22 Annual Report of the State Botanist. 



It seems to be closely related to H. Micheneri, but separated from 

 it by the conical aciilei. In this species also they are sometimes 

 crowned with one to four cilia. The specific name has reference to 

 the character of the subiculum. 



Odontia tenuis n. sp. 



Eifused, very thin, tender, dry, pallid, the margin not clearly 

 fimbriate ; verrucse minute, scarcely visible to the naked eye, sub- 

 g-lobose or oblong, scattered or crowded, sometimes entire ; mycelium 

 sometimes collected into dingy -yellowish branching slender threads. 



Much decayed wood of birch, Betula lutea. Salamanca. Sep- 

 tember. 



In texture and structure this resembles Odontia fusca, in color, 



0. fimhriata. 



Mucronella minutissima n. sp. 



Aculei very minute, about one-sixth of a line long, gregarious, 

 subulate, white; spores minute, elliptical, .00016 in. long, .0001 

 broad. 



Decaying oak wood. Clarksville, Albany county. September. 



This species is so minute that it is scarcely visible to the naked 



eye. The measurement of the aculei here given was taken from the 



dried specimen. In the fresh plant it would probably be a little 



greater. 



Thelephora odorifera n. sp. 



Pilei 8 to 12 lines broad, csespitose, subcoriaceous, subdimidiate, 

 imbricated, fibrous-tomentose, dingy- whitish or grayish ; hymenium 

 even, not polished, concolorous ; stems short or none ; spores globose, 

 echinulate, colored, .0003 to .00035 in. broad. 



Rich soil under cedar trees. Jamesville. July. Underiuood, 

 The species is apparently related to T. intyhacea, but it differs 

 from that fungus in its paler color, smooth hymenium and larger 

 spores. The specimens at first were quite fragrant, but the odor 

 was lost after a few weeks. 



Porothelium fimbriatum Fr. 

 Decaying wood. Carrollton. September. 



Cyphella arachnoidea n. sp. 



Irregularly cupular, unequal, very thin, membranous, tender, 

 minutely downy externally, pure white, the hymenium in large 

 specimens somewhat uneven; spores subglobose, .00016 to .0002 in. 

 long, .00016 broad.
