Mantellum P.J.L.Dangeard, 1941

Holotype species: Mantellum adherens P.J.L.Dangeard

Original publication and holotype designation: Dangeard, P.[J.L.] (1941). Chroococcales, genre Mantellum gen. nov. Le Botaniste 30: 129-131, pl. 2.

Description: Unicellular; cells solitary or in flat groups, arranged in one plane (layer), sometimes more or less in irregular rows, joined to the substrate (by mucilaginous pads ?), but not evidently heteropolar, usually more or less spherical or slightly oval, with homogeneous or slightly granular content. Without mucilage. Attached usually to other filamentous algae. Cell division probably in two planes perpendicular to one another and to the substrate (formation of flat groups). Cells grow more or less to the original size before the next division. Reproduction by liberated solitary daughter cells. Type species described from periphyton on filamentous algae in marine littorals; to this genus belong probably further cyanophytes, which grow attached to similar substrates and which were described as different Xenococcus species (but not reproducing by nanocytes and growing only in spherical cells; e.g. X. gracilis , X. minimus, X. schousboei p.p., etc.).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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