BURT — THE NORTH AMERICAN SPECIES OF CLAVARIA 29 



36. C. myceliosa Peck, Torr. Bot. Club Bui. 31: 182. 1904; 

 Sacc. Syll. Fung. 17: 196. 1905. Plate 6, fig. 37. 



Type: in N. Y. State Mus. Herb. 



"Stem slender, solid, irregularly branched above, tawny, with 

 an abundant mycelium which forms whitish, branching strands 

 among decaying leaves and twigs; branches short, divergent or 

 wide spreading with few branchlets, colored like the stem, the 

 ultimate branchlets mostly acute, whitish; spores subglobose, 

 4 (j long. Scattered or gregarious, 1-2.5 cm. tall, stems about 

 .5 mm. thick. 



"Among fallen leaves and twigs under redwood trees. Moun- 

 tains near Stanford University, California. December. E. B. 



Copeland. 



"The abundant rhizomorphoid mycelium is a marked feature 

 of this species. The plant is inodorous but has a slight peppery 

 taste. It is allied to our eastern C. pusilla, but it is a smaller, 

 more slender plant with the slender stem branched above only, 

 and with the few short branches more widely spreading." 



The fructifications are now Saccardo's umber, with conspicuous 

 and numerous, whitish mycelial strands at the base ramifying 

 among the humus of decaying redwood leaves; spores colored, 

 rough, 4-4 1 / 2 X2 :1 /.-3 m, glued together in small masses. 



This species is noteworthy by its slender form, branching 

 above, prong-like branches, and peppery taste.
