 248 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



On decaying wood of Quercus and Fraxinus in France, of 

 Quercus in Maine, and of Populus trichocarpa in Idaho. July to 

 October. Probably rare. 



C. analogum has general aspect and color of C. galactinum and 

 C. portentosum and structure related to that of C. effuscatum. 

 The thick, stratose fructifications, containing great numbers of 

 imbedded spores and gloeocystidia, afford good additional dis- 

 tinctive characters. The Maine specimens are doubtfully re- 

 ferred here as a young first-stratum stage. 



Specimens examined: 

 France: Aveyron, A. Galzin, 12485, authentic specimen, coram.

Type: in Kew Herb. 



Fructifications broadly effused, rather thick, membranaceous, 

 small pieces separable when moistened, honey-yellow to russet 

 when fresh, fading to cream-buff in the herbarium, even, pul- 

 verulent, the margin thinning out; in section 200-500 [i thick, 

 composed of very densely arranged, suberect, interwoven hyphae 

 about 2 pi in diameter, gloeocystidia, and chlamydospores; gloeo- 

 cystidia flexuous, 40-150 X 5-9 \k, starting from the substratum; 

 imbedded chlamydospores very numerous, globose, 5-6 [i in 

 diameter, sometimes comprising nearly the whole fructification; 

 basidiospores hyaline, even, 6 [l in diameter. 



Fructifications 3-10 cm. long, 2-4 cm. wide. 



On under side of decaying wood and bark of frondose species. 

 Newfoundland and Canada to Louisiana and westward to 

 Washington. September to November. Widely distributed and 

 common locally. 



C. effuscatum is conspicuous when fresh by its large salmon to 

 brick-red fructifications. It soon fades in the herbarium to the 

 pallid or buff color assumed in the herbarium by many species and
