BURT THELEPHORACEAE OF NORTH AMERICA. IX 



181 



im/ 



On balsam fir, spruce, and Thuja plicata. Newfoundland to 

 New York and westward to Oregon. Infrequent. 



The aspect of A. amorphus is that of a small Peziza, which 

 may account for the infrequency of this species in the col- 

 lections which have been sent to me for determination. The 

 large, minutely spinulose spores and moniliform paraphyses 

 are distinguishing 

 microscopic c h a r - 

 acters. The echinu- 

 late marking of the 

 spores is very faint 

 in the collections 

 from Idaho west- 

 ward.
