Brehmiella Pascher, 1928

Holotype species: Brehmiella chrysohydra Pascher

Original publication and holotype designation: Pascher, A. (1928). Eine eigenartige rhizopodiale Flagellate. Archiv für Protistenkunde 63: 227-240.

Description: Solitary amoeboid cells lacking flagella. Cell shape obconical or approximately hemispherical, the anterior face bordered by several radiating pseudopodia, posteriorly with a single pseudopodium which attaches the cell to the substratum. Number and shape of anterior pseudopodia variable. Protoplast with 2 contractile vacuoles and a single, pale, bandshaped chloroplast without stigma. Sometimes chloroplast partitioned in more or less separate smaller portions or chloroplast lacking altogether. Occasionally cells may develop 2 unequal flagella resembling Ochromonas, detach from the substrate and swim away. Ingestion of solid food particles mainly at the anterior face or by the anterior pseudopodia. Cells sometimes completely filled with nutritive vacuoles, sometimes distorted by ingestion of very large prey. Reproduction by longitudinal fission in the amoeboid or free-swimming stage. Stomatocysts unknown. Epiphytic on filamentous algae, so far only found in freshwater ponds in Czechia and Russia.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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