Aaaricus (INOCYBE) EUTHELOIDES 7”. sp. 
Pileus thin, conic or campanulate, then expanded, distinctly umbonate, 
silky-fibrillose, subrimose, varying in color from grayish-cervine to chestnut- 
brown, the disk sometimes squamulose ; lamelle moderately close, rather 
broad, ventricose, narrowed or rounded behind, adnexed, whitish, then ferru- 
ginous-brown, white and denticulate on the edge; stem equal, subflexuous, 
solid, whitish-fibrillose, pallid ; spores even, uninucleate, gibbous or unequally 
elliptical, .00035'—.0004’ long ; flesh of the pileus white. 
Plant 1 —2' high, pileus 6 /-12! broad, stem 1'/-2’' thick. 
Ground in woods. Brewerton. Sept. 
The species seems to be closely aed to A. eutheles, from which it differs 
in the character of the lamellw, which are rather abruptly and strongly 
narrowed behind, in the absence of a farinaceous odor and in the character of 
the spores. The stem is paler then the pileus, sometimes being nearly white. 
The species belongs to the section Rimosi. 
Agaricus (INocYBE) INFELIX 7. sp. 
Pileus campanulate, convex or expanded, subumbonate, fibrallese: -squamu- - 
lose, grayish-brown or umber ; lamella close, emarginate, ventricose, rather 
broad, whitish, then ferruginous-brown ; stem equal, solid, pallid or whitish, 
sometimes darker toward the base, silky fibrillose, white and pruinose at the 
top; spores oblong, .0004'-.0005’ long, about .0002’ broad; flesh of the 
pileus white, odor none. 
Plant 1-2’ high, pileus 6 ‘-12° broad, stem 1’'—2” thick. 
Sterile mossy ground in open places. Indian Lake. Aug. 
The species belongs to the section Laceri. In wet weather the pileus 
becomes more lacerated than in dry. It generally becomes paler with age. 
A small form occurs in which the pileus is scarcely umbonate and 4-6! 
broad, with the stem about half an inch high. The oblong spores afford a 
ready character by which to separate this species from the preceding.
