Cheilymenia on cow dung
Zuzana Sochorová (Egertová), 22-07-2014 15:41
Zuzana Sochorová (Egertová)Hi,
here is Cheilymenia from Georgia - with the key in Nordic Macromycetes I came to Cheilymenia stercorea (but there are no stellate hairs in my collection+spores should be bigger) and Ch. fimicola (again spores should be bigger).
Apothecia 1-6,5 mm, rounded, sessile, caramel colour (or orange-brownish), margin with dark hairs.
Asci 168-220 x 9,5-10,5 micrometers, not blue in Lugol, containing 8 spores in 1 row.
Spores 14-15 x 6,5-8 micrometers, ellipsoid, biconcave, smooth.
Paraphyses 2,5-4 micrometers, broader at apex (5-7 micrometers).
Hairs 150-820 x 15-37 micrometers, rooting, brown, septate.
Do any other species with rooting hairs exist? Or could it be only variability maybe of Ch. fimicola?
Thanks, Z.

Re : Cheilymenia on cow dung
Zuzana,
you have to observe ascospores in cotton blue to check spore ornamentation. It's important to propose a determination.

Re : Cheilymenia on cow dung
I observed it in cotton blue and it really seems smooth.
