Pileus usually not over 1.5 in. across. Often in plenty. Its substance does not cook away as with C. micaceus. It amply repays gathering, being highly flavored. (Plate LXXX_a_.) [Illustration: BOLBITIUS NOBILIS. About two-thirds natural size. ] =B. no´bilis= Pk.—noble. =Pileus= thin, fleshy on the disk, ovate then bell-shaped, smooth, plicate-striate, pale-yellow, the disk tinged with red, the margin at length recurved and splitting. =Gills= subdistant, tapering outwardly, attached, the alternate ones more narrow, pale-yellow with a darker edge. =Stem= long, equal, smooth, striate at the top, hollow, white. =Plant= cespitose, 3–5 in. high. =Pileus= 1 in. broad. =Stem= 1 line thick. Ground in woods. Greig. September. A fine large species, but probably rare. _Peck_, 24th Rep. N.Y. State Bot. I have not seen this species. Figure after Professor Peck. =CREPIDO´TUS= Fr. _Gr_—a slipper. (Plate LXXXI.) [Illustration: CREPIDOTUS MOLLIS. Natural size. ] =Veil= wanting or not manifest. =Pileus= eccentric, lateral or resupinate. =Spores= rust-color. The Crepidoti correspond in shape and habit to the smaller Pleuroti and the Claudopodes, but they are distinguished from both by the rust-color of their spores. These are globose in several species, in others they are elliptical. In some there is a depression on one side which gives them a naviculoid character and causes the spore to appear slightly curved when viewed in a certain position. In consequence of the similarity of several of our species, the character of the spores is of much importance in their identification, and it is unfortunate that European mycologists have so generally neglected to give the spore characters in their descriptions of these fungi. In most of the species the pileus is at first resupinate, but it generally becomes reflexed as it enlarges. It is generally sessile or attached by a mass of white fibrils or tomentum. For this reason it is usually somewhat tomentose or villose about the point of attachment, even in species that are otherwise glabrous. In several species the pileus is moist or hygrophanous and then the thin margin is commonly striatulate. This character is attributed to but one of the dozen or more European species. Their mode of growth is usually gregarious or somewhat loosely imbricated, in consequence of which the pileus, which in most species is white or yellowish, is often stained by the spores, and then it has a rusty, stained or squalid appearance. The species occur especially on old stumps, prostrate trunks and soft much decayed wood in damp, shaded places. _Peck_, 39th Rep. N.Y. State Bot.
