Patches reddish-brown. Stems more than 1 inch long, 

 about one third of a line wide, lying nearly parallel, chan- 

 nelled above, annual prolongations narrowed at each end, so 

 the stem appears here and there strangulated. Leaves 

 closely imbricated even when wet, more patent than the 

 lobules, which are large and tumid. Perigonial leaves short, 

 obtuse, their lobules much inflated. No perichaetia or calyces 

 observed. The reddish colour, and the canaliculate and 

 strangulated stems are very distinctive of this species.
