Coprophilous on herbivore dung
Zuidland Peter, 27-09-2021 08:31
Hello all,
I need help with this find on herbivore dung (possum or Koala) in a moist chamber.
Only one apothecium less than (1mm) big enough to sample for microscopy, which was mounted in H2O; a few more much smaller ones may be looked at later (hopefully).

Asci: 94.5 x 9.4um
Spores 0-3 septate, 22.2-29.5 x 3.7-4.4um

Victoria, Australia
Thank you and take care,

Peter

Re : Coprophilous on herbivore dung
Hi Peter

this looks like a Hyaloscyphaceae, perhaps Hyalopeziza. But I cannot exclude an Arachnopezizaceae.

Important is to study the IKI reaction of the ascus apex and the presence of croziers at the base. How large are the hairs (l & w)? Are they thick-walled at the base?

I assume that the spores are forcibly ejected when 3-septate.

Re : Coprophilous on herbivore dung
Many thanks Zotto,

I hope I can get another one for the extra work you suggest; I will have another look at what I have already to see if I can get some answers.

Cheers

Peter
