indet. Rutstroemiaceae sp. on unk. fallen leavesMc
I could need help with this pyrenomycete on deciduous wood (Collector says Rhododendron ferrugineum).
Description: Perithecia immersed in the bark, with ostioles just visible as small dots breaking through the surface. Perithecia globose to slightly flattened, around 0.2 mm in diameter with a cylindrical to rounded ostiolar neck of usually 80-150 µm in height. Asci 70-85 x 16-18 µm, with apikal apparatus well visible in Kongo (see photo), 8-spored. Paraphyses not observed. Spores 12-15 x 5.5-6 µm, ellipsoid, hyaline, thin-walled, one-celled, without oildrops.
Thanks a lot for any suggestions

You should find something here : http://www.cybertruffle.org.uk/cyberliber/59350/0062/002/0378.htm

EDIT:
You should check if there is a gelatinous cap around spores in Indian Ink and see if ascus are bitunicate or not (it seems to be unitunicate on your photos, and if it is, it can't be B. vaccinii).
Thanks a lot for the Input and Literature link. I just checked in Indian ink and did not observe a gelatinous sheath. I would clearly tell the Asci to be unitunicate.
I will take a closer look at the M.E. Barr Article

Ce spcimen est à chercher dans les Diaporthales et probablement
dans le genre Sphaerognomonia.

Merci bien. J'ai aussi arrivé au Gnomoniacées lorsque j'essaye d'identifier moi-meme. Je vais regarder le genre Sphaerognomonia.
