Conferva brodiei Dillwyn
Lectotype locality: Bantry Bay, (Co. Cork,) Ireland (Silva, Basson & Moe 1996: 537). Lectotype: Miss Ellen Hutchins; 24.vi.1807; BM-K (Maggs & Hommersand 1993: 314). Notes: This type locality was first recorded by Womersley (1979: 497).
Named for James Brodie, Scottish Naturalist; generally misspelled “brodiaei”.
Originally and generally misspelled as “brodiaei”; see Silva, Basson & Moe (1996: 537). Although Hollenberg (1944: 477) gave Scotland as the type locality, the figures (Dillwyn 1809, pl. 107) accompanying the original description are based on material collected by Miss Ellen Hutchins at Bantry Bay, Co. Cork, Ireland (see Womersley, 1979: 497). See Silva, Basson & Moe (1996) regarding orthography of the specific epithet (Guiry, 1997).
This is a marine species.
(as Polysiphonia brodiei (Dillwyn) Sprengel)
English: Brodie's Siphon Weed (Bunker & al. 2010).
Cartilaginous, cylindrical, tufted, dark purple-red fronds, to 300 mm long, from small conical basal disc. Branches irregular to pseudodichotomous, densely clothed with short, slender, much-divided branchlets, forming the distinct tufts characteristic of this species. Central siphon of main axes with 6-8 primary pericentral siphons and as many alternating secondary pericentral siphons, surrounded by small corticating cells. Branchlets ecorticate, with fewer pericentral siphons, articulations about as long as broad.
On rocks, stones, shells and corallines, mid-intertidal pools to subtidal, especially on exposed shores, generally distributed, common. According to Womersley (2003: 205), this species is usually found in or near harbour areas and may be spreading.
