Status of name
This name is of an entity that is currently accepted taxonomically.
Fucus elminthoides Velley
Type locality: "Grows in abundance upon the rocks off the Beal, at the extremity of Portland [Dorset, England], at very low water. June. July. ... Major Velley." (Withering 1792: 255). Lectotype: LIV (Womersley 1994: 81). Notes: Batters (1902: 59) "e spec. auth. in Herb. Kew.", which could be considered a lectotypification so that the lectotype would be a specimen in BM-K.

According to Athanasiadis (2016: 142): "Originally spelled elminthoides, ... but as the first letter is aspirated it has to be written helminthoides - h standing for the spiritus asper. However, Art. 60.3, clearly says "The liberty of correcting a name is to be used with reserve, especially if the change affects the first syllable and, above all, the first letter of the name." - (1 Feb 2017) - M.D. Guiry
In making the combination Chaetophora rubra, based on Ulva rubra Hudson, C. Agardh (1812) cites Rivularia multifida Weber & Mohr 1804 as a synonym which led authors to regard this entity as a Nemalion. If it does indeed represent this entity, Ulva rubra may be an early name for a species of Nemalion; however, Hudson's material from the south coast of England has not been re-examined. - (24 Jun 2014) - M.D. Guiry
This is a marine species.
Japanese: Umisomen, Tsukomo Nori (Madlener 1977).
Cylindrical, reddish to purple brown, softly gelatinous thallus, simple or sparingly dichotomously branched, to 2 mm wide, to 250 mm long, with discoid base.
World-wide on temperate coasts during summer (Womersley 1994: 81). Summer annual (May or June-September or October) on exposed rocky shores, generally growing on barnacles and limpets in the lower intertidal, locally common on southern and western shores, rare and local on east coasts.
Helminthocladia calvadosii (Lamouroux ex Duby) Setchell is a relatively rare subtidal species found on western and southern shores of Ireland and Britain. It is generally larger and broader than Nemalion and more profusely and irregularly branched. Helminthora divaricata is more profusely branched and is an epiphyte of Polyides rotundus.
