74. C. vesiculosum Burt, n. sp. 

 Type: in Burt Herb. 



Fructifications broadly effused, closely adnate, thin, between 

 ivory-yellow and cream color in the herbarium, waxy, even, not 

 cracked, the margin thinning out; in section 150-S40 \l thick, not 

 colored, somewhat stratose, with the 3 strata or layers of the 

 type separated by narrow zones of hyphae glued together; hyphae 

 about 2 [l in diameter, thin-walled, collapsing, poorly defined, 

 densely interwoven; gloeocystidia up to 40 X 8 ;*; many vesicular 

 bodies, presumably gloeocystidia, are present and are 5-7 \i in 

 diameter also larger vesicular spaces; spores hyaline, even, 

 4-8 X 23^-4 [l, borne on protruding basidia having 4 sterigmata. 



Fructifications in fragments up to 4 cm. long, 1% cm. wide. 



On decaying, frondose wood. Canada and New York. Oc- 

 tober. 



C. vesiculosum is colored like C. radiosum but is closely adnate, 

 does not have a radiating, fibrillose margin, and has smaller 

 spores. 



Specimens examined: 

 Canada: /. Macoun, 71, type. 

 New York: East Galway, E. A, Burt 



75. C. globosum Burt, n. sp. 

 Type: in Mo. Bot. Gard. Herb. 



Fructifications effused, thick, adnate, spongy-soft, white, 

 becoming cartridge-buff, somewhat granular, not waxy, cracked 

 only rarely, the margin determinate, thick, with hyphae inter- 

 woven; in section 600-700 n thick, grayish olive near the sub- 

 stratum, stratose, each stratum composed of slightly colored, thin- 

 walled, suberect, curving and branching hyphae 3^-1 (x in di- 

 ameter, and of scattered, conspicuous, rather thick-walled, glo- 

 bose vesicular bodies 12-13 (j. in diameter; no other gloeocystidia; 

 no cystidia; spores hyaline, even, 3x2^.. 



Largest fragments of fructifications are 3 cm. in diameter and 

 4 cm. long, 2 cm. wide. 



On rotten frondose wood. West Indies. November. Prob- 

 ably local. 



C. globosum forms thick, pulvinate fructifications suggestive in
