latter specimens are very much larger than the types, measuring 
in the dry state as much as lo cm. broad with a bulbous stipe 
reaching 6 cm. long and 3.5 cm. thick. The color is also much 
darker and is recorded by the collector as brown. The margin 
in the dried specimens is cjuite conspicuously striate. The typical 
specimens are very closely related to Melanoleiica roseibrunnea, 
but dififer in color and in the shape and closeness of the gills. 
Melanoleuca californica sp. nov. 
Pileus convex to subplane, rather thick at the center, grega- 
rious, reaching 15 cm. broad; surface smooth, glabrous, evidently 
viscid when fresh, bringing up adhering particles of soil, reddish- 
brown at the center, much lighter-colored at the margin, which is 
thin, entire and indexed on drying; context white, rather thick at 
the center, thinning out toward the margin, slightly bitter to the 
taste, odor musty; lamellae quite narrow, less than the thickness 
of the context, sinuate to adnexed, plane, cro-wded, white, scarcely 
changing color on drying; spores broadly ellipsoid, smooth, hy- 
aline, 5-7 X 4-5 ft - ; stipe very long, subequal, smooth, glabrous, 
white, solid, 10-15 reaching 3 cm. thick. 
Type collected under oaks on Jasper Ridge near Stanford 
University, January ii, 1911, James McMurphy 12^. This large 
and handsome species resembles specimens determined as Armil- 
laria subannulata Peck sent to Albany from Claremont, Cali- 
fornia, by Baker. Specimens collected by Oleson at Santa Bar- 
bara, California, apparently belong to this category, but they are 
rather poorly preserved and are not accompanied by notes. 
Melanoleuca collybiiformis sp. nov. 
Pileus broad, thin, convex to plane, drying easily like species 
of Collybia, gibbous, reaching 10 cm. broad; surface dry, smooth, 
glabrous, fulvous at the center, pale-fulvous near the entire, 
smooth margin ; lamellae rather crowded, white, sinuate, the 
edges undulate or somewhat notched ; spores globose or sub- 
globose, smooth, hyaline, conspicuously granular within, about 
3.5^; stipe eccentric, bulbous, rather broad, fleshy, hollow, white, 
radicate, 6 cm. long, 1-2 cm. thick. 
Type collected in humus in a grove at Woodland Park, Seattle.
