I found these black pyrenos a few days ago growing on a decidous twig (possibly Sorbus).
Asci 8-spored, IKI negative. Spores hyaline, two-celled, muriform, measuring 25.9 - 36.7 × 7.7 - 9.7 µm.
Any idea what the species/genus might be?

Re : Pyreno with muriform spores
Bonsoir,
Avec ces spores et l'hôte, je pense à Dothidora pyrenophora.
Amitiés,
Elisabeth

Re : Pyreno with muriform spores
That does seem to fit quite well. Thanks! Merci beaucoup.
