32 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
petioles, and on rotting wood. West Virginia, Arkansas, Louisi- 
ana, and the West Indies. July to December. 
А. muscicolum has so many tough, stellate organs that it is 
not easy to cut sections free hand which are thin enough to show 
elearly the details of the hymenium; it differs in this respect 
from А. cervicolor and also by the very numerous, branched rays 
and the thicker-walled spores covered with stouter and more 
numerous spines.
