Description: Cells are solitary, spherical to apple shaped with a marked apical depression from which the single flagellum is protruding. The flagellum has a wing with a paraxial rod, and bears two rows of tripartite tubular hairs. A smooth trailing stalk is protruding from the antapical end. Six parietal golden-brown chloroplasts without pyrenoids are arranged radially around the central nucleus from which submicroscopical microtubules in triads are protruding towards the apical surface, but not emanating into tentacles. The cell body is covered by flattened oval organic scales with a thickened rim. Cysts with a three-layered not silicified wall. Nutrition phototrophic. Asexual reproduction by longitudinal fission. M.arctica is cryophilic, found in Arctic marine waters.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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