Nomenclatural notes
Monotypic when first introduced. - (23 Jan 2017) - M.D. Guiry

Description: Plants form clusters of terete to pustular axes radiating from a basal stratum of filaments endophytic in the host. Thalli are small (to 5 mm diam.) and presumably wholly or partially parasitic. Gametophytes are monoecious, the spermatangia forming in sunken pits and the carpogonial branches located at the base of the cortex. Gonimoblasts develop outwardly and differentiate into catenate carpotetrasporangia, independent tetrasporophytes being unknown (Dixon and Irvine, 1977).

Information kindly contributed by G.T. Kraft but may now be outdated.

Comments: Distribution: Throughout the Arctic region of both hemispheres following the distribution of the host Phyllophora species. Also occurs southwards to the British Isles in the eastern Atlantic to Rhode Island in the west.

Numbers of names and species: There is only one species or infraspecific name 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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