Mollisia on grasses
Enrique Rubio, 25-07-2012 19:43
Enrique RubioThis Mollisia species grews at the very humid  basal parts of grasses (maybe Molinia caerulea) in peat bog soil at 800 m of altitude.
The ascomata, up to 1 mm, grew on a + or- developed brownish subiculum and the hymenium is yellowish or amber. KOH is clearly yellowish (+) but not strongly yellow. Ascospores are eguttulate. Asci IKI b, up to 75 x 8, 8-spored, with croziers. Paraphyses have cylindrical Vb's or fragmenting refractive Vb's,
Medullary excipulum with hyaline or subhyaline textura intricata. Ectal excipulum with vesiculose or angular hyaline or palid yellowish cells. Marginal cells are clavate, hyaline and slightly gelified.

I think in Mollisia citrinopigmentosa but 'my spores' are bigger
What do you think?

Re : Mollisia on grasses
Dear Enrique

this is dificult. Your species does not have too much characters, apart from a hyaline excipulum. I nocnur with the genus Mollisia, but more I can hardly say.

I read the diagnosis of Tapesia citrinopigmentosa Svrcek 1993. His illustration does not help much, and he studied the material from the dry state, so we have no info on paraphysis contents. The excipulum is said to be brownish, and the apothecial exterior brown. I hope he did not describe Rodwayella citrinula...

I do not know why the species is in Andreas' key under M. hydrophila, as it is  not said to have crystals in the medulla.
