Bonjour,Je vous envoie cette Scutellinia, trouvée au début de ce mois sur une branche de Corylus, près de Tregurà (Pyrénées catalanes).
Coupe 5-6 mm diamètre. Poil 1497,7 x 39,8 µm.
Spores 18,1-18,6 x 11,1-12,9 µm.
Paraphyse 211,5 x 3,9 (mi-hauteur) - 8,4 µm (sommet), cloisonnées.
Asques 228,5-246 x 16,7-18,9 µm.
Je pense qu'elle peut s'agir de Scutellinia scutellata.
Merci beaucoup pour votre aide,
Andrés Valverde Valera

Re : Scutellinia cf scutellata
I'm certainly no expert in this matter but I thought I'd open the discussion.
Your spores' Q seems to be 1.4-1.5. It is the same as in my collection that I think is S. crinita and your measurements are also similar. Q for S. scutellata should be 1.6 or bigger according to the key I was hinted at here before.

Re : Scutellinia cf scutellata
The ornamentation of the spores in Cotton blue and a view of the hair roots would help us to confirm or reject your suggestion

Re : Scutellinia cf scutellata
Thanks you Juuso and Malcolm.
I'm going to make a preparation in Cotton blue in a few days and I will get a picture of the hair roots.

Good morning,
I add some pictures of the spores in Cotton blue and of the hair roots.
I wish they could help to determine the species.
