Ascobolus on raccoon droppings
Ethan Crenson, 20-05-2019 22:07
In New York City on what I believe are raccoon droppings.  This appears to be Ascobolus sp.  The small orange cups are fringed at the margin and appear to be sessile.  Asci 137-187 x 13.8-17.5µm. IKI-  Spores, when mature, purple brown with longitudinal anastomosing striations 16-17.5 x 8.5-9µm.  Paraphyses occasionally branched, septate.  Excipulum textura globulosa/angularis.  Perhaps the apothecia were not sufficiently ripe, but is it possible to know what this is?  Thank you in advance.

Re : Ascobolus on raccoon droppings
It looks like Ascobolus michaudii

Re : Ascobolus on raccoon droppings
Thank you, Jacky.  I am having some difficulty understanding the finer points differentiating A. lignatilis, foliicola, furfuraceus, michaudii.  In another post on the topic on this forum François Valade comments that the brown walled excipulum cells (in michaudii & lignatilis) vs. hyaline or yellow cells (in foliicola)--but I'm not sure I'm translating these concepts properly. At any rate I have made more images, including more mature apothecia, mature spores and excipulum.  Spores at maturity seem to be quite reliably 16-18 x 9µm, brown, with some branching grooves--even some that connect laterally. Q=1.93  The apothecia only reach 3-4 mm in diameter.  Perhaps there is more detail here that could confirm A. michaud?
