Andreaea rothii, or Roth's andreaea moss, [3] is a species of moss in the family Andreaeaceae native to North America and parts of Europe. [4] [5] This plant was described in 1807 by Weber and Mohr. [5]

Description

Andreaea rothii gametophytes sometimes form extensive black to brown cushion-like patches, [6] [5] with individual shoots erect and less than 2 cm tall. [6] The leaves of Andreaea rothii are 1-2 cm wide, and have a strong costa, [6] [7] which is roughly synonymous to a midrib. The leaves can be falcate-secund, curving to one side of the plant. [6] [5] [7] This is especially true when wet, however the plants do not alter much when dry. [6] The outline of the leaf is pear-shaped, swelling at the base and tapering to a tip, [6] [5] and can also be strongly curved depending on subspecies. [6]

Distribution

Andreaea rothii grows on rocks that are wet, acidic, and exposed. [5] [6] This species is found anywhere from areas of high elevation to sea-level. [6] [5]

Reproduction

Andreae rothii gametophytes can be gonioautoicousmeaning the antheridia are bud-like in the axil of an archegonial branchor cladautoicousmeaning the antheridia and archegonia are found on different branches of the same plant. [7] Like all of the Andreaeaceae, sporangia are elevated on a pseudopodium, [8] a structure resembling a seta but composed of gametophyte tissue rather than sporophyte tissue. The sporangia will dehisce longitudinally, forming slits through which spores are dispersed. [8] [9] This pattern of dehiscence gives the genus its common name: "Lantern mosses".
