Summary
Description
Aglaothamnion priceanum is a small inconspicuous filamentous, deep pink coloured red seaweed, with a soft but not flaccid texture. Thalli consisting of small groups of erect axes, 0.2 - 0.8 cm high, attached by disk-like filamentous holdfasts or endophytic rhizoidal (root-like) filaments. Erect axes are flattened, with a single principal axis and a linear to irregularly fan-shape (flabellate) outline.
Recorded distribution in Britain and Ireland
Recorded from islands off northern and western coasts such as Shetland, Inverness and Argyll.Global distribution
This species is found in Norway and the Faeroes to Northwest France.Habitat
Confined to the sublittoral where it grows mostly on small perennial algae and blades of Laminaria hyperborea as an epiphyte, and also on bedrock at depths of 5-30 m. Tolerates moderate to extreme wave exposure.Depth range
-Identifying features
- Deep pink colour.
- Uninucleate vegetative cells.
- Zig-zag or U-shaped short side branches (carpogonial branches).
- Thalli consisting of small groups of erect axes attached by disk-like filamentous holdfasts.
Additional information
Identification of single specimens can be difficult, so if possible a number of thalli should be collected. However, the species is fairly easily distinguished using a microscope.Listed by
