Terrestric Cheilymenia with stellate hairs
Zuzana Egertova, 08-10-2017 14:01
Zuzana EgertovaHello,
this fungus was found in Svaneti (Georgia, Caucasus), in altutitude 1470 m asl., on soil with moss.
In the first moment, I though it was Cheilymenia crucipila, but spores are smooth.
Apothecia up to 2 mm broad, sessile, orange, with brown hairs on the margin and the outer surface.
Asci 8-spored, uniseriate, non-amyloid, 225-260 x 12.5-15 micrometers.
Spores 16-19 x 8.5-9.4 micrometers, ellipsoid, smooth, with 1 nucleus (4 micrometers across), sometimes with a mucilagenous sheath.
Paraphyses straight, septate, containing orange pigment, 3.5-4.5 micrometers broad, apex up to 6 micrometers.
Excipulum consists of globose, subglobose or angular cells up to 78 micrometers long.
Lateral hairs brown, septate, up to 830 x 26.5 micrometers, mixed with stellated hairs.

Beside Cheilymenia crucipila, I considered C. stercorea f. alpina, which is, however, a typically dung-inhabiting species. There are many cow pastures near the locality, so it´s possible the place was polluted with excrements some time ago.
Other 2 species in the ser. Cheilymenia also don´t fit - C. asteropila (terrestric) has smaller spores ornamented with fine warts, C. parvispora has even smaller spores and grows on dung.
Any suggestions?
Thank you, Zuzana

Re : Terrestric Cheilymenia with stellate hairs
Hi Zuzana,
in my opinion is this already Ch. stercorea f. alpina. The substrate sometimes is not to be recognized any more or it suffices only a little bit soaked ground. Macroscopically striking the long hair with the big distances on the margin.
Greetings Peter.

Re : Terrestric Cheilymenia with stellate hairs
Thank you very much, Peter, I also think Cheilymenia stercorea f. alpina is the best option.
Best regards,
Zuzana
