102 Forty- SIXTH Report on the State Museum. 



Scirpus Peckii Brltton. 

 Lake Pleasant, Hamilton County. August. First collected 

 in this locality in 1875. It was again collected in 1891, 

 but in a new station. It was reported last year under 

 the name Scirpus polyphyllus var. macrostachys. Professor 

 Britton has recently published it as a distinct species, and as such 

 it is now reported. It certainly is quite distinct from our ordinary 

 forms of S. polypliyllus. Specimens sometimes occur in which a 

 cluster of spikelets is borne on a long pedicel issuing from the 

 axil of the uppermost leaf.

Tricholoma serratifoliuni n. sp. 



Pileus fleshy, firm, convex or nearly plane, often irregular, dry

 serrate or eroded on the edge, white; stem short, stout, solid, 

 white; spores broadly elliptical or subglobose, .0002 to .00024 in. 

 lontr, .0002 broad. 



Pileus 2 to 4 in. broad ; stem about 1 in. long, 3 to 6 lines 

 thick. 



Woods. Shokan. September. 



This is apparently related to such species as T. psam^mopoihom 

 and T. impoUtum^ but distinct from them in color and in the 

 character of the lamellse. 



Tl^icholoina submaculatuni n. sp. 

 Pileus convex or nearly plane, sometimes slightly depressed in 

 the center; glabrous, brownish, sometimes tinged with ferrugin-
