 182 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



Fructifications 2 cm. in diameter up to 10X3 cm.; reflexed 

 portion 2-8 mm. broad. 



Under side of hemlock, spruce, and pine boards and logs and 

 charred wood. Canada to Pennsylvania and westward to 

 Montana; received also from Russia where growing on rotten 

 wood in greenhouse. 



S. radiatum is readily recognized by its bright, ferruginous 

 hymenium with shallow broad ridges radiating from the center 

 to the margin, and by the black upper side of the pileus when 

 reflexed. The general aspect, coloration, and color changes 

 with KHO solution are suggestive of some species of Hymen- 

 ochaete but no setae are present. I endeavored to have com- 

 parison made with the type of Thelephora corrugata in Museum 

 of Paris Herbarium but. Patouillard could not find the specimen 

 there.
