September. 



Known by its peculiar long tuberculate-striae on the margin of 

 the pileus and its thin evanescent volva. The annulus separates 



and breaks early, ami often clings to the apex of the bulb, simulat- 

 ing the species with close-fitting inrolled voha. It was found in 



great abundance all over the oak-barrens about New Richmond 

 during September, L910, ami is partial to sandy soil which clings 

 to its caps.
