Endophyton N.L.Gardner, 1909
Holotype species: Endophyton ramosum N.L.Gardner
Original publication and holotype designation: Gardner, N.L. (1909). New Chlorophyceae from California. University of California Publications in Botany 3: 371-375.
Taxonomic status: currently recognized as a distinct genus.
Description: Endophyte of sparingly and irregularly branched filaments within host medulla, producing short branches toward its surface. Vegetative cells with parietal more or less perforated chloroplast with one to few pyrenoids. Cells of 'medullary filaments' relatively thin, long, and pale whereas those in host cortex relatively broad, short, and green. Hairs not formed. Apical cells of branches in host cortex form sporangia; biflagellate anisogametes or quadriflagellate zoospores produced after sequential division of protoplast. Germination unilateral. Generations isomorphic. Haploid chromosome number = (9)-10-(11) for E. ramosum. Endophyton endophytic in red and brown algae, recorded from Pacific coast of North America, Bering and Antarctic Seas. Although only one species known, a second name is a nom. nud. Eight different morphotypes breafly mentioned in literature which may represent different species.

Numbers of names and species: There are 3 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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