Habitat

Saxicolous on water saturated calcareous and ultramafic rocks, in pools of water or on water saturated soil.

Features

Erect or ascending yellowish moss of water saturated ground or growing within springs or on wet calcareous boulders and/or ultramafic substrates. Stems to 30 mm long, radiculose below, paraphyllia scant, rather regularly but not complanately pinnate, with short (up to 7 mm long) slender, flexuose branches. Leaves spreading to suberect, little altered when dry. Stem-leaves c.1 mm long; lamina ovate-cordate from a narrow decurrent base, gradually and finely acuminate; margins plane, rather finely denticulate; nerve of variably length but often contained well into acumen or nearly to apex; branch-leaves similar but smaller, ovate-lanceolate, acuminate. Cells 20-28 microns long and 3-5 x 1, smooth, elliptic-hexagonal to linear-rectangular; wider and subrectangular towards the basal angles, there sometimes enlarged and thin-walled, so as to form clearly decurrent auricles. Fruits not seen.
