Habit, Habitat, and Distbibutiox — Gregarious under balsam and 

 spruce, Wilderness State Park, Mich., October. 



Matebial Studied — Michigan: Smith 43858 (type, Oct. 7, 1953). 



Obsebvatioxs — Wilderness State Park, Michigan, is the one place 

 in the United States where Smith has found H. pudorinus fruiting 

 abundantly every autumn when rainfall has been adequate. During the 

 season of 1953 which was relatively dry, there were numerous groups 

 of carpophores, but the individuals averaged smaller than those col- 

 lected during the wet year of 1951. During 1953 var. subcinereus was 

 encountered on several occasions and regarded merelv as faded normal
