Taxonomic status: currently recognized as a distinct genus.
Most recent taxonomic treatment adopted: Silberfeld, T., Rousseau, F. & Reviers, B. de (2014). An updated classification of brown algae (Ochrophyta, Phaeophyceae). Cryptogamie Algologie 35(2): 117-156.
Description: Plants forming small (about 1 cm tall), dense, dark reddish brown, subglobose tufts on larger Phaeophyceae (Sporochnales); heterotrichous. Basal parts with intricate, irregular filaments forming irregular, multicellular, endophytic structures in the host. Erect filaments terete, articulate, isodiametric, bushy, unbranched or with few to many divaricate, irregularly placed, unbranched laterals. Segments cut off from the short or elongate cylindrical apical cell of the erect filaments transversely dividing once or not after separation. No longitudinal segmentation observed in these segments. Hairs or rhizoids not observed. Chloroplasts without pyrenoids, parietal, small and lenticular, several in each cell. Reproductive structures: Only ovoid unilocular zoidangia observed. Mediterranean coasts of Spain and Italy, Canary Islands, South Australia, probably confined to the deeper sublittoral. In Europe endophytic in Carpomitra costata and Sporochnus pedicellatus; in Australia endophytic in Bellotia eriphorum. The life history is incompletely known.

Numbers of names and species: There are 2 species names in the database at present, of which 1 has 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
