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?
