Taxonomic notes
According to De Clerck et al. (2005: 177), Phyllymenia hieroglyphica J. Agardh, 1848 is a synonym of Grateloupia belangeri (Bory) De Clerck et al., 2005. - (23 Aug 2006) - Wendy Guiry

Schneider & Wynne (2013:115, 116) note that Gargiulo et al. (2013, in press) resurrected this genus from synonymy with Grateloupia using reproductive and molecular data. - (22 Jul 2013) - Wendy Guiry

Description: Foliose, lanceolate, cleft or uncleft, sometimes proliferous from margin, with short, narrow stipe and small discoid holdfast. Thallus surface corrugated. Medulla filamentous. Inner cortical cells stellate to elliptical, branching subdichotomously and becoming progressively smaller and fusiform toward cuticle, inner and intermediate cortical cells forming lateral protuberances. Rhizoids and secondary pit connections present. Ampullae with two orders of branches. Carpogonial branch 2-celled, on primary ampullar filament. Hypogynous cell with sterile lateral. Auxiliary cell a proximal cell of a primary filament or the basal cell of a secondary filament in a separate ampulla. A single, outwardly directed gonimoblast initial producing numerous gonimoblast filaments. Pericarp produced by ampullar filaments. Most gonimoblast cells maturing into carposporangia. Small auxiliary fusion cell and carpostome present. Cystocarp embedded. Spermatangia undescribed. Tetrasporophyte isomorphic. Tetrasporangia small, cruciate, attached subbasally in intermediate cortical layer.

Numbers of names and species: There are 8 species names in the database at present, of which 5 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
