Hello forum,
another member of the Pezizaceae not clear to me is this collection. In the field and for a while under the microscope I thought it's P. varia, but the ascospores are still a bit large: 16.7–18.3 × 9.7–10.6 µm, Q = 1.64–1.8; N = 55 (the sporeprint in water). Smooth surface, no LBs, no BSG.
The layer of text. intricata is relatively thick, up to 190–250 µm. Asci around 280 × 17 µm in most cases, paraphyses slightly widened to club-shaped at apex, with several hyaline VBs.
Mainly it seems virtually not blueing in IKI, and if it is (and if it's not just a chromatic aberration), then only very slightly and not WTR type (pic. 12).
Growth on moist humus soil and debris in the bed of a seasonal stream under deciduous trees – oak, hornbeam, linden, altitude 350 m a. s. l. Only 2 apothecia, up to 18 mm on average.
Does anyone have a solution?
Thanks, Marek.
