Eutypella on Hibiscus syracus
Björn Wergen, 09-03-2011 13:50
Björn WergenHi,

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

Re:Eutypella on Hibiscus syracus
Perhaps E. scoparia ?

Hallo Kazuya,

Look here:
http://www.ascofrance.com/index.php?r=forum&page=viewtopic&id=14457

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,
Kazuya

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).
