Holotype species: Scotinosphaera paradoxa Klebs

Original publication and holotype designation: Klebs, G.A. (1881). Beiträge zur Kenntniss niederer Algenformen. Botanische Zeitung 39: 249-257, 256-272, 297-308.

Description: Unicellular algae with relatively large cells (up to 400 ?m), spheroid to irregularly shaped, often with one to several local stratified cell wall thickenings. Chloroplast forming a net of numerous radiating and anastomosing lobes expanding from two or more pyrenoids toward the cell periphery. Pyrenoid matrix dissected by numerous anastomosing cytoplasmatic channels. Asexual reproduction by zoospores and autospores. Sporogenesis initiated with accumulation of secondary carotenoids in the cell periphery, followed by a quickly repeated mitosis without parallel cell wall synthesis. Zoospores biflagellate, naked, produced in high numbers. Sexual reproduction not observed. Free-living, rarely endophytic, in freshwater or aeroterrestrial habitats.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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