Pyrenomycete on sandy soil
Gernot Friebes, 01-02-2011 07:42
Hi,

a friend of mine found this pyrenomycete on sandy soil between mosses. We do not have any idea because we have never seen such a species before and we aren‘t even sure if this is a „true“ pyrenomycete or a lichenized species (there were algae all over the substrate). Here is the description:

Ascomata black, slightly immersed, smooth, ± spherical, with a minute, round ostiole. Asci clavate, short stipitate, 8-spored, sometimes thickwalled (truly bitunicate?), when old somehow loosing the structure, maybe even dissolving, no apical apparatus seen. Paraphyses not observed, hymenium is quite gelatinous and ± sharply delimitate in a crush preparation, turning conspicuously reddish in IKI; ascomatal wall two-layered, outer layer dark brown, carbonized, inner layer of hyaline, roundish cells; spores hyaline to slightly brownish when overmature, mature with three septa but when overmature also with an additional longitudinal septum, constricted at septa, wall smooth, 27-35 x 11-12 µm.

Best wishes,

Gernot
