B ShelbourneCudoniella tenuispora: Distinctive macro and habit
pale disc on Urtica stems - S Sweden - with spiralling spores

Apothecia to 0.2 mm, discoid with distinct smooth margin, at first whitish-greyish drying to apricot on hymenium with paler outside.
Hymenium deep orange red in IKI in weak ammonia then slowly blue at the apex and less so further down the asci.
Asci with outer dextrinoid coating, 8-spored, clavate, ca. 50 x 8-9 µm.
Spores strongly spiralling within ascus in one bundle, 3-5- septate, tapering to lower end and rounded at distal end, 35-45 x 1.5 µm. Paraphyses clavate above. Not exc. asci.

Perhaps Erinella discolor = Trichopeziza discolor = Lachnum discolor ??

Re : pale disc on Urtica stems - S Sweden - with spiralling spores
interesting suggestion but this material is without hairs, with paraphyses that are enlarged (pearshaped) at the apices, spores with fewer septa etc.

Re : pale disc on Urtica stems - S Sweden - with spiralling spores
Hi Thomas,
indeed this option seems to be quite unusual without hairs, in my opinion it has a twist of a Lichenicolous species with this apical dome and the asci strongly reacting in IKI, they mostly react blue in this case only a little blue left after a while probably because of the Ammonia mount.
No idea about the genus.
good luck,
Stip
