S. Spongia is distinguished from our other species in the 
group having a glabrous hymenial erust by the spongy, 
rather than pillared, strueture of the middle region of the 
fruetifieation. The surface of the cotype is infested with 
a colorless hyphomyeete whose hyphae are densely crowded 
together and agglutinated; hence fertile specimens of this 
species will probably be browner than the original sterile, 
infested specimen.
