Apophlaea, 1845: 549
Holotype species: Apophlaea sinclairii J.D.Hooker & Harvey
Original publication and holotype designation:Hooker, J.D. & Harvey, W.H. (1845). Algae Novae Zelandiae; being a catalogue of all of the species of algae yet recorded as inhabiting the shores of New Zealand, with characters and brief descriptions of the new species discovered during the voyage of H.M. discovery ships "Erebus" and "Terror" and of others communicated to Sir W. Hooker by D. Sinclair, the Rev. Colenso, and M. Raoul. London Journal of Botany 4: 521-551.
Taxonomic status: currently recognized as a distinct genus.
Description: Thallus tough and leathery with a crustose base fully adherent to rock substratum. Rhizoids lacking. Horizontal filaments in crust giving rise to basal layer of downgrowing filaments composed of crowded isodiametric cells and to assurgent filaments of elongated cells separated by thick walls. Upper surface of crust and surfaces of erect axes covered by a thin cortex of isodiametric cells. Erect axes absent, unbranched, to dichotomizing several times. Branches terete, short and stout, or slender and to 15 cm. Elongated cells make up core of erect axes. Cells ca. 5 &m in diameter. Secondary pit connections common. Pit plugs with a cap membrane, but lacking an outer cap layer. Gametangia unknown. Tetrasporangia formed in pit-like conceptacles scattered over the surface of both erect and crustose portions of thallus. Tetrasporangia zonately divided, divisions parallel and transverse.
Comments: Hyphae of the fungus Mycosphaerella apophlaeae Kohlmeyer commonly present in walls and conceptacles, association possibly symbiotic. Two species known only from New Zealand and Subantarctic Islands. High intertidal.

Numbers of names and species: There are 3 species (and infraspecific) names in the database at present, of which 2 have been flagged as currently accepted taxonomically.
Names: ('C' indicates a name that is currently 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.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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