Holotype species: Peterfiella alata Gerloff

Original publication and holotype designation: Gerloff, J. (1940). Beiträge zur Kenntnis der Variabilität und Systematik der Gattung Chlamydomonas. Archiv für Protistenkunde 94: 311-502.

Description: Unicellular thalli ellipsoidal to cylindrical. Two anterior isokont flagella. Small papillum may be present. Stigma present. Chloroplast cup-shaped but lacking pyrenoids. Uninucleate with centrally positioned nucleus. Cell wall appressed to the protoplast at the posterior pole but expanding into a a flattened, wing-like appendage at the anterior pole. The wall flattens in a single plane, parallel to the long axis of the cell and to the plane of flagellar insertion, giving the appearance of two anterior wings or keels. Two apical contractile vacuoles. Asexual reproduction by zoosporogenesis resulting in four daughter zoospores. First division is longitudinal without any rotation of the protoplast. Palmella stages with copious mucilage have been reported. No sexual stages have been observed in this genus. Peterfiella has (apparently) only been reported from Rumania. No ultrastructural, biochemical, or molecular data are available for this organism.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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