[Vor. 8, 1921] 
396 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Fructification 4 em. in diameter. 
On spruce bark. Adirondack Mts., N. Y. June 7, 1905. 
Probably rare. 
The general appearance of H. Peckii is that of a Corticium, 
Coniophora, or Hypochnus, with the coffee-colored hymenium 
covering the reddish brown subieulum. The basidia are not 
crowded together as closely as in most species of Corticium and 
show well their hook-shaped form when thin sections are examined. 
Helicobasidium is a small genus and has not been recorded 
heretofore for America. I am indebted for the privilege of 
studying the present specimen to Dr. H. D. House who found 
it among the undetermined collections of Peck, to whose memory 
I dedieate the species in grateful regard for assistance and 
friendship which began in 1879.
