This species has a smaller and more yellowish pileus than /. 

 sindoniaj fche spores and cystidia are similar. A variety has been 

 described by Peck with a distinct, webby cortina and more iibrillose 

 stem, as var. brutii.

Gregarious or scattered. On the ground in frondose and conifer 

 woods. Throughout the State. July-October. Common. 



One of our commonest [nocybes, although not often found in 

 abundance at one place. The clear, white, glossy cap ami stem are 

 characteristic, other white species which have been described are: 

 I. comatella Pk., a smaller plant, which has a hairy pileus ami at 

 times a reddish-brown stem, but the spores ami rystidia are the 

 same, usually grows on rotten wood; f. fallax Pk., with angular 

 or nodulose spores; /. infida l'k.. also with nodulose spines and a 



subscaly, reddish-brown umbo. Both the latter species have
