Mollisia cf rivularis

Hello, there's another Mollisia from the same stream, close to M. rivularis, but without LBs.
On water-soaked wood in a brook between spruce and beech forests, 620 m a.s.l. Apothecia cca 2 mm in diam., solitary or in groups.
Spores sometimes heteropolar, OCI=0.
Asci IKI+ bb, croziers+
Marginal cells short, brownish.
Medullary exc. = t. intricata, running mostly parallel to the surface, hyaline, no crystals.
Ectal exc. = t. angularis turned 90° to the surface, brown cell walls.
KOH negative
I couldn't get a good look on the paraphyses, I just assume that there are those long VBs.
Should I name it "cf rivularis", or is there a better name for this collection?
Thank you for any advice.
Viktorie

Re : Mollisia cf rivularis
I do not know well M. rivularis but the fungus by Joaquin seems to be similar.

Re : Mollisia cf rivularis
Andreas wrote somewhere here that rivularis should have OCI=1. Also Piotr Perz's collection in the database here has some small LBs. Also the spores of my collection are longer, there's only * 9-12(13) um in the key.
Andreas wrote here that there are some intermediate collections between rivularis and uda/pulviniformis, so I wasn't sure if this is not one of them too.

Re : Mollisia cf rivularis
In any case interesting. I fear with Mollisia one has to do molecular work together with detailed morphology.
