Ca fait penser à Velutarina rufoolivacea..
Gilbert
Indeed my idea was a Cenangiaceae, and Gilbert may be close to the truth.
Do you have photos in water also? This would be very important because Velutarina, as many Cenangiaceae, have a refractive vacuole in the paraphyses. Velutarina survives in the herbarium for several weeks, so you might still be able to verify this.
Did you test iodine for the asci?
What I miss are the large scattered green excipular cells typical of Velutarina.
Zotto
Thank you for the comments. Unfortunately, this was only mounted in 10% KOH, and I am unaware whether or not it was deposited in Peru, or dried and sent elsewhere. I can ask the faculty from the course, but I do not have high hopes :(
I don't suppose the warted spores are diagnostic in any way, are they?
-Danny
V. rufoolivacea ejects hyaline spores which later get brown and warted, though not so coarsly.
But the maturity of the spores is impossible to clarify in a KOH mount.
