Peziza s. l.
Marek Capoun, 01-08-2024 22:25
Marek CapounHello, I need help with this Peziza s.l. and at the same time I must confess I probably haven't done a good job.

It was found on probably calcareous mossy roadside soil under beech and oak, altitude 500 m.a.s.l.
1 apothecium only, 27 mm on average. I was thinking about P. saccardoana or P. depressa or some Legaliana, but the microcharacters don't match I think.
Excipulum composed of globose cells mixed with narrow and inflated hyphae, undifferentiated, but I may have made a mistake in not distinguishing the thin layer of text. intricata from the subhymenium. Latex not observed, but the apotecium was already somewhat drier. External thin pruinose layer of cells of text. prismatica.
Subhymenium – I don't know, how to described it, but look.
Asci cylindric, up to 260 µm, with amyloid reaction WT type, pleurorhynchous.
Ascospores from sporeprint in water 14.5–16.3 × 8.3–9.8 µm, Q = 1.6–1.9, N = 40, solely with 2 LBs, ornamentation from irregular warts, mostly up to 0,8 µm, rarely 1,1 µm in height, some somewhat pseudoapiculate.
Paraphyses straight, sometimes forked under the top, containing brown intracellular pigment.


It's possible, that some more of my confusions will follow in the next few days. I guess I'm 'lucky' now to only have the most uncertain or mysterious collections, but it's more likely I'm just having a period of some torpid asco-decline :-)
Many thanks for your patience ;-)
Marek

Re : Peziza s. l.
In my opinion, this collection belongs to the genus Paragalactinia, although you didn't observe any fluid in the flesh. Microphotos of the excipulum show a yellowish colour that could be a sign of the presence of this fluid, and there are also some elongated hyphae that might be laticiferous hyphae... The spore ornamention strongly reminds P. michelii.
The ecology is also compatible with this species.

Re : Peziza s. l.
Damn, you are absolutely right, of course.
Thank you.
