Description: Little known until EM study of the type by Rosowski and Lee (1978) showed Euglena-like pellicle and flagella, and a single chloroplast. Separation from Euglena or, more exactly, Phacus seems hard to justify. Freshwater; Europe, Australia and Manchuria. Emended by Kosmala & Zakrys in Kosmala et al. 2007: 180: Cells rigid, ovoid in lateral broad view, laterally compressed with a median longitudinal furrow on one broad side (resembling a coffee bean), without a conspicuous, hyaline, posterior tail; pellicle distinctly striated; single parietal chloroplast forms an open cylinder (in the shape of the letter C without pyrenoids; two lateral, shield-shaped paramylon grains (located between the chloroplast and the pellicle). Emend. Marin & Melkonian (in Marin et al. 2003: 101)Emend. Kosmala & Zakrys (2007: 180).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
