Corallium lichenoides J.Ellis

Type Information
Type locality: Not stated in protologue (Ellis 1768) but Ellis (1755) and Ellis & Solander (1786) cite Cornwall, England as the source material; (Woelkerling & Irvine 1986: 392) Epitype: BM; algal box collection 1658 (Woelkerling & Irvine 2007: 230) Notes: Woelkerling and Irvine (2007) note that the neotype (collected at Hannafore Point, West Looe, Conwall) of Woelkerling and Irvine (1986b) has to be superseded because ICBN rules governing the selection of types have changed. The 1768 illustration designated as lectotype does not provide sufficient anatomical or reproductive information to allow unequivocal identification at genus or species levels. Therefore, the unacceptable neotype of Mesophyllum lichenoides(J. Ellis) Me. Lemoine (BM: Algal Box Collection 1658, barcode 000568779BM) is designated as epitype.

Origin of Species Name
Adjective (Latin), like a lichen.

General Environment
This is a marine species.

Pale to dark purple thin, brittle, leafy calcified fronds, attached at base, margins free, lobed. Fronds semicircular, concentrically banded. Reproduction takes place in winter and spring in small, wart-like conceptacles.

Epiphytic on Corallina officinalis in tidal pools; southern and western shores to Orkney Islands, occasional, locally frequent. Further south in the Atlantic, plants of this species occur on rock, but it the British Isles, the species is always epiphytic.
