Fructification effused, dry, adnate, drying light pinkish cin- 

 namon (exactly avellaneous of Saccardo's ^Chromotaxia^), the 

 margin concolorous, determinate; hymenium even, pulveru- 

 lent ; in structure 120-200 /x thick, with the hyphae 2-2% m in 

 diameter, hyaline, not incrusted, not nodose- 

 septate, running longitudinally and crowded 

 together along the substratum, densely inter- 

 woven in the subhymenium; no cystidia; 

 spores olive-buff in spore collection, only 

 slightly colored under the microscope, even, 

 7-8x6 /x. 



Fructification 3-5 cm. long, 1-3 cm. broad. 

 On decorticated coniferous wood. New York and Ohio. 

 April and August. 



0. avellanea differs from all the preceding species by its 

 avellaneous color, closely adnate habit, thin and dense struc- 

 ture, fine hyphae, and nearly subglobose, slightly colored 

 spores. C. Harperi is of nearly the same color, but has a 

 loosely interwoven subiculum next to the substratum, coarser 

 hyphae, and smaller spores.

 drying pinkish tan, brittle, not strongly at- 

 tached to the substratum, the subiculum and 

 x;^ margin whitish, floccose; hymenium even,

c. Harperi. composcd of loosely intcrwovcn, suberect, 

 Spores, h:^hae. hyaline hyphae not incrusted, not nodose- 

 septate, 3%-5 IX in diameter; no cystidia; 

 spores slightly colored, even, sometimes slightly subangular,
