Nectriaceae?
Elsa Sousa, 28-12-2018 01:11
Good evening,

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

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?

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
