Scutellinia olivascens?

Dear 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

Re : Scutellinia olivascens?

With my excuses, Malcolm:
Av = 19.01 x 13.51
Av = 19.01 x 13.51

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