Fructification coriaceous-spongy, dry, effuso-reflexed, with 

 the upper surface tomentose, snuff-brown, the margin entire; 

 hymenium mouse-gray and some- 

 what pruinose in the older portion, 

 snuff-brown and veined toward the

 termediate layer 150 n thick, com- 

 posed of longitudinally interwoven, 

 colored hyphae 3-4 n in diameter, 

 with the hymenial layer up to 200 

 fj, thick, zoned, containing cystidia 

 in all its portions; cystidia colored, 

 heavily hyaline incrusted on the 

 outer half, slender-pointed, 45-60 

 X5-12 \x, protruding up to 30 jjl; 

 spores hyaline, even, 5-6 X 3-3 J jjl.

Fructifications of this species have the general aspect of those 

 of S. papyrinum, but are thinner, more compactly inter- 

 woven, with slenderer cystidia, and have the hymenial layer up 

 to 200 ju thick and composed of several zones; cystidia are 

 present in each of these zones, and those of the innermost zones 

 do not reach to the surface of the hymenium. In S. papyrinum
