menium and subhymenium but giving the color to the fructi- 

 fication, composed of densely interwoven, distinct hy])hae 3-33^ (x 

 in diameter, not incrusted, not nodose-septate; no gloeocystidia; 

 spores hyaline, even, 3-4i/^ X 2-234 [^> copious. 



Fructifications 1-8 cm. long, 1-2 cm. wide. 



On bark and decaying wood of frondose species. Alabama, 

 Louisiana, Nebraska, and Brazil. May and June. 



C. subochraceum occurs on decaying frondose wood and bark 

 in closely adnate, thin fructifications of wood-brown color due to 

 the pale color of the superficial tissue. The spores were published 

 by Bresadola as 6-8 X 4-4}^ [i and the hyphae as conglutinate, 

 but in the original specimen from Bresadola the spores are copious, 

 flattened on one side, and not larger than 4}/^ X 23^2 t^ and the 

 hyphae not conglutinate. 



Specimens examined :

98. C. canadense Burt, n. sp. 



Type: in Burt Herb., Mo. Bot. Gard. Herb., and N. Y. State 

 Mus. Herb. 



Fructifications broadly effused, adnate, rather thick, mem- 

 branaceous, small pieces separable when moistened, light buff, 

 even, ceraceous, cracking but little in drying, the margin narrow, 

 sulphur-yellow, with its hyphae interwoven ; in section 600-800 ^ 

 thick, colored, stratose, the buried strata becoming fuscous; 

 hyphae of each stratum 3 (x in diameter, not incrusted, occasion- 

 ally nodose-septate, erect, loosely arranged below, forming a 

 compact hymenium; no gloeocystidia; spores white in spore 

 collection, cylindric, even, 43/2~6 X 13^-2 [x. 



Fructifications 3-10 cm. long, 1-5 cm. wide. 



On decaying wood of logs of Pinus Strobus. Canada and New 

 Hampshire. July to September. Rare.
