86 THIRTY-EIGHTH REPORT ON THE STATE MUSEUM. 
The specimens agree very well with the description of the species, 
but they appear to have occurred out of season. 
Agaricus scyphoides, /r. 
Bare soil and on decaying wood. South Ballston. Aug. 
Agaricus jubatus, /r. 
Damp ground in thin woods. West Albany. Sept. 
The specimens were few in number and not fully developed. The 
pileus was conical, and clothed with a short, close, velvety pubescence, 
and the stem was solid. In these respects the specimens do not agree 
well with the description of the species, although bearing a striking re- 
semblance to the figure of the species in Mycological Illustrations. We 
have, therefore, for the present, referred them to this species. 
Agaricus (Clitopilus) unitinctus, 7. sp. 
Pileus thin, flexible, convex or nearly plane, centrally depressed, 
glabrous, subshining, sometimes concentrically rivulose, grayish-brown ; 
lamelle narrow, moderately close, adnate or slightly decurrent, colored 
like the pileus ; stem slender, straight or flexuous, subtenacious, equal, 
stuffed, slightly pruinose, grayish-brown, with a close, white mycelioid 
tomentum at the base, and white, root-like fibres of mycelium penetrat- 
ing the soil ; spores elliptical, .o003 in. long, -ooo2 broad ; flesh whitish 
or grayish-white, odor almost none, taste mild. 
Plant 1 to 2 inches high, pileus 6 to 12 lines broad, stem about 1 
line thick. 
Thin pine woods. Karner. Oct. 
The species is apparently related to A. echiraugtiee 
Agaricus atrides, Lasch. 
Damp ground in woods. Caroga. July. 
This species differs from A. serrulatus by its decurrent lamellae, and 
from A. Watsoni by its darker color and blackish. denticulations on the 
edge of the lamelle. 
Agaricus villosus, /r. 
Prostrate trunks of poplars. West Albany. Aug. 
Our specimens are pale-yellow or buff, becoming darker with age. In 
other respects they correspond to the characters of the species. 
Agaricus comosus, /’., var. albus, Pk. 
Trunks of horsechestnut. Albany. Oct. 
Two specimens only were found. These were white, becoming tinged 
with yellow in drying. ‘The typical form of the species is tawny. From 
A. destrwens, with which our specimens agree more closely in color, 
the viscidity of the pileus will separate them. The spores are ferrugi- 
nous, ,0003 to .00035 ih. long, .oo02 to .o0025 broad,
