Holotype species: Scherffelia dubia (Perty) Pascher

Description: Cells ellipsoidal to cylindrical and strongly flattened along the longitudinal axis. Anterior depression defined by four lobes of varying prominence. Cell may be twisted in the flattened plane. Cell wall (=theca) is present and may be thickened along the outer edges of the flattened cell. Cell wall may also appear reddish. Four isokont flagella inserted in a small, but sharply-defined, anterior depression. One or two chloroplasts present, either cup-shaped or flattened. Pyrenoids absent. Stigma normally present. Single central nucleus. Two (rarely three) anterior contractile vacuoles. Asexual reproduction by longitudinal division of the protoplast typically producing four motile daughter. No other asexual stages have been observed. No sexual stages have been observed in this genus.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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