Agaricaceae 



Hyphoioma. about 8 in. long, 3-4 lines thick, holloiv, attenuated from the thickened 

 base or equal, floe cose- fibrillose , pale rust color or becoming dingy-brown 

 below, with a frosty bloom at the apex; veil hanging from margin of 

 pileus, white. Gills adnate, crowded, at first light yellow-white, at 

 length becoming ash-colored, not deliquescent, and not becoming purple 

 or green. 



Strong smelling, odor acid ; extremely variable in stature ; not hy- 

 grophanous. Fries. 



Spores elliptical, 7x4^ Massee. 



West Virginia, Pennsylvania, New Jersey, North Carolina. On oak, 

 chestnut stumps and growing from tree roots in ground. October to 

 December. Mcllvaine. 



(See H. perplexum, H. sublateritium and compare descriptions.) 



This species, in common with its allies, is extremely hard to deter- 

 mine. When growing singly from roots or from ground heavily charged 

 with decaying wood, it is a sturdy, solid plant; when in clusters the 

 stem is longer, more flexible and the whole character of the plant is 

 modified. Except for botanic purposes there is no occasion to puzzle 

 over it. It is in every way an excellent and useful fungus. 



H. disper'sus Fr. dispcrgo, to scatter. Pileus i-i^ in. broad, 

 tawny-honey-color, not hygrophanous, slightly fleshy, bell-shaped then 

 convex, at length expanded, even, superficially silky round the margin 

 with the veil, or squamulose, otherwise even and smooth. Flesh thin, 

 a little paler than the pileus. Stem 2 in. or a little more long, 2 lines 

 thick, tubed, equal, tense and straight, tough, fibrilloso-silky , somewhat 

 rust-colored, becoming dingy-brown at the base, pale at the apex. 

 Gills adnate, thin, ventricose, broad, 34 lines, crowded, at first pallid- 

 straw color, at length crowded, obsoletely green. Fries. 



Gills broader than H. fascicularis, etc. Solitary, scarcely ever ces- 

 pitose. On pine stumps and the ground. April to November. 



Spores elliptical, 7x3-4^ Massee. 



North Carolina, in pine woods, Curtis; California, H. and M.; West 

 Virginia, Pennsylvania, North Carolina, New Jersey, Mcllvaine. 



Difficult to distinguish from H. fascicularis when growing solitary. 

 Its edible qualities are precisely the same. 



H. elseo'des Fr. Gr. an olive; Gr. eidos, appearance. Pileus
