Hello, bonjour.Here is the paper I'm searching for
Eutypella on Hibiscus syracus

I'm sorry to ask so many things here but there is one more problem. There was no much work to find more pyrenomycetes, and so i find something strange on a Hibiscus syracus, a Malvaceae in my garden. I think it should be Eutypella spec., but I am not sure. Perhaps you can look at the photos and help me with determination ;)
Ascomata is a stroma embedded into the wood with a few scattered perithecia, with a 0,5 mm long neck (see photos, resembling some Diaporthe-species).
Spores 4-6,5x1-2µm, allantoid, pale brown, smooth. Asci with a long stalk, with 8 spores, 35-45x4-5µm.
The strange thing is the substrate: Hibiscus syracus. Did someone know about a Diatrypaceae on Hibiscus?
regards and thanks again,
Kazuya

Perhaps E. scoparia ?

Hallo Kazuya,
Look here:

With the little spores, it should E. scoparia be.

Re:Eutypella on Hibiscus syracus
arrrr I also thought about scoparia but what about the long necks?^^
ok it seems as if E. scoparia has a high macroscopic variability...i didn't find this Eutypella before.
thanks and regards,

Re:Eutypella on Hibiscus syracus
E. scoparia has a well-known macroscopic variability. Robinia is a good substrate to find it (generally with long necks on it). But it has already been found on Hibiscus syriacus in Italy (dixit Rappaz).
