70 FORTY-FIRST ANNUAL REPORT ON THE 
Psilocybe clivensis, B. & Br. 
Borders of woods. Catskill mountains. September. 
Psilocybe senex, 2. sp. 
Pileus thin, hemispherical, obtuse, hygrophanous, dark brown and 
striatulate when moist, pale cinereous and shining when dry, some- 
what squamcse with superficial’ subfasciculate whitish fibrils, the 
margin appendiculate with the same; lamelle broad, subdistant, 
adnate, at first grayish, then brown or blackish-brown with a white 
edge; stem slender, hollow, fragile, minutely floccose-pruinose, sub- 
pellucid, white; spores brown, elliptical, .0003 in. long, .0002 broad. 
Pileus 6 to 10 lines broad; stem 1.5 to 3 in. long, 1 line thick. 
Decayed wood in woods. Catskill mountains. September. . 
The species is apparently related to P. canifaciens, but is at once 
distinguished by its slender white stem. The specific name has refer- 
ence to the white hairs or fibrils of the pileus, which are suggestive 
of the white hairs of old age. 
Deconica subviscida, n. sp. 
Pileus thin, at first subconical, then convex or néarly plane, often 
slightly umbonate, glabrous, hygrophanous, pale chestnut or reddish 
tan color, subviscid and striatulate on the margin when moist, pallid 
or dull buff when dry; lamellz broad, subdistant, adnate or slightly 
decurrent, at first whitish or dingy, then brownish ferruginous; stem 
equal or tapering downwards, fibrillose, hollow, brownish toward 
the base, paler above, the fibrils whitish or grayish; spores ovate, 
brown, .0003 in. long, .0002 broad. 
Pileus 3 to 6 lines broad; stem about 1 in. long, 1 line thick. 
Horse dung and manured ground. Menands. August. 
This species has many characters in common'‘with D. bullacea, from 
which I have separated it because of its scarcely viscid pileus without 
f 
a separate cuticle, and its different spores. It is gregarious, and in 
wet weather appears in great abundance and in successive crops. The 
slight whitish veil is perceptible in the young plant. 
Psathyrella minima, n. sp. 
Pileus membranous, hemispherical, ob+ se, obscurely striatulate 
when moist, even and pruinose-atomate when dry, dingy-yellow or 
reddish-brown, becoming paler in drying; lamelle broad, adnate, 
white, becoming yellowish-cinnamon ; stem capillary, minutely mealy — 
or furfuraceous under a lens, pellucid, white ;. spores black, narrowly 
elliptical, .00025 to .0003 in. long .00012 to .00015 broad. 
Pileus 1 to 2 lines broad ; stem 4 to 6 lines long. |
