Re:cheilymenia cf pulcherima ?
I agree with Christian. It’s difficult to say without seeing the bases of the hairs and the perispore in coton blue.
I have examined recently material of C. pulcherrima from North-eastern Spain. The apothecia are typically columniform (not discoid) and smaller: the maximum diameter is 0.5 mm. The hairs does not overcome 220 microns, have 3-4 septums, and the bases are simple. The perispore is smooth in coton blue seen under x1000 oil immersion lens.

Re:cheilymenia cf pulcherima ?
Have you consultef the monograph by Moravec: A World Monograph of the Genus Cheilymenia (Discomycetes, Pezizales, Pyronemataceae) Jiri Moravec IHW Verlag. Softcover | 2005? You will see why a cotton blue mount of spores is necessary, as well as information on whether the spore sheath loosens when heated. And also though you show 2 hairs, you failed to photograph the base of the hairs, a very important feature. A difficult genus, requiring much work on your part.

Re:cheilymenia cf pulcherima ?
unfortunately, the photos of ascospores are not interpretable, I'm sorry.

All the best
