gatherings of the latter species, the length of the stalk is subject to 
great variation. B. cJ/cti/OKjm-a is the name given by Rostafinski 
to the Appin specimen (K. 193), in which the spores are strongly 
reticulated. British gatherings have more or less of this character, 
with prominent warts isolated or confluent ; in most American 
specimens and in that from Chevallier at Paris, which is given by 
Rostafinski as the type of B. ruhiginosa, the spores are minutely 
spinulose. There are intermediate degrees of roughness in American 
specimens which unite the two forms.
