Trametis Sepium Berk. 

 This species often occurs in a resupinate form, which, when 

 growing in the woods, is sometimes several inches in extent. The 

 pileate form is generally very narrow though sometimes greatly 

 elongated laterally by the confluence of several individuals. 



Stereum complicatum F^. 

 Var. laceratum. IMargin of the pileus lacerated or multifid. 



Shokan. September. 



Pterula setosa Pk. 



Dr. Patouillard has founded a new genus, Hirsutella, to which 

 he has transferred this species. He also transfers Thelephora 

 pedicellata Schw. to a new genus, ISejytohasiclium.. 



Comatricha aqualis Pk. 

 Mr. Geo. Massee, in his Monograph of the Myxogastres, con- 

 cludes that the genus Comatricha is so intimately connected with 

 the genus Stemonitis that it is untenable. He therefore places 

 this and other species of Comatricha in Stemonitis. This species 

 is sometimes abundant on decaying wood of sugar maple in the 

 Adirondack forests. The thin fugacious walls of the sporangia 

 have a silvery luster. 



Trichia reniformis Pk. 



Bark of striped maple, Acer Pennsylvanicum. Fulton Chain. 

 August. A rare but well-marked and very distinct species. The 

 clustered or subc£espitose mode of growth, the brown color of the 

 peridia and the short elaters are peculiar features. It has also 

 occurred at Karner on bark of red maple, Acer ruhrwn. 



Didymiuin microcarpum. Rost. 



An apparent variety of this species has spores a little larger 



than in the type and on smooth surfaces the stem rises from a 



circular h3'pothallus, which is adoi'ned with radiating lines as in 



D. radiatum. 



Chrysomyxa Pyrolae Rosir. 



Living leaves of Pyrola chlorantha. Delmar. June. The uredo 

 form on this host has the sori much move scattered than on the 

 leaves of Pyrola rotundifolia.
