Re : Pyreno with long spores.

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.

Re : Pyreno with long spores.

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.

Re : Pyreno with long spores.
The spores are 15 - 20 x 3 - 4 my, oneseptate and unitunicate.
Then your name, Ditopella ditopa, should be accurate.
