Original publication:Reinsch, P.F. (1875 '1874/75'). Contributiones ad algologiam et fungologiam. Vol. 1 pp. [i]-xii, -103, [104, err.], 131 plates [I-III, IIIa, IV-VI, VIa, VII-XII, XIIa, XIII-XX, XXa, XXI-XXXV, XXXVa, XXXVI (Melanophyceae); I-XLII, XLIIa, XLIII-XLVII, XLVIIa, XLVIII-LXI (Rhodophyceae); I-XVIII (Chlorophyllophyceae); I-IX (Fungi)]. Norimbergae [Nürnberg]: Typis Theodor Haesslein.
Taxonomic status: uncertain, requiring further investigation.
Papenfuss (1964: 32) notes: "Plectoderma was erected by Reinsch (1875, p. 52) on the basis of two species, P. minus and P. majus. De Toni (1905, p. 1764) has placed the genus in the synonymy of Melobesia Lamouroux, and to judge from Reinsch's illustrations of the two species it would seem that both are representative of encrusting corallines - Melobesia of Fosliella. The South Georgia plant referred to P. minus by Reinsch is not representative of this species, but what it may be cannot be determined from this description and illustrations." - (16 Sep 2008) - Wendy Guiry
Numbers of names and species: There are 2 species names in the database at present, of which 2 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..
Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.
