 268 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



Fructifications broadly effused, adnate, rather thick, mem- 

 branaceous, separable when moistened, vinaceous-buff or pale 

 avellaneous when fresh, becoming deep purplish vinaceous where 

 bruised, finally between pale olive-buff and pale pinkish buff in the 

 herbarium, even, waxy, not cracking, the margin whitish, fimbriate ; 

 in section 150-450 \l thick, pale-colored, with a compact hymenial 

 layer containing numerous thin- walled, vesicular bodies 15-75 X 

 12-45 {jl, and with a very broad supporting layer consisting of thin- 

 walled, nodose-septate hyphae 2-3 y. in diameter, not incrusted 

 and loosely arranged except in thick fructifications where 1 or 2 

 dense narrow zones are present between substratum and hy- 

 menial layer; basidia 2-spored; spores white in spore collection, 

 even, subglobose, 6-9 X 5-7 y., slightly pointed at the base. 



Fructifications 3-9 cm. long, lJ^-3 cm. wide. 



On bark of fallen trunk of Abies rubra and Tsuga canadensis. 

 Vermont to Wisconsin. September and November. Rare. 



C. vinososcabens dries a characteristic livid color, occurs on bark 

 of conifers, and has large subglobose spores and a vesiculose hy- 

 menial layer. These vesicular organs are presumably gloeo- 

 cystidia but so highly inflated that they appear empty under the 

 microscope, and with their scanty cell contents adhering to the 

 cell wall.
