Schizochlamydella Korshikov, 1953: 331
Holotype species: Schizochlamydella delicatula (West) Korshikov
Currently accepted name for the type species: Phaeoschizochlamys delicatula (West) Bourrelly
Original publication and holotype designation:Korshikov, O. (1953). Viznachnik prisnovodnihk vodorostey Ukrainsykoi RSR [Vyp] V. Pidklas Protokokovi (Protococcineae). Bakuol'ni (Vacuolales) ta Protokokovi (Protococcales) [The Freshwater Algae of the Ukrainian SSR. V. Sub-Class Protococcineae. Vacuolales and Protococcales]. pp. 1-439. Kyjv [Kiev]: Akad. Nauk URSR.
Taxonomic status: currently regarded as a synonym of Phaeoschizochlamys.
Description: Microscopic unicellular to colonial aggregations of cells embedded in structureless mucilaginous envelope. Colony spherical to amorphous, when colonial with cells generally dispersed in mucilage along with remnants of sporangial walls. Cells spherical, 2-10 &m in diameter with smooth cell walls. Cells uninucleate; chloroplast single and parietal with one to several pyrenoids, pyrenoid difficult to resolve in S. capsulata without staining for starch. Asexual reproduction by autospores; 2-4 (up to 8 in S. sphaerica) spherical to slightly oval spores released through a tear in sporangial wall. Flagellated stages and sexual reproduction unknown. Schizochlamydella planktonic in freshwater (S. solitaria, S. delicatula), isolated from soil (S. spherica, S. delicatula) or from brackish water (S. capsulata). Species reported from Europe, Japan and Florida with Florida only known site for brackish water species. S. capsulata shows growth in 1-37 0/00 seawater and has requirement for vitamin B12. Species of Schizochlamydella previously described as Schizochlamys or Chlorella. Species distinguished based on cell size and number of cells per colony, habitat requirements and chloroplast morphology. According to Bourrelly (1972), the type species, S. delicatula is a chrysophyte and has been placed in Phaeoschizochlamys; however, see comments in Komárek and Fott (1983).

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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