Pyreno on Ulmus
Enrique Rubio, 15-04-2021 18:05
Enrique RubioI am very confused about this pyrenomycete growing under the bark of Ulmus minor and maybe someone has a good idea that can help me.
It forms blackish stromata with several deformed perithecia when compressed.
The asci are long, polysporic, without a conspicuous apical apparatus and often strangulate, but the stipes do not appear to be long as in Coronophorales and the spores are small, allantoid and completely hyaline.
Could be Fracchiaea a good genus for it?

Many thanks in advance
