Mollisia aff benesuada on leaf
Viktorie Halasu, 11-07-2024 10:57
Viktorie HalasuHello, 

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. 
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. 
Marginal cells short. 
Is there any name for this find?

Thank you in advance.

Hi Viktorie!

You can compare with Mollisia nervicola.

Greetings

Hi Ingo, 

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.

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.
