Scutellinia olivascens?
William Slosse, 14-03-2020 19:01
William SlosseDear Forum,

yesterday I found in the garden in a hollow in the trunk of a Populus alba some Scutellinia.
Using the Jeannerot key (2019) I think this might be S. olivascens.

Apothesia: up to 5.5mm diameter;


Marginal hairs: with multifurcate base; up to 940um long & 35um wide;


Spores: Qav = 1.40 (N = 14); ornamented with clear visible warts; no ridges

Am I right?

Regards,

William

What size were the spores?

With my excuses, Malcolm:
Av = 19.01 x 13.51

Re : Scutellinia olivascens?
That fits well with S olivascens. The “S” shaped hairs are also a helpful indicator.
