BURT — THELEPHORACEiE OF NORTH AMERICA. I 215 



ate and somewhat imbricated, fibrous-tomentose, margin thick 

 and entire; substance concolorous with the upper surface, 

 spongy, more than 2 mm. thick, with hyphae 4^-5m in diam- 

 eter; hymenium inferior, even, not polished, cinnamon-buff; 

 basidia simple; spores deep olive-buff under the microscope, 

 echinulate, 8-10 x 6-8)U. 



Pileus 2-4 cm. in diameter when circular, or 1-2| cm. long, 

 2-4 cm. broad, often 1 cm. thick at base when dimidiate. 



Running up and encircling twigs on the ground and against 

 the base of shrubs. Canada to Louisiana and west to Wiscon- 

 sin. August. 



Peck describes the odor as quite fragrant at first but states 

 that it is lost after a few weeks; I did not notice any especial 

 odor for my collection. T. albido-hrunnea may be distinguished 

 from our other dimidiate and reflexed species of Thelephora by 

 its even and pale hymenium and thick spongy pileus. Schwei- 

 nitz confused one collection of this species with T. biennis Fr., 

 from the specimen of which in the Fries Herbarium, at Upsala, 

 it is clearly distinct. The types of Stereum spongiosum Massee, 

 viz., Curtis, 8582, and Ravenel, 1732, in Kew Herbarium, have 

 colored echinulate spores 8-10 x 6-7^, although described by 

 Massee as "eUipsoidese 6-7 x 4m" without mention of color and 

 projections of the wall. The type of Thelephora odorifera Peck, 

 in Coll. N. Y. State, is somewhat bleached or faded but quite 

 typical.
