Little black Peziza (apiculate)
Zuzana Sochorová (Egertová), 27-08-2024 17:12
Zuzana Sochorová (Egertová)Hello,
I would like to consult this little Peziza, which macroscopically resembles Plicariella scabrosa (especially when young).

There were 3 apothecia, 3.5-8.5 mm in diam., black, with a rough outer surface.

Ascospores (17) 18.6-21.2 (22.9) × (10.1) 10.3-11.6 (12.6) µm, Q = (1.6) 1.7-2; n = 32, Me = 19.8 × 10.8 µm; Qe = 1.8 (without orn.), ellipsoid to subfusoid, uninucleate. Ornamentation very variable, consisting of warts which partly anastomose; the poles are sometimes multiapiculate, spiny, or with ornamentation resembling a fish fin, while sometimes the warts are not higher than elsewhere on the spore surface. The height of polar ornamentation is mostly 0.5-1.5 µm, rarely up to 2.7 µm. I have never observed a spore with a single large apiculus, typical for Peziza apiculata. 

Czech Republic - Moravia, 25 August 2024, on soil near a brook, on calcareous background (together with Melastiza flavorubens).

The best option I have found is Phaeopezia vagneri, but the spore size given in literature is somewhat larger. What do you think?

Re : Little black Peziza (apiculate)
I think Phaeopezia vagneri is the best hypothesis.

Great, thank you very much for confirmation!
