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, Fr. 

 Bare soil and on decaying wood. South Ballston. Aug. 



Agaricus jubatus, Fr. 



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, n. sp. 



Pileus thin, flexible, convex or nearly plane, centrally depressed, 

 glabrous, subshining, sometimes concentrically rivulose, grayish-brown ; 

 lamellae 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, .0003 in. long, .0002 broad ; flesh whitish 

 or grayish-white, odor almost none, taste mild. 



Plant I to 2 inches high, pileus 6 to 12 lines broad, stem about i 

 line thick. 



Thin pine woods. Karner. Oct. 



The species is apparently related to A. cicatrisaiiis. 



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 lamellae. 



Agaricus villosus, Fr. 



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, Fr., van 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. destruens, 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 in. long, .0002 to .00025 broad.
