Holotype species: Microseira wollei (Farlow ex Gomont) G.B.McGregor & Sendall ex Kenins

Original publication and holotype designation: McGregor, G.B. & B.C.Sendall (2014). Phylogeny and toxicology of Lyngbya wollei (Cyanobacteria, Oscillatoriales) from north-eastern Australia, with a description of Microseira gen. nov. J. Phycol. 51(1): 109-119, 5 fig., 2 tables.

Taxonomic status: currently recognized as a distinct genus.

Description: Freshwater; thallus a prostrate, greenish blue-black woolly mat of densely aggregated filaments. Filaments straight to variously contorted, facultatively and infrequently pseudobranched. Sheath colorless, hyaline, when old distinctly lamellated (roughened) and colored, open at the apex. Trichomes isopolar, uniformly cylindrical, up to 70 µm wide; not or slightly constricted at the cross-walls. Cells discoid, 5–15 times broader than long; contents finely granular, without aerotopes; apical cells rounded, without a calyptra or thickened outer cell wall. Reproduction by motile hormogonia formed by necridia.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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