Var. B. pratensis.
This differs from the last in the duskier hue of its pileus, which is moreover scaly, and has ragged margins; the gills are ventricose; and the ring, which is subfugacious, is cortinarious, i. e. of a cobweb texture, and reflexed; the stalk is longer than in the last species, and tapers towards the base; the colour of the flesh in this variety is vinous or even sanguine.
Var. C. silvicola.
This differs from the two former in the following particulars; the gills are pallid, taper equally at both ends, and come off at a considerable distance from the stalk, which is surrounded above by a very delicate ring, and is bulbous at the base, the bulb showing traces of the volva.[159]
Var. D. anceps.
Such uncultivated mushrooms as when eaten even in small quantity, produce violent derangement of the stomach and intestinal canal, belong to a variety which, since it grows under hedges, is sometimes called “the hedge mushroom;” this, to which, for distinction’s sake, I have given the name of anceps, is by no means of rare occurrence. In order to discriminate it properly from the wholesome varieties, the first point to notice is its extreme lightness as compared with its bulk, that the gills are of a deeper and of a more lurid red than those of var. edulis, and in age less purple; they are also less deliquescent. The flesh is more tough and not so juicy. The stem, as in the var. silvicola, is curved and bulbous, but also fistulose throughout. The ring complete, firm, broad, reflexed, and persistent; the odour disagreeable, and the taste insipid. The form of the pileus that of an obtuse cone in young specimens; extremely flat in the middle state; and more or less concave in age. It seldom grows solitary. The mushroom proper, like other funguses, should be eaten fresh; a few hours making all the difference between its wholesomeness or unwholesomeness: nor need this surprise us when we consider how many principles enter into its composition, how short is the period of its existence, and how liable it must be to enter into new combinations in consequence. Vauquelin found in its flesh fat, adipocere, osmazome, an animal matter insoluble in alcohol, sugar, fungine, and acetate of potash. What a medley! and what wonder, if the changes induced during decomposition should cause the indigestions suffered by those who have eaten them in this state! 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 soups, and greatly improve beef-tea;—where arrow-root and weak broths are distasteful to the patient, the simple seasoning of a little ketchup will frequently form an agreeable change. Some roast them, basting with melted butter and white (French) wine sauce.[160] 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 entremet, is only flattering the eye at the expense of the palate.
Var. E. bovinus.
This variety differs from the Ag. Georgii and the type of the species in size and other particulars. There are specimens which measure fifteen inches across the pileus, with a stalk of corresponding dimensions. The pileus is shaggy, like that of the Ag. procerus, with epidermic scales, which are at first nearly white, but in fully developed specimens, of a rich tawny colour, like the Polyporus squamosus; and sometimes of a red-brown. The scales more depressed than in Ag. procerus, the gills not ventricose, equal at both ends, separated from the stalk by a fossa or groove which runs round its apex; the stalk solid, attenuated at the very base, but thickened just above it, a slightly vinous hue when bruised; flesh of ring perfect, persistent, and hanging round the stalk like a sheet of thin white kid; into which a number of delicate silver threads may be traced proceeding from the apex of stem. The smell is powerful but agreeable, as also is the flavour; no part of the surface ever turns yellow. This variety is both wholesome and well-flavoured; as it is commonly known by the peasants under the name of the “Ox-Mushroom,” I have called it bovinus.
Receipt I.—“A la Provençale.”
Steep for two hours in oil, with some salt, pepper, and a little garlic: then toss up in a small stewpan over a brisk fire, with parsley chopped and a little lemon-juice.
