Fungiculture is the cultivation of fungi such as mushrooms. Cultivating fungi can yield foods, medicine, construction materials and other products.
"Spawn is obtained the most readily and in abundance in parcels of decayed dung and dungy composts; but commonly more plenteously and good in rotten horse stable dung, composed of the short dung and moist litter together, as cleared from the stables, either collected in dung-heaps or formed into hot-beds, composts, &c. when it has remained some months till its fermentation and heat are decreased, and a state of decay and putrefaction brought on. This kind of dung being more adapted to the generation of spawn than any other, is a favourable circumstance, as horse dung is to be every where met with."
"In all decayed dung-heaps and hot-beds, old dungy composts, and well dunged foils, not too wet, or the dung very buttery rotten, you may be successful."
"The best season to find spawn in the greatest plenty and perfection is the Autumn and early part of Winter; for spawn being of a singular temperament, impatient of much wet, or cold, or of being much exposed to the open air, it should be carefully collected for use before it is injured and weakened by the inclemency of the weather; for it is of much importance to have it in full vigour, when it may be directly used in spawning beds, provided it be quite dry; otherwise let it lye by for a few weeks."
"Let it be observed... of the spawn in general, that it must be kept dry till wanted; and if any lumps at first gathering appear wet, spread them in a shady covered place before they are laid up in a house; for it is of much importance to have the spawn perfectly dry when planted."
"No dung answers the purpose so well as that of the horse, the dung and urine of this animal, together with the wet straw litter of the stalls in the stables, being of a hot quality, ferments, and acquires a strong degree of heat of long duration; but as this heat generally proves too violent at first for the growth of vegetables, the dung should always be previously reduced to a proper temperature, by casting it up in an heap, and turning it once or twice in order to evaporate the rank burning steam before its fermentation."
"Let it remain together three or four weeks, according to the quantity and strength of heat, in order that it may meliorate, by discharging the rank obnoxious steam; and if it is turned over once every week, it will still incorporate the parts more effectually, and give an additional vent to the fierce ferment."
"In a week or fortnight after the bed is made it will heat violently, and probably continue for a fortnight or three weeks or more, especially if of a considerable extent, and must on no account be spawned till the violent heat subsides and becomes reduced only to a gentle warmth, otherwise the spawn will be totally destroyed and the whole work to be done over again, and this is often the cause of so many Mushroom beds proving barren, the spawn perishing at the first setting off."
"Great humidity is a certain enemy to Mushroom beds, as it soon exterminates the whole spawny substance."
"In the work of spawning the bed, the utmost precaution must be observed, not to perform it until the great heat has passed off, and left only a very gentle warmth; for the small tender spawny-fibres and minute knots of embryo plants would, by one day's great heat, be totally destroyed."
"My reasons for writing this book are: First, that Mushroom Culture is but little practised in this country compared to the extent to which it ought to be, considering the abundance of the necessary materials... every place in which a gardener and horses are kept should be abundantly supplied with Mushrooms throughout the greater part of the year. Secondly... a simpler and fuller account of it than has yet appeared in the English language is desirable for the unpractised amateur and cultivator. Thirdly, Mushroom Culture is at present confined to a too narrow groove... if the knowledge of how easily and in how many ways they may be grown, apart from the usual mode, were sufficiently spread, it would lead to the production of many times our present supply. Fourthly, [I have] a desire to introduce to this and other countries the system of Mushroom Culture on a very large scale carried on in caverns beneath the environs of Paris, which caverns I visited in 1868."
"In every garden where Mushrooms are grown abundance of spawn may be made. ...by saving the spawn as the Parisian growers do, all expense for this article is abolished."
"The introduction of the Mushroom into our domestic economy in as great a degree as we have it in our power to produce it, would practically be the addition of a new agent in our cuisine, second to none for its delicacy, and unsurpassed for utility. ...every cart of stable-manure produced in this great horse-keeping country may, on its way towards decomposition and replenishing the earth, be made a nidus for furnishing many dishes of them."
"We know that the gills are 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. We can see them clearly enough under the microscope—can see 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 surfaces on which they were born, till the "young mushroom" 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. However, the preparation of the spawn, and the subsequent 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 few 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 most places where horses are kept, opportunities of finding this spawn occur. Its white, filamentous, and downy threads have the odour of mushrooms, and the spawn is, therefore, very easily recognised. 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."
"To preserve 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."
"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."
"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, adding 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."
"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. ...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... It is simply the fine rubbish from the stone breakage moistened, and smoothly and firmly pressed over the beds. ...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."
"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 lower parts of the bed are of no use. If one drenching is not sufficient to moisten the bed properly, another should be given. ...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 watering having been given. In watering old beds one ounce of guano to the gallon of water will prove beneficial."
"Woodlice are the greatest pests the mushroom-grower has to dispose of, and the most effective 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 afford these creatures the interstices they usually retire into... 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 covered with hay or litter, it will be necessary to remove this and allow them time to retreat into their hiding places; and if the beds are made in any position that permits 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. ...the scalding water must not in any case be applied to the surface of the bed. ...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 temperature, and in summer, Mr. Cuthill says, "the maggot" will not breed in a house where the temperature does not exceed 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... The entrance of rats should also be guarded against."
"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 proportion of one part to five of soft water, and adding a wineglassful 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."
"Where there are several beds in bearing, 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."
"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-whited, every surface scraped and washed, and the house freely opened, so as to thoroughly sweeten it."
