Mollisia aff benesuada on leaf
Viktorie Halasu,

I have here a Mollisia on a leaf (possibly Quercus rubra) laying on a grassland. Alas, no macrophoto. M. benesuada seems close, but it had a fleeting KOH+ reaction.Â
Spores *(6.7)7.4-9.1(9.7) × (1.6)1.8-2.1(2.2) um, X = 8.3 × 1.9 um, Q = 3.8-4.4-4.9.Â
Marginal cells short.Â
Is there any name for this find?
Thank you in advance.

Hi Viktorie!
You can compare with Mollisia nervicola.

Re : Mollisia aff benesuada on leaf
Hi Ingo,Â
thank you, your collections of M. nervicola are indeed very similar to mine. I originally excluded this hypothesis, because Zotto's folder also includes colls. with much darker apothecia ("cf" on your website) having brown excipulum cells up to the margin + longer, sometimes also dark, marginal cells. Does it grow only on Quercus leaves? My coll. was on rather strangely developed leaf, assymetrical, short, but it seemed like a Quercus. Perhaps actually Q. robur, I remember it had only short petiole.Â

Re : Mollisia aff benesuada on leaf
I see that so far Quercus spp. and Castanea are the only hosts so far. The species seems variable and I am still unsure if muelleri-argviensis with 1-septate spores is the same.
