There is some variation in the size and color in different collec- 

 tions of this species. There is, however, less difference between the 

 type specimens O'f M . c a m p a n u 1 a t u s Pk., M . siccus 

 (Schw.) and M. clementsianus Sacc. and Sydow (M. 

 fulviceps Clements) than there is between different collections 

 of M.campanulatus made by Peck and deposited by him in 

 the New York State Museum. Like many other species of Mar- 

 asmius, the spores vary in length. It is claimed that mature spores
