BURT THELEPHORACEAE OF NORTH AMERICA. VIII 257 



Fructifications up to 3-8 cm. long, 2-4 cm. broad. 



Under rotting pine boards and limbs on the ground. New 

 York, Maryland, and Washington. October to December. 

 Probably rare. 



This species is characterized by its dark color — usually 

 olive-brown — dark-colored hyphae, and very large, septate, 

 colored, incrusted cystidia. Our American specimens agree 

 well with that from Europe received from Bresadola, whose 

 view of this species I follow.
