Holotype species: Podohedra longipes Düringer

Original publication: Düringer, I. (1958). Über die Verteilung epiphytischer Algen auf den Blättern wasserbewohnender Angiospermen sowie systematisch-entwicklungsgeschichtliche Bemerkungen über einige grüne Algen. Österreichische Botanische Zeitschrift 105: 1-53.

Description: Solitary, attached (rarely planktonic) cells not embedded in mucilaginous matrix. Cells fusiform to slightly twisted, 16-75 x 1-6 (-9) µm, with elongate, straight or curved projections at both ends, free end attentuate and pointed, attached end with elongate process terminally widened and flattened or rounded. Cell walls smooth. Cells uninucleate; chloroplast single and parietal; pyrenoid single, often with distinct starch sheath. Asexual reproduction by autospores; 2-4 spores per sporangium, formed after oblique divisions of mother cell. Flagellated stages and sexual reproduction unknown. Podohedra in freshwater, one species planktonic, the remainder epiphytic on various substrata including algae and mosses. Species reported mostly from Europe although P. georgei described only from India. Podohedriella Hindák was segregated from Podohedra based on the absence of pyrenoids. Apart from this feature, the two genera are very similar.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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