Funaria hygrometrica

About

Funaria hygrometrica, the bonfire moss or common cord-moss, is a type of water moss which grows on shady, moist soil. It can also be found on moist walls and the crevices of rocks and places where recent fires have taken place. It has been reported to grow in Niagara Cave, an artificially illuminated cave devoid of natural light. Under such conditions, its growth form changes so that the internodes lengthen and the leaves become longer and narrower.
