Ceramiales COI-5P DNA barcode phylogeny rbcL Rhodophyta systematics taxonomy
The poorly known Western Australian species of the red algal genera Callithamnion Lyngb. and Corynospora J.Agardh (Ceramiales) described by William Henry Harvey in his seminal 1855 paper are reassessed based on morphological and molecular analyses of original and recent collections. Several generic reassignments are proposed, including Desikacharyella australis (Harv.) Huisman, Verbr. & G.W.Saunders (for Corynospora australis Harv.), Guiryella gracilis (Harv.) Huisman, Verbr. & G.W.Saunders (for Corynospora gracilis Harv.), Anotrichium flabelligerum (Harv.) Huisman, Verbr. & G.W.Saunders (for Callithamnion flabelligerum Harv.), Pleonosporium perpusillum (P.C.Silva) Huisman, Verbr. & G.W.Saunders and Pleonosporium crispulum (Harv.) Huisman, Verbr. & G.W.Saunders (for Callithamnion perpusillum P.C.Silva and Callithamnion crispulum Harv.), Aglaothamnion scopula (Harv.) Huisman, Verbr. & G.W.Saunders (for Callithamnion scopula Harv.) and the elevation of Anotrichium thyrsigerum (Harv.) Huisman, Verbr. & G.W.Saunders (for Callithamnion thyrsigerum Harv., previously treated as a variety or synonym of Anotrichium tenue (C.Agardh) Nägeli) to species level. In addition, Callithamnion cliftonii Huisman, Verbr. & G.W.Saunders is proposed as a replacement name for the illegitimate Callithamnion multifidum Harv. and this, and Callithamnion debile Harv., are retained in the genus. Two new species, Ptilothamnion harveyanum Huisman, Verbr. & G.W.Saunders and Seirospora decipiens Huisman, Verbr. & G.W.Saunders, are described from recent collections.
