衣魚 (Lepisma saccharina)
Will upload photos and ID later.
A big one!
Common polypody ferns are truly not rare in the European Alps, in this region it occurs together with Polypodium interjectum (hexa-ploid offspring) and occasionally with their hybrid P. × mantoniae.
Secure ID of those allied ferns is usually impossible without microscopic characters - possibly one reason for i often hesitated to take photos.
Those ferns do often grow on bark of old trees, rooting in humid mosses like here.
The area was recently devasted by logging so i could not take alike photos there now.
Juvenile (?female) found in sandy habitat off Kata Beach, Phuket, Thailand, holdfast leaves
