 254 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



thick, pale avellaneous, becoming stratose when old and thick, 

 with a narrow layer of hyphae arranged longitudinally along the 

 substratum and the remainder of the fructification composed, 

 according to age, of one or more strata of erect, agglutinated 

 hyphae, basidia, and gloeocystidia ; gloeocystidia very numerous, 

 flexuous, 60-120 X 4-9 [x; spores hyahne, even, flattened on one 

 side, 4-8 X 3-6 \l, copious. 



Fructifications 4-10 cm. long, 1-4 cm. wide. 



On decaying wood of logs of frondose species. In Europe, 

 Canada to Louisiana, and westward to the Pacific states, in the 

 West Indies, and in Mexico. Throughout the year. Widely 

 distributed but not common. 



C. lactescens is best recognized in thick stratose fructifications 

 by their cracking into short and usually disconnected fissures, 

 stratose and agglutinated structure, occurrence on frondose 

 wood, very numerous gloeocystidia, and rather large spores.
