REPORT OF THE STATE BOTANIST I906 2.y 



Mycena albogrisea n. sp. 



Pileus thin, submembranaceotis, ovate or subcampaniilate, obtuse, 

 glabrous, sulcata striate, grayish white ; lamellae rather thick, broad, 

 distant, adnate, colored like the pileus; stem slender, glabrous, 

 hollow, paler than the pileus, with a whitish strigose villosity at the 

 base ; spores .0003 of an inch long, .00016-.0002 broad. 



Pileus 3-5 lines broad, nearly as long; stem 1-2 inches long, 

 about half a line thick. 



Attached to fallen leaves of coniferous trees. Bolton, Warren co. 

 September. It belongs to the section Basipedes. lii the dried 

 specimens the pileus has assumed a slightly darker or smoky tint, 

 but it still retains its sulcate striate character. 



Nicandra physaloides Gaertn. 

 Gloversville, Fulton co. September. W. C. Cottrell. Introduced 

 from Peru. The common name of its fruit is apple of Peru. In 

 Illustrated Flora of the Northern States and Canada its name is 

 given as Physalodes physalodes (L.) Britton, but the 

 International Botanical Congress having decided against the use of 

 double names, we have used the name given in Gray's Manual. 



Omphalia pusillissima n. sp. 



Pileus membranaceous, broadly convex or nearly plane, glabrous, 

 umbilicate, slightly striate on the margin when dry, white ; lamellae 

 few, distant, decurrent, white ; stem slender, filiform, flexuous, 

 glabrous, white ; spores subglobose or broadly elliptic, .0002-.00024 

 of an inch long, .00016-.0002 broad. 



Pileus 1-2 lines broad ; stem 3-5 lines long. On humus and decay- 

 ing twigs under pine trees. Delmar, Albany co. August. 



This is one of the smallest species of Omphalia known to me. 

 The lamellae are very narrow, sometimes branched and sometimes 

 absent. It is a smaller mushroom than Omphalia inte- 

 grella, and differs from it in its umbilicate pileus. The stem is 

 hollow but the cavity is minute. 



Ohleria modesta Fckl. 



On carious wood of beech. Lyndonville, Orleans co. March, 

 C. E. Fairman. 



Panicum deminutivum n. sp. 



Culms 4-10 inches tall, slender, erect, branched, slightly hairy 

 near the base ; branches 3-6, short, suberect, each terminating in a
