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.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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