The moss Bryum bornholmense, was found in two samples collected in “Paul da Praia da Vitória” in February 2016. The species is characterized by its leaves – with a thick costa at the base (65-100 μm), ending in leaf apex, and a distinct border of 1–2(4) rows of narrower cells. The rhizoidal tubers are also quite characteristic: large (200–350(450) μm, brownish yellow to brownish orange, with thin-walled cells, not to slightly protuberant, (30)45–60 μm (see images above).
