Stems regularly 2-pinnate, smooth; paraphyllia 2--8 cells long, cells mostly 1:1, all papillose. Stem leaves appressed when dry, broadly triangular, (0.2--)0.25--0.32(--0.5) mm, gradually and broadly acuminate, sometimes piliferous; costa ending ca. 5/6 the leaf length. Secondary branch leaves incurved-appressed when dry, 0.15--0.25(--0.3) mm, acute to obtuse; costa ending ca. 3/4 the leaf length, straight, apical portions often covered with quadrate cells and thus projecting as low crests. Perichaetial leaves strongly flexuose-ciliate. Seta papillose throughout; endostomial cilia 1(--2).
