Re : unknown discomycete from Peru
This looks like an Encoelioid discomycete.

Bonsoir,
Ca fait penser à Velutarina rufoolivacea..

Hi Danny et al.

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.

Re : unknown discomycete from Peru
Hello all,

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?

Re : unknown discomycete from Peru
This is a great pity, such splendid photos and no possibility to check important characters. One such character of V. rufoolivacea would be the simple-septate ascus base.

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.

Re : unknown discomycete from Peru
I have written the faculty to see if they know the whereabouts of the material.  Fingers crossed!
