White Scutellinia

Two previous posts about a White Scutellinia both turned out to be Paratrichophaea boudieri but this time I am sure that this is a Scutellinia.A group of four or five specimens found in damp soil at the edge of a ditch.
With hairs up to 1650 and spores averaging 18.47 x 11.43 with low merging ornamentation it looks right for S scutellata rather than S crinita.
I then noticed one specimen with no orange pigmentation. Having been fooled before an examination showed similarly ornamented spores and no bulbose base to any of the hairs.

Re : White Scutellinia
Hello Mal.
Sometimes certain Apothecia are depigmented in Scutellinia; it may be this is the certain growing conditions. I never met apothecium entirely white, but very clear; essentially S.crinita.

Re : White Scutellinia
Thanks Michel. Schumacher has S scutellata with hairs 360-1600 and S crinita 300-900 but up to 1440 as some were up to 1640 that was why I suggested S scutellata. Is it the shape or ornamentation of the spores that makes you choose S crinita?

Re : White Scutellinia
I think the ornamentation corresponds better to S.crinita; deS.scutellata that is normally coarser.
