Black Mollisia 240325 on Tamarix

Miguel Ángel Ribes, 26-03-2025 20:51

Good afternoon

This pretty black Mollisia was growing on wet Tamarix wood, in fact at the magnifying glass I did not think at any time that it was a Mollisia. They are small cups of 1.5 2 mm in diameter.

The ectal excipulum has textura subglobulosa, becoming more prismatic towards the margin, where the terminal cells are cylindrical-claviform and very dark brown. The medullary excipulum has textura intricata. The asci are cylindrical, octosporic, biseriate, with croziers and IKI-. Paraphyses are cylindrical with a large VB occupying the entire terminal cell, with negative reaction to KOH. Ascospores are cylindrical-allantoid, without LBs, (6) 7 - 8 (8.3) × (1.6) 1.9 - 2.2 (2.4) µm; Q = (2.8) 3.3 - 4.1 (5); N = 56; Me = 7.4 × 2.1 µm ; Qe = 3.7,

With the keys I can't come up with anything coherent.

Thanks for your help.
