Schmidt, W. E., Gurgel, C. F. D. & Fredericq, S., 2016, Taxonomic Transfer of the Red Algal Genus Gloiosaccion to Chrysymenia (Rhodymeniaceae, Rhodymeniales), Including the Description of a New Species, Chrysymenia pseudoventricosa, for the Gulf of Mexico, Phytotaxa 243 (1), pp. 54-70 : 65

Chrysymenia coriacea (Harvey) W. E. Schmidt, Gurgel & Fredericq , comb. et stat. nov.

BASIONYM: Gloiosaccion brownii Harvey var. coriaceum Harvey 1859a , pl. 83

SYNONYM: Gloiosaccion brownii Harvey var. coriacea Harvey 1859b, p. 322

Gloiosaccion brownii Harvey var. β firmum Harvey 1859a , pl. 83

Halosaccion firmum sensu Harvey 1855, p. 556 (non Postels & Ruprecht 1840: 19, pl. 35B)

TYPE: Georgetown, Tasmania, Australia (Harvey, Alg. Aust. Exsiccata no. 420)

NOTE: Since Chrysymenia firma J. Agardh 1842 is the basionym for Lomentaria firma (J. Ag.) Falkenberg 1879 , the ‘ firma ’ varietal epithet is rejected as it applies to the taxon Gloiosaccion brownii var. firmum (see ICBN, Saint Louis Code, Ch. 5, article 53). Womersley (1996) noted that Harvey (1859a, pl. 83) described two varieties, α membranaceum and β firmum , that probably correspond to young and older plants and were not worth recognizing, and that he ( Harvey 1859b, p. 322) apparently changed firmum to coriaceum , referring to exciccatum no. 420. The variety ‘ coriaceum ’ ( Gloiosaccion brownii Harvey var. coriaceum ), viewed as a superfluous or illegitimate name of variety ‘ firmum ’ ( Silva et al. 1996) is here viewed as a legitimate substitute name for G. brownii var. firmum and is elevated to species level with a new combination and new status. The taxonomic status of G. brownii Harvey var. furcatum Harvey 1863 : xliv (syntype localities western Australia and Georgetown, Tasmania) has not been clarified in this study.
