Trouvé sur feuilles mortes de Calluna vulgaris (Lande subalpine xérophile à 1'950m), apothécies 03.-0.5mm de diamètre, surface externe couverte de poils bruns, Hyménium gris, asques 80-115x11.5-12.5µm, octosporés, IKI-, spores fusiformes 45-50x2.2-3µm, lisses, hyalines, 7x septées, paraphyses filiformes.
Qu'en pensez-vous ? Merci d'avance.

Re : Durandiella calluna
The excipular structure with covering intricate brown hyphae looks exceptional. You don't have a closeup of this?
D. callunae is described with 38-52 x 3-4 µm spores and longer asci. No intricate hyphae on the excipulum and that of margin strongly protruding.
I am not sure about this, but also Godronia seems to be excluded.

Re : Durandiella calluna
Jawohl! Now I am convinced it is G. callunae.
The drawing by Müller & Schläpfer-B. is quite schematic, but conidial size and septa fit perfectly (17-22 x 3.5-4).
Du hast kein Foto reifer Konidien?
protologue below.
