Mollisia associated with algae on wood?
Edvin Johannesen, 04-04-2025 11:56
Edvin JohannesenThese 0.2-0,4 mm diam. flat to slightly convex, greeninsh grey apothecia were apparently growing on a thick layer of algae on dead wood (Picea abies). The rim (ectal excipulum) is distinctly darker (greenish pallisade in water, warm yellow in KOH).

Asci ca. 50 x 5 µm, IKI+ (blue without KOH pre-treatment, ring-shaped).  Spores ca. 6-8 x 3 µm, biseriate in upper half of asci, ellipsoid or somewhat asymmetrical ("navicular"), mostly with no oil droplets or a few small ones at each end (in water).  Paraphyses rather robust, guttulate and appearing "septate".

I am thinking Mollisia, but I have no updated literature/key to the species of Mollisia. Your opinion is appreciated.  Thanks!

I suppose you have Durella suecica. I know it with dark and light colours.

That looks like a very good suggestion.  Thank you so much!
