Phaeoplaca Chodat, 1926

Holotype species: Phaeoplaca thallosa Chodat

Original publication and holotype designation: Chodat, R., Raineri, R & Drew, K. (1926). Algues de la region du Grand St. Bernard III. Bulletin de la Société Botanique de Genève, série II 17: 202-217.

Description: Cells arranged in a one-layered disc-shapedpseudoparenchymatous thallus, epiphytic, mostly onfilamentous algae. Cells box-shaped, containing a brown 2-lobed chloroplast with pyrenoid, sometimes bearing mucilaginous bristles (pseudoflagella). Reproduction by cell division in two directions; amoeboidaplanospores without flagella, and swarmers with one visible long flagellum have been seen. With the electron microscope, a very short second flagellum also has been demonstrated. Epiphytic mostly on other algae in freshwaters of Europe and North America.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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