Description: Thallus erect, epilithic or epiphytic, cylindrical, branched, attached to substratum with a minute discoid holdfast. Axis with leading filament which is a monopodium terminating in an assimilatory filament. Meristematic region above and among youngest ramifications. Internal downward growing hyphae absent. Cortex composed of assimilatory filaments, phaeophycean hairs, and reproductive organs. Assimilatory filaments of one kind, curved, with cylindrical to barrel-shaped cells below and moniliform above. Unilocular sporangia globular to pyriform, borne at base of assimilatory filaments within cortex. Plurilocular sporangia not known. Life history alternation of heteromorphic generations with microscopic "streblonematoid" gametophytes and macroscopic sporophyte (Parke 1933). Gamete fusions not seen and sexuality in Mesogloia needs confirmation. Distributed in Europe from Spain to Norway.

Numbers of names and species: There are 39 species names in the database at present, as well as 2 infraspecific names. Of the species names, 7 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
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
