Reports for the Azores:

non Ophiomitrella clavigera (Ljungman, 1864) — Mortensen 1927a: 186–187, fig. 103 [based on invalid synonymy]; Marques 1980: 102 [based on Mortensen 1927a]; Paterson 1985: 71, fig. 28 [based on Mortensen 1927a]; Harvey et al. 1988: 170 [based on Paterson 1985]; García-Diez et al. 2005: 49 [based on Mortensen 1927a].

See: Mortensen (1933a: 39–41, fig. 23); Paterson (1985).

Occurrence: North Atlantic, in the west from the Northern American coasts to Greenland and in the east from Iceland and Scandinavia to the British waters (Mortensen 1933a, Paterson 1985).
