on standing, dead herbaceous central stems of Pyrularia pubera (see last image)

hymenial surface incrusted with abundant, dextrinoid (?), stellate crystals

Stage micrometer was recently lost, and so sadly I have no measurements at this time.

Re : Pezicula sp. on Pyrularia pubera - North Carolina, USA
I remember to have seen in Pezicula such redbrown granules extruding from the hymenium (paraphyses) when adding Lugol. I assume you used Melzer. Important would be to check a KOH-pretreated probe with MLZ to see the deep blue apical rings (hemiamyloidity!).

For a species name I can say nothing.

Zotto,

Thank you for the reply.  I use Lugol's when working with discomycetes whenever possible, at your long ago instruction, this being no exception.  I made sure that a plentiful supply of it would be available for our participants to use at the Korf Foray and subsequence Purchase Knob AscoBlitz.  One of the same dropper bottles provided for those events was used in the preparation of this sample.

Re : Pezicula sp. on Pyrularia pubera - North Carolina, USA
Great! I concluded from the seemingly negative ascus apex that it must be Melzer. I only remember one species with inamyloid asci - not sure which it was. All others react pretty pure red but after KOH deep blue.
