Siibgenus 27. Psatiiteella.—Veil not interwoven. Pileus membranaceous
; margin not reaching beyond the gills.
351. A. (Psathyrella) gracilis, Fr.; pileus suhmembraiia-
ccous, conical, slightly striate ivhen moist, hygrophanous;
stem slender, straight, naked, pallid; gills broadly adnate,
rather distant, cinereous-black, edged with pale-rose.
On hedge-borders. Very common. Pileus brownish, at
length often tinged with pink.
352. A. (Psathyrella) hiascens, F r .; pileus membranaceous,
campanulate, deeply sulcate; disc even; stem straight, rigid,
brittle, smooth, white; gills adnate, linear, rather distant,
acute in front, pallid, then black.—Bull. t. 552. / . 2 F.
Under hedges. Woodnewton. Pileus 1 inch high, 14
inch across, sulcate up to the disc, pale dirty-ochraceous.
353. A. (Psathyrella) aratus^ n. s . ; pileus membranaceous,
campanulato-conic, rather acute, deeply sulcate; stem tall,
thickened at the base, wliite, smooth, fistulöse; gills lanceolate,
quite free, purplish-black.
Under hedges. Woodnewton. Pileus 1 inch high, f across,
bright brown; flesh of the disc of the same colour; stem 5
inches high. Allied to A. hydrophorus, Bull., but clearly
distinct.
354. A. (Psathyrella) atomatus, Fr. ; pileus submembranaceous,
campanulate, obtuse, slightly striate, hygrophanous,
wlieu dry rugulose, sparkling; stem brittle, white, mealy above;
gills broad, adnate, cinereous-black.
About hedge-hordcrs, etc. Very common. Pileus at first
brownish, then tinged with pink.
355. A. (Psathyrella) disseminatus, P .; pileus membra%
AGARICINI. 177
naceous, ovato-campanulate, furfuraceous, then naked, sulcato-
phcate, changing colour; stem somewhat flexuous, brittle
furfuraceous, then smooth; gills adnate, broadly linear, dirty-
white, then black.—Sow. t. 166.
About the trunks of trees, and on the ground. Porming
large tufts. Extremely common. Pileus a few lines only
across. Approaching very near to Coprinus. A. membra-
naceus, Bolt., is too doubtful as to its afflnities to admit of
its being registered.
2. COPEINUS, Fr.
Gills membranaceous, deliquescent. Spores black.
1. Pileus not plicato-sulcate.
1. C. comatus, F r .; pileus rather fleshy, cylindrical, obtuse,
then expanded, soon torn up into hroad, scattered scales;
stem hollow, fibrillose, stuffed with a cottony weh; bulb solid,
rooting; ring moveable; gills free, linear, white, then tinged
■with red.—Crev. t. 119.
Sides of roads, pastures, etc. Common. Extremely variable
in size. Esculent when young. I believe that Bolt. t. 142
IS a mere variety. I have found C. comatus at Abergele equally
dwarf, and with a precisely similar volvatc ring.
2. C. sterquilinns, F r.; pileus memhranaceous, conical,
expanded, sulcate, at first villous; disc rather fleshy, rough
with scales; stem attenuated, fibrillose, solid, rootless, having
a ring; gills free, ventricose, purplish.—Mich. t. 83. / . 3 .
On dung. Rare. King’s Cliflh. About 14 inch across.
3. C .atramentarius,Fr.; pileus rather fleshy, ovate, at
first irregular, spotted ahove with innate scales; stem firm,
hollow, zoned within; ring abrupt, fugacious; gills free, ven-
tricóse^ whitCj then purplish-black. (Plate 12, fig. 1 .)
