Fructifications disk-shaped, scattered or sometimes con- 

 fluent, somewhat fleshy, drying coriaceous, attached by a 

 point, the margin free, elevated, incurved ; hymenium convex, 

 pulverulent, buff-pink at first, becoming deep olive-buff in the 

 herbarium, the margin paler; in structure 500-1000 /n thick, 

 composed of densely interwoven, hyaline hyphae 3 /x in diam- 

 eter, granule-incrusted and with the granules crystalline and 

 sometimes up to 12 /* in diameter but not so numerous as to 

 conceal the structure of the fructification; paraphyses hya- 

 line, filiform, flexuous, often moniliform, 4^J /x in diameter; 

 basidia clavate, large, 120x18 /i, with four large sterigmata; 

 spores subglobose with hyaline wall, minutely echinulate, 

 20-27x16-21 II. 



Fructifications 1-3 and 4 mm. in diameter, ^1 mm. thick 

 where not attached, 2 mm. thick where attached.
