Holotype species: Lithophyllum expansum Philippi

Currently accepted name for the type species: Mesophyllum expansum (Philippi) Cabioch & M.L.Mendoza

Original publication and holotype designation: Heydrich, F. (1904). Stereophyllum, eine neues Genus der Corallinaceen. Beichte der Deutsche Botanischen Gesellschaft 22: 196-199.

Precise date of publication27 April 1904 (see Woelkerling & Lamy 1998: 681 for details). The requirements for valid publication are specified in the ICBN (International Code of Botanical Nomenclature).

Taxonomic status: currently regarded as a synonym of Mesophyllum.

Nomenclatural notes
The ICBN rules cited below are those adopted by the Seventeenth International Botanical Congress, Vienna, Austria, July 2005 (McNeill et al. 2006).

In accordance with ICBN Art 13.3, the name Stereophyllum is treated as pertaining to a non-fossil taxon because its type is based on a non-fossil specimen. No species based on fossil types have been assigned to the genus.

The generic name Stereophyllum is typified (ICBN Art. 10.1) by the type of S. expansum, the only species originally included in the genus.

Although validly published, Stereophyllum Heydrich (1904) is an illegitimate later homonym (ICBN Art. 53) of Stereophyllum Mitten (1859) (a genus of mosses) and of Stereophyllum Karsten (1889) (a genus of fungi). Thus, as noted by Woelkerling (1988: 193), the name Stereophyllum Heydrich, which is not conserved, must be rejected (ICBN Art. 53). - (20 Jul 2009) -

Taxonomic notes
According to Schneider & Wynne (2007: 203), this is a synonym of Lithophyllum Philippi. - (13 Oct 2010) - Wendy Guiry

Description: No description is currently provided as the name is illegitmate and is treated as a synonym.

Comments: Stereophyllum Heydrich was established for the single species S. expansum (Philippi) Heydrich. Woelkerling (1983: 307-313) concluded from an examination of the holotype that Lithophyllum expansum Philippi, the basionym, belonged to Mesophyllum,and based on circumstantial evidence, he treated it as a heterotypic synonym of M. lichenoides (Ellis) Lemoine. Subsequently, however, Cabioch & Mendoza (2003) concluded from an in-depth study of numerous collections that it represented a distinct species of Mesophyllum, and formally transferred it into that genus, as M. expansum (Philippi) Cabioch & Mendoza.

Numbers of names and species: There are 1 species names in the database at present.

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.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
