Porphyrosporae 



Indiana, H. I. Miller; Mt. Gretna, Pa., in great clusters between Hyphoioma. 

 railroad ties and beside track, Mcllvaine. 

 Tender. One of the best. 



H. appendicilla'tum Bull. a small appendage. From the veil ad- 

 hering to margin of pileus. (Plate XCVII, p. 352.) Pileus 2-3 in. 

 broad, date-brown then tawny, becoming pale yellowish when dry, 

 fleshy-membranaceous, thin, ovate then expanded, at length flattened, 

 obtuse, smooth, when dry slightly wrinkled, somewhat sprinkled with 

 atoms. Stem 3 in. long, 2-3 lines thick, fistulose, equal, smooth, 

 white, pruinate at the apex; veil fringing the margin of the pileus, 

 fugacious, white. Gills somewhat adnate, crowded, dry, white then 

 flesh-colored, at length dingy-brown. 



Densely cespitose, very fragile and hygrophanous. Much thinner 

 and more fragile than A. Candolleanus. It may be safely distinguished 

 from species which are nearest to it by the gills being whitish then 

 brownish-flesh color. 



Var. lana'tum, A curious form, densely woolly when young, traces 

 of the woolly coat remaining at the apex when the pileus is fully ex- 

 panded. Sibbertoft. B. and Br., 1876. Stevenson. 



Spores ellipsoid, pellucid, 6-8x3-4^ K.; 4x6/i W.G.S.; elliptical, 

 5x2. 5 p Massee. 



Angora, West Philadelphia, October, November, December, 1897; 

 Haddonfield, N. J., Mt. Gretna, Pa., cespitose and gregarious in woods ' 

 about stumps. Mcllvaine. 



"It is very common and edible." Farlow. 



At Mt. Gretna, Pa., October, 1898, in great abundance. When 

 found it was gregarious in large patches and cespitose on stumps. My 

 identification was confirmed by Professor Peck. 



It dries well, and retains flavor and esculent qualities. Cooked it is 

 among the best. 



H. Candol'leanum Fr. After DeCandolle. Pileus 2-4 in. broad, 

 date-brown then becoming white, the top somewhat yellowish, some- 

 what fleshy, acorn-shaped then bell-shaped, soon convex and at length 

 flattened, obtuse and unequal, smooth, even. Flesh thin, white. Stem 

 3 in. long, 2-4 lines thick, fistulose, solid at the base, somewhat thick- 

 ened, fibrillose, white, striate at the apex; veil in the form of a cortina,
