Publication details
Rhodothamniella floridula (Dillwyn) Feldmann in T.Christensen 1978: 67

Published in: Christensen, T. (1978). Annotations to a textbook of phycology. Botanisk Tidsskrift 73: 65-70.

Type species
This is the type species (holotype) of the genus Rhodothamniella.

Status of name
This name is of an entity that is currently accepted taxonomically.

Basionym
Conferva floridula Dillwyn

Type information
Syntype localities: "Rocks on the Sea shore. On the Galway Coast; Dr. Scott. On the Antrim Coast; Mr. Mackay." [Ireland] (Dillwyn 1809: 73). Lectotype: BM (Woelkerling & Womersley 1994: 45). Notes: Type locality: Galway coast, Ireland; Holotype (cited as lectotype in Diaz-Tapia, 2014): NMW (fide Woelkerling, 1971: 31). "Dr Scott" was probably Robert Scott (ca 1757-1808), Professor of Botany at Trinity College Dublin from 1800 to 1808. Mr MacKay was James Townsend MacKay (ca 1775-1862), first curator of the [Trinity] College Botanic Gardens, then at Ballsbridge, Dublin, from 1808, and an Assistant at TCD from 1806. [Woelkerling 1971: 31 cites NMW but later publications cite BM (Dixon & Irvine, 1977: 97; Woelkerling & Womersley in Womersley, 1994: 45)].

Origin of species name
(Latin), a diminutive of floridus meaning, somewhat blooming.

Habitat notes
Sand-covered rocks; from the upper intertidal to the upper subtidal, in sites from shelterd to extremely wave-exposed ( Diaz-Tapia & Bárbara, 2014) - (24 Jun 2014) - Wendy Guiry

General environment
This is a marine species.

Common names

(as Rhodothamniella floridula (Dillwyn) Feldmann)
English: Sand Binder (Bunker et al. 2010).

Description
Forming a dense, brown- or purplish-red turf of sparingly branched erect, uniseriate hair-like filaments. Cells oblong, 3-4 times as long as broad. Several plastids, each with a pyrenoid, against cell wall. Reproducing by tetrasporangia, mostly in winter. Monosporangia absent.

Habitat
Turf-forming on sand-covered rocks, mid- and lower intertidal, often under Fucus serratus; widely distributed, very common.

Key characteristics
Turf-forming habit and association with sand-coved rocks. Absence of monosporangia.

Similar species
Rhodochorton purpureum forms less extensive turfs. Microscopic examination (for the presence of pyrenoids in plastids) is required to be certain of the identity of this species.
