Membranoptera alata (Hudson) Stackhouse
Description: Membranous, deep crimson to
brownish red fronds, to 200 mm long. With short stipe,
well-marked midrib (above), and narrow, winglike monostromatic
margins, pinnately veined, to 12 mm wide (margins often lacking
in older plants). Branching irregularly dichotomous, frequently
proliferating from midribs, apices blunt.
Habitat: On rocks or onstipes, lower intertidal
and subtidal, generally distributed, common.
Similar species: Pantoneura angustissima (Turner) Kylin is reported
epiphytic on Laminaria hyperborea stipes from the
subtidal of NE Scotland in winter. This entity is much confused
with narrow forms of Membranoptera alata, which become
increasingly common as one progresses northwards. No authentic
records of Pantoneura from Britain are known since the
19th century.
