Venti- lation is effected by a slide in the door, and a wooden trunk up through the arch and roof, with a slide in it also. We do not exactly see the motive of Mr. Patrick, whom we have long known and esteemed as one of the best gardeners in England, in adopting the span roof over this house, as, from its situation behind the garden wall, a lean-to roof would have been cheaper and carried off the rain-water better. It is rather a novel, but still a good plan, to have the inner roof constructed of a brick arch, as it will of coui'se save the outer one from decay, to Avhich all mushroom-house roofs are liable more than any other kind of garden building. This house struck us at first sight as very complete, excepting in breadth. We should increase it to 9 feet — that is, 3 feet for the breadth of the beds on each side, and the same for the footpath, which at present is incon- veniently narrow. ^^ The Russian mushroom-house (fig. 10) is thus de- scribed by Mr. Oldacre, in the Horticultural Society's Transactions, vol. ii. first scries. *' The outside walls should be 8^ feet high for four heights of beds, and 6^ for three heights, and 10 feet wide inside the walls. This is the most convenient width, as it admits of shelves 3J feet wide on each side, and affords a space through the middle 10 MUSHROOM CULTURE. of the house 3 feet wide,, for a double flue and a walk upon it/-' Hot-water pipes were not in use when this house was erected. "The walls should be 9 inches thickj and the length of the house as may be judged necessary. When the outside of the house is built, place a ceiling over it (as high as the top of the walls) of Fig. 10. Eussian mushroom-house. boards 1 inch thick, and plaster it on the upper side with road sand well wrought together, 1 inch thick, (this will be found superior to lime), leaving square trunks, /, in the ceiling 9 inches in width, up the THE MUSHROOM-HOUSE. 11 middle of the house^ at 6 feet distanee from each other, with slides^ s, under them, to admit and take off air when necessary. This being done, erect two single- brick walls, V Vj each five bricks high, at the distance of S^ feet from the outside walls, to hold up the sides of the lower beds_, a «, and form one side of the air- flue, tutu, leaving 3 feet up the middle, t x t, oi the house for the floor. Upon these walls, v v, lay planks, / w, 4J inches wide and 3 inches thick, in which to mortise the standards, t k, which support the shelves. These standards should be 3J inches square, and placed 4 feet 6 inches asunder^ and fastened at the top to the ceiling joists. When the standards are set up, fix the cross- bearers, I n i n, that are to support the shelves, o o, mortising one end of each into the standards, w, the other into the walls, i. The first set of bearers should be 2 feet from the floor, and each succeeding set 2 feet from that below it.

Fasten this board on the outside standards, that the width of the beds may not be diminished. The shelves being completed, the next thing to be done is the construction of the flue {p in section), which should commence at the end of the house next to the door, run 12 MUSHROOM CULTURE. parallel to the shelves all the length of the house^ and return back to the fireplace, where the chimney should be built ; the sides of the flue inside to be of the height of four bricks laid flatways, and 6 inches wide, which will make the width of the flues 15 inches from out- side to outside, and leave a cavity, t u, on each side betwixt the flue and the walls that are under the shelves, and one, x y, up the middle, betwixt the flues, 2 inches wide, to admit the heat into the house from the sides of the flues /^ The introduction of this form of house by Mr. Oldacre has led to much improvement in our mush- room culture. The first house of this kind erected in England, was built at Shipley, near Derby, in the garden of E. M. Mundy, Esq., by the father of Mr. W. P. Ayres, whose name will be found frequently mentioned in this work. There brick arches were formed for the shelves, and though built more than half a century ago, the house is still in good condition. Although slate is generally used for the shelves, the adoption of cast-iron gratings for this purpose is well worth a trial, as by this means we may be enabled to cut mushrooms from the under as well as the upper side of the bed. 13 CHAPTER IT. THE PREPARATION OF THE MATERIALS^ ETC. Before we deal witli the various ways of growing the mushroom, we will speak of the preparation of the material. As stable manure not only furnishes the nutriment, but forms the very soil in which muslirooms are produced artificially, and also supplies the heat which enables us to grow them to perfection at all seasons, by far the most important point connected with their culture is the management of this. It is very simple, but frequently, even by excellent gardeners, con- sidered to require much more trouble and nicety than is really necessary. For example, it is quite common in good gardens to see the droppings collected carefully in some shed, or in the mushroom-house, and turned over almost as tenderly and carefully as the contents of the fruit-room. Good mushrooms are well worth this trouble ; but, as it is quite unnecessary, it should not be done except in special cases. To show the diversity of opinion among excellent mushroom-growers as to the preparation of the manure, 14 MUSHROOM CULTURE. I will quote a few of our most trustworthy authorities on the subject. Mr. W. Early, in " How to Grow Mushrooms/^ lays great stress on the importance of gathering the droppings in a dry state. " Every advan- tage should be taken of opportunities of securing and placing them in any open shed_, or other similar position, where they can be effectually sheltered from rains. In such a place, whilst the process of col- lecting is going on, every portion should be spread loosely over the floor, in moderate sized ridges, or in any other manner that will allow the air to get amongst it to assist in drying. It should also be tossed over or tm'ned, and lightened up daily for the same purpose, until a sufficiency is gathered together for immediate use.^'* This may be taken as a sample of the practice very extensively followed in this country. Happily, we have excellent mushroom growers who succeed without all this trouble, as the following remarks of Mr. J. Barnes will show : — '' For the last thirty years I have made my beds entirely on the floor in sheds, wheeling in the stable dung as it is brought fresh from the stable^ adding a fourth, or a little more than a fourth, of good friable loam, mixing both well together, pressing firmly down, and letting it remain about a week or so untouched. At the end of that time we turn it over, and if we consider it in too strong a state of fermenta- tion we add a little more soil, and then tread down THE PREPARATION OP THE MATERIALS. 15 firmly. Very soon the bed is ready to be spawned, and encased in a couple of inches of soil; and in this way "we get the finest crops of mushrooms, the beds remaining a long time in bearing. After the beds have been some time, say from six to twelve weeks, in bearing, and begin to get dry, and cease to bear well, vre water them thoroughly with very clear liquid manure, made from sheep or deer or cow manure, which seems to start them again into bearing, and then we manage to keep some of the beds in bearing for many months at a time.^^ In the Field, Dec. 22, 1868, I stated that the manure for the mushroom-beds in the Royal Gardens, Frogmore, was not prepared in any elaborate way, but simply taken from a great heap fermenting in the yard, any parts of it that had become white from heat being moistened with water, and the whole being mixed with about a fourth part of loam. !Mr. Cuthill, an authority on mushroom culture, tells us how the London market gardeners manage with their manure. As the material is brought home from the London stables, the short part is taken out of it, and the long litter is kept for the purpose of cover- ing, as well as for forming the interior of ridges ; for all mushroom -beds out of doors are made into ridges. The manure is not allowed to heat before it is put into the beds, if that can be prevented ; for previously heated material does not produce such fine mushrooms. The fresher the horse-dung is, the longer the crop will last ; 16 MUSHROOM CULTURE. and every gardener who makes up beds with unhealed droppings knows how superior they are to fermented manure. In his own practice Mr. C. depended a good deal on heavy tramping to " keep down fermentation^'' when drop- pings were used in a fresh state. The French^ who are great mushroom growers^ allow the manure to heat first, but treat it very simply. They prepare it in the open air, first removing any pieces of wood or other extraneous matter that may have been mixed with it, and then place it long and short in beds two feet thick, or a little more, pressing it with the fork. When this is done, the mass or bed is well stamped, then thoroughly watered, and finally again pressed down by stamping. It is left in this state for eight or ten days, by which time it has begun to ferment, after which the bed ought to be well turned over and re-made on the same place, care being taken to place the manure that was near the sides at first towards the centre in the turning and re-making. The mass is now left for another ten days or so, at the end of which time the manure is about in proper condi- tion for making the beds, either in the open air or in the caves. Sometimes it receives three turnings over, especially when the manure is long, and it occupies altogether about six weeks in preparation. As the wide heaps are turned over by the men, a water-cart remains alongside, and any portions of the mass that are THE PREPARATION OF THE MATERIALS. 17 dry and white from heat are moistened with water from a rose watering pot. This preparation shortens and mollifies the longer material considerably^ mixes the mass well^ and it is transferred to the caves in a slightly de- composed, well mixed, and moist, but not wet, condition. The French do not actually hammer or desperately tramp down the beds, as nearly all our writers on mushroom culture recommend, but press it pretty firmly ; and I have seen as good crops on their light spongy beds as ever I have on those so firmly tramped down. I might give other striking instances of the diversity of opinion on this subject, but it is needless to multiply them. My conclusions respecting the preparationof the manure for mushrooms are as follows : — 1 . That very careful prepa- ration and frequent turning over of the manure undercover are not necessary to success, and that it is quite needless to prepare the manure under cover, except when it is gathered in a very small quantity, so that a heavy rain or snow Avould saturate it. AVhere, however, the culture is pursued on a very small scale, and, it may be, only one bed made, it is best to keep it in a covered shed. 2. That carefully picked droppings are not essential, though they may be more convenient. Excellent crops are gathered from beds made with ordinary stable manure, droppings and long materials mixed as they come ; but when the manure is used as it comes from the stable, it should be allowed to ferment before being used. 3. That c 18 MUSHROOM CULTURE. the best vraj of preparing manure for the general eulture of mushrooms indoors^ is to gather it in some firm spot, and allow it to lose its fierce heat. As it is usually- gathered in an irregular "way, precise directions as to turning over cannot well be given ; but I am convinced that one turning will sufiice when it has arrived at a strong- heat, and then it should be thrown together for a week or so, when, in being disturbed and removed to make the bed or beds, its strong heat will be sufficiently subdued. Where large quantities of stable manure are in a fer- menting state, there should be little difficulty in selecting material to form a bed at any time. Should it have spent its heat overmuch, it would be easy to revive it with some fresh droppings. 4. That stable manure may be used when fresh, but it should be always mixed with more than a fourth of good loamy soil. If this be kept under cover, or stacked so that it may be had in a rather dry condi- tion, so much the better, especially if the fresh manure, &c., should be over moist. Beds thus made are most suited for cool sheds and the open gardens. 5. That a portion, say nearly one -fifth to one-third, of good and rather dry loam may always be advantageously mixed with the stable manure ; the fresher the materials, the more loam should be used. In all cases it helps to solidify the bed, and it is probable that the addition of the loam adds to the fertility and duration of the bed. 6. That a thickness of from one foot to fifteen inches for the beds THE PREPARATION OF THE MATERIALS. 19 in an artificially heated house is quite sufficient. Eighteen inches will not be too much for beds made in sheds, though I have seen excellent crops on beds only a foot thick, in common sheds Tvith leaky sides. All beds made indoors should be flat and flrmly beaten down, though the absence of firmness is not, as some think, sufficient to account for want of success. I will now quote a few words from Mr. Ayres on. other materials for forming mushroom-beds than stable manure. He has given this, like almost every important subject in the range of horticulture, some attention. First among these may be mentioned sawdust which has been used for bedding horses or for riding-school tracks. Such a substance, thoroughly impregnated with urine and mixed with horse-droppings, forms an excellent material for mushroom-beds, especially if mixed with one- fourth of good fibrous loam. Such materials mixed and fermented together, and thrown into a bed a foot or eighteen inches in thickness, according to the temperature of the shed in which the bed is made, will be found to form capital material for growing this esculent, especially as it retains the heat for a long time. The worst of it is that the material is almost valueless after it has served the first purpose ; and used as dung upon light land is rather injurious than otherwise. Then you may use leaves and loam, in the proportion of one part of the latter, in a turfy state, to four or five of fermenting leaves. c 2 20 MUSHROOM CULTURE. These may be recently gathered from the trees^ and should be allowed to attain a brisk heat before the loam is added,, and then^, after sweating for a week or ten days, may be turned^ mixing the materials intimately together, and then the mass may be formed into a bed. A mushroom^ bed of this kind should not be less than fifteen inches in thickness when thoroughly consolidated ; and when so managed it will grow mushrooms just as well as dung. The sweepings of our streets and cattle markets, especially those parts that are paved and much frequented by horses — as, for example, cabstands, &c. — if collected when dry, and fermented a little, yield capital material for beds. Here from the cattle market we have the dung of horses, sheep, and cows mixed together in a finely divided state, the heating of which is gentle and regular. Material of this kind procured on dry days, thrown together to ferment once or twice, and then made into well-consoli- dated beds, will produce mushrooms of the finest quality, and continue in bearing a very long time. It is of the first importance that this material be collected in a dry state, as of course the slush of the streets would not do at all. Equal proportions of street sweepings and fresh leaves, properly fermented and mixed with loam, would perhaps make as good material for growing mushrooms as need be obtained. Of course the sweepings from those parts of the town most frequented by horses will be the best for the purpose I am writing about. THE PREPARATION OF THE MATERIALS. 21 The idea of mushrooms ceasing to be prolific from the exhaustion of the active manure in the bed_, I have mooted before. Lately several experiments have been tried which convince me that by taking three portions of recently-gathered leaves to one of turfy loam, and working them well together until the mass attains the desired temperature, sprinkling it, as the work of turning proceeds, with liquid direct from the stables, and forming this into a bed treated in the usual manner, it will give just as good mushrooms as the best horse manure in the world. It is the ammonia that is wanted for this crop, with a gentle heat. Secure these two things, and, with ordinary care, success is certain. Eefore making the beds, while the material is in pre- paration, all particles of old wood, twigs, &c., that are found in the manure should be removed, as indeed should any extraneous matters likely to prove offensive or useless. The best time for making mushroom-beds, where they are not regularly made in succession throughout the autumn and winter months, as they ought to be where there is abundance of material and a good mushroom- house, is in August and September, as in the early autumn months the natural heat is sufficient to cause the spawn to germinate freely, and, beds made then ought to bear freely before and up to Christmas, and during autumn. When making the bed, the chief object to bear iu 22 MUSHROOM CULTURE. mind is the equal placing of the material. It should be well mixed and regularly and firmly placed so that the whole may be of a similar texture. Some heavily tramp and pound their beds to secure firmness; moderately done this is beneficial ; thoroughly equable pressure with the fork^ when the fork can be used^, will with the pressure of firm earthing be sufficient ; when beds are made on elevated benches in boxes^ and in all positions where but a slight body of material is used, and where firmness can- not result from the general pressure of the mass_, some kind of pressure with a wooden mallet or the like must be employed. The beds once made,, we next arrive at the spawning, and will first inquire^ What is spawn ? 23 CHAPTER III. MUSHROOM-SPAWN. The first thing we have to determine is, What is spawn ? Generally^ the spawn, or what in scientific language is called the myceUunij is supposed to be analogous to seed, while it really is what may be termed the vegetation of the plant, or something analogous to roots, stems, and leaves of ordinary plants, the visible part or stem, head and gills, of the mushroom being, in fact, the fructifica- tion, though in such an apparent preponderance to the other parts. A knowledge of the anatomy and life- history of the mushroom is not necessary to the cul- tivator, and is not familiar even to those who make of mushrooms a study. We know that the gills arc simply surfaces on which germs or spores are produced. The membrane that covers the spore plates of a single mushroom would cover a large space if spread out, and the spores are counted by myriads. AVe can see them clearly enough under the microscope — can sec in what manner they are borne on and fixed to the gills ; but of the history of their lives, from the time they fall from the 24 MUSHROOM CULTURE. surfaces on which they were bom, till the ^' youDg mush- room^^ or inflorescence is vigorously pushing up from the mass of delicate vegetation which they have given rise to in earth or decaying manure, we know nothing. How^ever, the preparation of the spawn, and the sub- sequent management of it in the mushroom-bed, are the matters which really concern us. How is spawn obtained in the first instance ? It is found in a natural state in half-decomposed manure- heaps, in places where horse-droppings have accumulated and been kept dry, in riding-schools, sheds to which horses have long had access, in ''mill tracks^"* under cover, in pastures, in partially decayed hotbeds, &c., and rarely or never in very moist or saturated materials. This spawn, sometimes termed "' natural'"' in this country, and called by the French " virgin spawn,^^ is the best that can be obtained, and should be used in preference wherever it can be found. To use it, all that has to be done is to divide the material permeated by the white spawn into pieces a fcAV inches square, and say an inch or more thick. They will of course break up irregularly, but all should be used, whether of the size of a bean, or nearly that of the open hand. Then they are inserted into the surface of the mushroom-beds in the ordinary way. In nearly every country place, and in numerous suburban ones, in fact, in most places where horses are kept, opportunities of finding this spawn occur. Its MUSHROOM-SPAWN. 25 white, filamentous, and downy threads have the odour of mushrooms,, and the spawn is, therefore, very easily re- cognised. It should be generally known that it need not be used when found, but may be dried, and kept for use in a dry place for years, and has been known to keep as long as fourteen years. It must not be supposed that it is only the hard bricks described further on that keep thus. The French spawn is in much looser and lighter material than that in which we usually find mycelium in a natural state, and it keeps quite as long as ours. To presence spawn found in a natural state, nothing more is required than to take up carefully the parts of the manure in which it is found, not breaking them up more than may be necessary, and placing both large and small pieces loosely in rough shallow hampers. These should be placed in some dry airy loft or shed till thoroughly dry, and afterwards kept in some perfectly dry place, packed in rough boxes till wanted for use. But inasmuch as in this country, at present, but little mushroom-spawn is required in any one place, the rule is to obtain artificial spawn in the form of hard bricks. This spawn is made from horse-droppings and some cow- dung and road scrapings beaten up into a mortar-like con- sistency in a shed, and then formed into bricks, slightly differing in shape with difterent makers, but usually thinner and wider than common building bricks. Various recipes are given for mixing the materials for the bricks, 26 MUSHROOM CULTURE. and among tliem the following are about the best : — 1. Horse-droppings the chief part, cowdung a fourth, and the remainder loam. 2. Fresh horse-droppings mixed with short litter the greater part, cowdung one third, and the rest mould or loam. 3. Horsedung, cowdung, and loam in equal parts. These bricks are placed in some dry, airy place, and when half dry, a little bit of spawn about as big as a hazel nut, is placed in the centre of each; or sometimes, when the bricks are as Fig. 11. Brick mushroom-spawn. wide as long, a particle is put near each corner, just in- serted below the surface, and plastered over with the composition of which the bricks are made. When the bricks are nearly dry, they are placed on a hotbed about a foot thick, in a shed or dry place. On this the bricks are piled, or placed rather openly and loosely, and covered over with litter, so that the heat may circulate equably amongst them. The temperature should not rise more than a degree or two above 60 degrees; if it does, it may easily be modified by reducing or removing MUSHROOM-SPAWN. 37 the covering of litter. The makers frequently examine the bricks during the process^ and -when the spawn has been found to spread throughout a brick like a fine Tvhite mould_, it is removed^ and allowed to dry for future use in a dark^ dry place. If allowed to go further than the fine white mould stage^ and form threads and tubercles in the bricks,, it has then attained to a higher degree of development than is consistent with preserving its vegetative powers, and therefore it should be removed from the bed in the fine mould stage. This is the kind of mushroom spawn mostly in use in our gardens, and it is usually very hard in textui'c. There is a kind of spawn usedinsome gardens called mill- track mushroom-spawn, which is made in a more simple Fig. 12. Mill-track mushroom-spawn. manner than the preceding. It would seem to be simply spawn that has spread through the thoroughly amalga- mated droppings of a mill-track. The material is rather 28 MUSHROOM CULTURE. soft and free in texture^ is usually sold in large and some- what irregular lumps_, and is much used by some cultivators. Finally, we have the French mushroom- spawn, which differs from our own in not being in bricks or solid lumps, but in rather light masses of scarcely half decomposed, comparatively loose and dry litter. This spawn is ob- tained b}^ preparing a little bed as if for mushrooms in the ordinary way, and spawning it with morsels of virgin spawn, if that is obtainable ; and then Avhen the spawn Fig. 13. Parisian mushroom-spawn. has spread through it, the bed is broken up and used for spawning beds in the caves, or dried and pre- served for sale. It is sold in small boxes, and is fit for insertion when pulled in rather thin pieces, about half the size of the open liand ; but in separating it, it divides into many pieces, of all sizes, every particle of which should be used. The small particles should be strewn broadcast over the bed after the larger pieces have been MUSHROOM-SPAWN. 29 inserted. This applies to the other kinds. In conse- quence of the open porous nature of the French mushroom- spawn_, it is likely to be immediately affected by the heat and moisture of the genially warm manure forming the mushroom-bed, and on that account alone presents some advantages. It has recently been introduced for the first time, and probably will soon be tested by many growers. Spawn, in the common sense of the word, may be dispensed with by well amalgamating manure, loam, and old mushroom-beds, or leaf-mould containing traces of spawn, and these formed into beds about a foot thick in the mushroom-house, and covered with earth, produce without any further spawning ; but the plan is not so simple or advantageous as that more commonly pursued. There is no necessity for purchasing artificial spawn at all where mushrooms are regularly grown. Nor is there in any case except at the commencement, or to guard against one's own spawn proving bad. To secure good spawn, we have only to do as the French growers do: take a portion of a bed where it is thoroughly permeated by the spawn and before it begins to bear, and preserve it for future use. Of the efficacy of this sort of spawn, if any proof were needed in addition to the fine crops tlic Parisian growers gather, it will be found in the following statement from Mr. Ayres : — 30 MUSHROOM CULTURE. ^^ A short time back^ attention was directed to the supe- rior quality of French mushroom-spawn^ and as a natural consequence several London seedsmen imported it for sale. Some months back I obtained possession of a stable, and_, wishing to grow mushrooms in it, procured a few tons of horse manure, just as it came from the dung-pit of the hotel stables. It was very wet, and con- sequently when thrown together it heated violently. However, by frequent turning for a week or ten days this tendency was reduced, and then five beds were formed of it, adding one-fourth of perfectly dry soil from a cucumber-house. I say perfectly dry, because the soil had lain in the house for fifteen or eighteen months without receiving a drop of water, and therefore may almost be considered as thoroughly dry. Intimately mixed with the fermenting dung, it had the tendenc}^ that I desired — viz., subdued the excessive moisture, and, after the bed had been made up a week, brought it to the temperature necessary to receive the spawn. ^' Having great faith in the good qualities of fresh loam from an old pasture for the production of mushrooms of superior quality, I had a quantity dried and warmed. I had a coat of this three inches thick laid over each bed, and then forked carefully in, taking care to mix the soil and dung as intimately as possible. Re-formed and left for a few days the beds attained the necessary warmth ; then they were made quite firm, and were ready for spawning. MUSHROOM-SPAWN. 31 ''For this purpose I had procured two boxes of the French spawn from Messrs. Barr and Sugden, of Covent Garden. It was lights loose, flaky^ chaffy stuff, and so dry that I had some fear whether its vegetating power had not been dried out of it. But the spawn had been bought for experiment, and therefore the experiment must be carried out. " Baking about two inches of the material from the surface of each bed, pieces of the flaky spawn were laid down, at about ten inches or a foot apart, all over the beds ; the fine portions of the spawn were then scattered over the beds, patted down firmly with the back of a spade, and then the surface material was returned, and the whole made as firm as possible. In passing, it may not be out of place to remark that spawning in this manner must be guided, or rather governed, by the state of the material of the bed. If it is not sufficiently cooled, it will be safer to make holes in the usual manner for the spawn ; but if in a fit state, then I think the broadcast spawning and earthing, as before described, is the best plan. The disturbed portion of the beds having regained its heat, and there being no fear of its over- heating, the beds were immediately earthed two inches thick with fresh loam, beaten quite firm, and then covered with a thin layer of dry hay. " Not liking to entrust my chance of mushrooms en- tirely to the new material, the French spawn, two beds 32 MUSHROOM CULTURE. were spawned at the same time and in the same manner with native spawn. Owing to the large size of the stable, and the nnnsnally cold, piercing weather at the end of the year (1869), the beds lost so much heat that I had some misgivings whether they would not prove a failure ; but finding, subsequently, that the spawn was working, I gave each bed (the surface being rather dry) a good syringing with water at the temperature of 80 deg., covered it with clean dry mats, and then returned the hay. The beds are now a sheet of the '^pearl of the fields,^ some of the patches as large as a cheese-plate, and the whole in most promising condition — so promising that, with proper attention, I have no doubt they will yield a good supply of mushrooms for many months To secure this continuous bearing, farmyard manure-water and salt, at proper times, should not be spared ; while, as soon as the flush of the first crop is over, the beds may receive a thorough soaking of manure-water at a temperature of not less than 80 deg., be re-earthed with fresh soil, and covered down with mats and hay. In this manner we always get a second crop little in- ferior to the first one, and sometimes much superior/' 33 CHAPTER IV. SPAWNING AND AFTER-TREATMENT. Heat and Protection. The temperature of the material of the beds should never, at spa^\Tiing time, exceed 80 degrees Fahr. — about 70 is the most suitable regular temperature ; and that of the mushroom-houso should range between 50 and 60 degrees — not lower than 50. Assuming the materials to have been turned once after having heated, and again disturbed previous to being made into beds, they ought to be in a condition for spawning from ten to twelve days after being put together. It need hardly be said that this regularity of temperature can only be secured in properly-formed mushroom-houses. "Where mush- rooms are grown in these, T\dth double ceilings and close- fitting shutters and doors, almost impervious to external influences, and where fresh beds are made from time to time, little or no artificial heat from jnpes is required, though it is as well to have some at command in the case of unusually severe weather, or a break in the suc- cession of beds, which would cause a deficiency of heat from fermenting materials. A covering of hay or dry D 34 MUSHROOM CULTURE. litter is necessary for beds formed in the open air^ and also for beds made in cool^ lialf-open sheds ; bnt not for those in regularly heated mnshroom-houses or caves^ in which there is a still_, steady temperature. It should be about a foot thick, and should be immediately removed •when it becomes wet or mouldy. This covering should be applied whenever the temperature of the bed begins to fall. It should not be used in any case where the tem- perature will permit of dispensing with it_, as it is trouble- some, and sometimes encourages insects. The heat of a bed may be reduced by opening holes six or eight inches deep with a thick pointed dibber, here and there, but it is only in exceptional cases that this is advisable, and it is desirable to husband all the ammonia and heat of the bed. The earthing over and firming of a bed has a ten- dency to subdue the heat in it. Where large sloping beds, say three feet deep at back, are made against the wall, I have seen A-shaped crates put beneath them at six feet apart, so as to permit of heating them by fresh supplies of manure. It is, however, a plan possessing little claim to general use. It is best not to depend on the hand, as is commonly done, for ascertaining the heat of the beds. Thermometers fixed on sticks of con- venient size, to thrust in the beds, are sold, and remove all excuse for vagueness in this matter. Coverings of litter are sometimes useful in ^^ drawing-up the heat^^ in a bed that has become somewhat chilled. SPAWNING AND AFTER-TREATMENT. 35 Spawninf/. This is the phase of the culture which requires most attention, as to get the spa^vn to run regularly through the bed is to be nearly certain of securing a good crop. In this respect there do not seem to be so many differences of opinion among mushroom growers. Some^ indeed, spawn immediately after the bed is made up ; but, except where the materials are such as will not heat to more than 80 degrees, this is uncertain, or in other words bad, practice. The important thing should be to ascertain if the spawn spreads through the bed properly. The usual practice is to earth up the bed immediately or very soon after it is spawned, and not a few take no further notice of the bed or beds till the time arrives when the mushrooms ought to appear. A better plan is not to finally earth the bed until the spawn is seen beginning to spread its white filaments through the mass ; and should it fail to begin to do this in eight or ten days after spawning — the conditions being favourable — it is then better to insert fresh spawn or to re-make the bed, addiug fresh materials if it be found to fail from being too cold. If people generally were to see whether the spawn had " taken'' freely, instead of waiting for many weeks, not knowing whether it had or not, there would be fewer disappointments in mushroom culture. 1) 2 36 MUSHllOOM CULTURE. The ordinary spawn bricks should be broken into pieces, say from about the size of walnuts to that of eggs ; they do not break up into regular portions. Spawn in the more natural form in which we take it from the old beds, and in which it is used by the French, is ready to be inserted into the bed without any further manipulation. I be- lieve this kind of spawn spreads more rapidly through the beds than our own brick spawn, and is, on the whole, much more desirable. As it is usually very dry it is a good plan to place some of it in the mush- room-house a few days before spawning, so that it may begin to absorb moisture. A dark place in a warm house, or gentle hotbed, would do as well, but in no case should it be done more than three days before spawn- ing time. At spawning this might with advantage be mixed with some that has not gone through this process. A bushel of the ordinary brick spawn will suffice to spawn about one hundred square feet. All spawn should be inserted near the surface, just buried in the materials of which the bed is made. The thin flakes of spawn which the French use, and which arc usually nearly the length and breadth of the open hand, are gcncrallv inserted into the bed edgeways, or in a direction slanting upwards, so that while one edge of the piece is buried three or four inches in the bed, the other is seen peepiuir through at the surface. Thus each flake of spawn is exposed to a slight difference of temperature, and, being SPAWNING AND AFTER-TREATMENT. 37 thin and spongy enough to be immediately impregnated with the moist warmth of the beds, takes quickly aud well. As to any particular mode of insertiug the spawn, little need be said ; if the bed be beaten so liard as many recommend, and which I do not believe to be at all necessary, a dibber will be required to insert the spawn ; if not, it may be readily inserted with a trowel or with the hand. It is a good plan to use a mixture of two kinds of spawn. Soil. As regards the kind of soil used in earthing, it is not of nearly so much importance as is generally supposed; almost any soil will do ; but those having heaps of good maiden loam laid by for gardening purposes will prefer to use a coating of that. I believe that any ordinary garden soil would do, and feel certain that it is a mistake to bestow the least trouble on procuring any particular kind of soil from a distance. The beds in the caves around Paris are covered over with a white putty-like substance, which would be sufficient to shake the nerves of any British mushroom-grower accustomed to his coatings of mellow loam. It is simply the fine rubbish from the stone breakage moistened, and smoothly and firmly pressed over the beds. We, if shown this on a bed that had failed, would assuredly attribute it to the " stuff" 38 3IUSHR00M CULTURE. with wliicli the bed was covered,, thougli finer crops than these little beds yield it would be impossible to find. I notice this subject so that failures may be traced to their true causes, and not attributed to matters which really have but slight influence. The final covering of from one to two inches of loam or other soil should not be applied till the spawn has begun to spread through the bed, but a very thin layer of dryish loam may be placed on with advantage just after spawning has taken place, as it will serve to make the surface of a more equable temperature. It is a mistake to suppose that a deep covering is of any advantage. The final earthing should be of soil sufficiently moist or moistened to permit of its being pressed into a firm surface. However, unless it is exceptionally dry, a mere sprinkling of water will suffice. Watering, As the materials of mushroom-beds are generally moist, and as but little evaporation can take place in the structures in which they are usually grown, water is rarely necessary, and should not be applied until the surface of bed and soil are really dry. It should then be given copiously, enough to well moisten the bed, and it should be soft water heated to a temperature of 80 degrees given with a fine rose, and steadily and patiently applied equably over the whole surface of the bed. Waterings that merely wet the surface and saturate the crevices or SPAWNING AND Al'TER-TREATMENT. 39 lower parts of the bed are of no use. If one drenching is not sufiBcient to moisten the bed properly, another should be given. The flat form of bed is of course much more easily watered, and is on the whole the best for beds under cover. The position of beds will have a great in- fluence on the quantity of water they require, so that it is almost impossible to give precise directions on this head; but I can scarcely conceive a case in which it will be necessary before six or eight weeks after the formation of a bed, and I have seen fine crops gathered without a single water- ing having been given. In watering old beds one ounce of guano to the gallon of T\-ater will prove beneficial. Vermin in Mushroom Beds. Woodlice are the greatest pests the mushroom-grower has to dispose of, and the most eff'ective way of getting rid of them is by destroying them with boiling water. The surface of the bed being firm and covered with smooth firm soil, the only likely place to aff'ord these creatures the interstices they usually retire into when disturbed, or when not employed in eating the head of every little mushroom that presents itself, is round the edges of the bed, and in the slit which often occurs' between the bed and wall or sides of the shelves that support it. There they are likely to be found in great numbers, and may be destroyed wholesale by pouring boiling water all along the crack. If the beds be co- 40 MUSHROOM CULTURE. vered with hay or litter^ it will be necessary to remove this and allow them time to retreat into their hidinsj places ; and if the beds are made in any position that ^Dermits of the woodlice hiding in other places than the interstices round them^ these places should be sought out^ marked^ and receive a searching dose of the scalding water all at the same time. It need hardly be added that_, as it is not mushrooms, but creatures that rival ourselves in their love of mushrooms, that we wish to an- nihilate, the scalding water must not in any case be applied to the surface of the bed. If on the surface of old or dry beds, or those from which a good many mushi'ooms have been cut or pulled, there are any loose hollows or crevices in which the woodlice can take shelter, they should be sought out, cleared of vermin, levelled up, and made firm, so that the enemy cannot take up a position in which we cannot attack him. Should this plan fail, half an ounce of sugar of lead, mixed with a handful of oatmeal and laid in their tracks, will quickly destroy the pests. The small mite is most destructive in a high tempera- ture, and in summer, Mr. Cuthill says, " the maggot^' will not breed in a house where the temperature does not ex- ceed sixty degrees, and it is in hot, dry, and half-neglected houses that this pest is usually seen in summer. At that season there is little need to grow mushrooms indoors, and liow they may be produced otherwise in great abun- SPAWNING AND AFTER-TREATMENT. 41 dance is explained furtlier on. The entrance of rats should also be guarded against. Mushroom-beds come into bearing about six weeks from the time of spawning, and remain in bearing from two to five months^ according to the position in which they are made, and the attention paid to them. Treatment of Old Beds. Upon the continuous bearing qualities of a mushroom bed a word may be said. It may savour of the ridiculous to say that a plant growing upon a dung bed may fail from the want of manure. Yet such is literally and positively the fact. Beds become worn out, the produce small and spindly, and we directly do away with them and make fresh ones. Instead of doing this, give the bed a thorough soaking of stable urine and water, at the temperature of 80 degrees, using the urine in the propor- tion of one part to five of soft water, and adding a wineglass- ful of salt to each canful ; then coat the bed with fresh soil, cover it down with mats so as to promote the heating, and a second crop as good as the first may be obtained. In this matter I speak from experience, and ^Ir. Ingram, at Bel voir, has followed the same plan for many years with the most satisfactory result.- Gathering the Crop. Gatherings should frequently take place, especially 42 IMUSHIlOO^r CULTURE. where tlie culture is pursued on a large scale. Where there are several beds in bearings the mushrooms should be gathered every morning. In all cases they should be pulled or twisted out, never cut out, so as to leave decaying stumps in the beds. The holes made by pulling out the mushrooms should be filled with a little fine loam, of which a small heap may be kept in the house for this purpose. Cleansing the House. A word as to the necessity of a thorough annual cleansing of the mushroom-house. The fact that the French cave-cultivators find it necessary to shift from cave to cave, and find that after a cave has been in use a certain time, mushrooms cease to be produced in it, should act as a caution in this respect. In summer, when there is no need to attempt the culture indoors, the house should be thoroughly cleaned out, lime -whi ted, every surface scraped and washed, and the house freely opened, so as to thoroughly sweeten it. 43 CHAPTER Y. CULTURE IN SHEDS_, CELLARS, ARCHES, OUTHOUSES, AXD ALL ENCLOSED STRUCTURES OTHER THAN THE MUSH- ROOM-HOUSE. ]NrusHROOMs may be, and are, grown to perfection in many less ambitious structures than the mushroom-house proper. Any species of outhouse will do for the autumn and early winter crops. One of the best crops I have ever seen was grown in a dry and unused coach-house. Mr. Robert Fish grows all his crops in a long, low, rude thatched shed, open in front — the beds flat, in a con- tinuous line against a wall, and enclosed by a low board. Mr. Cuthill, who wrote on mushrooms, and who used to grow them very well, grew his in rude sheds placed against walls. It matters not in the least if the shed be open or ventilated here and there, especially for autumn crops, as I have seen admirable crops in low outhouses searched by every gust, and not heated by flues. The beds in these should always be covered with hay. Mushrooms may be grown in cellars ; but cellars being commonly under houses, they are not exactly the 44 MUSHROOM CULTURE. places to wMcli people like to convey the materials necessary for the makinor of mushroom-beds. Where they occur away from a dwelling-house, this objection will not hold good. In some cases it might be ob- viated by making the beds in rough boxes_, say 3^ ft. long by 1| ft. wide, and afterwards introducing them into the cellar. Railway or other arches, or any dry and empty structures, may be used for mushroom- growing. " The construction,^^ says Mr. William Ingram, of Belvoir, in a letter to the Field, " of efiScient mushroom- houses is sufficiently understood by most of our hothouse- builders and by gardeners ; but the economical adapta- tion of places which already exist is a matter which may with the greatest advantage be discussed, as there are hundreds of persons about whose establishments may be found outhouses, cellars, quarries, or sheds, capable of conversion into mushroom-houses, who would be very glad to be taught the method of growing mushrooms, and to have the simple principles that should govern the construction of mushroom-houses explained. " There are few large farmsteads that are without an unconsidered place which could be readily adapted for the purpose of growing mushrooms ; and farmers possess the material at hand, horse manure, which would not suffer great deterioration if employed in first raising a crop of mushrooms. Country brewing establishments have equal conveniences and opportunities. By relating the CULTURE IN SHEDS, ARCHES, ETC. 45 means by "which I have been for several years able to raise large quantities of excellent mushrooms, in a place originally but ill adapted for the purpose, I may induce some of those persons who desire the luxury of what Sover called ^ the Pearl of the Fields/ to turn their attention to the subject of their growth. " I had a large, open, airy shed at command, but it was liable to be affected by changes in the weather, and was altogether too draughty and cold in winter, and too hot in summer. I built within this shed, with rough fir boards, an inner shed, 18 ft. long, 6 ft. wide, and 8 ft. in height ; two receptacles for beds were formed, one on the floor, the other above it : and to give the requisite heat in winter, I passed a flue, formed of 9-in. socket pipes, through the house ; with this I can always command an adequate amount of heat. The material of which the beds are formed is chiefly droppings, collected from an enclosed and covered exercise ground. These drop- pings are trampled by the horses, and mixed with straw broken up with the manure by the passage of the horses. " When first collected it is piled up in a large heap, in a perfectly dry state, and when wanted for the bed is thrown out, sprinkled with water, and fermented for about a week ; while hot, it is taken to the house, and as it is thrown in is mixed with a small quantity of soil of a loamy character, and a barrow-load of leaf soil. 46 MUSHROOM CULTURE. It is tlien pressed into as compact a mass as possible by a rammer or mallet, building it np until it forms a bed 10 in. thick in front and 20 in. at tlie back. After a bed formed of this description of materials has been thus put together, rapid fermentation takes place ; and when the most violent fermentative action has passed^ and a temperature of 80° is found in the bed, spawn is put into it by means of a dibber. I employ brick spawn obtained from good makers, but, to vary and possibly prolong the period of production, I introduce a certain quantity of spaw^n saved from old beds. This is longer in its development than the made spawn, and appears as a subsidiary crop. After the bed is spawned^ a covering of compact loamy soil is spread on the surface^ IJ- in. to 2 in. in thickness, and w^eli beaten upon it so as to form a smooth and hard crust. A temperature ranging from 50° to 60° should be maintained in the house. A lower temperature abstracts the heat from the bed more rapidly. '' When the mushrooms begin to exhibit weakness, as after the bed has produced a certain quantity they will do, from the exhaustion of the more stimulating portions of the manure^ I find it an excellent practice to ad- minister a sprinkling of water in which a handful of salt has been thrown (that quantity of salt to a three-gallon can). Saltpetre, though in much smaller quantities, is equally valuable given in the same way. The practice CULTURE IX SHEDS, ARCHES, ETC. 47 I have described relates to the "vvinter cultivation of mushrooms/^ Many instances of perfect success like the preceding could be quoted. Here is one from Mr. W. P. Ayres : — '' You will be glad to hear that we have on the out- skirts of this town (Nottingham) a grower of mushrooms (Mr. Cookson, Mansfield Road) who vies with the French growers,, especially if the means of growth be taken into consideration. The place he occupies was formerly the pleasure garden of a large hotel, where the proprietor would occasionally, in the summer season, treat his friends and patrons to an al fresco entertainment. For this purpose a range of summer-houses was built, con- sisting of brick arches, say 12 feet deep, 6 feet wide, and a little more in height. Close adjoining is a small sandstone-rock cellar, w^hich used to serve for drinkables in the summer and potatoes in the winter. " Some twelve months ago these premises and the house adjoining fell into the occupation of a gardener, who, though he had a licence to the house, fancied he might turn the arches to a better purpose, and hence he de- voted them to mushroom beds. As it was necessary that the arches should be closed, a wall about three feet higli was built in the rudest manner parallel with their front, but six feet from it, and from, that a roof of rough timber was thrown, and covered with asphalted felt. Here, however, was a mistake ; for, the building stand- 48 MUSHROOM CULTURE. ing due souths when the sun fell upon it the atmosphere became rather ' tarry ^ — so much so that the mushrooms refused to grow in it. That wore off after a time, and from a bed not more than thirty yards square the tenant told me he had cut more than 25/. worth of mushrooms. When I saw the beds they might be considered spent, the flush of early youth was over ; but still the crop was most wonderful, especially considering the means at com- mand. " In the rock cellar the small beds were a pavement of splendid mushrooms^ many of them as large over as a cheese-plate, and thick in proportion. In the garden is a barn — four walls with a roof over them, the latter so rude that it was only in fair weather that it could be called waterproof. In this place, which may be 25 ft. long by 15 ft. wide, two tiers of beds have been put up, the roof has been made waterproof, a common brick flue put through it, and, at the time I saw them, more pro- mising beds could not be desired. Here again, you will perceive expensive appliances are not necessary for the production of mushrooms. ^^ Stables and like structures off'er capital positions in which successful mushroom culture may be carried out with ease. If it is possible, and we know it is not only possible but easy, to grow mushrooms in boxes a few feet long and a foot or eighteen inches wide, and the same depth, it is CULTURE IN SHEDS, ARCHES, ETC. 49 clear that tlierc can be no difficulty about growing tliem in abundance in such a manner as that shown in the accompanying engraving. This mode was actually prac- tised with great success by the Baron Joseph d^Hoogvorst^ of Limmel. Fi;?. 14. Musliroom culture on shelves in stable. The culture was carried out in neatly fitted-up wooden boxes, so arranged that they might be shrouded with canvas curtains as shown in the engraving, so tliat at first sight £ 50 MUSHROOM CULTURE. one would not suppose that mushroom culture was carried on there. No evil results as regards the creation of an unhealthy atmosphere accompanied the attempt. The beds were formed much in the usual way from the droppings of highly fed horses. Now there can be no doubt that a similar mode of growing mushrooms could be carried out in the stables or some adjacent build- ing in hundreds of places apart from the garden and the gardener altogether. Given the materials and some position^ however contracted^ in which to carry out the culture^ and both these things are surely to be had almost in every 'place where there is a stable^ the rest is so simple that any stableman or boy could carry it out. We know that these individuals^, as a class^ are not much given to botanical or horticultural studies^ but no doubt the pro- spect of an occasional half-dozen fresh mushrooms on the gridiron would give them most praiseworthy interest in the culture. The only objection to it is_, or might be_, that once they were at home in the culture, the gardener would be very likely to fall short of materials for his hot- beds. An empty loft, or any other covered structure could be employed as well as the stable or an empty coach- house. Apart altogether from utilizing the walls of the stable, as the Baron did, empty stalls frequently present an opportunity of growing mushrooms in quantity. These remarks apply to stables in cities and towns, as well as in the country ; indeed in cities, particularly in London, CULTURE IN SHEDS, ARCHES, ETC. 51 stable manure is usually so plentiful tliat it is much easier to obtain and much cheaper than in the country^ so that even those in London having suitable places for growing mushrooms, but not keeping horses regularly or at all, could have no difficulty in procuring abundance of materials. The French often cultivate mushrooms in cellars as well as in the caves described in the next chapter. Preference should be given to a dry warm cellar; it should be as dark as possible, and exposed to no draughts. Beds can be made in cellars in many ways. Those made in the middle should alwavs be formed with two sides, while those against the walls should only be half as thick, on account IEI V \s Hk' L> «?^> >^^ C '< ^ I^Doa' ^ S^ TO i i^^bewL ^ ^j HlK S^. V ■" C Fig. 15. Mushroom-bed on rude shelf against wall of cellar. of their having only one useful side. It is also possible to arrange them on shelves, one above the other. For this purpose strong bars of iron are driven into the walls, upon which are placed shelves of the proper size covered with earth, upon which is formed a bed, tliat is treated exactly as those made upon the ground. These beds arc just as productive as any of the otlicr kinds. E 2 5:2 MUSHROOM CULTURIi. They mav even be made on the bottoms of casks, which should be at least two feet six in diameter ; and they Tig. 16.

Mushrooms gro^yn i.i bottom of old cask, ond a quarter deep, and sixteen inches apart. A barrel is saw., cvossways into two pieces, each formmg a tub. CULTURE IN SHEDS, ARCHES, ETC. 53 Holes arc made in the bottom of each, aud a thin layer of good soil is spread over them inside. They are then filled with good well-prepared stable manure, just like that used in the case of ordinary mushroom-beds, the different layers of dung in each tub being well pressed down. ^Yhen the tub is half full^ six or seven good pieces of spawn are placed on the surface, and the re- mainder is piled up with manure, which is well pressed down, the operation being completed by giving to the heap the form of a dome. The tubs thus prepared are placed in a perfectly dark part of a cellar, and eight or ten days afterwards the dung is taken up until the spawn is visible, in order to see whether it has commenced to vegetate and develop little filaments. If the spawn has spread, the surface must be covered with soil, care being taken to use only that which is fresh and properly pre- pared. In this or any like way there should be no difficulty in growing mushrooms : the boxes or tubs could be filled anywhere, and then carried into the spare cellars, &c. In this way objections against steaming manure might in many cases be got over. Among the many and various structures in which mushrooms may be grown, but which we rarely see utilized for that purpose, may be mentioned all kinds of greenhouses, stoves, pits, and frames. Some of the best crops I have ever seen were in cold greenhouses ahnost too ruinous to grow anything else. In mid- winter the 54 MUSHROOM CULTURE. floors of all liouses in which a genial temperature is kept up for forcing or other purposes^ oifer excellent positions for producing mushrooms quickly and abundantly. Small ridge-like beds might be made on the floor of these, and, ydth the genial temperature usually kept up in such places, would probably come into bearing a month or so after being spawned. How often, for example, do we notice the floors of large vineries, in mid-winter or very early spring, quite bare, especially after the "vines are started. Now just at that season the genial heat that would be given off" from the slightly fermenting materials used for the mushroom-bed is that which would be most congenial to the tender breaking vines, and with a little attention in this way a first-rate crop of mushrooms could always be gathered from the early vinery, and in houses where no artificial heat was applied they could also be grown abundantly. A covering of hay would, however, be necessary in cold houses in mid- winter, to prevent excessive variation of the temperature, and also in spring and summer to prevent excessive drying or scorching of the beds by a hot sun. I have even seen excellent crops grown on the floor in an old lean-to house, the beds covered with a foot or so of hay, occa- sionally sprinkled with water to prevent excessive heat on the surface of the bed. In small places where every foot of space in the glass-house is likely to be occupied with plants, it is not easy to carry out the foregoing CULTURE IN SHEDS, ARCHES, ETC. 55 suggestions^ but even if a small early vinery Tvere occu- pied with plants^ it Avould be desirable and practicable to introduce a series of rough boxes devoted to mush- room culture. Apart from empty greenhouses altogether, the space beneath the stages in numbers of glass-houses of every type may be utilized for the production of mushrooms. These positions are usually unoccupied, occasionally they are used for storing fuchsias, &c. in Tvinter, but very seldom arc they turned to so good account as they might be in the way I recommend. The stage in the small greenhouse is frequently elevated so that there is plenty of room to get beneath it: if at the back or end there is no way of walking readily under the stage, an opening should be made. The only difficulty that could possibly occur would arise from the drip from the plants on the stage above. This, liowever, can be easily guarded against by spreading a piece of tarpaulin or oil-canvas over the bed or beds. AVith beds properly made, a coat of dry hay or litter, and a piece of tarpaulin^ every owner of anything in the shape of a greenhouse with a stage in it may grow mushrooms throughout the autumn, winter, and spring months, and even in summer by keeping the surface of the hay or litter moist. Of course, if there be room for but one bed, a succession cannot be kept up, and in this case a bed should be made in autumn^ which, if well managed, should be in full bearing for a month or six 56 MUSHROOM CULTURE. weeks before and after Christmas. There are^ however, numerous spaces such as those alluded to where there is room to make a succession of beds. No person having but one greenhouse need fear much or any inconvenience from the odour of the manure — at least, not after the beds are earthed. The couple of inches of soil over the manure would absorb any vapour given off by the bed. Wherever the cultivation of cucumbers or melons in pits or frames is carried out, nothing can be easier than to grow large crops of mushrooms after the melons, &"c. are cleared away. The spawn may be inserted over the surface of the little mounds usually made for the reception of the young melon plants, and also over the remaining surface of the beds which are generally covered with a few inches of earth. After the melons have done bearing and the haulm is cleared away, the spawn will usually be found to have spread through the deep mass of earth in the beds. As little or no water is given or required while the melons are ripening, a good soaking of tepid water will generally be necessary to encourage the mushrooms to start into profuse bearing. If the season and situation be mild and warm, the lights may be taken off; and if the sun be very strong, the beds may be shaded with canvas or mats. If the season be late and cold it will, on the other hand, be desirable to keep on the lights, and even to cover them in cold weather. 0/ CHAPTER YI. THE CAVE CULTURE OF MUSHROOMS_, NEAR PARIS. The most extensive and successful culture of muslirooms in existence is carried on in widely- ramifying caves far beneath the surface in the vicinity of Paris. To give the reader as good an idea of it as I can we must visit one of the great ^' ^Mushroom caves^^ at Montrouge, just outside the fortifications of Paris^ on the southern side. The surface of the ground is mostly cropped with wheat ; but here and there lie, ready to be transported to Paris, blocks of white stone, which have recently been brouglit to the surface through coalpit-like openings. There is nothing- like a " quarry/^ as we understand it, to be seen ; the stone is extracted as we extract coal, and with no inter- ference whatever with the surface of the ground. AVe find a " champignonniste^' after some trouble, and he accompanies us across some fields to the entrance of his subterranean garden. It is a circular opcniug like the mouth of an old well, but from it protrudes the head of a thick pole Avith sticks thrust through it. This pole, the base of which rests in darkness sixty feet below, is the 58 MUSHROOM CULTUKE. J- f i ^ I THE CAVE CULTURE OF MUSHROOMS. 59 easiest and indeed the only Tvay by which human beings can get into the mine. I had an idea that one might enter sideways and in a more agreeable manner, but it was not so. Down the shaky pole my guide ereeps, I follow, and soon reach the bottom, from which little passages radiate. A few little lamps fixed on pointed sticks are placed below, and, arming ourselves with one each, we slowly commence exploring dark, still, tortuous passages. I have heard that the first individual who commenced mushroom-gi'owing in these catacomb-like burro wings was one who, at a particularly glorious epoch of the history of France, when a great many more brave gar9ons went to fight than returned from the victory, preferred, strange to say, to stay at home and hide him- self rather than form a imit in " battlers magnificently stern array. "" Industrious and discreet youth ! You deserve being held up as an example as much as the busy bee that improves each ^^ shining horn-." The passages are narrow, and occasionally we have to stoop. On each hand there are little narrow beds of half- decomposed stable manure running along the wall. These have been made quite recently, and have not yet been spawned. Presently we arrive at others in whicli the spawn has been placed, and is '^ taking' freely. Tlie spawn in these caves is introduced into the little beds in flakes taken from an old bed, or, still better, from a heap of stable manure in which it occurs naturally. 60 MUSHROOM CULTURE. Such spawn is preferred,, aud considered much more valuable than that taken from old beds. Of spawn in the form of bricksj such as is used in England^ there is none. Fig. 19. Xewl3'-made bed against wall of cave. The champignonniste pointed with pride to the way in which the flakes of spawn had begun to spread through the little beds^ and passed on — sometimes stooping very low to avoid the pointed stones in the roof — to where the beds were in a more advanced state. Here we saw little, smooth^ putty-coloured ridges running along the sides of the passages, and wherever the rocky subway became as large as a small bedroom two or three little beds were placed parallel to each other. These beds were new, and dotted all over with mushrooms no biscsrer than sweet pea seeds, affording an excellent prospect of a crop. Each bed contains a much smaller body of manure than is ever the case in our gardens. They are not more than twenty inches high, and about the same width at the base ; while those against the sides of the passages arc not so large as those placed in the open spaces. The THE CAVE CULTURE OF MUSHROOMS. CI soilj with whicli they are covered to the depth of about an inch J is nearly "white, and is simply sifted from the rubbisli of the stone-cutters above, giving the recently-made bed the appearance of being covered with putty. Although we are from seventy to eighty feet below the surface of the ground, everything looks quite neat — in fact, very much more so than could have been expected, not a particle of litter being met with. A certain length of bed is made eveiy day in the year, and as the men finish one gallery or series of galleries at a time, the beds in each have a similar character. As we proceed to those in full bearing, creeping up and down narrow passages, winding always between the two little narrow beds against the wall on each side, and passing now and then through wider nooks filled with two or three little beds, daylight is again seen. This time it comes through another well- like shaft, formerly used for getting up the stone, but now for throwing down the requisite materials into the cave. At the bottom lies a large heap of the white earth before alluded to, and a barrel of water — for gentle waterings are required in the quiet, cool, black stillness of these caves, as well as in mushroom-houses on the upper crust. Once more we plunge into a passage as dark as ink, and find ourselves between two lines of beds in full bear- ing, the beautiful white button-like mushrooms appearing everywhere in profusion along the sides of the diminutive 62 MUSHROOM CULTURE. beds^ something like the drills which farmers make for green crops. As the proprietor goes along he removes sundry bunches that are in perfection^ and leaves them on the spot, so that they may be collected with the rest for to-morrow^'s market. He gathers largely every day, occasionally sending more than 400 lb. weight per day, the average being about 300 lb. A moment more and we are in an open space, a sort of chamber, say 20 feet by 12, and here the little beds rig. 20.

There is one THE CAVE CULTURE OF MUSHROOMS. 63 exception ; on half of the bed and for about ten feet along, the little mushrooms have appeared and are appearing, but they never get larger than a pea, and shrivel away, ^^ bewitched^' as it were. At least such was the inference drawn from the cultivator's expression about it. He gravely attributed it to a ridiculously superstitious cause. Frequently the mushrooms grow in bunches or ^^ rocks,^^ as they are called, and in such cases those that compose the little mass are lifted all together. The sides of one bed here had been almost stripped by the taking away of such bunches, and it is worthy of note that they are not only taken out, root and all, when being gathered, but the very spot in w^hich they grew is scraped out, so as to get rid of every trace of the old bunch, and the space is covered with a little earth from the bottom of the heap. It is the habit to do this in every case, and when the gatherer leaves a small hole from which he has pulled even a solitary mushroom, he fills it with some of the white earth from the base, no doubt intending to gather other mushrooms from the same spots before many weeks are over. The ^' buttons^^ look very white, and are apparently of prime quality. The absence of all littery coverings and dust, and the daily gatherings, secure them in what we may term perfect condition. I visited this cave on the 6th of July, 18G8, and doubt very much if at that season a more remarkable crop of mushrooms could be anywhere found than was presented 64 MUSHROOM CULTURE. in this subterranean chamber — a mere speck in the space devoted to mushroom culture by one individual. When I state that there are six or seven miles run of mushroom-beds in the ramifications of this cave, and that the owner is but one of a large class who devote them- selves to mushroom culture, the reader will have some opportunity of judging of the extent to which it is carried on about Paris. These caves not only supply the wanes of the city above them, but those of England and other countries also, large quantities of preserved mushrooms being exported, one house alone sending to our own country no less than 14,000 boxes annually. There were some traces of the teeth of rats on the pro- duce, and it need not be said that these enemies are not agreeable in such a place ; but they did not seem to have committed any serious ravages, and are probably only casual visitors, who take the first opportunity of obtain- ing more varied food than is afforded them by these caves. To traverse the passages any further is needless — there is nothing to be seen but a repetition of the culture above described, every available inch of the cave being occupied. We again find our way to the bottom of the shaft, carefully mount the rather shaky pole one at a time, and again stand in the hot sun in the midst of the ripe wheat. In traversing the fields two things relating to mush- room culture are to be observed — heaps of white gritty THE CAVE CULTURE OF MUSHROOMS. G5 earth, sifted from the debris of the white stouc, and large heaps of stable manure accumulated for mushroom growing, and undergoing preparation for it. That pre- paration is different from what we are accustomed to give it. It is ordinary stable manure, or very short stuff, not droppings, and is thrown into heaps four or five feet high, and perhaps thirty feet wide. The men were employed turning this over, the mass being afterwards stamped down with their feet, a water-cart and pots being used to thoroughly water the manure where it is dry and whitish. As many will feel an interest in the cave culture of the mushroom, and perhaps wish to see it for themselves, I may state that it is difficult to obtain permission to visit the caves, and many persons would not like the look of the ^Hadder^^ which affords an entrance. Even with a well-known Parisian horticulturist I had some difficulty in entering them. I was informed that one champignonnistc in the same neighbourhood demands the exorbitant price of twenty francs for a visit to his cave. As the visit is the work of some little time, no visitor should put the cultivators to this trouble without offering some slight recompense — say not less than five francs. The above cave is but a sample of many in the im- mediate neighbourhood of Paris. We will next visit a mushroom-cave of another type at some little distance from that city. It is situated p 66 MUSHROOM CULTURE. near Frepillon, Meiy-sur-Oise — a place whicli may be readied in an liour or so by the Chemin de fer du Nord, passing by Engbien, the valley of Montmorency and Pontoise, and alighting at Auvers. There are vast quarries in the neighbourhood,, both for budding-stone and the plaster so largely used in Paris. The materials are not quarried in the ordinary way by opening up the ground, nor by the method employed at Montrouge and elsewhere in the suburbs of Paris, but so that the interior of the earth looks like a vast gloomy cathedral. In 1867 the mushroom culture was in full force at Mery, and as many as 3000 lbs. a day were sometimes sent from thence to the Paris market ; but the mushroom is a thing of peculiar taste, and these quarries are now empty — cleaned out and left to rest. After a time the great quarries seem to become tired of their occupants, or the mush- rooms dislike the air ; the quarries are then well cleaned out, the very soil where the beds rested being scraped away, and the place left to recruit itself for a year or two. In 1867 M. Renaudot had the extraordinary length of over twenty-one miles of mushroom-beds in one great cave at Mery ; last year there were sixteen miles in a cave at Frepillon. This is a clean, lonely vdlage, just touching on the gigantic cemetery which M. Haussmanu projected. The distant view of the entrance to the quarries has much the appearance of an English chalk-pit. But THE CAVE CULTURE OF MUSHROOMS. 67 there is a great iiidc arcli cut into the rock, and into this we enter, meeting presently a waggon coming forth with a load of stones, the waggoner with lamp in hand.

The tunnel we traverse is nearly regularly arched_, masonry being used here and there^ so as to render the support Fig. 22. Plan of large subterranean quarry at Fortes Terras, Frepillon.

G9 secure and somewhat symmetrical, the arches being flat at the top for six feet or so, and about twenty-five feet high ; sometimes five feet higher. Presently we turn to the right, and a scene like a vast subterranean rock temple presents itself. At one end are several of us with lamps, admiring the young mush- rooms budding all over the rows of beds, which, serpent- like, are long and slim, and coil away into the darkness. At about 150 feet distance there is a group of three men Fig. 23. Section following the line C, D, in Fig. 22. and a boy, each with a lamp, again dispelling the dark- ness from the mushroom beds, and occupied in placing small quantities of a sort of white clayey sand in the spots whence gatherings have been made a few hours previously. From both sides of this gloomy avenue the dark openings of others depart at short intervals, and the floor of all is covered with mushroom-beds, sometimes running along the passages, sometimes across them. These ])cds arc 70 :\1USHR00M CULTURE. about twenty-two inches high and as much in diameter, and are covered with silver sand and a sort of white putty-like clay in about equal proportions. Running along in parallel lines, and disappearing from view in the dark- ness, one knows not what to compare them to, unless it be to barked pine trees in the hold of a ship. Everywhere on the surface of these little beds small mushrooms were peering forth in quantity ; as the beds are regularly gathered from every day, no very large ones are seen. They are preferred wdien about the size of a chestnut, and are removed root and branch, a small portion of finely sifted earth being placed in each hole, so as to level the bed as in the caves at Montrouge. If the old superstition that a mushroom never grows after being seen by human eyes were true, the trade of a champignonniste would never answer here, as the little budding individuals come within view every day during the gathering and earthing operations. The most perfect cleanliness is observed everywhere in the neighbourhood of these beds, and the whole surface of each avenue is covered by them, leaving passages of ten inches or a foot between the beds. At the time of my visit (Sept. 29, 1868) the crops of the cultivator were reduced to their lowest ebb, and yet about 400 lbs. per day were sent to market. The average daily quantity from this cave is about 880 lbs., and sometimes that is nearly doubled. In some parts of the cave the work of ripping out the THE CAVE CULTURE OF MUSHROOMS. 71 stone by powder and simple machinery continually goes on. The arches follo^y the vcining of the stone, so to speak ; their lower parts are of hard stone, the upper ones of soft, except the very top, which is again hard. There is but a slight crust of stone above the apex of each arch, and above that the earth and trees. It may be supposed that the profits from such an ex- tensive culture are great ; and so they are, but the expense is great also. The proprietor informed me that culture on a more limited scale than he pursued last year at ^lery gave the best return in proportion to expense, the care and supervision required by so many miles of beds being too great. All the manure employed is brought from Paris by rail, as the place is twenty-five miles from that city by road. In the first place, so much per month is paid in Paris for the manure of each horse ; then it has to be carted to the railway station and loaded in the waggons ; next it is brought to the station of Auvers, and afterwards carted a couple of miles to the quarries, paying a toll for a bridge over the Oise on the way. That surely is difficulty enough for a cultivator to begin with ! Then it is placed in great flat heaps a yard deep by about thirty long and ten wide, not far removed from the mouth of the cave, and here it is prepared, turned over and well mixed three times, and as a rule watered twice. About five or six weeks are occupied in the preparation, long manure requiring more time than 72 MUSHllOOM CULTURE. short. The watering is not usually done regularly over the mass, but chiefly where it is dry and overheated. Every day manure is brought from Paris ; every day new beds are made and old ones cleared out— the spent manure being rig. 24. Extracting the stone in subterranean quarries. used for garden purposes, particularly in surfacing or mulching, so as to prevent over-radiation from the ground in summer. The chief advantage the cultivator here basis the facility of taking his manure or anything else in or out THE CAVE CULTURE OF MUSHROOMS. 73 in carts_, as easily as if tlic beds were made in the open air. Near Paris, on tlie contrary, everything has to be sent up and down through shafts like those of an old well, and the men have to creep up and down a rough pole like mice. Many men are employed in the culture, the daily examina- tion of sixteen miles of beds being a considerable item in itself. Here and there a barrier in the form of straw nailed between laths may be seen blocking up the great arch to a height of six feet or so. This is to prevent currents of air wandering about through the vast passages. The mode of preparing the spawn here is entirely different to ours. They prefer virgin spawn — that is to say, spawn found naturally in a heap of manure. But as this material cannot be obtained in sufficient quantity to meet the wants of such extensive growers, they put a small por- tion of it into a mushroom-bed to spread, and instead of allowing this bed to produce mushrooms, it is all used as spawn, and is valued more than any other. Of course abundance of spawn occurs in the old beds, but it is never used directly. It is, hoAvcver, frequently emjiloycd to spawn a small bed when virgin spawn cannot be obtained. In this case the small bed devoted to the propagation of spawn is placed in the open air, and covered with straw, and as soon as it is permeated with the spawn it is carried into the caves and used. As the making and spawning of beds is a process continually going on, a bed of this sort must be ready at all times. It is never made into bricks 74 MUSHROOM CULTURE. as with us^ but simply spread through shorty partly-decom- posed_, manure."^ I was informed that coal-mines are not adapted for grow- ing mushrooms, and the smallest particle of iron in the beds of manure is avoided by the spawn, a circle around it remaining inert. It is said to be the same with coal. If an evil-disposed workman wishes to injure his employer, he has only to slip along by the beds with a pocketful of rusty old nails, and insert one here and there. Fig. 25. View in old subterranean quarries devoted to mushroom cul- ture, and in the occupation of M. Renaudot. Sept. 29, 1868. The beds remain in good bearing generally about two months, but sometimes last twice and three times as long. A useful contrivance for facilitating the watering of the * Mr, Speed, superintendent of the gardens at Chatsworth, has re- cently prepared his own spawn, as described on p. 73, and with perfect success. THE CAVE CULTURE OF MUSHROOMS. 75 beds has lately been invented ; it consists of a portable "water-cistern to be strapped to the baek and fitted with a rose and tubing, so that a workman may carry a larger quantity of water, and apply it more regularly and gently than with the old-fashioned watering-pots — while one hand is left free to carry the lamp. An iron frame has also been invented, in which the bed is first compressed and shaped, the frame being then reversed and the bed placed in position. Another invention for earthing the beds over as soon as the spawn has taken will soon be in operation if not already so. As on an average 2500 yards of beds are made every month, simple mechanical contrivances to facilitate the operation will prove of the greatest ad- vantage to the cultivator. In addition to the caves in the localities above al- luded to there are other places near Paris where the culture is carried on — notabl}^ at ^loulin dc la Roche, Sous Bicetre, near St. Germaine, and also at Bagneux. The equability of temperature in the caves renders the culture of the mushroom possible at all seasons ; but the best crops are gathered in winter, and consequently that is the best time to see them. I, however, saw abundant crops in the hottest part of the very hot season of 18G8. These mushroom caves are under Govern- ment supervision, and are regularly inspected like any other mines in which work is going on. As regards the depth at which this culture is practised^ it usually varies 76 MUSHROOM CULTURE. from twenty to one hundred feet_, sometimes reaching one hundred and fifty and one hundred and sixty feet from the surface of the earth. They are so large that sometimes people are lost in them. In one instance the proprietor of a large cave went astray^ and it was three days before he was discovered;, although soldiers and volunteers in abundance were sent down. Is it possible that in a great mining and excavating country like ours we cannot establish the same kind of industrv ? CHAPTER VII. CULTURE ON PREPARED BEDS IN THE OPEN AIR IN GARDENS AND FIELDS. Mushrooms may be grown with ease in the open air in gar- dens ; and this is a phase of the culture with which gar- deners are not by any means sufficiently conversant. In fact, mushroom-culture in the open air in private gardens may be said not to exist at present, so very rarely is it seen. In a little pamphlet on mnshroom-growing that has lately appeared I find it stated that mushrooms may be grown out of doors " in summer/^ but nothing about them be- ing grown in the open air in winter. The Paris growers never attempt their culture in summer : the London ones very rarely. It is in winter that their cultivation is carried on in full vigour in the open air. Abundant crops are grown in the open air by the market-gardeners of London and Paris. From their beds mushrooms are gathered in quantities in mid-winter as well as in autumn. The Paris market-gardener docs not attempt the culture in mid-summer, and docs not think it practicable ; but in the hot summer of 18G8, and in the midst of tlie heats 7S MUSHROOM CULTURE. of July, I found about half an acre of ground at Erompton covered "with, musliroom-beds bearing well. The following illustration is from a sketch taken in Nov. 1869, in market-garden fields, between Kensington and Brompton. The "Kf^ds, about three and a half feet high and the same in width at the base, are covered with the long straw or litter taken from the stable manure. Over that is placed old bast mats, or any like materials, Fig. 26. Mushroom-beds in market-gardens at Earl's Court, Kensington. November, 1869. to keep the litter in its place, and throw off the rain ; the mats being kept in place by tiles, bricks, old boards, or any like objects that may be at hand. This is well shown in my illustration. The manure employed is that brought from the London stables, the longer litter being shaken out and put on one side to cover the beds. No care whatever is taken in the preparation of the manure ; it is usually made CULTURE IN THE OPEN AIR. 79 into beds soon after it is brought home and before it is allowed to lieat_, and then the beds are made in the form of potato-pits and beaten very firm. The beds arc spawned when at about a temperature of eighty degrees, the pieces of spawn being placed about a foot or so apart, and it is then immediately earthed, the ordinary soil being used, and the bed covered to a thickness of a couple of inches. The success attained by the market- gardeners of both London and Paris, with the ordinary soil of the place in which the beds may be made, well proves the absurdity of seeking for any particular kind of soil for covering mushroom-beds. Beds made in this way in the autumn and winter months, and covered with a thick layer of litter and mats, seldom require any watering. The culture is not usually attempted in summer; the heat acting upon the littery covering giving rise to insects which destroy the mushrooms ; but with care their culture is quite practicable at that season ; in proof of which I may say that during the last week of July, 1868, I saw them gathered freely in a market-garden just beside the Gloucester Road Station of the Metropolitan Railway, where by using a coating of litter about a foot thick, and over that a layer of mats, it was possible to procure them in good condition throughout the hottest summer within memory. There are many acres of ground covered Avith beds made thus in the market- gardens round London. 80 MUSHROOM CULTURE. We will next turn to the culture of the mushroom in the open air near Paris. In old times the market-gardeners there used to grow it amongst their ordinary crops with great profit^ but since the champignonnistes cultivate it under no danger from cold in the caves^ the market- gardeners_, who used to raise it to a great extent in the open air, do so now in a less degree. They begin Fig. 27. Uncovered end of musliroom-bed in Paris market-garden. January, 1867. with the preparation of the manure^ and collect that of the horse for a month or six weeks before they make the beds ; this they prepare in some firm sj)ot of the market- garden^ and take from it all rubbish,, particles of wood, and miscellaneous matters; for, say they, the spawn is not fond of these bodies. After sorting it thus, they place it in beds two feet thick, or a little more, pressing it with the fork. When this is done the mass or bed is CULTURE Ix\ THE OPEN AIR. SI well stamped, then thoroughly watered,, and finally again pressed down by stamping. It is left in this state for eight or ten days, by which time it has begun to ferment, after which the bed ought to be well turned over and re-made on the same place, care being taken to place the manure that was near the sides of the first-made bed towards the centre in the turning and re-making. The mass is now left for another ten days or so, at the end of which time the manure is about in proper con- dition for making the beds that are to bear the mush- rooms. Little ridge-shaped beds — about twenty-six inches wide and the same in height — are then formed in parallel lines at a distance of twenty inches one from the other. In a market-garden they may stretch over a consider- able extent, their length being determined by the wants of the grower. The beds once made of a firm, close- fitting texture, the manure soon begins to warm again, but does not become unwholesomely hot for the spread of the spawn. When the beds have been made some days, the cultivator spawns them, having of course as- certained beforehand that the heat is genial and suitable. Generally the spawn is inserted within a few inches of the base, and at about thirteen inches apart in the line. Some cultivators insert two lines, the second about seven inches above the first. In doing so, it would of course be well to make the holes for the spawn in an alternate manner. Tlie spawn is inserted in flakes about the size G S2 MUSHROOM CULTURE. of three fiiigei^, and then the mannre is closed in over, and pressed firmly around it. This done, the beds are covered with about six inches of clean litter. Ten or twelve days afterwards the growers visit the beds, to see if the spawn has taken well. When they see the white filaments spreading in the bed they know that the spawn has taken ; if not, they take away the spawn they sup- pose to be bad and replace it with better. But, using good spawn, and being practised hands at the work, they rarely fail in this particular ; and when the spawn is seen spreading well through the bed, then, and not before, they cover the beds with fresh sweet soil to the depth of about an inch or so. For cover, the little pathway between the beds is simply loosened up, and the rich soil of the market-garden applied equably, firmly, and smoothly with a shovel. With these open-air beds they succeed in getting mushrooms in winter. A covering of abundance of litter is put on immediately after the beds are earthed, and kept there as a protection. They have not long to wait till the beds are in full beariag, and when they are in that state it is thought better to examine and gather from them every second day, or even every day where there are many beds. And thus they grow excellent mushrooms, and in great quantity, all the further attention required being to renew the covering when it gets rotten, and an occasional watering in a very dry season. CULTURE IX THE OPEN AIR. 83 Of course tliis kind of cultivation is perfectly practi- cable in private gardens — wliere^ however, I liaA^e not yet seen it carried out. Where there is a mushroom-house or empty shed in which mushrooms may be grown_, there would be less occasion to pursue it, but there are many places in which no such conveniences exist. In any case it is desirable that gardeners generally should know to what a large extent this phase of the culture is pursued round London and Paris, and how simply it is done. Instead of mats, it would be an improvement to cover the beds with tarpaulin or some other cheap material that would keep out the wet. g2 84 CHAPTER VIII. CULTURE IN GARDENS^ ETC.^ WITH OTHER CROPS IN THE OPEN AIR. This is a phase of culture whicli may be pursued to great advantage in every private garden, almost without cost and attention. The low ridge-like hotbeds, for example, made for both long and short prickly cucumbers, gourds, marrows, &c., are admirably suited for growing a crop of mushrooms under the leaves of the subjects for which they Avere made. If the spawn be inserted soon after the beds are made, or at any convenient time in early summer, the beds will come into bearing in due course. Perhaps they may do so when mushrooms are found abundantly in the fields ; but there are thousands of persons possessing gardens who have no fields in which to cull mushrooms, and who would like to gather them fresh in summer or autumn, if they could not aff'ord to grow them in any covered structure in winter. And this is but one way in which they may be grown with summer garden crops, as will appear from the following commu- nication, by Mr. Ayrcs, to the Field : — CULTURE IN GARDENS, ETC. 85 " The finest crop and the best mushrooms I ever saw were grown in the open ground, and without any protec- tion at all. I will tell you how it happened. Some years back I had the charge of the garden of a noted hunting establishment in Northamptonshire, one of the aids to success being that the manure of an average of nearly fifty higlily-fed horses went to the garden, the owner remarking that, whatever other things I might run short of, there would be plenty of ^ muck.^ Well, the best of the hunters during the summer were soiled in loose boxes, principally under cover, and in these boxes the manure was allowed to accumulate until it began to grow too hot for the feet of the horses ; then it was in- dispensable that it should be removed. About midsummer it so happened that nearly three acres of ground had been cleared of the spring crop, spinach, early peas, beans, &c., and I had determined to devote the whole plot to winter brassicas, broccoli, Brussels sprouts, &c. The ground was brashy and very poor, and consequently I determined to clear the boxes and put the whole of the manure upon it. It was carted away so rich in ammonia that the men who loaded it shed tears, not from sentiment, but from compulsion ; and when the manure was spread upon the surface it was nothing less than a foot thick — so thick, that the proprietor said it was impossible for it to be dug into the ground. However, clearing a trench at one end of the 86 MUSHROOM CULTURE. piece^ thirty inches wide and nearly a foot deep, the subsoil was broken up with strong steel forks,, and upon that the dung covering the next strip was placed, and covered with the surface soil of the next trench; and so the work proceeded until the manure was put out of sight. I may remark that the dung, especially that around the walls, contained evidence of being strongly impregnated with mushroom spawn, though this was not regarded as being likely to produce a crop of the escu- lent. A soaking rain falling, the ground was immediately planted with brassicas, which grew as if they could not help growing — and in fact they could not. '^ We had not planted for mushrooms, nor were mush- rooms expected; but, walking round one morning early in September, a bunch of splendid fellows presented themselves, so large and thick and solid, that when I took them in for breakfast my chef de cuisine and ' better half '' had grave doubts as to whether they were ' the real thing.^ However, they were eaten, and the present writing is a proof that they did not poison me. Return- ing to the plot, I found the bunch gathered was not a solitary one — on the contrary, the ground was literally paved with mushrooms, many of them so large that bushels were gathered for ketchup within a few hours ; while the retainers of a large establishment, down to the lowest labourer, were in a fortnight positively sick of them, and cartloads rotted upon the ground. CULTURE IX GARDENS, ETC. 87 " Tlic evidence of this uucxpected success demoustratcd two thiugs — first, that if the ground is freely manured ■with fresh dung from well-fed horses, mushrooms are almost sure to be produced; and, secondly, that the more the ground is covered with the foliage of plants, the more certain will be the crop. Thus we found more mushrooms under savoys and broccoli than under Brussels sprouts — the former no doubt protecting the crop fi'om heavy drenches of rain, Avhich we know are very injurious to the mushroom crop. Since this example of mushroom- growing turned up, nearly fifteen years ago, I have fre- quently concentrated the fresh manure under a row of savoys or broccoli, throwing in at the same time a dust of mushroom spawn or the dung of a spent mushroom bed ; and, except in very wet seasons, I have rarely failed to have a fine supply during the months of Sep- tember and October. One point of success I believe to be essentially necessary, and that is, that water shall have a free passage through the ground at all times ; hence the necessity of trenching the ground, if you expect mush- rooms as well as brassicas.^' Even in gardens where mushrooms arc well grown in enclosed structures such results in early autumn will often be desirable ; wliilc in numbers of places where there are few or no 0])portunities of gathering them in abundance under other circumstances, crops in the garden will be very welcome. Therefore utilise the old mushroora-bcds I 8S CHAPTER IX. MUSHROOM CULTURE IN PASTURES, ETC. Notwithstanding the extreme abundance of the com- mon mushroom in the meadows and pastures of the British islands, and probably in similar positions all the world over, it is scarce in many situations, and, it may be, not a few persons would be willing to make it of more frequent occurrence in their fields. There is an opinion not uncommon that this cannot be done ; that the mush- room is, to a great extent, a creature of chance, and that it cannot be cultivated. This is not a philosophical notion : there can be no doubt that the mushroom has to abide the results of the struggle for life as well as any other species of plant. Considering that we have taken the sj)awn from the fields and cultivated it with great success in all sorts of positions, none of which it could ever inhabit naturally, it is absurd to suppose that we cannot induce it to grow in positions exactly similar to its native habitat. Found in open, sunny meadows and pastures, and avoiding the shade of trees, it is grown, as we have seen, in dark and deep mines; yet people sup- CULTURE IX PASTURES, ETC. 89 pose it cannot be grown in those pastures in which it happens not to be found. It is erroneously inferred that there is something in its constitution or habit which causes it to occur in certain spots exclusively ; but as well might we say this of any other plant. We know well that hundreds of native plants are hardy enough to grow almost anywhere,, yet how many of them are but locally distributed and rare ! Again^ many plants arc weeds in one district and unknown in another, perhaps, neighbouring one. As the Rev. M. J. Berkeley remarks : — " It is almost useless to advert to the notion, though a very common one, which would regard these productions as the creatures of chance or of a happy concurrence of circumstances favourable to their growth from inorganic elements. It is true they often occur in unexpected situations, and from their extreme rapidity of development seem as if they could not have originated from anything like seed. But, as accurate inquiry has now thrown much light on the mystery in which the origin of intestinal worms was lately involved, so the phenomena which attend the growth of fungi are gra- dually receiving light, and they arc found to follow essentially the same laws as more perfect vegetables.^' It is, in fact, quite fair to conclude that mushrooms, like most other plants, occupy but a small space in the vast expanse of soil and site which are naturally adapted 90 MUSHROOM CULTURE. for their growth. I read in a gardening journal that '^ it is impossible to command a crop of out-door mush- rooms.'''' I am positive that it can be done with almost as much certainty as any other crop^ provided wc take into consideration certain conditions. Of course, we must remember its natural wants ; the more we do so, the more certain of success we may be. We know that it grows most abundantly in rich, upland pastures where water does not lie, associated with the meadow foxtail, meadow and hard fescue and cock^s-foot grasses, clovers, cowslips, daisies, yarrow, &c., and also with the thistles [Cnicus lanceola tus 2ind C. arvensis)) and other plants fond of similar soils. "We know that it is rarely found where the marsh plume-thistle (Cnicus palustris), tufted hair- grass, and other marsh grasses and plants abound, and from the presence or absence of these plants we may easily make up our minds as to the positions that suit it best. Now, it has long since been proved in gardens that it is quite possible to cultivate plants to a much higher degree of perfection than they ever attain in a Avild state, under conditions entirely different, and it is not improbable that we should be able to grow the common mush- room in soils and positions far removed from those in which it naturally occurs. But there is no occasion for anvthincr of the kind. It loves well-drained and drv pastures and meadows, and is not the country covered with such? CULTURE IX PASTURES, ETC. 91 After selecting the position in which we wish to propagate mushrooms^ and no moderately dry pasture- land need be without them, the next thing to consider is the providing of the spawn. Hitherto this has probably been the great difficulty. When nearly 20/. worth of mushroom spawn was annually used in the mushroom-houses of a large garden, the expense neces- sary to spawn a large pasture might well alarm the richest of mushroom-loving landholders; but there is not the slightest occasion for purchasing the spawn for this purpose. Every farmer and country gentleman can make it as easily as_, or more easily than, the spawn-manufacturer, without any-expense or inconvenience, the essential thing being a quantity of rather short stable-manure. Where this is gathered in large heaps it will be easy to obtain the requisite materials at once. Where it is not so, a few loads of stable manure unmixed with long straw may be throAOi together in the open air and prepared for the pui'pose. There is no occasion to place it in a shed of any kind, though if there be one at hand so much the better. If prepared in the open air it should be on a dry place ; the materials should be subjected to exactly the same preparation as when used for making a mushroom-bed, before described. They should be made into a potato- pit-shaped bed, and spawned in the usual manner. For this spawning it is of course necessary to obtain a little spawn, wliethcr home-made or bought from the seeds- 92 MUSHROOM CULTURE. man^ or found in what the French call ^^ a virgin condi- tion^^ in the dunghill. In any case it will not be found difficult to spawn one or more beds in this way, particu- larly as there is nothing to pre^^ent people drying as much home-made spawn at one time as will suffice for a year or more. The spawn should be allowed to run through this bed_, which should be covered with a slight sprinkling of earth_, and beaten pretty firm. When it has penetrated through the bed, it should, just before it arrives at a bearing condition, be ready to be used as spawn. The number of beds to be spawned in this way may be limited according to the extent of ground on which it is proposed to grow the mushrooms. This spawn may be inserted in the meadows in early summer, the most suitable time is in genial weather in May, and the spawn should be inserted in holes from six to ten feet apart. The most expeditious and best way of inserting it is that termed T-planting, striking the spade in the line represented by the perpendicular of the T, and then in the horizontal one on the top, pressing the spade back when in the last position, so as to readily admit of the inser- tion of one or more pieces of spawn. The kind of spawn made as I have recommended usually falls into small pieces, more likely to impregnate the earth quickly than the stijff, brick-like pieces of nursery spawn. The ground, after the insertion of the spawn, should be pressed firm with CULTURE IN PASTURES, ETC. 93 the foot. As to the depth at which the spawn should be deposited, it would be better not to put it at any given depth, but so that while one pieee of a flake may be at a depth of six inches or nearly so, others may touch the very surface. This, it need hardly be pointed out, would allow of the spawn vegetating at the depth and temperature most congenial to it. It would be most desirable to spawn at slightly difi'erent times, and, if pos- sible, with different samples of spawn : thus, for ex- ample, it would be well to use a mixture of old and dried spawn with that taken fresh from one of the beds alluded to. If this were not convenient, some part of the large bed of spawn might be laid by to dry, and used a week or two afterwards. Probably the most economical ■way of doing this on a large scale would be by employing a number of boys, guided by an experienced workman. It is scarcely desirable to attempt the culture in kept lawns, as no matter how suitable these are for it, the appearance of a large crop of mushrooms would have anything but a tendency to beautify the carpet of turf, and would probably become offensive from their odour. The preceding refers to the cultivation of mushrooms in pastures, meadows, &c. There is not the slightest reason why a similar course of culture would not succeed in fields amongst green crops. As large crops of mush- rooms have been produced in gardens under broccoli, &c., there is no reason whatever why they might not be 94 MUSHROOM CULTURE. grown in tlie same manner under field-turnips, mangold- wurtzel, &c. The spawn whicli could be so easily pre- pared by any farmer, could be readily inserted in tbe sides of the drills in which these crops are usually grown^ the slight elevation of which, by preserving the spawn from excessive wet, will favour its development, and it would take possession of, and impregnate the manure in the drill. In fact, prodigious quantities might be raised in this and similar ways, with but little trouble ; and should the fields be afterwards laid down, as is not uncommonly the case, the pasture or meadow would probably become a regular mushroom-ground. 05 CHAPTER X. THE COMMON MUSHROOMS. Agaricus campestris (True ^leadow Musliroom). The common meadow musliroom varies considerably, but, " common to all are a fleshy pileiis, which is some- times smooth, sometimes scaly, in colour white, or of different shades of tawny, fuliginous, or brown ; gills free, at first pallid, then flesh-coloured, then pink, next purple, at length tawny-black ; the stem white, full, firm, varying in shape, furnished with a white persistent ring; the spores brown-black, and a volva which is very fugacious/' — Badham^s Esculent Funguses of England. There is scarcely any one in England avIio does not feel himself competent to decide on the genuineness of a mushroom ; its pink gills easily distinguish it from a kindred fungus, Ag. arvensis, the gills of which arc of a flesh-coloured grey, and out of the pickings often thousand hands, a mistake is of rare occurrence ; and yet no fungus presents itself under such a variety of forms, or such sin- gular diversities of aspect ! The inference is plain ; less discrimination than that employed to distiuguish tliis would enable anvouc who should take the trouble to re- 96 MUSHROOM CULTURE. cognise at a glance many of those esculent species, which every spring and autumn fill our plantations and pastures with plenteousness. Neither is this left to be a mere matter of inference; it is corroborated in a singular manner by what takes place at Rome ; there, whilst many rig. 28.

The spores are magnified 700 diameters. hundred baskets of what we call toadstools are carried home for the table, almost the only one condemned to be thrown into the Tiber, by the inspector of the fungus market, is our own mushroom ; indeed, in such dread is this held in the Papal States, that no one knowingly THE COMMON MUSHROOMS. 97 "would toucli it. '^ It is reckoned one of tlie fiercest imprecations/' writes Professor Sanguinetti, " amongst our lower orders, infamous for the horrible nature of their oaths, to pray that one may die of a Pratiolo ;" and although it has been some years registered among the esculent funguses of Milan and Pavia (on the authority of Yittadini), it has not yet found its way into those markets. Mr. Worthington G. Smith, in his " Mush- rooms and Toad-stools/' qualifies this statement of Dr. Badham. Agancus campestris is not generally appreciated in Italy, and indeed is seldom eaten, and never appears in the markets, for the simple reason that there would be no sale for it. There is an edict in existence ordering certain fungi to be thrown into the Tiber, but it is now, and has long been altogether effete ; and whilst there is an abundance of A. Ccesareus (avowedly the most delicious of all fungi) for the markets of Italy, it is not to be ex- pected the consumption will be given up for another and little knowTi species. The Modes of Cooking this Species. — " The mushroom, having the same proximate principles as meat, requires, like meat, to be cooked before these become changed. The Ag, campestris may be prepared in a great variety of ways : they give a fine flavour to soup, and greatly improve bcef-tca; where arrowroot and weak broths are distasteful to the patient, the simple seasoning H 98 MUSHROOM CULTURE. of a little ketchup will frequently form an agreeable change. Some roast them^ basting with melted butter and white (French) wine sauce. In patties and vols- au-vent they are equally excellent ; in fricassees, as everybody knows_, they are the important element of the dish, Roques recommends in all cases the removal of the gills before dressing, which though it secures a more elegant-looking entremets, is only flattering the eye at the expense of the palate.^^ — Badham, Agaricus arvensis (Horse-Mushroom). '^ Pileus fleshy, obtusely conico-campanulate, then expanded, at first floccose, then smooth, even, or rivulose ; stem hollow, with a floccose pith ; ring broad, pendulous, double, the outer split in rays ; gUls free, wider in front, at first dirty white, then brown, tinged with pink/" — Berkeley's Outlines of British Fungology. '^ This species is very nearly allied to the meadow mushroom, and frequently grows with it, but it is coarser, and has not the delicious flavour. It is usually much larger, often attaining enormous dimensions; it turns a brownish yellow as soon as broken or bruised. The top in good specimens is smooth, and snowy white ; the gills are not the pure pink of the meadow mushroom, but dirty brownish white, ultimately becoming brown- black. It has a big, ragged, floccose ring, and the pithy THE COMMON MUSHROOMS. 90 stem is inclined to be hollow. It is the species exposed for sale in Covent Garden Market. Indeed, after knowing the market for many years_, I have rarely seen any other species there ; when the true mushroom, how- ever, is there, it is frequently mingled with horse mush- Fig. 29. Agaricus arvensis (Horse Mushroom). Pastures, in autumn ; colour, yellowish ; gills pallid, at length black ; diameter, 6 to 24 in. rooms, which seems to show that the dealers do not know one from the other. In the wet days of autumn, children, idlers, and beggars go a few miles from town into the meadows to gather whatever they can find in the mush- room line ; they then bring their dirty stock to market, H 2 100 MUSHROOM CULTURE. "where it is sold to fashionable purchasers ; stale^ vapid, and without taste — unless it be a bad one. ^^ When young and fresh^ the horse mushroom is a most desirable addition to the bill of fare : it yields an abun- dant gravy, and the flesh is firm and delicious. It is a valuable plant when freshly gathered, but when stale it becomes tough and leathery, and without aroma or juice. " There is a curious, large, brown, hairy variety, of rather uncommon occurrence, similar to the hairy variety of the meadow mushroom, the A. villaticus of Dr. Badham. It is a splendid form, but, I think, very rare. I have only seen it once. "Many country-folk readily distinguish the meadow from the horse mushroom, and show antipathy to the latter, although they are always willing to put it into the jar as one of the ingredients of ketchup. Opinions appear to diff'er greatly regarding the excellence of this species. Mr. Penrose writes : — ' I think young, and especially button, specimens of this very indigestible ; until they are well opened out, they are unfit for use.^ Such, however, I must say, is not my experience of button specimens. '^ There is a strong odour attached both to the fungus and the spawn, the ground just below the surface being frequently white with the latter ; or if horse-dung be kicked aside in a rich meadow frequented by gramini- THE COMMON MUSHROOMS. 101 vorous animals, the earth will frequently present a snowy whiteness from the spawn of this species, from which the young individuals may be seen springing up. " I once saw a sheep eat a large specimen with gi'eat apparent gusto, although the fungus was full of maggots/' — Worthington G. Smith. 10; CHAPTER XI. MODES OF COOKING THE COMMON MUSHROOMS. The following modes of cooking mushrooms may prove useful to some : — To Stetv Mushrooms. — Trim and rub clean half a pint of large button mushrooms ; put into a stew-pan two ounces of butter^ shake it over the fire till thoroughly melted; put in the mushrooms_, a tea-spoonful of salt, half as much pepper, and a blade of mace pounded ; stew till the mushrooms are tender, then serve them on a hot dish. They are usually sent in as a breakfast dish, thus prepared in butter. Mushrooms a la Crime. — Trim and rub half a pint of button mushrooms, dissolve two ounces of butter rolled in flour in a stew-pan ; then put in the mushrooms, a bunch of parsley, a tea-spoonful of salt, half a tea-spoonful each of white pepj)er and of powdered sugar, shake the pan round for ten minutes, then beat up the yolks of two eggs, ^\\i\\ two table- spoonfuls of cream, and add by degrees to the mushrooms ; in two or three minutes you can serve them in the sauce. MODES OF COOKING THE MUSHROOM. 103 Mushrooms on Toast. — Put a pint of mushrooms into a stew-pan^ with two ounces of butter rolled in flour ; add a tea- spoonful of salt, half a tea-spoonful of white pepper, a blade of mace powdered, and half a tea-spoonful of grated lemon ; stew till the butter is all absorbed, then add as much white roux as will moisten the mushrooms; fry a slice of bread in butter, to fit the dish, and as soon as the mushrooms are tender serve them on the toast. To Pot Mushrooms. — The small open mushrooms suit best for potting. Trim and rub them ; put into a stew- pan a quart of mushrooms, three ounces of butter, two tea-spoonfuls of salt, and half a tea-spoonful of Cayenne and mace mixed, and stew for ten or fifteen minutes, or till the muslirooms are tender ; take them carefully out and drain them perfectly on a sloping dish, and when cold press them into small pots, and pour clarified butter over them, in which state they will keep for a week or two. If required to be longer preserved, put writing paper over the butter, and over that melted suet, which will effectually preserve them for many weeks, if kept in a dry, cool place. To Pickle Mushrooms. — Select a number of small, sound, pasture mushrooms as nearly as possible alike in size ; throw them for a few minutes into cold water ; then drain them ; cut off the stalks, and gently rub off the outer skin with a moist flannel dipped in salt ; then boil the vinegar, adding to each quart two ounces of salt, 104 MUSHROOM CULTURE. half a nutmeg sliced^ a drachm of mace^ and an ounce of white pepper-corns ; put the mushrooms into the vinegar for ten minutes over the fire ; then pour the whole into small jars^ taking care that the spices are equally divided; let them stand a day, then cover them. Another Method. — In pickling mushrooms take the buttons only and while they are quite close, cut the stem off even with the gills and rub them quite clean. Lay them in salt and water for forty- eight hours, and then add pepper, and vinegar in which black pepper and a little mace have been boiled. The vinegar must be applied cold. So pickled they will keep for years. Mushrooms en Ragout. — Put into a stew-pan a little stock, a small quantity of vinegar, parsley, and green onions chopped up, salt, and spices. When this is about to boil, the mushrooms being cleaned, put them in. When done remove them from the fire, and thicken with yolks of eggs. Mushrooms and Toast. — Peel the mushrooms, and take out the stems. Fry them over a quick fire. When the butter is melted take off the pan. Squeeze the juice of a lemon into it. Let the mushrooms fry again for some minutes. Add salt, pepper, spices, and a spoonful of water, in which a clove of garlic, having been cut into pieces, has soaked for half an hour ; let it stew. When the mushrooms are done, make a thickening of MODES OF COOKING THE MUSHROOM. 105 yolks of eggs. Pour the muslirooms on bread fried in butter, and laid in the dish ready for them. Mushrooms en Caisse. — Peel the mushrooms lightly, and cut them into pieces. Put them into cases of buttered paper, with a bit of butter, parsley, green onions, and shalots chopped up, salt and pepper. Dress them on the gridiron over a gentle fire, and serve in the cases. Mushrooms a la Provencale. — Take mushrooms of good size. Remove the stems, and soak them in olive oil. Cut up the stems with a clove of garlic and some parsley. Add meat of sausages, and two yolks of eggs to unite them. Dish the mushrooms, and garnish them with the forcemeat. Sprinkle them with fine oil, and dress them in an oven, or in a four de campafjne. Baked Mushrooms. — Peel the tops of twenty mush- rooms ; cut off a portion of the stalks, and wipe them carefully with a piece of flannel dipped in salt. Lay the mushrooms in a tin dish, put a small piece of butter on the top of each, and season them with pepper and salt. Set the dish in the oven, and bake them from twenty minutes to half an hour. When done, arrange them high in the centre of a very hot dish, pour the sauce round them, and serve quickly, and as hot as you possibly can. Mushrooms au Gratin. — Take twelve large mushrooms about two inches in diameter, pare the stalks, wash, and drain the mushrooms on a cloth; cut off and chop the stalks. 106 MUSHROOM CULTURE. Put in a quart stew-pan an ounceof butter and half an ounce of flour ; stir over tlie fire for two minutes ; then add one pint of broth ; stir till reduced to half the quantity. Drain the chopped stalks of the mushrooms thoroughly in a cloth ; put them in the sauce with three table-spoonfuls of chopped and washed parsley^ one table-spoonful of chopped and washed shalot_, two pinches of salt^ a small pinch of pepper ; reduce on a brisk fire for eight minutes, put two table-spoonfuls of oil in a saute pan ; set the mush- rooms in, the hollow part upwards ; fill them with the fine herbs, and sprinkle over them lightly a table-spoonful of raspings; put in a brisk oven for ten minutes, and serve. Mushroom Soup. — Take a good quantity of mushrooms, cut ofi* the earthy end, and pick and wash them. Stew them with some butter, pepper, and salt in a little good stock till tender; take them out, and chop them up quite small ; prepare a good stock as for any other soup, and add it to the mushrooms and the liquor they have been stewed in. Boil all together, and serve. If white soup be desired, use the white button mushrooms, and a good veal stock, adding a spoonful of cream or a little milk, as the colour may require. The following ^' family receipts'^ have been commu- nicated by a friend : Clean a dozen or so of medium-sized, place two or three ounces of nice clean beef-dripping in the frying-pan, MODES OF COOKING THE MUSHROOM. 107 and with it a table-spoonful or more of nice beef gravy. Set the pan on a gentle fire^ and as the dripping melts place in the mushrooms, adding salt and pepper to taste. In a few minutes they will be cooked, and being soaked in the gravy and served upon a hot plate, will form a capital dish. In the absence of grav}^_, a soupcon of " extractum carnis^'' may be substituted. Mushrooms with Bacon. — Take some full-grown mush- rooms, and having cleaned them, procure a few rashers of nice streaky bacon, and fry it in the usual manner. "When nearly done, add a dozen or so of mushrooms, and fry them slowly until they arc cooked. In this process they will absorb all the fat of the bacon, and with the addition of a little salt and pepper, will form a most ap- petising breakfast relish. Mushroom Stems, if young and fresh, make a capital dish for those who arc not privileged to eat the mushrooms. Rub them quite clean, and after washing them in salt and water, slice them to the thickness of a shilling, then place them in a saucepan with sufficient milk to stew them tender; throw in a piece of butter and some flour for thickening, and salt and pepper to taste. Serve upon a toast of bread, in a hot dish, and add sippets of toasted bread. This makes a light and very delicate supper dish, and is not bad sauce to a boiled fowl. 108 CHAPTER XII. SOME OF THE MOST COMMON AND USEFUL EDTBLE FUNGI. " Whole hundredweights of rich, wholesome diet rotting under the trees; woods teeming with food, and not one hand to gather it; and this, perhaps, in the midst of potato-blight, poverty, and all manner of privations, and public prayers against imminent famine." Dr. Badham. Valuable as is the common mushroom,, it is indispu- table that not a few other kinds are also capable of af- fording excellent food. Therefore, figures are given of the most prevalent, useful, and easily recognised kinds of edible fungi, as well as of the common mushrooms of our gardens and markets. These figures have been admirably- drawn by Mr. W. G. Smith, and are accompanied by what seemed the most satisfactory accounts of the characters and properties that are obtainable. The spores which accompany the figures are uniformly enlarged seven hundred diameters. Marasmius oreades (Fairy-ring Champignon). Pileus smooth, fleshy, convex, subumbonate, generally more or less compressed, tough, coriaceous, elastic, wrinkled ; when water- soaked, brown ; when dry, of a EDIBLE FUNGI. 109 buff or cream-colour, the umbo often remaining red- brown, as if scorched ; gills free, distant, ventricose, of the same tint as the pileus, but more pale ; stem equal, solid, twisted, very tough and fibrous, of a pale silky- white colour. Fig. 30— 1. ilfa;'a*miM5oreac?e5 (Fairy-ring Champignon). Pastures, roadsides, and downs, in the autumn; colour, pale buff; gills broad and far apart ; diameter, 1 to 2 inches. Fig. 30 — 2. Marasmius urens (False Champignon). Woods and pas- tures in the autumn; colour, pale buff ; gills narroto and croivded together ; diameter, \ inch to 1^ inches., The fairy-ring agaric is a valuable little fungus, and common on almost every lawn. In hilly pastures it 110 MUSHROOM CULTURE. generally appears in broad brown patches^ either circular or forming a portion of a circle. M, wrens, the most acrid of all allied funguses^ usually grows in woods^ though sometimes in the fairy-ring. However, its flat top and narrow crowded gills cause it to be readily distinguished anywhere. Opinions on the Merits of Marasmius oreades as an edible Fungus. — '^ On the Continent this species has long been considered edible, but on account of its coriaceous texture it is dried and employed in the form of powder, to season various made-dishes.^^ — Dr. Greville, ^^ The common fairy-ring champignon is the best of all our funguses, yet there is scarcely one person in a thousand who dare venture to use it. "With common observation no mistake need be made with regard to it. It has an extremely fine flavour, and makes perhaps the very best ketchup that there is.''^ — Rev. M. J. Berkeley, '^ An excellent flavour, as good as that of most fun- guses."— Dr. Badham. Modes of Cooking Marasmius oreades. — General Use. — " Cut in small pieces and seasoned it makes an ex- cellent addition to stews, hashes, or fried meats, but it should only be added a few minutes before serving, as the aroma is dissipated by over cooking. It is the mushroom used in the Frencli a la mode beef-shops in London." — Dr. Badham. EDIBLE FUNGI. Ill "When stewed, the champignons require rather longer time to ensure their being made perfectly tender. They are readily dried by removing the stems from the fungus, threading them on a string, and hanging them up in a dry airy place. ^' When dried, it may be kept for years without losing any of its aroma or goodness, which, on the contrary, becomes improved by the process, so as, in fact, to impart more flavour to the dish than would have been imparted by the fresh fungus ; though it is not to be denied that the flesh then becomes coriaceous (or tough), and less easy of digestion.^"' — Dr. Badham. Champignon Powder. — Put the champignons in a stew- pan with a little mace and a few cloves, and a sprinkling of white pepper. Simmer, and shake constantly to pre- vent burning, until any liquor that may exude is dried up again. Dry thoroughly in a warm oven until they will easily powder. Put the dried agaric, or the powder, into wide-mouthed glass bottles, and store in a dry place. It will keep any length of time. A tea-spoonful added to any soup, or gravy, or sauce, just before the last boil is given, will produce a very fine mushroom flavour. Pickled Champignons. — Collect fresh buttons of the fairy-ring agaric and use them at once. Cut oft' the stems quite close and throw each one as you do so into a basin of water in which a spoonful of salt has been put. Drain them from it quickly afterwards, and place them on a soft cloth to dry. For each quart of buttons thus 112 MUSHROOM CULTURE. prepared, take nearly a quart of pale wMte wine vinegar, and add to it a heaped tea-spoonful of salt, half an ounce of whole white pepper, an ounce of ginger-root bruised, two large blades of mace, and a fourth of a salt-spoon of cayenne pepper tied in a small piece of muslin. When this pickle boils throw in the agarics and boil them in it over a clear fire moderately fast, from six to nine minutes. When tolerably tender put them into warm wide-mouthed bottles, and divide the spice equally amongst them. When perfectly cold, cork well, or tie skins and paper over them. Store in a dry place, and keep out the frost. Full-sized champignons may be pickled exactly in the same way, but will require longer boiling, until indeed they become tender. — Modified from Miss Acton. Champignons quickly Pickled. — Place the prepared buttons in bottles with a blade of mace, a tea-spoonful of pepper-corns, and a tea- spoonful of mustard seed in each, and cover with the strongest white wine pickling vinegar boiling hot. Cork or tie down as before, but do not expect them to keep above three months. EDIBLE FUNGI. 113 Ay aricus procerus (the Parasol Agaric). Films fleshy^ ovate when young, then campanulate, and afterwards expanded and umbonate (blunt pointed), from three to seven inches across. Cuticle more or less brown, entire over the umbo, but torn into patches, or Fig. 31. Agmncus i^rocerus (Scaly Mushroom). Pastures, &c., in autumn; colour, pale brownish buffj diameter, 5 to 12 inches. scales which become more and more separated as they approach the margin. Flesh white. Gills unconnected with the stem, fixed to a collar on the pileus surrounding its top. Ring persistent, loose on the stem. Stem six or eight inches high, tapering upwards from a pear-like I 114 MUSHROOM CULTURE. bulb at the root, hollow with a loose pith, whitish brown, but more or less variegated with small and close- pressed scales. Whenever an agaric on a long stalky enlarged at the base, presents a dry cuticle more or less scaly, a darker coloured umbonated top, a moveable ring, and white gills, it must be Agaricus procerus, the parasol agaric, and it may be gathered and eaten without fear. When the whitish flesh of this agaric is bruised it shows a light reddish colour. There are but two other agarics that at all resemble it, and both are edible. One about the same size is Agaricus rachodes. It is not generally considered so good in flavour as A, procerus. Mrs. Hussey, however, says plainly, " If Agaricus procerus is the king of edible funguses, Agaricus rachodes is an excellent viceroy.''^ The other is the Agaricus excoriatus, a very much smaller fungus, with a more slender habit, a shorter stem, and no true bulb at the base. This elegant little fungus is also very good eating. The parasol agaric has a very wide range of growth. It is a common fungus, and is in high request all over the Continent. Opinions on the Merits of Agaricus procerus as an Edible Fungus. — " A most excellent mushroom, of a delicate flavour, and it must be considered a most useful species. ^^ — The Rev. M. J. Berkeley, EDIBLE EUNGI. 115 " Were its excellent qualities better known here^ they could not fail to secure it a general reception into our best kitchens, and a frequent place among our side dishes at table." — Dr. Badham. '' If once tried, it must please the most fastidious." — Worthington G. Smith. There can be no question but that, when young and quickly grown, the parasol agaric is a delicious fungus. It has a light and delicate flavour without the heavy richness which belongs to the ordinary field mushroom. The writer has prevailed on many persons to try it ; all without exception have liked it, many have thought it quite equal, and some have proclaimed it superior, to the common mushroom. Modes of Cooking the Agaricus procerus. — Broiled Procerus. — Remove the scales and stalks from the agarics, and broil lightly over a clear fire on both sides for a few minutes ; arrange them on a dish over fresh-made, well-divided toast ; sprinkle with pepper and salt, and put a small piece of butter on each ; set before a brisk fire to melt the butter, and serve up quickly. If the cottager would toast his bacon over the broiled muslirooms, the butter would be saved. Agarics delicately Stewed. — Remove the stalks and scales from young half- grown agarics, and throw each one as you do so into a basin of fresh water slightly acidu- lated with the juice of a lemon, or a little good vinegar. i2 116 MUSHROOM CULTURE. When all are prepared,, remove them from the water, and put them into a stew-pan with a very small piece of fresh butter. Sprinkle with white pepper and salt, and add a little lemon-juice ; cover up closely, and stew for half an hour. Then add a spoonful of flour, with sufficient cream, or cream and milk, until the whole has the thick- ness of cream. Season to taste, and stew again gently until the agarics are perfectly tender. Remove all the butter from the surface, and serve in a hot dish, garnished with slices of lemon. A little mace, nutmeg, or ketchup may be added ; but there are those who think that spice spoils the mushroom flavour. Cottager's Procerus Pie. — Cut fresh agarics in small pieces, and cover the bottom of a pie-dish. Pepper, salt, and place them on small shreds of fresh bacon, then put in a layer of mashed potatoes, and so fill the dish, layer by layer, with a cover of mashed potatoes for the crust. Bake well for half an hour, and brown before a quick fire. A la ProvenqaJe. — ^^ Steep for two hours in some salt, pepper, and a little garlic ; then toss in a small stew-pan over a brisk fire, with parsley chopped, and a little lemon- iuice.^^ — Dr. Badliam. Agaric Ketchup. — Place agarics of as large a size as you can procure, but which are not worm-eaten, layer by layer, in a deep pan, sprinkling each layer as it is put in with a little salt. The next day stir them well up EDIBLE FUNGI. 117 several times, so as to mash and extract their juice. On the third day strain off the liquor,, measure, and boil for ten minutes, and then to every pint of the liquor add half an ounce of black pepper, a quarter of an ounce of bruised ginger-root, a blade of mace, a clove or two, and a tea-spoonful of mustard- seed. Boil again for half an hour ; put in two or three bay leaves, and set aside till quite cold. Pass through a strainer, and bottle; cork well, and dip the ends in resin. A very little Chili vinegar is an improvement, and some add a glass of port wine, or a glass of strong ale to every bottle. Care should be taken that the spice is not added so abundantly as to overpower the true flavour of the agaric. A careful cook will keep back a little of the simple boiled liquor to guard against this danger : a good one will always avoid it. ^' Doctors weigh their things,^' said a capital cook, " but I go by taste.^^ But then, like poets, good cooks of this order must be born so ; they are not to be made. Coprinus comatus (the Maned Agaric). Pileus cylindrical, obtuse, campanulate, fleshy in the centre, but very thin towards the margin. The external surface soon torn up into fleecy scales, with the exception of a cap at the top. Gills free, linear, and crowded. Quite white when young, becoming rose-coloured, sepia, 118 MUSHROOM CULTURE. and then black, from tlie margin upwards. They then expand quickly, curl up in slireds, and deliquesce into a black inky fluid which stains the ground. Stem of a pure white, four to live inches high, contracting at the top, and bulbous at the base; hollow, fibrillose, stuffed Fig. 32. Coprinus comatus (Maned Mushroom). Pastures, parks, and roadsides, summer and autumn ; colour, snow-white ; height, 5 to 12 inches. with a light cottony web. The bulb is solid and rooting, the ring is movable. This very elegant agaric has also been called Ag. cy- lindricuSj Schceff; Ag. typhoides, Bull ; and Ag.fimetarius, Bolt. It is common throughout the summer and autumn EDIBLE FUNGI. 119 monthsj on road-sides^ pastures, and waste places. It is extremely variable in size. Its general appearance is so distinct and striking, that it cannot possibly be mistaken for any other agaric. It grows so abundantly on waste ground in the dwellings and farm-yards that it may be, says Dr. Bull, called the ^' agaric of civilization /' and for both these reasons it is most valuable as an edible agaric. If its merits were known, it would be eaten as freely as the common field mushroom. " The maned mushrooms,^^ Miss Plues has well said, '' grow in dense clusters, each young plant like an at- tenuated e^^y white and smooth. Presently some exceed the others in rapidity of growth, and their heads get above the ground, the stem elongates rapidly, the ring falls loosely round the stem, the margin of the pileus enlarges, and the oval head assumes a beU-shape ; then a faint tint of brown spreads universally or in blotches over the upper part of the pileus, and the whiteness of its gills changes to a dull pink. A few more hours and the even head of the pileus has split in a dozen places, the sections curl back, melt out of all form into an inky fluid, and on the morrow^s dawn a black stain on the ground will be all that remains. And so on with the others in succession.'^ Opinions on the Merits of Coprinus comatus as an Edible Fungus. — " Esculent when young." — Berkeley. " Young specimens should be selected.'^ — Baclham, 120 MUSHROOM CULTURE. " No despicable dish_, though perhaps not quite equal to the common mushroom/'' — M, C. Cooke. '' If I had my choice^ I think there is no species I should prefer before this one : it is singularly rich^ tender, and delicious/'' — Worthington G, Smith. Dr. M^Cullough, Dr. Chapman^, Elmes Y. Steele, Esq., and some other members of the Woolhope Club, hold Mr. W. G. Smithes opinion as the result of considerable experience. It must be noted, however, that when too young this agaric is rather deficient in flavour, and its fibres tenacious. Its flavour is most rich, and its texture most delicate when the gills show the pink colour with sepia margins. Modes of Cooking the Coprinus comatus. — The best and simplest method is to broil it and serve on toast in the ordinary way. It may be added also with great advantage to steaks and made-dishes, to give flavour and gravy. Comatus Soup. — Take two quarts of Avhite stock, and put in a large plateful of the maned agaric roughly broken out; stew until tender; pulp through a fine sieve ; add pepper and salt to taste ; boil and serve up hot. Two or three table-spoonfuls of cream will be a great improvement. The agarics for this soup should be young, in order to keep its colour light and good. The maned agaric is recommended on all sides for making ketchup, but EDIBLE FUXGI. 121 here^ alsOj it should be quickly used^ and tlie ketchup quickly made. Agaricus gambosus (the True St. Gcorge^s Mushroom) . Pileus thick and fleshy, convex at first, often lobed, be- coming undulated and irregular, expanding unequally ; the margin more or less involute, and at first flocculose ; from three to four inches across ; of a light yellow colour in the centre, fading to almost opaque white at the edges ; it is soft to the touch ; more or less tuberculated, and often presenting cracks. Gills yellowish-white, watery, narrow, marginate, annexed to the stem with a little tooth : they are very numerous and irregular, with many smaller ones interposed, " lying over each other like the plaits of a frilP (from 5 to 11, Vittadini). Steiii firm, solid and white, swelling at the base in young specimens ; but in older ones, though usually bulging, they are fre- quently of even size, and when in long grass they occasionally even taper downwards. This agaric is usually nearly white, smooth, soft, and firm, like kid leather to the touch, and, as Berkeley has happily said, " in ap- pearance it very closely resembles a cracknel biscuit." They grow in rings ; have a strong smell, and appear about St. George's Day (April 23), after the rains which usually fall about the third week in April. They con- 122 MUSHROOM CULTURE. tinue to appear for three or four weeks,, according to the peculiarities of the season. They are usually to be found on hilly pastures in woodland districts. The St. George^s mushroom cannot well be mistaken for any other. The fact of its appearance at this early season^ and growing so freely in rings^ when so very few Fig. 33. Agaricus ffamhosus {St. George's Mushroom). Pastures, in the spring ; colour, cream ; diameter, 4 to 6 inches. other funguses are to be found, is almost enough to dis- tinguish it. It has, however, very distinctive characters in itself in the thickness of its pileus ; the narrowness of its gills, which arc very closely crowded together ; and the solid bulging stem. EDIBLE FUNGI. 123 The St. George's mushroom is not au uncommon agaric in this country, and where it does appear it is usually plentiful — a single ring affording generally a good basket full. It should be gathered when young, or it will be found grub-eaten, for no fungus is more speedily and more voraciously attacked by insects than this one. Opinions on the Merits of Agaricus gambosus as an Edible Fungus. — ^' This rare and most delicious agaric, the mouceron of Bulliard, and the Agaricus prunulus of other authors, abounds on the hills above the valley of Stafora, near Bobbio, where it is called Spinaroli, and is in great request ; the country people eat it fresh in a variety of ways, or they dry and sell it at from twelve to sixteen francs a pound.'' — Letter from Professor Balbi to Persoon, " The most savoury fungus with which I am ac- quainted . . . and which is justly considered over almost the whole continent of Europe as the ne plus ultra of culinary friandise.^' The prunulus (gambosus) is much prized in the Roman market, where it easily fetches, when fresh, thirty baiocchi — i.e., fifteen pence per pound — a large sum for any luxury in Rome. It is sent in little baskets as presents to patrons, fees to medical men, and bribes to Roman lawyers." — Dr. Baclham. The Agaricus gambosus " is one that a person cannot well make any mistake about. It sometimes attains a 124 MUSHROOM CULTURE. large size,, is excellent in flavour^ and particularly -whole- some/''— Rev. M. J. Berkeley. Mode of Cooking Agaricus gambosus. — " The best mode of cooking Agaricus gambosus is either to mince or fricassee it with any sort of meat, or in a voU au-vent, the flavour of which it greatly improves ; or simply prepared with salt^ pepper, and a small piece of bacon, lard, or butter, to prevent burning, it constitutes of itself an excellent dish/^ — Dr. Badham. ^^ Served with white sauce, it is a capital appendage to roast veal/^ — Edivin Lees. It may be broiled, stewed, or baked. Breakfast Agaric. — Place some fresh-made toast, nicely divided, on a dish, and put the agarics upon it; pepper, salt, and put a small piece of butter on each ; then pour on each one a tea-spoonful of milk or cream, and add a single clove to the whole dish. Place a bell-glass, or inverted basin, over the whole ; bake twenty minutes, and serve up without removing the glass until it comes to the table, so as to preserve the heat and the aroma, which, on lifting the cover, will be diffused through the room. It dries very readily when divided into pieces, and retains most of its excellence. A few pieces added to soups, gravies, or made- dishes, give a delicious flavour.

It is very common all through the summer and autumn months ; indeed, one of the most abundant mushrooms ; " and it is one of those species that a person with the slightest powers of discrimination may distinguish accu- rately from others.'^ — Badham. Opinions on the Merits of Agaricus rubescens as an Edible Fungus. — " A very delicate fungus, which grows in sufficient abundance to render it of importance in a culinary point of view.^^ — Badham. i( From long experience I can vouch for its being not only wholesome, but, as Dr. Badham says, * a very delicate fungus.^ ^' — F. Currey, Editor of Dr. Badham^'s ^' Esculent Eunguses.^' Modes of Cooking the Agaricus rubescens. — It may be toasted, boiled, or stewed in the ordinary way. Fried Rubescens. — Place the full-grown agarics in water for ten minutes, then drain, and having removed the warty skin, fry with butter, pepper, and salt. The ketch- up made from Agaricus rubescens is rich and good. '^ As it grows freely, and attains a considerable size, it is very suitable for that purpose, qiiantity being a great desideratum in ketchup-making." — Plues, EDIBLE FUNGI. 127 Agaricus nebularis (Cloiicled Mushroom).

Stem from two to four inches long, from a quarter of an inch to an inch thick ; incurved at the base ; not rooting, but attaching by means of a floccose down round its lower portion and for one-third of its length, a large quantity of dead leaves, by which the plant is held erect ; subequal, more or less marked with longitu- dinal pits, firm externally, within of a softer substance. The odour strong, like that of curd cheese.^' — Badham. " Common in certain places, but very rare near London. This species comes up late in the autumn on dead leaves in moist places, principally on the borders of woods. The gastronomic excellences of this species are well known. When gathered, it has a wholesome and powerful odour ; and when cooked, the firm and fragrant flesh has a particularly agreeable and palatable taste.''— -^. G. Smith. " The Ayaricus nebularis requires but little cooking ; a few minutes' broiling {a la Maintenon is best), with butter, pepper, and salt, is sufficient. It may also be delicately fried with bread crumbs, or stewed in white sauce. The flesh of this mushroom is perhaps lighter of digestion than that of any other." — Badham, EDIBLE FUNGI. 129 Lact alius deliciosus (Orange-milk Musliroom). Films smooth, fleshy, umbilicate, of a dull rufous orange, turning pallid from exposure to light and air, but zoned with concentric circles of a brighter hue ; Fig. 36. Lactarius deliciosus (Orange-milk Mushroom). Under fir- trees, in autumn ; colour, brown-orange ; milk at first orange, then green; diameter, 3 to 10 inches. margin smooth, at first involute, and then becoming ex- panded ; from tlirce to five inches across. Flesh firm, full of orange-red milk, which turns green on exposure to the air, as does any part of the plant wlien bruised. K 130 MUSHROOM CULTURE. Gills cleciirrent, narrow^, each dividing into twp^ three several times from the stem to the edge of the pileus ; of a dull yellow by reflected light,, but being translucent, the red milk shines brightly through them. Stem from one to thi'ee inches high;, slightly bent and tapering downwards ; solid, becoming more or less hollow with age ; short hairs at the base ; sometimes pitted (scrobi- culate) . There is no possibility of mistaking this fungus. It is the only one which has orange-red milky and which turns green lohen bruised. These properties distinguish it at once from Lactarius torminosus or necatorj the only fungus which in any way resembles it. This acrid fungus {Lactarius torminosus) is somewhat similar in shape and size, and is also zoned. But the involute edges of the pileus are bearded with close hairs. It is of a much paler colour, and with gills of a dirty white. The milk, also, is white, acrid, and unchangeable in colour. The Orange-milk agaric chiefly affects the Scotch fir- tree, and is generally to be found beneath the drip of the branches around the tree. It is also found in hedge- rows occasionally, but is most abundant in plantations of Scotch fir or larch. Opinions on the Merits of Lactarius deliciosus as an Edible Fungus. — " This is one of the best agarics with which I am acquainted, fully deserving both its name EDIBLE FUNGI. 131 and the estimation in wliicli it is held abroad. It reminds me of tender lambs'* kidneys.'''' — Dr. Badham. " Very luseious eating, full of rich gra\y, with a little of the flavour of mussels/^ — Sowerby. " Cook them well^ and you will have something better than kidneys, which they much resemble both in flavour and consistence.^^ — Mrs. Hussey. Modes of Cooking Ladarius deliciosus. — " The rich gravy it produces is its chief characteristic, and hence it commends itself to make a rich gravy sauce, or as an ingredient in soups. It requires delicate cooking, for though fleshy it becomes tough if kept on the fire till all the juice is exuded. Baking is perhaps the best process for this agaric to pass through. It should be dressed when fresh and pulpy.^^ — Edwin Lees. Stewed Deliciosus. — " The tourtiere (or pie-dish) method 'of cooking suits Lactarius deliciosus best, as it is firm and crisp in substance. Be careful to use only sound specimens. Reduce them by cutting across to one uniform bulk. Place the pieces in a pie-dish, with a little pepper and salt, and a small piece of butter on each side of every slice. Tie a paper over the dish, and bake gently for three-quarters of an hour. Serve them up in tjie same hot dish." — Mrs. Hussey. Deliciosus Pie. — Pepper and salt slices of the agaric, and place tliem in layers with thin slices of fresh K 2 132 MUSHROOM CULTURE. bacon, until a small pie-dish is full ; cover with a crust of pastry or mashed potatoes, and bake gently for three- quarters of an hour. If with potato crust, brown nicely before a quick fire. Deliciosus Pudding. — Cut the agaric into small pieces ; add similar pieces of bacon, pepper, and salt, and a little garlic or spice; surround with crust, and boil three- quarters of an hour. Fried Deliciosus. — Fry in slices, properly seasoned with butter, or bacon and gravy ; and serve up hot with sippets of toast. A steak in addition is a great im- provement. Morchella esculent a (the Morel). Every one knows the Morel — that expensive luxury which the rich are content to procure at great cost from our Italian warehouses, and the poor are fain to do with- out. It is less generally known that this fungus, though by no means so common with us as some others (a cir- cumstance partly attributable to the prevailing ignorance as to when and where to look for it, or even of its being indigenous to England), occurs not unfrequently in our orchards and woods, towards the beginning of summer. Roques reports favourably of some specimens sent to him by the Duke of Athol ; and others, from different parts of the country, occasionally find their way into Covent EDIBLE FUNGI. 133 Garden Market. The genus Morchella comprises very few species, and they are all good to eat. Persoon remarks, that though the Morel rarely appears in a sandy soil, preferring a calcareous or argillaceous ground, it frequently springs up on sites where charcoal has been burnt, or where cinders have been thrown. Fig. 37. Morchella esrulenla (the Morel). Woods, &.c., in the spring; colour, pale buff; height, 3 to 5 inches. Pileus very various in shape and hue, the surface broken-up into very little cells, made by folds or plaits of the hymenium, which are more or less salient, and constitute the so-called ribs. These ribs are very irre- gular, and anastomose with each other throughout ; the 134 MUSHROOM CULTURE. pileus hollow, opening into the irregular stem. Spores pale yellow. Neither of these funguses should be gathered after rain, as they are then insipid and soon spoil. ^^ M. Koques says the Morel may be dressed in a variety of ways, both fresh and dry, with butter or in oil, au gras or a la creme. The following receipts for cook- ing them are from Persoon. 1st. Having washed and cleansed them from the earth which is apt to collect between the plaits, dry thoroughly in a napkin, and put them into a saucepan with pepper, salt, and parsley, adding or not a piece of ham ; stew for an hour, pouring in occasionally a little broth to prevent burning ; when sufficiently done, bind with the yolk of two or three eggs, and serve on buttered toast. 2nd. Morelles a ritalienne. — Having washed and dried, divide them across, put them on the fire with some parsley, scallion, chervil, burnet, tarragon, chives, a little salt, and two spoonfuls of fine oil. Stew till the juice runs out, then thicken with a little flour; serve with bread-crumbs and a squeeze of lemon. 3rd. Stuffed Morels. — Choose the freshest and whitest morels, open the stalk at the bot- tom, wash and wipe them well, fill with veal stuffing, anchovy, or any icich. farce you please, securing the ends, and dressing between thin slices of bacon ; serve with a sauce like the last.^^ — Badham, EDIBLE FUNGI. 135 Hygrophorus pratensis.

" Pileus fleshy, convexo-plane, obtuse, moist, at length areolato-rimose ; stem stufifecl, Arm, short, attenuated at the base; gills decurrent, distant, rather thick .^^ — Grev, 1. 166. " On downs and short pastures. Extremely common. Mostly pure ivory-white.^^ — Berkeley. This species, exquisite in form and flavour, is one of the prettiest ornaments of our lawns, downs, and short pastures at the fall of the year. In these situations it may be found in every part of the kingdom. It is essen- tially waxy J and feels and looks precisely as if made of the purest virgin wax. The stem is firm, stuff'ed, and attenuated, and the gills singularly distant from each other ; it changes colour a little when getting old, at which time it is unfit for culinary purposes. A batch of fresh specimens, broiled or stewed with taste and care, will prove agreeable, succulent, and flavorous eating, and may sometimes be obtained when other species are not forthcoming. ^' Several allied species enjoy the reputation of being esculent, notably H, niveus ; and my friend Mr. F. C. Penrose has eaten, and speaks favourably of H, psittacinus — a highly ornamental yellow species, with a green stem, sometimes common enough in rich pastures (and said to be very suspicious) .^^ — W.
