Forming deep green, dense tufts or mats. Individual plants are one-half to a couple of inches tall. Leaves are about a millimeter long, spreading, oblong, and pointed. A central midrib (called a costa in mosses) gives them reinforcement. When dry, the leaves become wavy and press up against the stem; however, they are rarely, if ever dry in the Park. Spore-bearing capsules form in the autumn.

A moss of limestone tufa, limestone seeps, and moist or wet limey rocks and soils along streams and rivers and by waterfalls. In Wildwood it is one of the dominant species on the tufa of the weeping cliffs at the Main Street entrance (top left). It is native from northern Greenland to southern South America and also in Europe, Asia, Africa and New Zealand.

I would nominate this as the official moss of Wildwood Park, given its preference for growing on our iconic weeping tufa. Other mosses also grow in this watery habitat, including Tangled Thread Moss (Hygroamblystegium varium).
