BURT — THE NORTH AMERICAN SPECIES OF CLAVARIA 51 



parco albo orbiculari oriundo. No. 974 is one forked and narrow. 



"On wet-rotting stumps/' 



A rectangular piece of white paper was slipped back of three 

 fructifications to render them more visible in the photograph. 

 The clubs are now clavate, orange-cinnamon (resin-colored), 3 

 mm. long; such spores as were found are hyaline, even, sub- 

 globose, 4X<M / L > H — so few in number that I am not sure/ they 

 belong to this fungus.
