This discomycete was growing on fallen twigs (of Quercus or Fagus) in litter in lowland woodland. Details as follows:

Apothecia: creamy white, short-stalked, <1.5 mm diameter, hairy on outer surface and stalks.

Excipulum: textura prismatica.

Asci: 55-65 x 5-6 µm, arising from croziers, apices blue in IKI.

Spores: (8-)9-11(-12) x 2-2.5 µm, with a few small oil bodies at each end.

Paraphyses: broadly lanceolate, multi-septate, no VBs, 60-70 x 5-7 µm, exceeding asci by 5-10 µm.

Hairs: 45-60 x 3-5 µm, hyaline, septate, tapering to apex, smooth, sometimes with oil drops adhering to walls.

I assume it belongs to the Lachnaceae but I'm struggling to put a name to it. I'd be grateful for any help.

Many thanks

Marcus

Re : Lachnaceae? on dead wood

Mi Marcus

exquisite!! 
Colipila masduguana. Do you have my paper on this?

Please lok whether the pores of the wood are large (Quercus, ring-pored) or small (Fagus). Usually it was on Castanea or Quercus. Only known from France so far.
