Conferva floridula Dillwyn
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
This is a marine species.
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.
Turf-forming on sand-covered rocks, mid- and lower intertidal, often under Fucus serratus; widely distributed, very common.
Turf-forming habit and association with sand-coved rocks. Absence of monosporangia.
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.
