Melanomma subdispersum

Alain GARDIENNETBonjour,

Quelqu'un parmi vous connait-il bien Melanomma subdispersum ?
Does somebody well know Melanomma subdispersum ?


Ce champignon est donné usuellement  sur Betula, mais a déjà été observé aussi sur Sorbus.

Les spores que je vous montre sont celles d'une récolte personnelle sur Sorbus aria. Elles mesurent 22-26 x 8-10 µm. Reconnaissez-vous Melanomma subdispersum ?

Re : Melanomma subdispersum
Hi Alain,

I need the macroscopical appearance to say something :)

The spores does not look like those from M. subdispersum, but from Hysterium pulicare.

You should also compare with my finding on Funghiparadise (M. subdispersum and H. pulicare).

regards,

Re : Melanomma subdispersum
Hi Bjorn,

It isn't Hysterium pulicare (that I have seen many dozen of times, indeed) . It's a Melanomma species, ascomata are subglobulose.
It's very probably M. subdispersum but I just would like the opinion of a body who has already worked it. The ascospores are perhaps slightly different, I don't know (and substrate is not Betula).
Thanks,
Alain

Re : Melanomma subdispersum
Hi Alain,

compared with my finding on Betula, with only slightly 2-coloured spores, I do not think that your collection is M. subdispersum.

regards,
björn

Re : Melanomma subdispersum
Hi Björn,
It was my opinion. I suppose that your ascospores are more constricted, especially at primary septum ?

It could be another species. But which one ?
