Ostropales (?) with muriform ascospores

Bonsoir,

Apothécies de 0,3-0,8 mm, érumpantes, sessiles, cupuliformes, brunes.

Sur écorce de Quercus pubescens, en compagnie de Proliferodiscus tricolor.

Ascospores : 19-24 x 6,5-8,5 µm, Q. 2,3-3, fusiformes, avec 4-7 cloisons transversales et 1 cloison longitudinale, hyalines, garnies de guttules, lisses.

Asques : 70-80 x 14-17 µm, claviformes, contenant huit spores bisériées. IKI+.

Paraphyses : moniliformes, septées, larges de 1,5-3,5 µm, garnies de guttules jaunâtres, avec un exudat brun au sommet.

Je suis incapable de dire si cette espèce est lichénisée... Je pense à une Ostropales. Merci d'avance pour votre aide !

Hallo. To me it looks lichenized, probably Gyalecta truncigena, a widespread epiphyte on weathering bark, often on Quercus. Zdenek

Hi Andgelo

if you send me a photo of the Proliferodiscus with its collection data I would include this find in my paper. The asci were amyloid?
