flesh rather thin, watery; convex

greyish, fragments of the veil often fringing the margin;
gills free, crowded, ventricose, broadest in front, about 14-2
lines broad; stem 24-3 in. long and 3 lines thick, equal,
dry, silky-squamulose below the veil, apex striate, the thick
external cortex readily separable from an internal tube, at
length fistulose; ring incomplete, torn, usually remaining in
fragments at the margin of the pileus and scarcely evident
on the stem, rarely distinct and entire or nearly so on the
stem and almost absent from the pileus.

Agrees with L. illinita in colour, but differs in the dry
stem and distinct veil. Differs in colour from L. delicata.

Cke., Hdbk., p. 19; Cke., Ilustr., pl. 18s.

In woods, also in hothouses.

Certainly distinct from L. glioderma, although the dis-
tinctive features are not very pronounced. Differs in being
only about one-third the size; pileus not campanulate; stem
floccose, not squamose. (Fries.)

Pileus hemispherical, obtuse, rivulose, viscid, smooth,
pallid, 1 in. across; stem 4 in. high, 4 in. thick, transversely

_ punctate, squamulose, stuffed with flocci, white above; veil
floccose, slightly appendiculate; gills free, rounded behind,
approximate, pallid. The veil is really double, floccose,
covered with scaly particles. Taste like that of Polyporus
squamosus. This is clearly a stout form of Lepiota delicata, of
which we have a figure, from the author, closely corre-
sponding with our species. (B. & Br.)

Fries mentions two varieties :—pallida ; pileus yellowish
or pale rose; in woods and uncultivated places ; vaporaria ;
pileus rufescent.

Lepiota illinita. Fr.

Pileus 2-3 in. across, flesh rather thin, white, soft; ovate-
campanulate, then expanded; somewhat umbonate, viscid,
glabrous, margin slightly striate and often fimbriate, usually
clear white, sometimes tinged with ochraceous or tan-
colour; gills free, crowded, at length remote from the stem,
white; stem 2-3 in. long, 2-3 lines thick, white, equal,
glutinous, ring obsolete, stuffed then hollow.

In woods.

Entire fungus glutinous from the universal veil, which
forms an incomplete ring on the stem, when the pileus
expands; partial veil not evident. Stem stuffed when young,
soon hollow, 2-3 in. long, 2-3 lines thick, equal, fragile, not
‘at all floccose or scaly, but glutinous and slimy, but dry

above the ring. Pileus with the flesh thin, 14-8 in. across,
glabrous, viscid, soft, at length fragile, unbo with a fuscous
tinge, margin slightly striate. Gills free, at length distant
from the stem, crowded, soft, often connected by veins. ‘he
entire fungus is usually clear white, but forms occur having
the pileus clay-colour or tan-colour, margin even, fimbriute.
(Fries.)

Readily distinguished by the very imperfect ring, and the
glutinous pileus and stem. L. medullata differs in having
the stem quite dry.

Lepiota glioderma. Fr.

Pileus 1-2 in. across, flesh thin, soft, white; campanulate
then convex, broadly gibbous or obtuse, even, glabrous,
reddish-bay or yellowish-brown, viscid; gills free but close
to the stem, ventricose, broad, pure white, not spotted ; stem
about 3 in. long, 2-3 lines thick, equal, dry, soft, whitish,
covered with floccose squamules as far up as the incomplete,
torn ring, quite naked above the ring, whitish or with a
rufous tinge.

1852; Cke., Ilustr., pl. 1184; Cke., Hdbk., p. 19.

In pine woods, &c.

Readily distinguished by the dark-coloured, viscid pileus,
that does not become at all broken up at the surface, as
usual in the genus.

Analogous in many respects with L. clypeolaria, but very
distinct in the even, glabrous, viscid pileus. (Fries.)

Lepiota lenticularis. Lasch.

Pileus 3-4 in. across, flesh rather thick, soft, spongy,
white; globose when young, then campanulate and convex,
even, glabrous, naked, tan-colour with a tinge of red; gills
entirely free, but close to the stem, ventricose, broadest in
front, closely crowded, whitish ; stem 4-6 in. high, } in. and
more thick, base slightly swollen, or altogether equal, solid
but very spongy and soft, more or less squamulose or almost
glabrous; ring superior yet distant from the pileus, even,
large; stem above the ring exuding large drops of water in
damp weather which dry up and leave spots.

Pileus 3-1 in. across, flesh rather thin, white, changing to
crimson when broken; fragile, campanulate then plane,
covered with a dense, viscid mealiness, white, changing
instantly to crimson when touched, margin at length striate ;
gills free, very thin, moderately distant, somewhat ventri-
cose, about 14 line broad, white, the edge becoming crimson
when touched; stem 1-2 in. long, up to 1 line thick, slightly

Among grass, in woods, &c.

Pileus 4 in. or more broad, plane, slightly depressed in the
centre, scarcely umbonate, fleshy except at the extreme
margin, which in consequence is elegantly grooved; viscid
when moist, beautifully shining when dry; at first there
are a few broad scales, the remains of the volva, but these
soon vanish; the epidermis easily peels off. Gills free,
ventricose, broadest in front, often imbricated, white. Spores
white, round. Stem 6 in. or more high, }-1 in. thick,
attenuated upwards, obtuse at the base, where it is furnished
with a volva which is adnate for about an inch and then, in
general, closely surrounding it like a sheath, but sometimes
the margin is expanded, marked within at the base, with:
the groves of the pileus, brittle, sericeo-squamulose, scarcely
fibrillose, but splitting with ease longitudinally, hollow, or
rather stuffed with fine cottony fibres, the very base solid,
not acrid, insipid; smell scarcely any. The volva is easily
overlooked if care be not taken to dig up the very base of
the stem, as it is apt to be entangled in the grass. It occurs
of various colours; the more general one is a mouse-grey.
Bolton figures a tawny variety agreeing with A. fulvus,
Schaeff.,t. 95. Others are figured by Schaeffer of a bluish
and bay hue. Batsch has a white and Haller a green
variety. (Berk.)

viscid, glabrous, livid-bay, becoming pale, with numerous
wart-like fragments of the volva; gills free, without a de-
current line on the stem, crowded, ventricose, 3 lines broad,
clear white; stem 4-6 in. long, up to 1 in. thick at the base
and gradually attenuated upwards, pale, stuffed then hollow ;

usually distinct from the flesh of the pileus, furnished with
aring; gills free.

Amanita, Fries, Syst. Myc., i. p. 12; Cke., Hdbk., p. 6 (as
a subgenus of Agaricus).

The universal veil is quite distinct from the pileus. Most
nearly allied to Amanitopsis, which differs only in the absence
ofaring. Lepiota differs in the absence of a volva.

All the species grow on the ground.

ANALYSIS OF THE SPECIES.

* Volva splitting at the apex or circumscissile, limb free,
persistent. Pileus naked or with broad membranaceous
fragments of the pileus.

** Volva distinctly circumscissile, margin persistent, the
upper portion broken up into thick warts by the expansion
of the pileus.

*** Volva very friable, entirely broken up into wart-like
scales. Pileus with unequal mealy patches which soon
disappear, or with small, hard, polygonal warts.

**** Volva almost obsolete, flocculose, entirely dis-
appearing.

* Volva splitting or circumscissile; pileus naked or with
irregular patches. €

Smell not strong but unpleasant. Distinguished by the
ample, nearly free volva and the large ring. Fries says
that he has met with this species in late autumn having the
disc of the pileus almost black and becoming whitish towards
the margin.

Pileus 2~8 in. broad, fleshy subhemispherical, then ex-
panded or even slightly depressed, sometimes slightly umbo-
nate, irregularly scaly from the fragments of the volva
adhering to the shining surface, which is slimy when moist ;
the margin quite even and free from striae; white, straw-
coloured, olive-green with brown markings, &c. Gills
numerous, unequal, ventricose, broader in front, pure white,
subadnexed, sometimes quite free; when young covered

with a membrane which in course of expansion either falls
off or forms a deflexed ring.

Stem 3-4 in. high, half an inch thick, fibrillose with a
few adpressed scales arising from the partial ring which was
at first in contact with it, attenuated upwards, bulbous
below and there furnished with a variously lobed volva,
which is adnate with the base of the stipes, but has the
margin free and more or less expanded, in general hollow at
the apex or for some distance down, though occasionally the
inner substance is only a little more spongy than the outer,
varying much in size and colour and degree of scaliness, and
according to Fries in the manner of adherence of the volva.
When fresh it has a powerful but not disagreeable smell ;

when past maturity, its odour becomes almost insupportable.

white; ring superior, soft, lax, usually torn; volva splitting
in a regularly circumscissile manner, a portion remaining on
the pileus in the form of broad, irregular, seceding scales,
base globosely-bulbous, connate with the stem, margin acute,

Solitary. Pileus 4 in. broad, at first convex with many
flat mealy warts, which rub off with difficulty ; then expanded
and slightly depressed, glutinous when moist, when dry soft
to the touch like kid leather ; beneath the gluten are minute
fasciculato-pilose scales, but quite adpressed and innate,
reddish grey or brown, according to Fries sometimes livid,
margin sulcate and tubercled. Gills broad in front, free,
white. Spores round, pure white. Stem’ 5in. high, 4 in.
thick, stuffed, at length more or less hollow, bulbous, either
silky and even or torn into reflexed scales; ring deflexed ;

Pileus 3-6 in. broad, convex at first, at length nearly or
quite plane, striated at the margin, mostly bright red or
orange, but varying sometimes to liver-colour, yellowish,
or even whitish, warty. Warts white or yellowish, pro-
minent, pretty regularly scattered over the surface, some-
times wanting. Lamellae adnate with the stipes, very
numerous, broad, white.’ Flesh thick, white, partaking to a
small depth ofthe colour of the pileus: Stipes smooth, white,
very straight, subsolid, 4~8 in. high, nearly an inch thick,

bulbous at the base. Veil annular, white. Volva perfect
only in extremely young plants, cracking immediately into
pyramidal warts, which become less elevated, and generally
leaving a few traces upon the bulb at the base of the stem.

This most splendid chief of the agaricoid tribe really
deserves the name of imperial, applied to it by Batsch, for
the most indifferent person must be attracted by the glowing
hues of its ample pileus, its regular form, and tall pillar-like
stipes; eminently conspicuous, even at a distance, in the
shaded recesses of its native woods. In the Highlands of
Scotland it is impossible not to admire it, as seen in long
perspective between the trunks of the straight fir-trees; and
should a sunbeam penetrate through the dark and dense
foliage, and rest on its vivid surface, an effect is produced
by this chief of a humble race which might lower the pride
of many a patrician vegetable. (Grev.)

Amanita excelsa. Fr.

Pileus 4-5 in. across, flesh thick, everywhere white, un-
changeable ; soft, globose, expanding until quite plane, viscid
in damp weather, then the surface often becomes wrinkled
into wart-like projections or variously cavernous and lacu-
nose; warts or fragments of the volva friable, irregular,
angular, greyish-white, readily separating and disappearing,
colour of pileus brownish-grey, centre darker; margin even
at first, but when fully expanded and developed, evidently
striate; gills free, not striately decurrent down the stem,
ventricose, 4 in. and more broad; pure white, with many
intermediate short ones; stem at first stuffed, almost solid,
but becoming hollow, 4-6 in. long, 1 in. thick, base a de-
pressed sphere, above which the stem is attenuated upwards,
the epidermis broken up into dense, concentric scales up
to the ring or near the base only; apex striate; bulb some-
what marginate when young, but not at all separabie,
margin scaly, immersed in the ground, somewhat rooting,
having irregularly concentric grooves below the margin;:
ring superior, large, becoming free or torn; spores
8-9 x 5-6 pb.

.Pileus when young subglobose, bulb of the stem conical
below, rooting, its border sometimes incised all round, some-
times even, floccose above to the edge of the pileus; scales
of the pileus large, wart-like, with a brown disc and white
floccose border, at length falling off. Pileus when expanded

beyond the gills, Stem 6-7 in. high, 14 in. thick, firm,
solid; bulb not properly scaly; veil large; gills rounded
behind, the shorter ones denticulate at the base. Smell and
taste at first slight, at length disagreeable.

This is undoubtedly the species of Vittadini and Bulliard.
Too much stress must not be laid upon the incision of
the bulb or its scales, for neither character is constant.

Very variable, but readily distinguished from every other
species by the flesh becuming red when broken. Stem and
pileus usually becoming red when bruised. In very rainy
weather the warts of the pileus are often washed off.
A form with a short, subequal stem, and smaller, crowded,
firmly adhering warts, requires to be carefully distinguished
from A. aspera. (Fries.)

in front, narrow behind, adnexed by a fine prominent line.
Spores subelliptic. Stem stuffed at length more or less
hollow, bulbous, the bulb more or less smooth, above the
ring clothed with flat adpressed scales; below'the ring the
scales have their upper margin free and patent; ring large,
deflexed, striate. Smell strong, taste not unpleasant. Such
is the form which occurs not unfrequently in the South of
England. The discoloration of the flesh is by no means
strongly marked. Indeed I find specimens in which it is
very slight, and the change is rather to brown than red;
the stem furfuraceous below the ring, and above striate and
pulverulent; the volva thick and smooth. (Berk.)

however, more robust and differs in the squamulose stem,
and absence of smell.

HYPHOMYCETES. Corda (in part).

Saprophytes or parasites, generally superficial, or nearl
so on the matrix; rarely internal parasites in the bodies of
insects; hyphae typically septate, more or less abundantly
developed, and bearing naked conidia.

Hyphomycetes, Corda (in part), Icones Fung., i. p. 10.

Hyphomyceteae, Saccardo, Syll., vol. iv. p. 1.

The members of the present group are mostly individually
minute, and come under the designation of microscopic fungi,
and are known in popular language as “moulds.” Most
species are gregarious, and form white or coloured, cottony
or velvety patches on decaying or dead plants and animals,
although some species are true parasites. The conidia, as the
minute spores or reproductive bodies are called, are always
borne naked, on the hyphae, and are never contained in
asei, or enclosed in sporangia, as in the Phycomycetes, which
include Mucor and other genera, which are also frequently
included under the term “ moulds.”

In a few species the heads of conidia are involved in
mucus, which may, under superficial examination be mistaken
fora membrane. Again in some groups the hyphae are also
more or less viscid, and are hence more or less horny when dry.

When mature, the conidia fall away very readily, and this
is especially the case when placed in water, hence when
the general habit, mode of branching, &c., of a specimen has
been first observed under a low power of the microscope,
it is best to remove a small portion with a pair of forceps,
and place it in a drop of absolute alcohol or acetic acid on
a slide; by this means many of the conidia are retained in
their natural position; specimens treated in this way can
be stained, and afterwards mounted in Canada balsam or
glycerine jelly.

Many forms included in the present family, that were at
one time considered as distinct species, have been shown by
recent researches to be only forms in the life-cycle of more

highly developed fungi belonging to other families, more
especially to the various orders of the Ascomycetes. All
such form-species are included in the present arrangement,

The gelatinous heads of neighbouring stems unite, even
15-20 being’ thus bound together into one large common
head. The resemblance of the Gliocladium to Penicillium is.
striking, but I could not ascertain that the spores were ever
in chains in my specimens, and the abundant gelatinous
secretion of the former is a marked feature, which Mr.
Plowright informs me that he did not notice in the conidia
of the Hypomyces figured in “Grevillea.” I could not
perceive in my spores the gelatinous coat which Corda
figures; they measured 5 x 2p, and were extremely abun-
dant. The stems were thrice bi- tri-chotamous, the branchlets
being parallel and appressed. (Grove.)

much on such occasions. :

Helminthosporium, of authors (in part).

Distinguished from Helminthosporium by the shortness of
the conidia. It is very doubtful whether relative size of
conidia is sufficient to constitute a valid generic character
when all other characters are common; however, we have
accepted Saccardo’s genus, as in the present group any
character that tends to individualise a group is of service,
whether of generic value or not.

STILBEAE. 441

Fam. III. STILBEAE. Fr.

Byssoid fungi, pallid or brown. Sterile hyphae creeping,
scanty; fertile hyphae or conidiophores collected in erect,
stem-like fascicles (stromata), bearing the conidia at their
tips.

The present family differs from the two preceding in
having the fertile hyphae agglutinated into erect, stem-
like bundles, the tips of the hyphae usually becoming free
near the apex of the fascicle, and bearing the spores. ‘l'here
are two primary groups, one resembling the Mucedineae in
having the hyphae and conidia pallid; the other resembling
the Dematieae in having the hyphae and conidia dark
coloured.

Many of the so-called species are known to be the conidial
stage of species of Nectria.

The sporodochium consists of densely compacted, simple
or branched, straight or curved conidiophores which spring
from a pseudo-parenchymatous base, and become expanded
at the apex to form a more or less capitate structure. The
minute conidia form a dense waxy layer covering the
surface of the sporodochium.

The species are remarkable for being parasitic on the mem-
bers of another family of fungi, the Uredines. The general
habit is that of a Tubercularia, near to which form-genus it is

and the larger spores. The pileus is not in the least scaly.
Flesh becoming slightly tinged yellow when broken. Smell
none, taste pleasant. ae

Polystictus zonatus. Fries.

Pileus horizontal, more or less imbricated, rigid, flesh
rather thick, tuberculose and gibbous behind, convex, velvety
or sometimes almost strigose, somewhat zoned and banded
with various colours, opaque, margin whitish; pores short,
angularly rounded, obtuse, whitish, small; spores elliptical,
7-9 X 3-4 pb.

Pileus 14-3 in. across; pores about } mm. across. Some-
what resembling P. versicolor in the colour and zoning of the
pileus, but differs in being opaque and without a silky sheen,
and in being altogether thicker, and tuberculose or gibbous,
and, not depressed behind.

(To follow P. velutinus, vol. i. p. 214).

Entoloma porphyrophaeum. Fr.

Pileus 24-3} in. across, flesh rather thin, cracking; cam-
panulate, scon expanded, umbonate, sooty-brown, not hygro-
phanous, but becoming paler and mouse-colour when dry,
very opaque in every condition, even and almost glabrous ;
stem almost 3 in. long, 4-5 lines thick at the incrassated
base, solid, entirely fibrous and readily breaking up into
fibres, equally attenuated upwards, soft, naked, but un-
polished, opaque sooty purple, base with white down; gills
truncate behind, ulmost free, rather distant, 2—3 lines broad,
ventricose, distinct, greyish-white at first, then reddish-grey
from the rosy spores; spores irregularly nodulose, salmon
colour, 8-9 x 6 p.

Agaricus (Entoloma) porphyrophaeus, Fries, Monogr., i.

Among grass.

Large, soft and rather rigid, but at the same time brittle.
Margin of pileus wavy and often incised and lobed. (Fries.)

The present species has been confounded in this country
with Ag..(Ent.) jubatus, Fr., as shown by Dr. Cooke in the
following note.

ADDENDA. 495

I have just discovered that by accepting without question
the figure in Woolhope Transactions, 1868, pl. 21, as Agaricus
(Entoloma) jubatus, Fr., I have fallen into error with the
plate 317 of my illustrations. We have Ag. jubatus in this
country but it is not the same as my figure, which un-
doubtedly, as I think, represents Agaricus ( Entoloma) porphy-
rophaeus, Fr., on account of the solid stem, purplish in colour,
attenuated upwards, pileus neither villose nor squamose,
and gills truncate behind, not to mention their colour.

It must be added that the dimensions of the spores given
by Saccardo, evidently are on the authority of Britzelmeyer,
whose figure cannot be the species of Fries, and hence there
is no authority for spore measurements in Ag. porphyrophaeus.
Moreover the delusion was increased by the description given
in the Woolhope Transactions, which is not the descriptiou
given by Fries, and does not represent his Ag. jubatus. I
believe that it is less derogatory in me to confess this error
than to have made it. (M. C. Cooke.)
