Re : Asco sur feuilles pourries de ronce (Rubus)

looks like Fuscolachnum. I do not have the time to look if it ist misellum or dumorum (not by heart in my brain).


Best, Lothar

Yes, it is F. misellum (F. dumorum is a Brunnipila).

There is a tendency of atlantic finds to have shorter and narrower spores, see my folders.

A spore width of 3 µm is probably very exceptional if not wrong?

Great thanks Lothar and Zotto !

For the spore width, I'll check but I think it was one big spore.

Re : Asco sur feuilles pourries de ronce (Rubus)

If I remember correctly, it is the paraphyses that differentiate F. misellum from B. dumorum. As they are cylindrical and narrow, it corresponds to F. misellum.


But what separates Fuscolachnum from Brunnipila, only the paraphyses?


Best regards,


Daniel

Re : Asco sur feuilles pourries de ronce (Rubus)
No, also the hairs are different. Fuscolachnum has slightly flexuous hairs without swollen tip, but Brunnipila straight hairs with a slightly bulbous tip. Also the hairs are densely septate near the apex only in Brunnipila. Usually they bear crystals, but I never saw them in B. dumorum.  I must admit that the hair differences are not sharp because of variability. However, sequences show that B. dumorum is misplaced in Fuscolachnum, while supporting my idea of a Brunnipila.

Re : Asco sur feuilles pourries de ronce (Rubus)

Thanks a lot for these clarifications Zotto.


F. misellum seems quite commun here in Belgium, but I will check more carefully next time to see if I could find B. dumorum too.


Best regards,
Daniel

Bonsoir Daniel,

Je me rends seulement compte maintenant que tu l'avais bien repérée le 06 octobre dernier.

Je suis retourné dans le site où je l'ai trouvée à mon tour…… :o)

Amitiés,

Bernard
