 p. 533, Fig. '/IS. The peridiuni is snbgloljose or depressed pyriforui. The 

 outer coat, or cortex, consists of dense, soft warts or spines which fall 

 away after a time, exposing the smooth, shining, thin inner coat. The 

 spores are pale cinnamon-brown, slightly oval, 3-4 x 4-5 ,", smooth, with 

 slender hyaline pedicels 9-15 // loiii:. The capillitium consists of separ- 

 ate, branched threads, 3-(i /i in diameter, the branches gradually tapering 

 to sharj* points. Ellis and Morgan described this species in 1885 giving 

 it the siteclHc name of (Jliiciif<c but referring it to the genus Mycenastrum.

 and our locality is ai)parently in the extreme northern part of its distri- 

 bution. Judging from the general distribution and from the Illinois and 

 Ohio localities it would seem that this species is likely to be met with in 

 the southern half of Indiana.
