Mollisia on Poaceae
Juuso Äikäs, 08-07-2021 20:51
I found this Mollisia species yesterday, growing on dead grass stems on the bottom of a mostly dried-out ditch.

KOH+ yellow, pp rather wide and with VBs, croziers+. Spores: 7.4 - 10.1 × 1.4 - 1.8 µm.

Tho spores are pretty long, but otherwise could this maybe be Mollisia caricina?

Re : Mollisia on Poaceae
M. caricina is impossible , at least in my concept where the spores are much smaller and the paraphyses wider.

Ok, thanks. I'll keep it just Mollisia sp.

Hallo,

this could be Mollisia citrinopigmentosa Svrcek may be, but I have not seen the type and no real idea of this species. The spores are said to contain no oil drops, but theses data are from dead spores and have to be taken with care.

all the best,Andreas

Re : Mollisia on Poaceae
Good idea, Andreas, I only cannot estimate the "wax-yellow" colour of the disc in the type, which seems to be present already without alcali. But Svrcek wrote that ammonia caused a yellow reaction.

Re : Mollisia on Poaceae
I checked the dried sample today in KOH and the spores do seem to still have drops. And ammonia fumes turned the apos yellow (maybe in other KOH+ yellow Mollisias as well, I'd assume).

Re : Mollisia on Poaceae
Yes, ammonia and KOH do quite the same in Mollisia as far as I see.

Re : Mollisia on Poaceae
Hello,

as Zotto said, Ammonia and KOH do the same in Mollisia. I tested that several times. Also KOH 3% and KOH 10% and KOH 20% do the same results to my experience.

the spores from your specimen seem to be still alive, at least they look like. May be the drops are more difficult to observe or even absent when the specimen is some years old.

I have not checked the type, as said, on so am not sure wether they have drops or not. But Svrcek states that they don't have ....

all the best, Andreas
