Var. _re´pens_ Fr. =Pileus= more fleshy, depressed. =Stem= hollow, compressed, pruinate at the apex, with a _creeping, string-like mycelium_. It is best distinguished by its white, villous, anastomosing, very much branched mycelium which creeps a long distance in a rooting string-like manner. The so-called roots are quite different from the stem, not a prolongation of the stem itself. _Fries._ Clearly a variety of C. platyphylla. C. platyphylla is quite variable, even puzzling. Edible qualities the same. =C. long´ipes= Bull.—_longus_, long; _pes_, a foot. =Pileus= 1–2 in. across, conical then expanded, umbonate, dry, minutely, beautifully velvety. =Color= from pale to date-brown, sometimes umber. =Flesh= white, thin, elastic. =Gills= white, broad, tough, thick, adnexed, distant, ventricose, rounded behind, emarginate. =Stem= 4–6 in. long, 2–4 lines thick, tapering upward, usually densely and minutely velvety like the cap, nearly same color, with a long, tapering root. On much decayed stumps and logs. July to October. Closely resembles C. radicata. It is readily distinguished by its velvety cap and stem. It is more glutinous. =Spores= spheroid, 12µ _Q._ California. Edible. _H. and M._ West Virginia mountains, 1880–1885; Cheltenham, Pa., 1889. _McIlvaine._ Excepting from California, C. longipes has not previously been reported as found in the United States. It is not plentiful in the forests of West Virginia, yet I often found it upon rotting stumps and logs, solitary, but up to a dozen in the same vicinity. It is unmistakable. Its rich yet dull velvety cap and stem and the purity of its gills hold the finder’s admiration. The caps fried or broiled are delicious, resembling in every way those of C. radicata. =C. fu´sipes= Bull.—_fusus_, a spindle; _pes_, a foot. (Plate XXVIII, fig. 4, p. 112.) =Pileus= 1–3 in. broad, _reddish-brown_, becoming pale and also dingy-tan, fleshy, convex then flattened, umbonate (the umbo at length vanishing), even, smooth, dry, here and there broken up in cracks when dry. =Stem= 3 in. and more long, commonly ½ in., but here and there as much as 1 in. broad, _fibrous-stuffed then hollow_, remarkably cartilaginous externally, _swollen, ventricose in the middle, attenuated at both ends_, often twisted, longitudinally _furrowed_, red or reddish-brown, _rooted in a spindle-shaped manner at the base_. =Gills= _annulato-adnexed_ (joined into a ring), soon separating, free, broad, distant, firm, connected by veins, crisped, white then becoming somewhat of the same color as the pileus, often spotted. _Stevenson._ =Spores= 6×3µ _W.G.S._; 4–5×2–4µ _B._ Solitary, gregarious, usually densely clustered on decaying wood, roots, etc. August until after heavy frosts. West Virginia, 1882, _McIlvaine_.
