Mollisia cf caricina
Viktorie Halasu, 11-07-2024 14:29
Viktorie HalasuHello, 

a thin-fleshed Mollisia on a monocot stem (triangular, probably a Carex), on a grassland, in a narrow strip of taller herbs, reed and Rubus caesius along a rail track. Rather light colored excipulum with short clavate marginal cells. 
Paraphyses approx. *(2.9)3.8-4.4(5.8) um wide. Asci *25.2-27.2 × (3.7)4-4.5 um, H+, IKI+bb. 
No crystals. KOH negative. 
Spores *(4.5)4.7-5.8(6.1) × 0.9)1.1-1.3 um, X = 5.2 × 1.2 um, Q = 3.9-5.1. 

Mollisia caricina (the KOH- form on Typha) looks similar. What do you think?

Re : Mollisia cf caricina
Hello Viktorie!

I think that's a good name for now. This species may need a new name.
These KOH-negative "cf-caricinas" have so far only been found on Poaceae. The real Mollisia caricina probably grows on Cyperaceae and is KOH-positive.
But from your finding (KOH-negative + possibly Poaceae) you can see that there is still a lot of knowledge missing.

Greetings
Ingo

Re : Mollisia cf caricina
Hello Ingo, 
thank you for confirmation. Next time I'll try to have it sequenced too. It's from my favourite locality 15 min from home so there is a good chance to see it again.
