Taxonomic status: currently recognized as a distinct genus.

Description: Plants heterotrichous, consisting of sparingly divided uniseriate filaments, branches arise laterally from close to centre of cell, attached by short haptera. Cells uninucleate, barrel-shaped, each with 1 or 2 parietal chloroplasts and without pyrenoids. Asexual reproduction by ellipsoidal zoosporangia and globular akinetes. Sporangia terminal on lateral branches, zoospores dehiscing through a pore and akinetes by a median fracturing of wall. Flagellar number of zoospores unknown. Sexual reproduction unknown. Pleurangium from temporary water in limestone area of China. The illustrations of aplanosporangia accompanying the type description are similar to oogonia depicted for other genera. Pleurangium considered somewhat intermediate between the order Chaetophorales and the Trentepohliales.

Numbers of names and species: There is only one species or infraspecific name in the database at present, which 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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