Sclerencoelia on Fagus?
Manak Roman, 21-11-2023 19:29
Hi all,in July I found these apos (max. diameter 6 mm) that look like Sclerencoelia fascicularis on thinner fallen Fagus branches. This one is said to grow only on Populus spp. Do you think it could be it? Spores are 12,7 - 16,5 x 3,1 - 4,0 micrometers.

Re : Sclerencoelia on Fagus?
On Populus, which is what I considered when seeing the bark, I only expect the nor uncommon Sclerencoelia fascicularis. I see no reason to doubt. The excipulum must be of isodiametric cells (globulosa-angularis).

Re : Sclerencoelia on Fagus?
Thank you. I'm pretty sure it's a Fagus twig. It was a pile of pruned branches, but I'll check again the next time I visit the site. I know the area very well, and there's no Populus within half a mile.

Re : Sclerencoelia on Fagus?
Hi Roman, 

you can try a cross-section of the wood. Fagus has thick radial rays (also conspicuous in tangential section), Fraxinus is ring-porous, Populus is diffuse-porous with rather small pores.
