Mycologia 
has at times been considered only a larger form. It is edible, but 
of only tolerable flavor. 
Inocybe geophylla (Sow.) Quel. 
Common White Inocybe 
Plate 137. Figure 6. X 1 
Pileus fleshy, thin, conic or ovoid becoming expanded, conically 
umbonate, 1.5-2. 5 cm. broad; surface silky-fibrillose, smooth, 
commonly white or whitish, rarely lilac ; lamellae crowded, rather 
broad, ventricose, adnexed, white becoming clay-colored; spores 
ellipsoid, smooth, ochraceous, 8-10 X 4—6 yw. ; cystidia cylindric- 
fusoid, 40-60 X 12-20 /x; stipe equal, firm, stuffed, white, mealy 
at the apex, 2.5-6 cm. long, 2-4 mm. thick. 
This species is common on heavy, wet soil on the shaded banks 
of streams or in low open woods throughout temperate regions. 
It is so different from most species of Inocybe that the beginner is 
usually puzzled in identifying it. Abeautiful pale-lilac variety some- 
times occurs, which Boudier has figured in his plate 125. I have 
found this variety quite abundant in the state of Washington. 
Scleroderma verrucosum (Bull.) Pers. 
Small-warted Scleroderma 
P late 137. Figure 7. X 1 
This rather uncommon species was described and figured in 
Mycologia for January, 1910. The illustration on the plate ac- 
companying the present article is made from younger material, 
and the plants have more purple in them than those represented 
on the former plate. 
Tremella lutescens Pers. 
Common Yellow Tremella 
P late 137. Figure 8. X 1 
Very soft and watery, undulate-gyrose, with entire, naked 
lobes, the clusters sessile, whitish to pale-yellowish, and finally 
luteous, 1-5 cm. broad, leaving a very small residue when dried ; 
spores globose, 12-15 /x. 
This species is widely distributed, occurring commonly on dead
