Asexual morph
Gernot Friebes, 05-11-2015 18:19
Hi again,

this curious asexual morph was found on a wet and decorticated Fagus trunk. The conidia are about 9-11 µm long and have three septa. Maybe someone recognizes it. :-)

Best wishes,
Gernot

Hi Gernot,


Perhaps around Helicomina ?

Re : Asexual morph
Hi Gernot
it looks rather like Hyalotrochophora lignatilis (see image, from Seifert et al., 2011) though I'm not sure whether that has been recorded for Europe. Goos, in Mycologia 79: 1-22, (1987) might be useful here . . . .
best wishes
Chris

Re : Asexual morph
Hi Alain & Chris,

Hyalotrochophora indeed cought my eye when looking through The Genera of Hyphomycetes and using the key I also arrived at that genus. I contacted Keith Seifert and he agreed that the morphological similarities to the type and other Canadian collections of H. lignatilis are very high. He also mentioned that it would be nice to compare sequences of this collection with Canadian material to see if they are actually the same species. So I think for now we can assume that this collection is indeed H. lignatilis or a closely related species.

Thanks again to everyone involved!

Best wishes,
Gernot
