Chrysolepidomonas M.C.Peters & R.A.Andersen, 1993
Holotype species: Chrysolepidomonas dendrolepidota M.C.Peters & R.A.Andersen
Original publication and holotype designation: Peters, M.C. & Andersen, R.A. (1993). The fine structure and scale formation of Chrysolepidomonas dendrolepidota gen. et sp. nov. (Chrysolepidomonadaceae fam. nov., Chrysophyceae). Journal of Phycology 29: 469-475.
Request PDFDescription: Cells solitary, free-swimming, rounded to elongate in face view and not or only slightly flattened in side view. At the anterior end with a long flagellum bearing tripartite tubular hairs and a short flagellum lacking hairs (in one speciesthe short flagellum only visible by EM). At least in 2 species, both flagella are also covered by small organic scales of 2 types: one shaped like a flower-pot with a fenestrate, bumpy or spiny distal rim, the other like the former at its base but on top bearing a tree-like outgrowth of variable length terminating ina number of radial arms.In all 3 species known at present, the cell body is also covered by scales of a similar or identical structure.During life the scales appear to be partly enveloped and held in position by some transparent amorphous material. Scale formation is performed within cisternae of the single large Golgi body. Flagellar apparatus resembles that found in Ochromonadaceae, Dinobryaceae and Paraphysomonadaceae. Chloroplast single, parietal, containing a girdle lamella and a stigma; pyrenoid observed in one species. Contractile vacuoles 1-2, located anteriorly. Chrysolaminaran vacuole at the posterior end of the cell. Food vacuoles and phagotrophic feeding not observed. Reproduction not observed in any detail. Stomatocysts known from 2 species. All species rarely observed, 2 species in freshwater lakes and ponds in Europe and USA, one marine species from S. Africa, originally described as a species of Sphaleromantis. Chrysolepidomonas is characterized by the unique scales.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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