96. Agaric us perplexus n. sp. 



Pileiis fleshy, convex, then expanded, often broadly subum- 

 bonate, smooth, yellow, the disk red or brownish-red, the 

 margin paler ; lamelL'B not broad, rounded at the inner 

 extremity, easily separating from the stipe, pale yellow, then 

 greenish-tinged, finally purple-brown ; stipe subequal, firm, 

 slightly fibrillose, hollow, yellow, reddish at the base ; flesh 

 white ; spores purplish-brown. 



Height 2-3', breadth of pileus 2-3', stipe 2"-3" thick. 



About stumps in woods or open places. Common. Sand- 

 lake, Albany and Catskill Mountains. September and October. 



The plant has a mild taste and no marked odor. It grows 

 singly or in dense tufts. It is closely related to A. suMateri- 

 tlus, A. einxanthus and A. fascicular is., but as it does not 

 agree with the description of either of them, I have no alterna- 

 tive but to describe it as a new species. 



97. Agaricus velutijS^us Pers. 



Pileus fleshy, thin, convex or expanded, brittle, minutely 

 tomentose-scaly, becoming smooth, hygroi^hanous, yellow 

 with the disk reddish ; lamellae rather broad, attached, tapering 

 toward the outer exti^emity, dark brown tinged with red, the 

 edge whitish-beaded ; stipe equal, rather slender, hollow, 

 fibrillose, subconcolorous, white-mealy and slightly striate at 

 the top ; spores black.

Roadsides. Albany Cemetery. September. The pileus 

 sometimes cracks transversely. 



Subgenus — Psiloeybe. 

 Veil, if present, not forming a ring. Margin of pileus at first 



incurved. — Berlc. Outl. 

 The species of this subgenus are smaller, and have the pileus 

 thinner than those preceding.
