Holotype species: Pilinia rimosa Kützing
Original publication and holotype designation: Kützing, F.T. (1843). Phycologia generalis oder Anatomie, Physiologie und Systemkunde der Tange. Mit 80 farbig gedruckten Tafeln, gezeichnet und gravirt vom Verfasser. pp. [part 1]: [i]-xxxii, -142, [part 2:] 143-458, 1, err.], pls 1-80. Leipzig: F.A. Brockhaus.
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: Branched, uniseriate, mat-forming filaments lacking modification of cells for attachment and lacking differentiation between prostrate and erect portions. Cells very small, 6-8.5 µm broad and up to twice as long, containing one or 2 parietal, lobed, plate-like chloroplasts with a pyrenoid. Reproduction by unilocular sporangia (mistaken in previous literature for plurilocular structures) as confirmed by electron microscopy (unpublished obs.), producing only 4 biflagellate zoospores, each with a chloroplast and eyespot. Zoospores germinating in culture to produce repeated generations of unilocular sporangia-bearing filaments.

Comments: Marine, inhabiting shaded spots such as under boulders, in crevices and caves, and under docks, always above high-tide level. Known from northern Spain to Sweden and the Baltic, Iceland, Greenland, Newfoundland and Maine, and British Columbia.
Numbers of names and species: There are 13 species names in the database at present, as well as 2 infraspecific names. Of the species names, 6 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

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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