on/under broken bark in loosening bark. Black with short- or long-beaked ostioles, smooth. Peridium strikingly red in water. Spores 2-celled, 13,6 x 5,1 µm, rather thick-walled, hyaline, apparently smooth. Asci 8-spored, apical appa. fairly prominent, refractive. Ascus base very long and thin.

Hi Thomas,

there is a key to these fungi in Reblova's paper, but I failed to find a genus matching well your fungus.

Mycologia, 105(2), 2013, pp. 462–475. DOI: 10.3852/12-199

Good luck!

Jacques

Thanks, Jacques.

I guess it keys out in Ceratolenta but with 2-celled spores, so could be a new or non-combined species in this genus? Even the red peridial colour fits well.

there is a more recent paper in SIM expanding the number of genera in this group of fungi. Torrentispora has thick-walled spores, check T. fibrosa with spores in the same size range, but there is no mention of the reddish peridium.

cheers,

Jacques

Re : sordarialean (± Lentomitella-like) in cracks on Fagus bark with red peridium, 2-celled spores
yes, Torrentispora is also close but the Danish collection has 2-celled spores, a non-aquatic habitat and possibly a less prominent apical apparatus and a thinner ascus stipe?
