the base, fiirfuraceous at the top, hollow, white; spores subglobose,. 

 nodulose, 8-10 x 6-8 ij., cystidia 40-60 x 12-20 //. 



Pileus 1.5-2.5 cm broad; stem 3-5 cm long, 2-4 mm thick. 



Mossy gromid in low woods. Essex co. September. 



The resemblance of this species to some forms of Inocybe 

 geophylla (Sow.) Fr. is so close that it is important to have 

 a knowledge of its spore characters in order to make a satisfactory 

 determination. The specific name is suggestive of this fact. Some- 

 times the margin is so abundantly and deeply split that the radiating 

 lobes give a stellate appearance to the pileus. Inocybe com- 

 mix t a Bres., Inocybe u m b r a t i c a Quel, and Inocybe 

 leucocephala Boud. are given as synonyms of this species by 

 Massee. 



This species has been reported as having caused a slight tempor- 

 ary illness in some members of a family who had specimens of it 

 prepared for the table and partook of them. It is well therefore to 

 consider it a poisonous or at least an unwholesome species. 



Viscidae 



Pileus viscid becoming smooth. 



This section connects the genus Inocybe with the genus Hebeloma, 

 the viscid pileus being common to it and Hebeloma. The character, 

 " becoming smooth," does not rigidly apply in all cases, for in some 

 of the species the pileus is more or less persistently silky or fibrillose 

 or hairy on the margin.
