845 



Pileus 1 to 2 inches broad; stem i to 2 inches long, 2 to 3 lines 

 tnick. Gregarious or subcespitose. Stony pastures. Near War- 

 rensburg. October. 



The species belongs to the tribe Indusiati. In some of the 

 specimens there is a narrow, brown circumscribing zone or line on 

 the pileus near the margin. 



Naucoria pennsylvanica B. & C. 



Decaying wood. Near Warrensburg. Octrber. 



Psilocybe dichroa (Pcrs.) Karst. 

 Swamps and wet places. Karner. October. 



Psilocybe unicolor n. sp. 



Pileus thin, broadly convex, hygrophanous, striatulate and brown 

 when moist, even and pale brown or whitish when dry, flesh white, 

 taste slightly disagreeable; lamellae narrow, thin, close, adnexed, 

 brownish becoming darker with age; stem short, straight or curved, 

 equal, glabrous, stuffed or hollow, brownish, a little paler than the 

 pileus; spores brown, elliptic, .00024 of an inch long, .00016 broad. 



Pileus 6 to 10 lines broad; stem 8 to 12 lines long, about 1 line thick. 

 Decaying, prostrate, mossy trunk of some deciduous tree in woods. 

 Savannah, Wayne co. 



This species differs from P. camptopus, to which it is closely 

 allied, in its lamellae, which are adnexed and darker colored, and in 

 its stem, which is glabrous, stuffed or hollow and destitute of the 

 conspicuous, white, radiating hairs at the base. In that species 

 the lamellae are at first whitish, becoming reddish brown with age, 

 and the stem is solid, white and sprinkled with white, mealy particles. 



Boletus mutabilis Morg. 



Bare ground in thin woods along streams. Denning. August. 

 Our specimens differ in some respects from the typical form, but in 

 essential characters they agree too well to warrant their separation. 

 The mouths of the tubes are rather small and nearly round, the stem 

 is even, equal or slightly tapering upward, slightly furfuraceous, yel- 

 low at the top and sometimes reddish at the base. The spores are 

 greenish brown or olivaceous, .0005 to .0006 of an inch long, .00024 

 to .0003 broad. The tubes and flesh quickly or instantly become 

 blue where cut or broken.
