 216 AXNALS OF THE MISSOURI BOTANICAL GARDEN 



nodose-septate, 4—6/i. in diameter, sometimes collapsed; ba- 

 sidia with 4 sterisrmata; spores darker than the hyphae, 

 snbglobose, sometimes flattened on one side, the spore body 

 6-7(1 in diameter and short-aculeate in European and occa- 

 sional American specimens, but more commonly 6-8 X 6/u. 

 and echinulate in American specimens. 



Fructifications 2-10 cm. long, 1-2 cm. broad. 



On rotten coniferous and frondose wood of several species. 

 Canada and New Brunswick to New Jersey and in Montana. 

 July to October. 



In the color of H. fuscus, there is a perceptible vinaceous 

 component by which the species may be approximately rec- 

 ognized at sight. Confirmatory characters are the separable 

 fructification and microscopical details of sections. The 

 spores of most American specimens have slenderer and 

 longer spines than those of European collections. H. fuscus 

 is presented here as understood by Bresadola.
