Origin of Species Name
Adjective (Latin), purple (Stearn 1973).
This is a marine species.
Plants forming matted purplish-red tufts or a thin turf of sparingly branched, erect filaments, 5-10 mm long. Cells 3-4 times as long as broad. Cells with a single reticulate plastid without pyrenoids, later fragmented. Reproducing by tetrasporangia, mostly in winter. Monosporangia absent.
On rock or epiphytic (especially on Laminaria hyperborea stipes), upper infralittoral to subtidal, often in caves and shady crevices. Widely distributed, common.
Turf-forming habit and association with upper intertidal, shaded habitats or Laminaria hyperborea stipes. Absence of monosporangia.
Rhodothamniella floridula, which forms more extensive turfs. Microscopic examination (for the presence or absence of pyrenoids) is required to be certain of the identity of this species.
