Boule noire sur mousse. Dothideo ?

Adio à tous,Par simple curiosité, j'aimerai mettre un nom sur cet asco.
En fouillant à la loupe binoculaire, à la recherche de Lamprospora, je vois des petites boules noires, posées au milieu des petites pousses de mousses (non déterminées).
Je passe au microscope.
Données : Asques, crochets, IKI-, base courte
Spores : une cloison, resserrées à la cloison, 2 guttules (ou plus) de chaque côté de la cloison, avec une probable gaine peu visible autour. 20-26 x 4.5-6 µm
Le reste en photos.
Je suis désolé, je ne sais pas quoi regarder d'autres et je l'ai observé par curiosité.
Merci d'avance,
Beñat

Re : Boule noire sur mousse. Dothideo ?
Hi Benat,
this is a Bryostroma, perhaps B. axillare. It occurs on the top of various mosses, especially on Pottiaceae. However, it is mostly recorded during the search for other, bigger ascomycetes growing on or between mosses. Here are some photos for comparison.
Can you show us a photo of the spores in IKI?
regards,
björn

Adio Björn,
And thanks. I have suspected Bryostoma but I know nothing...
Some other photos and détails :
Perithecium is totally roundish, without an apical pointed end.
Measurement : around 200 µm in diameter.
Some little "hairs" are visible... I don't know if the term is good for this genus.
