Micropeziza-like discomycete

Bonjour tous

Clearly not a Micropeziza but the form of the apothecia and the presence of a red-brown crust reminded me of that genus.

Apothecia abundant on decorticated portions of a Salix twig (probably Salix cinerea), small (up to c300µm diameter), sessile, deep amber-coloured, without a distinct margin.
The "crust" differs from that of Micropeziza as it has a more regular appearance forming a sort of lattice (treillis/Gitter/enrejado).
The main body of the apothecium consists of a contorted mass of hyaline cells - see image.
Asci definitely IKI negative, 8-spored; croziers not yet looked for.

Spores hyaline with generally one or two large globules towards each end, 6.2-8 x 2.8-3.5µm.The macro image of the apothecia was taken after they had been kept damp overnight, I shall post more of them without the distracting highlights. In the meantime if these photo's suggest anything I would be grateful. More images will follow  . . .

Amitiés, Chris.

Re : Micropeziza-like discomycete
Hi Chris

would bo good to see living paraphyses regarding VBs.

Did you test KOH for a possible solubility of the red-brown piigment (ionomidotic)?
