BURT—THELEPHORACEAE OF NORTH AMERICA. VIII 257 
Fructifications up to 3-8 cm. long, 2—4 em. 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.
