Rosellinia corticium... or aquila?
Ethan Crenson, 26-05-2016 04:26
Hudson Valley, New York, Dutchess County.  Substrate unknown hardwood.  This Rosellinia has a dense brown subiculum.  Stromata are about 1mm.  Asci: approximately 130-175 by 17-20.  Spores are brown: 24-31 by 8-10.  Apical apparatus: 8-11 by 4-7 and blue in Lugol's.  Germ slit full length of the spore, or nearly so.  Hyaline appendage at both ends of some of the spores. 

Rosellinia corticium? or Rosellinia aquila?  Can someone help me understand what differentiates the two?

My thanks in advance.
