Summary

Description

Membranoptera alata is a red or reddish-brown seaweed, up to 20 cm in length, with a flat, narrow frond. It exhibits a midrib and many fine, lateral veins, which can be clearly seen under a hand lens. It has many branches, arising from the central axis, which are irregular, dichotomous, and copiously branched in one plane. This perennial plant has a thin membranous thallus.

Recorded distribution in Britain and Ireland

Widely distributed throughout the British Isles but not recorded from parts of eastern England.

Global distribution

Common and widely distributed in north west Europe.

Habitat

Grows on rocks or on other red and brown seaweeds as an epiphyte, particularly laminarians. Inhabits shady rock pools, the sublittoral and deeper waters.

Identifying features

  • Blades width 0.6-2.4 mm.
  • Conspicuous midrib width of 0.15-0.5 mm, with many lateral veins.
  • Branches are irregular, dichotomous, and copiously branched in one plane.

Additional information

Membranoptera alata can sometimes be confused with Hypoglossum woodwardii. However, Hypoglossum woodwardii lacks the distinct lateral veins found in Membranoptera alata. Membranoptera alata is fertile in the winter months.
