Aglaothamnion Feldmann-, 1941
Holotype species: Aglaothamnion furcellariae (J.Agardh) Feldmann-Mazoyer
Currently accepted name for the type species: Aglaothamnion tenuissimum (Bonnemaison) Feldmann-Mazoyer
Original publication and holotype designation:
Taxonomic status: currently recognized as a distinct genus.
Most recent taxonomic treatment adopted: Schneider, C.W. & Wynne, M.J. (2007). A synoptic review of the classification of red algal genera a half a century after Kylin's "Die Gattungen der Rhodophyceen". Botanica Marina 50: 197-249.
Description: Thallus filamentous, erect, with a limited or extensive prostrate system, ecorticate or with basal cortication, uniseriate, with 1 lateral branch per axial cell produced in a spiral or alternate-distichous pattern. Cells uninucleate. Spermatangia in clusters, consisting of 1–3- celled fertile axes, adaxial on lateral branchlets. Procarps on unmodified intercalary cells of indeterminate axes, with a supporting cell bearing a 4-celled carpogonial branch. Auxiliary cell(s) arising from the supporting cell and a second fertile pericentral cell borne on the fertile axial cell, following diploidisation forming gonimolobes projecting to each side of the axis, each with a ±triangular profile. Involucral filaments absent. Tetrasporangia solitary and sessile on the adaxial surface of the bearing cell, tetrahedrally divided.

Numbers of names and species: There are 42 species names in the database at present, as well as 4 infraspecific names. Of the species names, 29 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
