Very small (~0,5 mm) white ascos, found yesterday
We have found this on deciduous wood, probably Fraxinus excelsior, in Norway.Diameter 1 - 2 mm.
Asci with many spores.
Asci 54-75 x 15-20 my.Spores, hyaline, 15-20 x ca. 2 my.
We hope to get a name.

Hi,
Alnus possible ?
Alain
Try to give more informations, please.
For example, how is formed ascomata ? You can show a vertical section, it's not difficult, and it could bring informations.
And concerning asci, tell us if they are unitunicate or bitunicate ?
More informations you will give, easier you will have a name.
Alain
My idea was Ditopella ditopa.
But check if ascospores could be one-septate, if width is more than 2µm, if asci are unitunicate.
You can use red congo, useful with Diaporthales.
Alain
Then your name, Ditopella ditopa, should be accurate.
