Bonjour, Je vous ajoute quelques photos d'un dothideomycete (comme m'a dit le camarade Enrique Rubio), que j'ai trouvé le 5 décembre près de l'étang du Banyoles sur bois morte de possible Salix. Les pseudotecia? qui sont tuberculées mesurent 160 ?m aprox. J'ai pu regarder les spores, qui mesurent 14,4 x 4,8 micres.
J'espère que vous pouvez m'aider à déterminer de quelle espèce il s'agit.
Merci beaucoup d'avance,

Re : Dothideomycete
Hi,
could you elaborate a bit on the form of the ascomata? Is it possible that they grow on old stromata of Hypoxylon?

Gernot

Re : Dothideomycete
You think at Immotthia, Gernot, right ?

Re : Dothideomycete
Hi Gernot,
I prefer to send to you a picture that I have just took under the microscope of these ascomata, that are tuber-form, distributed especially in the periphery of the fruiting bodies.
At first I thank in Hypoxylon serpens, for the shape of the mushroom, but I haven't found spores like those of Hypoxylon. Although I have to say that I have found an another kind of spores while searching the asci, that I attach in the second picture.
Best whishes,
Andrés

Re : Dothideomycete
Hi Andrés,
yes, that looks very much like Immotthia atrograna on Hypoxylon sp. On your last photo you show the conidia of this species.

Re : Dothideomycete
Thanks you so much Alain and Gernot!!!
I've seen the subject "sur hypoxylon / 2. pyreno noir" and I also think that I have found the anamorphe (Sphaeropsis parasitans) but I will write only Immothia atrograna bescause I understand that they are their conidia.
Thank you very much for your help! Without you I would never have determined this species. Muchas gracias!!
