Overview
Bryoandersonia spp. is a moss genus in the family Brachytheciaceae represented by a single species, B. illecebra, the spoon-leaved or worm moss, native to eastern North America. It forms glossy, yellow-green to golden mats on soil, leaf litter, rotting logs, and shaded rock in deciduous woodland and along stream banks. The stems are smoothly cylindrical and worm-like (julaceous), 1 to 4 inches (2.5 to 10 cm) long, because the small concave leaves press closely and overlap around the stem rather than spreading. When dry the shoots curve and twist, and when moist they swell and glisten. As a moss, Bryoandersonia spp. has no roots, flowers, or water-conducting tissue; it anchors by hair-like rhizoids and takes up moisture over its whole surface. It reproduces by spores from curved, stalked capsules that ripen mainly in autumn and winter. The genus depends on shade and steady moisture, tolerating short dry spells by curling and reviving when rewetted.
Native Range
Bryoandersonia spp. is native to eastern North America, ranging widely through the eastern and central United States and into adjacent Canada. It grows in shaded, humid woodland on soil, rock, and decaying wood.Suggested Uses
Grown in shaded moss gardens, on logs and rocks in woodland settings, and in terrariums where humidity stays high. It forms a glossy, low carpet over damp ground and decaying wood. Its need for constant shade and moisture limits it to humid, sheltered spots.How to Identify
