Clavarias of the United States and Canada 63 



Clavaria asperulospora Atk. Ann. Myc. 6: 55. 1908. 



Plate 81 



This seems to be a good species with spores unlike any other 

 Clavaria of similar form. The dried plants are quite simple, 

 much shrunken, apparently not hollow, nearly black, the very base 

 paler. A part of the type from Bresadola's herbarium shows the 

 spores to be spherical, asperulate, with a distinct, pointed mucro, 

 4.8-6.2[x thick (omitting mucro). 



Atkinson's description follows : 



"Plants clustered, wood-brown, 4-7 cm. high, 2-3 mm. stout, 

 cylindrical, blunt, tapering below. Basidia abruptly clavate, 

 30 x 10-12[/., 4-spored. Spores globose, white, echinulate, pedicel- 

 late, 6-7y."

This species has been badly confused, but is now easily recog- 

 nized through the work of Cotton, who has cleared up the difficul- 

 ties (Trans. Brit. Myc. Soc. 2: 163. 1908). It has been often 

 reported in America, but most if not all such reports (except 

 Burt's recent one from Massachusetts and Vermont) were based 

 on some other interpretations of the species than the one here
