Hemiamyloid Mollisia on Salix
Juuso Äikäs, 19-04-2021 21:11
Yesterday I found a large group of small Mollisia(?) fruitbodies growing on the top and sides of a fallen, decorticated trunk of Salix caprea.

IKI+(rb), croziers+, pp with VBs, KOH-.

Spores:
(6.5) 6.6 - 7.78 (7.8) × (2.7) 2.73 - 3.06 (3.1) µm
Q = (2.2) 2.3 - 2.76 (2.8) ; N = 10
Me = 7.2 × 2.9 µm ; Qe = 2.5

In Gminder's key the only hemiamyloid Mollisia on wood is M. elegantior, but that one grows on Quercus and the spores are larger.

Re : Hemiamyloid Mollisia on Salix
The guttulate paraphyses exclude a Mollisia. Better would be the genus Pyrenopeziza. Maybe what we call P. aquosa comes close to this, but I do not remember such guttules in the paraphyses.

Re : Hemiamyloid Mollisia on Salix
Ok, thanks. The guttules did disappear with the addition of KOH, so I think they were still VBs(?). But yeah, the paraphyses didn't have the one, long and uniform VB typical of Mollisia.

Re : Hemiamyloid Mollisia on Salix
Of course they disappear, they have not the refractivity of lipid. But SCBs disappear also. Anyway they could be VBs, you need to do vital staining with CRB which stains VBs and vacuoles but not SCBs.
