on a fallen tree in pond
I've taken some more pics here:
https://www.inaturalist.org/observations/163362594

on top of gabion filled with stones on bottom of periodic stream

on the ground

on a bank of small pond

IMO the amfigastrium are separated, not overlapping (as in P. platyphylla).

the observation was edited according to suggestions below

inside a long cave, in front of a lamp

on pine tree

on dry meadow, moss abundant

On a stone wall / na murze kamiennym

on a stream bank (vertical slope), mixed forest

fir forest

on concrete

picture 3 shows all I've found about amfigastrium - seems to be deeply cut. According to my key, it means C. muelleriana or C. sphanicola. But was found on sandy ground away from peatbog.

on a dry slope over forest road

found by PZ

on branch

On rotting tree, possibly oak, in predominantly birch wood. The biggest patch I've seen.

I took a sample, it was very tightly joint with the ground. I failed finding the amphigastrium, only a very tiny object took my attention, see the last picture.

On sandy, open site

on a fallen branch

• milieu acide, bord de mare, platière
• absence de gemmes
• pas d'amphigastre visible
