The species is remarkable for the variability in the color of the 
pileus and in the size of the spores. These vary in the same in- 
dividual. The prevailing color of the pileus is pale yellow. 
GALERA FRAGILIS. 
Pileus submembranous, very fragile, broadly campanulate, 
glabrous, dull flesh color; lamellae ascending, adnate, subdistant, 
dark yellow or subochraceous, becoming ferruginous ; stem slender, 
flexuous, hollow; spores elliptical, .0004 in. long, .0002 broad. 
Pileus 3-5 lines broad; stem 10-15 lines long, .5 line thick. 
Among short grasses in pasture. Kansas. Bartholomew. 
A very small and very fragile plant. 
PSILOCYBE SABULOSA. 
Pileus convex, subumbonate, glabrous, yellow; lamellae broad, 
subdistant, ventricose, adnate, becoming purplish-brown, whitish 
on the edge; stem equal, hollow, pallid or straw-color ; spores el- 
liptical, .0005—.0006 in. long, .0003 broad. Puileus 8-12 lines broad; 
stem I-1.5 in..long, about I line thick. 
Sandy soil in pastures. Kansas. August. Bartholomew. 
The pileus in the dried specimens has a somewhat shining ap- 
pearance. The umbo in some specimens is quite prominent, in 
others it is wholly wanting. The species is quite distinct from 
P. arenulina, which is hygrophanous and has smaller spores. 
PSILOCYBE OBSCURA. 
Pileus thin, convex, hygrophanous, striate, more or less flecked 
or scurfy with a white floccose tomentum, brown or reddish- 
brown; lamellae broad, subdistant, adnate, brown, becoming al- 
most black, white flocculent on the edge; stem slender, hollow, a 
little paler than the pileus, whitish tomentose at the base; spores 
elliptical, .o004-.0005 in. long, .00025-.0003 broad. Pileus 4-9 
lines broad; stem I-1.5 in. long, about I line thick. 
Rich leaf mold in woods, Kansas. August. Bartholomew: 
BOLETUS FISTULOSUS. 
Pileus convex, viscid, glabrous, yellow, the margin at first in- 
curved or involute, flesh yellow; tubes plane or subventricose, 
medium size, round with thin walls, adnate or sometimes de- 
pressed around the stem, yellow; stem rather slender, subequal, 
viscid, glabrous, hollow, yellow, with a white mycelioid tomentum 
a the base; s__ res elliptical, .0005 in. long, .00025 broad. Pileus 
about I in. b, ad; stem 2-4 in. long, about 3 lines thick.
