Overview

Gymnostomum viridulum is a species of moss in the family Pottiaceae. It has an almost cosmopolitan distribution.

Luisier's Tufa-moss is critically endangered due to its extremely restricted distribution to specific tufa-forming spring habitats that are highly vulnerable to hydrological changes and human disturbance. The species faces severe threats from water extraction, pollution, and habitat modification that can alter the delicate chemical conditions required for tufa formation and moss survival.
