Plates 20 and 83 



This species was described from Chapel Hill plants collected 

 by us, and the following is the original description by Atkinson : 



"Plants very much branched from base, 7 cm. high, 5-6 cm. 

 broad, trunk absent. Plants uniformly gray when fresh. Base 

 of branches whitish in drying, upper portion of plant becoming 

 pale ochre or buff. Branches dichotomous, slightly clavate, nu- 

 merous. Axils acute or rounded. Tips usually bidentate, teeth 

 rounded. Plants somewhat tough. Basidia slender, 4-spored, 

 40-45 x 7\x. [We make them 5.5-6.2[jl thick when measured in 

 water from the dried state; hymenium about 75\j. thick, packed 

 with small crystals.] Spores globose, smooth, white, pedicellate, 

 with large oil drop, 4-6(jl The plant resembles Clavaria cinerea in 

 color when fresh but the spores are much smaller, the branches 

 more slender. In size and shape the spores resemble those of 

 Clavaria fnsiformis but the plant is very different from that 

 species." 



This species has not been reported except from Chapel Hill, but 

 we have recently found it in the mountains and we hnd several 

 American collections and one European that appear the same. Of 

 the American lots one was in Peck's herbarium (Vaughns, Burn- 

 ham collection) mixed with C. Kunsei) two others were sent us 

 by Burnham for determination. The lot from Vaughns has just 

 the shape of the type, with long slender branches which divide 

 two or three times with open axils, the primary branches scurfy
