Ombrophila-like (?) from the mine
Marek Capoun, 28-07-2021 22:14
Marek CapounHello everybody, I need help with the determination of this Ombrophila-like (?) asco.
Collected in a metal ore mine, where the temperature is constant around 8 degrees throughout the year, with very high humidity, the entrance to the mine at altitude cca 620 meters.
It grows on a supporting strut from a trunk of Abies (very probably - the local attendant said).
Ascomata max. 4 mm on average, stalked, in youth whitish, later turn red during the maturation or drying.
Microscopy with the partially dried material unfortunately. Ectal excipulum with vertical textura prismatica, medulla gelatinous. A lot of crystals up to 12 µm large sometimes.
Asci with croziers, 80-120 µm long, IKI with blue reaction on the lower part of the ring. Paraphyses cylindrical, sometimes wider slightly or curved at the top, with large VBs.
Ascospores hyaline, one–celled, elliptical or narrowly ovoid, Me = 7.5 × 4 µm, Qe = 1.9; with 2 LBs.
Thanks for your help.
Marek

Re : Ombrophila-like (?) from the mine
This is an Ombrophila for sure, and perhaps O. violacea, the type species of the genus. Good would be to give the range of spore size. I estimate 7-8.5 x 3.8-4.2. Literature data say 6-11 x 3-4 for this species. The apical ring is perfect for this species.

Re : Ombrophila-like (?) from the mine
Your guess is accurate, hats off :-)
6.8-8.3 × 3.7-4.2.
Thanks.
