Original publication: Martius, C.F.P. von (1817). Flora cryptogamica erlangensis sistens vegetabilia e classe ultima Linn. in agro erlangesi hucusque detecta.... pp. [i]-lxviii , [1-2, h. t. and motto], 1-512, 6 folded plates. Norimbergae [Nürnberg]: sumptibus J. L. Schrag.

Taxonomic status: currently regarded as a synonym of .

Description: Branched filaments sometimes heterotrichous but with minimal differentiation of prostrate filaments. Cells cylindrical, often enlongated (length 2, 3 or several times the width) and sometimes inflated or barrel shaped and thus creating moniliform filaments. Initially green but often turning bright orange (due to cytoplasmic accumulation of carotenoids). Cell walls often thick; cells connected by simple plasmodesmata present in central area of crosswalls. Nucleus single; cytokinesis by means of phragmoplast (cf. Cephaleuros). Chloroplasts parietal without pyrenoids. Life history a presumed alternation of isomorphic generations. Producing abscising ovoid zoosporangia typical of order (cf. Cephaleuros) either single and terminal or in clusters, with several suffultory cells attached to each enlarged pyriform head cell. Gametangia terminal; quadriflagellate zoospores and biflagellate gametes typical of order.

Comments: Subaerial on stone, wood, leaves, stems, fruits and tree trunks; cosmopolitan. Common epiphyte of trees in coastal temperate areas with high rainfall; at least one species common in dimly lit caves. Like Cephaleuros and Phycopeltis, Trentepohlia often lichenized.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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