Bonjour à toutes et tous,Pourriez-vous m'aider à
minute hairy discomycete from Portugal - Fuscolachnum?
Lothar Krieglsteiner,

some days ago, on the lower surface of leaf of Quercus suber, together with Micropeziza mollisioides and Penicillium aureocephalum, Algarve.The apothecia were not fully ripe and its hairs were agglutinated with amorphous crystals to large extent. The few free spores (quite moving in the slide) were about 5-7/1,5-2 µn large. Paraphyses are filiform and with some guttule content. The asci are (some ..) 8-spored, and I did not find croziers. With Barals solution they react faintlly bluish (hardly to get in the picture). The excipulum is of textura angularis-prismatica, the end-cells (as they could be observed) are about 20-35/3-4 µm long and brownish, they bear protuberances similar to Mollisina but shorter.
Who can help further?
Best regards, Lothar

Hallo Lothar
this must be Graddonidiscus hispanicus, which should have simple-septate ascus base.
Alternatively G. vandae (= Dasyscyphus coruscatus) should be compared, whch has croziers.
See my folders in Hyaloscyphaceae, HB 7466, ERD 7054, HB 5199a
