Annual Report of the State Botanist. 57 



The American plant differs slio^htly from the description of the 

 European, in having the lamellae somewhat decurrent, and on this 

 account it was fonnerly referred to the genus Clitocybe and 

 described as distinct. The spore characters here given are taken 

 from the American plant. 



Tricholoma album Schceff. 

 White Tricholoma 



(Hym. Europ.. p. 70. Syl. Fung.. Vol. v, p. 127.) 



Pileus fleshy, tough, convex, becoming plane or depressed, obtuse, 

 very dry, even, glabrous, white, sometimes yellowish on the disk, 

 rarely wholly yellowish, the margin at first involute, flesh white, 

 taste acrid or hitter; lamellse emarginate, somewhat crowded, dis- 

 tinct, white ; stem solid, elastic, equal or tapering upAvard, externally 

 fibrous, obsoletely pruinose at the apex, white; spores elliptical, 

 .0002 to .00025 in. long. 



Pileus 2 to 4 in. broad ; stem 2 to 4 in. long, 4 to 6 lines thick. 



Woods. Common. Albany, Essex, Herkimer, Cattaraugus and 

 Greene counties. August to October. 



This species is variable in color and in size, being sometimes 

 robust, sometimes slender. It grows singly, in troops or in tufts. 

 It has no decided odor but a bitter unpleasant taste. It departs 

 from the character of the tribe in having the pileus quite dry and 

 on this account, as Fries remarks, it might perhaps be better placed 

 in the tribe Sericella. The same remark is applicable to the two 

 following species. The variety ccesariatus differs from the typical 

 form in haA-ing the pileus thin, and at first silky, the lamellfe almost 

 free and the slender fragile stem somewhat pruinose at the apex. 

 T. alboides, Report 32, p. 25, apparently belongs to this variety. 



Tricholoma nobile Fk. 



Noble Tricholoma 



(N. Y. State Mua. Rep. 42, p. 17.) 



Pileus fleshy, convex or nearlj'^ plane, dry, minufebj punctate or 

 squamulose ivith innate fibrils, whitish or tinged with yellow, flesh 

 white, taste impleasant; lamelbe broad, rather close, rounded behind 

 and slightly adnexed, white, slowly changing to pale-yellow where 

 wounded ; stem equal, solid, slightly rioecose-pruinoso, whitish : 

 spores minute, subglobose, .00016 to .0002 in. broiul. 



Pileus 2 to 4 in. broad; stem 1.5 to 2.5 in. long, 4 to 8 lines tliick.
