Hysterographium or Gloniopsis?
Lepista Zacarias, 23-04-2016 00:34
Hello everybody,
Same days ago I found a specimen similar to this one but I could not observe it in detail because the lirellae were brittle. It seemed similar to hysterium, but the spores were clearly muriform. Today I found a specimen in better condition and I could observe it better. I attach some photos of the microscopy. For the spore obtained the following dimensions:
(28.9) 32 - 42.8 (45.2) × (11.3) 13.7 - 17.7 (19.7) µm
Q = (1.9) 2.1 - 2.7 (2.8) ; N = 35
Me = 37.5 × 15.8 µm ; Qe = 2.4
I think it can belong to one of the genera Hysterographium or Gloniopsis, but maybe there are other possibilities. Can someone help with the classification?
Thanks in advance,
zaca

Hi Alain,
In fact, from what I saw at the AscoFrance database, Hysterographium fraxini is the most similar, but I don't know these genera and similar ones could exist.
Thanks, Alain, for your proposal.
Best regards,
zaca

Thanks, Alain,
for remind me this link that I knew but forgot to consult this time. It seems that this specimen fits very well in Hysterographium fraxini.
Best regards,
