Hello, a few days ago I have collected this Tarzetta.Disc 7-18 mm in diam., veil present, paraphyses without digitate tips, ascospores tapering toward the poles, (20.4) 21.2-22.2-23.1 (24.2) × (12.8) 13.4-13.8-14.3 (15.1) µm, Q = 1.52-1.60-1.72, n = 30.
Czech Republic, Moravia, calcareous background, ca 300 m a.s.l., on soil in a mixed forest - the closest trees were Populus tremula, Acer and Fraxinus.
Based on the morphology, the best candidates seem to be T. alnicola (but I haven´t noticed Alnus in the locality) or T. cupularis (Quercus surely grows in the locality, but not so close).
How would you identify it?
Zuzana
