gatherings of the latter species, the length of the stalk is subject to 

 great variation. B. dictyospora 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. rubiginosa, the spores are minutely 

 spinulose. Thefl^ are intermediate degrees of roughness in American 

 specimens which unite the two forms.
