Strossmayeria ?
Ethan Crenson, 29-08-2019 19:04
Hello all,

Recently I found this tiny discomycete on rotted hardwood in the Eastern US.  It is white, discoloring to amber/orange, cushion-shaped, perhaps with a pseudostipe or narrowing at the point of attachment.  Asci 120-150 x 12-14µm, IKI-.  Spores very guttulate, 5-8 septate, 32-50 x 4-5µm.  Paraphyses with irregular, swollen tips about 4-5µm wide at the widest point.  One thing I noticed is that the base of the excipulum stains blue-green in iodine.  This combination of features seems very similar to discussions of Strossmayeria basitricha I have read on this forum-- especially an exchange from April 2015 between Enrique Rubio and Zotto. Is this S. basitricha? Many thanks in advance.

Ethan

Re : Strossmayeria ?
Yes, it is a Strossmayeria and possibly basitricha - the species concepts in this genus are dubious to me. I think the anamorph you also have, it is always there.

Re : Strossmayeria ?
Thank you Zotto!  Would an examination of the features of the anamorph help to determine a species ID?  Or is the anamorph not useful?
