Conferva atropurpurea Mertens ex Roth

Type information
Type locality: Ad rotas molendinas Bremae in Visurgi primo ob. Julio 1801 Mertens, qui sub nomine Confervae castaneae comm. [Watermill on the Weser River, Bremen first observed in July 1801 by Mertens who communicated it under the name Conferva castanea] (Roth 1806: 208). Neotype: BM 000637980 (Müller et al. 2003: 216). Notes: Lectotype: Collected by Mertens from the Weser River at Bremen: lectotypified by Pfeiffer (1871-1873: 361) (Sutherland et al 2011). Neotype designated by Müller et al (2003: 216): Ysselmeer, Netherlands; coll. K. Müller & A. Sherwood, 24 May 1998; BM accession Number BM000637980. Roth's collection is believed to have been destroyed in World War II (Koster 1957 cited by Müller et al. 2003; Koster 1969 cited by Womersley 1994). [INA: England: Hampshire: near Southampton (Mr Woods); Wales: Camarthenshire: near Pontardylais. Collector: Mertens (vii 1801)].

Origin of species name
Adjective (Latin), black-purple (Stearn 1973).

Taxonomic notes
Based on molecular data, as well as chromosome number and morphology, Müller et al. (2003: 217) propose that B. atropurpurea should be re-recognized as a distinct species, separate from Bangia populations found in the marine environment. They suggest that marine populations should continue to be recognized as B. fuscopurpurea until their complex relationships can be resolved. - (18 May 2009) - Wendy Guiry

General environment
This is a freshwater species.

Common names

(as Bangia atropurpurea (Mertens ex Roth) C.Agardh)
Swedish: Purpurtråd (Tolstoy & Österlund 2003).

Gelatinous, unbranched, blackish-purple filaments, at first uniseriate later multiseriate, attached by rhizoidal outgrowths from basal and adjacent cells. Cells with central star-shaped chloroplast with pyrenoid.

On rock, wood, etc., as fleecy mat, especially at high tide level on exposed coasts in autumn and winter, disappearing in spring or early summer, at other times present as sparse filaments in shade at all levels and subtidally. Widely distributed, seasonally abundant.
