 260 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



Specimens examined : 

 North Dakota: Brenckle, comm. by V. Litschauer, 1, type. 

 Oregon: Corvallis, S. M. Zeller, 2219 (in Mo. Bot. Gard. Herb., 



63029). 



70. C. protrusum Burt, n. sp. 

 Type: in Mo. Bot. Gard. Herb. 



Fructifications broadly effused, rather thick, dry, felty-mem- 

 branaceous, separable, drying between light buff and cream color, 

 even, conforming to irregularities of the substratum, not cracked, 

 the margin a little paler than the hymenium, thinning out, with 

 the hyphae interwoven; in section 500 \l thick, not colored, 2- 

 layered, with (1) a broad layer next to the substratum of very 

 densely and longitudinally arranged hyphae, and with (2) a 

 somewhat more loosely arranged layer of interwoven, suberect, 

 hyaline hyphae 4-4J^ y. in diameter, not incrusted, and occasional 

 gloeocystidia ; gloeocystidia flexuous, up to 60 X 43^-5 [l; basidia 

 4-spored, not side by side and adhering together in a compact 

 palisade layer but very numerous and protruding individually 

 6-15 [i; spores attached to basidia are hyaline, even, 6 X 23^-3 [a, 

 tapering towards the base, not copious. 



Fructification 6 cm. long, 5 cm. wide, broken off on one side 

 and at one end probably large. 



On bark of a badly decayed frondose log in a moist virgin forest. 

 Mexico. December. 



C. protrusum has a large fructification of general aspect and 

 color of that of C. portentosum and C. galactinum but softer than 

 these, of quite different structure, and having gloeocystidia. The 

 basidia protrude beyond the general level of the fructification in 

 the manner of cystidia; the presence of spores at the apex shows 

 convincingly their real nature.
