Enrique RubioI need your help with this pyreno with small (o.2-0.3 mm)pyriform, caespitose, ostiolate, papillate, not setose, blackish, pseudothecia on a branch of harwood still attached to the tree. It has paraphysate ascomata KOH-negative, with bitunicate asci and the ascospores (hyaline or very pale pinkish), with no sheaths,have several transverse septa. 
Maybe a Pseudotrichia species?
Many thanks in advance.

Re : On bark
Hello Enrique

Do the perithecia collapse when dry? This is somewhere in the Tubeufiaceae, I think; it more or less matches Thaxteriella pezizula apart from the lack of a subiculum (conidiophores). I dug around a little in the family but couldn't find a clear match. Keep on searching...

Best wishes

Paul

Re : On bark
Dear Paul
Thank you for your replay.
In fact, as you expected, the ascomata collapse vertically when they dry out. But I haven't been able to see any remains of any hypomycete under them.
However your proposal of Tubeufiacieae seems correct and so I have been consulting even Thaxteriella could be a good genus.
Enrique
