 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 tx 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 hy]:)hae 4-4 1^ \l in diameter, not incrusted, and occasional 

 gloeocystidia ; gloeocystidia flexuous, up to 60 X 43^-5 ^ji.; 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 [x, 

 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.
