DESCRIPTION
Macromitrium orthostichum is close to M. pilosum with which it can easily be confused in sterile or immature conditions. Like this species, it is characterized by: 1) branches short, c. 5 mm long, funiculate, when dry, leaves erect appressed, incurved in upper part; 2) in wet conditions, branch leaves spreading squarrose recurved; 3) basal cells few, with many single papillae; 4) setae short, 2-4 mm long; and 5) peristome single. It can be separated from by: 1) vaginulae without conspicuous hairs; 2) setae verrucous; and 3) calyptrae shorter, covering half of the mature capsules, with many spreading hairs in basal part.
