NEW SPECIES OF FUNGI. € 
Readily distinguished from its allies by its white color. Leptonia 
assularum B, & C. differs in having an umbonate virgate pileus with 
a dark center. Nolanea delicatulus is a more slender, delicate plant 
with a smoother pileus and not at all umbilicate. 
Psilocybe castanella, 
Pileus thin, at first convex or subconical, then expanded or slightly 
depressed, glabrous, hygrophanous, chestnut-colored or umber-brown 
and striatulate on the margin when moist, pale-alutaceous when dry, 
flesh a little paler than the surface of the pileus ; lamelle close, 
adnate or slightly rounded behind, at first pale-brown, then purplish- 
brown ; stem equal, flexuous, hollow or stuffed with a whitish pith, 
slightly silky-fibrillose, brownish or subrufescent with a white myce- 
lium at the base ; spores purplish-brown, .0003 to .00032 in. long, 
.00016 to .0002 in. broad. 
Plant gregarious or subcespitose, 1 to 2 in. high, pileus 4 to 8 
lines broad, stem .5 to 1 line thick. 
Rich grassy ground by roadsides. Sandlake. June. 
The species appears to be closely allied to Agaricus squalens, 
which may be distinguished by its lurid color, decurrent lamelle 
and ferruginous-brown spores. Moreover its habitat is unlike that 
of our plant. In very wet weather both the pileus and lamelle 
sometimes have a watery-brown appearance, and then the striations 
of the former sometimes extend to the disk, which is rarely slightly 
umbonate. In drying, the moisture first disappears from the center 
of the pileus. The young pileus is usually chestnut-colored, and its 
margin and the stem are adorned with a few whitish fibrils. 
Psilocybe fuscofulva. 
Pileus thin, convex or subcampanulate, subumbonate, glabrous, 
hygrophanous, dark watery-brown and striatulate on the margin 
when moist, subochraceous when dry; lamelle rather broad, mod- 
erately close, adnate, subventricose, purplish-brown ; stem slender, 
flexuous, stuffed, slightly silky, reddish-brown ; spores purplish- 
brown, .0004 to .0005 in. long, .00025 to .0008 in. broad. 
- Plant 1.5 to 2.5 in. high, pileus 6 to 12 lines broad, stem 1 to 2 
lines thick. 
Among sphagnum. Karner. October. 
The species is related to Agaricus atrobrunneus, but its smaller size 
and differently colored lamellee will serve to distinguish it.
