Murrill: Agaricaceae of Pacific Coast 
217 
This species is closely related to some species of Collybia. The 
eccentric position of the stipe was doubtless due to the peculiar 
situation in which the plant grew. 
Melanoleuca dryophila sp. nov. 
Pileus convex, gibbous, becoming almost expanded, scattered, 
3-10 cm. broad; surface glabrous, viscid when fresh, subshining, 
nearly smooth, whitish, stained with rusty-<brown, margin paler, 
somewhat lobed or irregular ; context white, with farinaceous 
taste and odor ; lamellae deeply sinuate to adnexed, close, narrow, 
plane, white, scarcely changing on drying; spores globose, smooth, 
hyaline, 5-8 /t; stipe cylindric or slightly flattened, scarcely en- 
larged below, glabrous, nearly smooth, whitish or brownish, solid, 
6- 8 cm. long, 1-3 cm. thick. 
Type collected in soil under live oaks at Stanford University, 
California, January 21, 1903, James McMurphy 27. This species 
somewhat resembles M. subpessundata, but differs in several 
important characters. 
Melanoleuca farinacea sp. nov. 
Pileus rather thin but fleshy, convex to expanded, umbonate, 
gregarious to subcespitose, reaching 8 cm. broad; surface white, 
smooth, glabrous, margin entire, concolorous ; context white, with 
strong farinaceous odor ; lamellae sinuate, broad, several times in- 
serted, not crowded, ventricose, white ; spores globose, smooth, 
hyaline, 4.5-6.5/x; stipe bulbous and whitish-mycelioid at the base, 
white, subglabrous, smooth, stuffed or hollow, fleshy, 5-6 cm. 
long, 5-10 mm. thick. 
Type collected in humus in woods near Seattle, Washington, 
October 20-November i, 1911, JV. A. Murrill 644. 
Melanoleuca Harper! sp. nov. 
Pileus broad, rather thin, becoming plane or depressed, grega- 
rious or growing in circles, reaching 10-15 cm. broad; surface 
umbrinous, hygrophanous, not viscid, smooth, glabrous, margin 
entire or slightly lobed, concolorous ; lamellae sinuate, white, not 
spotted, crowded, rather broad, ventricose, usually separating 
from the stipe with age ; spores broadly ellipsoid, smooth, hyaline, 
7- 8 X 4 /A ; stipe very short and thick, bulbous, solid, smooth, 
glabrous, white, about 3-4 cm. long, and 2-3.5 cm. thick.
