White Rhytismatales on Salix
Juuso Äikäs, 01-01-2020 18:03
Hello 2020!
I found these things today growing on the trunk of a fallen Salix caprea near a shoreline. Spore size is on average 24 x 6 microns, Qav = 4. Any ideas?

Hi,

check Propolis farinosa.

De acuerdo con Propolis farinosa, dejo un enlace de un trabajo mío de la especie, en mi estudio las esporas midieron(21,8) 24,1;28,1 X (5,1) 6,3;7 micras. 
Saludos.

Re : White Rhytismatales on Salix
Thank you! It must be Propolis farinosa!

Re : White Rhytismatales on Salix
Hi

Due to the fact that other interesting species grow on Salix, a photo of spores in H2O would be appreciated :)
Although I suspect that they would only confirm only P. farinosa :)
