Keriochlamys Pascher, 1943

Holotype species: Keriochlamys styriaca Pascher

Original publication and holotype designation: Pascher, A. (1943). Alpine Algen. I Neue Protococcalengattungen aus der Uralpen. Beihefte zum Botanischen Centralblatt 62: 175-196.

Description: Solitary cells, occasionally clumped into aggregates of 8-12 cells. Cells spherical to broadly ellipsoidal, 8-10 µm diameter. Cells walls 1-1.5 µm thick, inner layer with numerous, contiguous oval bodies giving appearance of unistratose jacket. Outer wall layer smooth and gently rounded above inner wall structures. Cells uninucleate; chloroplast single and band shaped with oval pyrenoid. Asexual reproduction by autospores, 2-4 spores per cells; released by rupture of parental wall. Autospores initially with homogenous walls, but develop characteristic walls prior to release. Flagellates stages and sexual reproduction unknown. Keriochlamys planktonic in freshwater; known only from original description from Europe and single record from Kansas. Affinities at family, order and class level unclear and require ultrastructural and biochemical studies for evaluation. Cell wall structure highly distinctive and should facilitate identification.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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