Ascocarp Morphology. Ascocarp subglobose or globose, orifice or cavity present, 1-3.5(-5) cm in diameter, orange or yellow (yellowish-brown) or ochre or brown (yellowish-brown), smooth, peridium glabrous or scabrous (papillose), color of spore-bearing tissue yellow or brown (yellowish brown, brown), veins large and rare (arise from the base and radially arranged). Peridium 200-350 micron, outermost layers 30-40 micron, hyaline or yellow-brown, anatomical structure pseudoparenchimatic with roundish cells, cell tangential dimension 8-15 micron, cell radial dimension 8-15 micron, innermost layers 160-320 micron, color hyaline, anatomical structure plectenchymatic, external cystidia absent.
Asci ans spores Morphology. Asci globose, major axis 95-135(-180) micron, minor axis 85-105 micron, number of spores per ascus (1-)3-5(-6), irregularly clustered.
Spores ellipsoid, major axis 28-31-35 micrometer lenght, minor axis (20-)22-25-28 micrometer lenght, color yellow or pale brown (yellowish-brown, brown), reticulation; mesh width 3-6 micron; number of meshes along the major axis 3-4.
Distribution. Habitat temperate; Putative plant host Quercus, or Fagus.
DNA polymorphism. ITS restriction pattern with EcoRI 50-100 bp, or 250-300 bp; SphI 100-150 bp, or 200-250 bp; HincII 350-400 bp; DNA sequence ID of the ITS1-5.8S-ITS2 regions AF073509.
