78 TWENTY-FIFTH REPORT ON THE STATE MUSEUM. 
Acaricus (PHottora) piscotor Peck. 
Pileus thin, convex, then expanded or slightly depressed, 
smooth, viscid, hygrophanous, watery-cinnamon and striatulate on 
the margin when moist; bright ochraceous-yellow when dry ; 
lamellz close, narrow, pallid then pale ferruginous; stem equal, 
hollow, fibrillose-striate, pallid ; annulus distinct, persistent ; spores 
elliptical, .00028' long, .0002’ broad. 
Plant subcespitose 2'—3' high, pileus 8’-16" broad, stem 1° thick. 
Old logs in woods. Greig. September. 
The change of color from the moist to the dry state is very 
marked. This species resembles Agaricus autumnalis, in which 
the annulus is fugacious and the spores are longer. The edge of 
the lamellee in both is white-flocculose. 
Acaricus (HpELoMaA) PALLIDOMARGINATUS Pech. 
Pileus brittle, broadly convex, sometimes irregular, smooth, 
hygrophanous, brown with a pale margin when moist, ochraceous 
and subatomaceous when dry; lamell close, thin, rounded and ~ 
slightly emarginate at the stem, tapering outwardly, ochraceous 
brown ; stem usually long and flexuous, equal or tapering upward, 
hollow, a little paler than the pileus, white-floccose at the base ; 
spores subelliptical, .0004' long, .0002' broad. © 
Plant gregarious, 1'-3' high, pileus 6"-12" broad, stem 1° thick. 
Ground in swamps and wet places. Sandlake. September. 
AGARICUS PUTRIGENA B. & C. 
Dead branches. North Elba. July. 
AGARICUS SquAMosus /7. 
Among fallen leaves in open woods. Portville. September. 
Our specimens have the pileus red, the lamellee olivaceous and 
spotted, the annulus not distant and the spores .00045' long, and 
must therefore be regarded as varying somewhat from the typical 
form of the species.

ous, pale alutaceous; lamellz close, narrow, rounded at the stem, 
pallid, then rosy-brown ; stem equal, stuffed, pruinose at the top, 
substriate, white; spores elliptical, nucleate, .0005’ long. 
Plant cxspitose, 2’ high, pileus 1'-2’ broad, stem 2” thick. 
Mossy base of the sugar maple. North Elba. September.
