This fungus is not extremely unpleasant when eaten—like T. sulphureum, but no one will care to eat it. There is nothing in the flavor to recommend it or to inspire a cultivation of taste for it. IV.—SERICEL´LA. Pileus slightly silky, soon smooth, etc. * _Gills broad, rather thick, somewhat distant._ =T. sulphu´reum= Bull.—_sulphur_, brimstone. =Odor= strong, fetid or like gas tar. =Cap= 1–4 in. across, subglobose, then convex and plane, slightly umbonate, sometimes depressed, fleshy, margin at first involute. =Color= dingy or reddish sulphur-yellow, at first silky, becoming smooth or minutely tomentose. =Flesh= thick, yellow. =Gills= rather thick, narrowed behind, emarginate or acutely adnate, sometimes appearing arcuate from shape of cap. =Stem= 2–4 in. long, 3–5 lines thick, equal or slightly bulbous, often curved, smooth striate, sulphur-yellow, stuffed, fibrous or hollow, yellow within, at times having yellow fibrous roots. =Spores= 9–10×5µ _Massee_. Very variable in size. Gregarious, common in mixed woods. West Virginia, 1881. West Philadelphia, 1886. _McIlvaine._ When quite young T. sulphureum is showy and inviting. Its smell is discouraging, its taste forbidding. No amount of cooking removes its unpleasant flavor. I have tried to eat enough of it to test its qualities, but was satisfied after strenuous efforts to mark it INEDIBLE. =T. chrysenteroi´des= Pk.—like gold. =Pileus= fleshy, convex or plane, not at all umbonate, firm, dry, glabrous or slightly silky, _pale-yellow or buff_, becoming dingy with age, the margin sometimes reflexed, _flesh pale-yellow, taste and odor farinaceous_. =Gills= rather close, emarginate, yellowish, becoming dingy or pallid with age, _marked with transverse veinlets along the upper edge_, the interspaces veined. =Stem= equal, firm, _solid_, bare, fibrous-striate, yellowish without and within. =Spores= elliptical, 8–10×5–6µ. =Pileus= 1–2 in. broad. =Stem= 2–3 in. long, 3–4 lines thick. Woods. Lewis and Cattaraugus counties. September. Nearly allied to T. chrysenterum, but separable by the gills, which are somewhat veiny and not free, by the entire absence of an umbo and by its farinaceous odor and taste. _Peck_, 44th Rep. N.Y. State Bot. Frequently found at Angora, and in Woodland Cemetery, West Philadelphia. Edible. Fair flavor and good quality. =T. o´picum= Fr.—uncouth. =Pileus= 1–1½ in. across. =Flesh= rather thin, becoming grayish; convex, then expanded, obtusely-umbonate, at length usually upturned and split, very dry, even at first, then minutely scaly, gray. =Gills= broadly emarginate, ventricose, rather thick, scarcely distant, hoary. =Stem= 2–3 in. long, 2–3 lines thick, equal, fibrillose, becoming almost glabrous, pallid then grayish, stuffed. _Massee._ Among moss, in pine woods, etc. Inodorous. Somewhat resembling T. saponaceum, but distinguished by the absence of smell.
