repent, non-gelatinous hyphae, 2-3 ;> broad — a cutis. Hypodermium 

 not differentiated. Pileus trama of radially disposed hyphae. (.lamp 

 connections on the hyphae of the cuticle and gill trama. 



Habit, Habitat, and Distribution — Gregarious on soil, at times 

 among moss, in deciduous, coniferous, and mixed woods. Colorado, 

 Michigan, Tennessee, and North Carolina, July-November; also Eu- 

 rope and Japan. 



Material Studied — Colorado: Whetstine, Grand Co., Aug. 9,

Observations — This species is related to //. borealis which has a 

 more slender stipe and smaller spores; to //. niveus in which the pileus 

 is viscid and the flesh thin; and to //. pratensis which has a colored 

 pileus (buff, orange, or rufous). 



In one North Carolina collection. Hesler 21005, the spore deposit, 

 although white at first. Became "maize yellow" on standing in the 

 herbarium. In another collection (from Tennessee, llesler L9548), the 

 stipe was pale pinkish lavender downward. This condition suggests 

 H. virgineus car. roseipes Massee. However, Orton ( I960, p. 217. foot- 

 note) observes thai //. virgineus, II. niveus, and //. berkeleyi are all 

 prone to a pathological condition ( see discussion of //. niveus
