Re : Interesting orange asco on grimmia
Interesting! Any obs. on the excipulum? The amyloid ring looks a bit like everted, do you have more photos, especially of younger asci?

Re : Interesting orange asco on grimmia
I see a large apothecium and a very small immature one. Surely this is helotialean.

Re : Interesting orange asco on grimmia
Yes it is apothecia, 

I did add pictures of asci in K/I
Young asci in water
Spore in K 
Excipulum in water

I did also note that some parafyses is branched, apothecia is K -
and i also measuerd longer 3 sept spores reach up to 24 um in this cut.

Re : Interesting orange asco on grimmia
Now it is clearly Calycina-Type. After this I wonder about the croziers. A relationship with "Bryoscyphus" could be possible but then I would expect crystals in the medulla.

Re : Interesting orange asco on grimmia
Dear zotto,

Take it as unfavourable coincidence or as incompetence, but i cant comfirm if it has croziers or not. have have made severel cuts and dont se it, its mostly a goo and when trying to seperate it gently it mashed.

but its no crystals that i can see.

ad spores in Crb.
