Most recent taxonomic treatment adopted: Škaloud, P., Rindi, F., Boedeker, C. & Leliaert, F. (2018). Süßwasserflora von Mitteleuropa. Freshwater flora of central Europe. Bd 13. Chlorophyta: Ulvophyceae (Krienitz, L. ed.). pp. [i]-vii, [1]-288, 182 figs. Berlin: Springer Spektrum.

Description: Thallus filamentous, formed by a prostrate system of creeping filaments from which erect filaments, sparsely to profusely branched, arise. The relative development of the prostrate and erect parts differs among species (sometimes in the same species, depending on the environmental conditions). Specialized rhizoids do not occur. In some species, hair-like, colourless unicellular protuberances are borne on the vegetative cells. Gametangia lateral, terminal, or intercalary, usually borne on the erect filaments but in some species found also on prostrate filaments. The gametangia are globular or ovoid and produce a variable number of biflagellate gametes. The gametes are released through a circular ostiole or an elongated beak, and fuse by isogamy. Sporangiate laterals usually solitary, borne at the top of the erect filaments or short lateral branches; in a few species they are clustered in groups of 2–8 on enlarged apical cells at the top of the erect filaments. The life history is presumed to consist of an alternation of two generations with identical morphology, a haploid gametophyte reproducing sexually by gametes, and a diploid sporophyte reproducing asexually by zoospores. However, direct observations of gametes fusing are infrequent; at the same time, gametes behaving as spores and reproducing new thalli without sexual fusion have been documented for several species.

Comments: Species of Trentepohlia occur on many different substrata (rocks, tree bark, leaves, twigs, fruits, soil, woodwork, carved stone, concrete walls and pillars, metals, plastics), where they may form large orange, red or yellow patches at sites with conditions of high humidity. Often lichenised.

Numbers of names and species: There are 107 species names in the database at present, as well as 57 infraspecific names. Of the species names, 48 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.

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.
