Found recently in a New York City park. It appears to be a Tympanis sp., erumpent through fissues in the bark of a hardwood branch (possibly Quercus or Liriodendron tulipifera). The fertile surface is black and the margin and outer surface is pruinose with powdery granules. Asci measure approximately 103-162 x 15-25µm. The contents of the asci are very confusing, ranging from tiny granules to larger globose forms and other blobs. I thought I detected some hyaline allantoid spores with oil droplets at the ends, but I'm not sure they belong to this collection. They measured 3-4 x 1-1.5µm. Is it possible that this is Tympanis conspersus?
Thank you in advance.
