Robin Isaksson, 30-12-2024 23:57
Robin IsakssonHi! This one i have hard to find anything on.
Does anyone know it? Macropicture 0.5mm / micro 10um.
Spores first aseptate, later 3-septate.
16-19 x 4-4.5 um, smooth, young with many droppets, older with bigger and few.
Asci 8 spores, 77-89 x 10-11, iki + blue.
Apothecia orange, 0,31 - 0,51 mm.

I can take more pictures if needed.

Best regards

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.
