SOME COMMON MUSHROOMS AND HOW TO KNOW THEM 39 
HYPHOLOMA 
The genus Hypholoma belongs to the purple-brown-spored group, 
but differs from Agaricus and Stropharia in the character of the 
veil, which persists as fragments or a silky border on the margin 
of the pileus. In some species the latter is firm and fleshy, in others 
fragile. The margin of the pileus is at first incurved. The stem is 
fleshy and lke Stropharia continuous with the substance of the cap. 
Species of the genus Hypholoma generally occur in clusters or clumps 
at the base of dead stumps, logs, or decayed wood under the ground. 
HYPHOLOMA APPENDICULATUM. (EDIBLE) 
(Fig. 35) 
In this species the cap is rather thin, ovate, then expanded until somewhat 
flattened, dark brown when damp, tawny when dry, slightly wrinkled and 
atomate; the flesh is white; the gills are crowded, Somewhat adnate, white, 
at length purplish brown; the stem is white, hollow, equal, smooth, pruinose 
at the apex; the veil is white, delicate, attached to the margin of the cap for 
a short time, soon disappearing. 
The cap is 2 to 3 inches broad ; the stem is 2 to 8 inches long and 2 to 8 lines thick. 
Specimens of this species may be collected in the late spring, in summer, and 
frequently in the early fall. The plants are fragile and hygrophanous, scat- 
‘tered, clustered, or densely tufted. They grow on rotten logs, stumps, or some- 
times on the ground, arising mostly from rotten wood beneath the surface. 
This species is tender and possesses excellent esculent qualities. Drying and 
preserving for winter use have been recommended, as the flavor is retained to 
a remarkable degree.

HYPHOLOMA SUBLATERITIUM. BRICK-TOP. (SUSPECTED) 
(Fig. 36) 
In this species the cap is conical, becoming almost plane, fleshy, firm, smooth, 
but with fine, silky fibers, brick red, sometimes tawny, margin of lighter color; 
the flesh is white or yellowish; the gills are narrow, crowded, adnate, sometimes
