Campylopus japonicus

A moss that forms loose, shiny tufts of upright stems 2–6 cm tall. The foliage is yellowish-green above and brownish below, with long narrow leaves (5–10 mm) that give each stem a feathery, star-like profile. Native to East Asia, Australia, and parts of Mexico, it does best in humid, shaded conditions on acidic substrates. In closed terrariums its upright habit and glossy sheen create a convincing miniature-forest look.
