Discostroma sp. on Salix caprea
Gernot Friebes, 17-04-2016 17:48
Here's another difficult fungus (at least for me). I collected it on a dead branch of Salix caprea about 1,5 m above the ground. It should be a Discostroma but I didn't find a species that fits well enough. Ascospores are hyaline, 3-septate (only transverse septa), and measure about 14,4–17 x 6–6,5 µm. There is also an asexual state on the same branch which might belong to the same fungus? As always I'm thankful for any ideas and suggestions!

Best wishes,
Gernot

Re : Discostroma sp. on Salix caprea
Hi Gernot,
I guess you checked Brockmann's work (1976), with no avail.
There is something a bit similar with appendaged conidia described from Japan by Hatakeyama & Harada (Mycoscience 2004) but it was from Paeonia, and ascospores are narrower and more fusiform. Your fungus on Salix is likely something different.
Hope someone will propose a better suggestion.

Cheers,

Jacques

Hi Jacques,

many thanks again. I have checked these publications but to no avail. I will now forward the collection to someone interested for further studies!

Best wishes,
Gernot
