Andreaea rothii, or Roth's andreaea moss, is a species of moss in the family Andreaeaceae native to North America and parts of Europe. This plant was described in 1807 by Weber and Mohr. It is found on rocks that are wet, acidic, and exposed anywhere from areas of high elevation to sea-level. Andreaea rothii forms sometimes extensive black to brown cushion-like patches, with individual shoots erect and less than 2 cm tall. The leaves of Andreaea rothii are 1-2 cm wide, and have a strong costa. They can be falcate-secund, especially when wet, however the leaves do not alter much when dry. The outline of the leaf is pear-shaped, swelling at the base and tapering to a tip, and can also be strongly curved depending on subspecies. Like all of the Andreaeaceae, sporangia are elevated on a pseudopodium, and will dehisce longitudinally, forming slits through which spores are dispersed.
