This fungi was on a rotten shrub.
Spores (15.6) 15.9 - 19.2 (19.4) × (3.7) 3.8 - 4.88 (4.9) µm fusoid (not sure but I think amyloid)
They seem to be septate - 1-3 in asci, but outside is difficult to be sure.
They were over a unidentified mass, at first I thought it was a crust.
Can you help me?
Thank you very much.
Elsa

Re : Nectriaceae?
Dear Elsa,
seems to be Hypomyces aurantius.
Do ascomata change color in KOH? check ascospores size outside the asci, with or without apiculi.
All the best,
Christian

Re : Nectriaceae?
Hi dear Christian,
Thanks for answer.
I have no KOH but NaOH, stained like photo.
I don't find description for Hypomyces aurantius. Can you tell me the measure of the expected spores?

Re : Nectriaceae?
Dear Elsa,
there's a description e.g. in Rogerson et Samuels (1993): Polyporicolous species of Hypomyces, online here: http://www.cybertruffle.org.uk/cyberliber/59350/0085/002/0231.htm
Best regards,
Viktorie
