Scutellinia barlae ?

Bonjour à tous,Voici un Scutellinia récolté sur chemin forestier humide. Je pense à Scutellinia barlae.
a) poils à base simple, bruns, septés, à parois épaisses : longueur maximale 900 mu
b) paraphyses à pigment orange, élargies à l'extrémité
c) spores globuleuses à verrues arrondies-tronquées : diamètre 17-19 sans l'ornementation (verrues hautes de 1-1,5 mu)
Qu'en pensez-vous ?

It looks good except for the hairs. In S barlae they should be a maximum of 300. Benat (and Neven?) are in the process of publishing a new species S heterosphaera which has longer hairs (to 870) but the warts on that species are short but a mixture of rounded, truncated and pointed. Your photos do not show exactly what the warts are in profile but I think that is the species you have.

Re : Scutellinia barlae ?
Good evening Malcolm,
A big thank you for your opinion!
I will check again the length of the hairs and try to better highlight the ornamentation of spores. But it does seem to have seen different types of warts as you explain it.

Re : Scutellinia barlae ?
I also think that it's OK to S.barlae

Re : Scutellinia barlae ?
Bonsoir Michel et Malcolm,
Je viens de refaire une préparation :
a) j'ai mesuré 5 grands poils : 820-860-900-900-990-1050 mu de long
b) les spores portent bien des verrues tantôt arrondies, tantôt tronquées, tantôt pointues.
OK pour Scutellinia heterosphaera alors ?

Re : Scutellinia barlae ?
Et j'oubliais de préciser pour les poils : base majoritairement simple, parfois fourchue, rarement multifourchue.

Until the work is published I would be calling this Scutellinia heterosphaera nom prov.
