Collybia lacerata Lasch. 

 Dry soil among grasses and bayberry bushes. Fishers island, 

 Suffolk CO. October. C. C. Hanmer. In these specimens the ex- 

 panded pileus is umbonate and the iniibo is darker colored than the 

 rest. The specimens agree well with the figure of the species as 

 given in Cooke's Ilhistrations of British Fungi. The spores in 

 our specimens are broadly elliptic or subglobose and .00024-0003 

 of an inch long.

 Coopers Plains, Steuben co. September. 



A cluster of six plants was found growing in a small excavation 

 near a farmhouse. The weather had been unusually warm and 

 dry for several weeks, but a soaking rain two days before and a 

 thunder shower one day later seem to have been favorable to the 

 development of this large fine musliroom. It belongs to the section 

 Dermoeybe.
