Pennsylvanica. The characters by which it is separated from E. Penn- 

 sylvamca are, according to the author of the species, " its slender culms 

 and panicle, the very short cauline leaves, the longer and wider lower 

 glume, the more obtuse upper one and the shorter obtuser flowering 

 glumes." The flowers have a peculiarly blunt appearance by which the 

 plant may be easily recognized. 



Bromus arvensis, L. 



Troy. Gordinier and Hoive. Sparingly introduced. June. 



Lepiota granosa, Morg. 



Prostrate trunks of trees, old stumps and decayed wood. Catskill 

 mountains. September. 



Our specimens do not agree rigidly with the description of the spe- 

 cies to which we have refei ed them. The pileus is either obtuse or 

 umbonate, even or radiately rugose- wrinkled, and is generally even 

 and regular on the margin. The stem also is either equal or slightly 

 thickened at the base, but these variations are not of specific impor- 

 tance. The flesh of the stem is yellowish as in Lepiota amianthinus to 

 which this species is' closely related, both in color and structure, but 

 from which it may be distinguished by its habitat, its larger size and 

 its entire membranous persistent annulus. 



Lepiota arenicola, n. sp. 



Pileus at first broadly conical, then convex or nearly plane, obscurely 

 punctate with minute granular squamules, whitish or cinereous, sub- 

 striate and crenulate on the margin; lamellae broad, subventricose, 

 distant, free, white; stem slender, equal, stuffed, glabrous, whitish, 

 the annulus imperfect, obsolete or quickly evanescent; spores oblong 

 or subfusiform, acute at one end, .0005 to .0006 in. long, .0002 to 

 .00024 broad. 



Pileus 8 to 6 lines broad; stem 8 to 12 lines long, about 5 lines thick. 



Sandy soil. Karner, Albany county. August. 



The spores indicate an affinity of this species with L. metulispora, 

 of which it might be regared as a dwarf variety, but it differs in its 

 smaller size, more expanded pileus, distant lamellae and glabrous 

 stein. The mycelium binds the sand into a globose mass at the base 



of the stem. 



Tricholoma resplendens, Fr. 



Thin woods. Catskill mountains. September. 



Tricholoma Columbetta, Fr. 



Woods. Selkirk, Albany county. August.
