Observations on a new species of Crucigenia Morren (Chlorococcales)

Phycologia, 1971
Abstract Structure and reproduction of a new species of Crucigenia, C. mitrii sp. nov., isolated from a waste water drain at Allahabad (India) are described. The species is comparable to C. quadrata Morren and C. triangularis (Chodat) Schmidle, but is distinct in shape of colony, the formation of two autocolonies in each parent cell of a mother ...

Control of colony formation in Coelastrum microporum (Chlorococcales, Chlorophyta)

Phycologia, 1976
Abstract Colony formation in Coelastrum microporum Naeg. strains 280 and 281 could be controlled by adding 0.75 g l−1 Na3 citrate and 0.1% (v/v) soil extract to modified Bristol's medium with 0.25 g l−1 CaCl2. When growing in this medium, 92% of colonies in strain 280 and 88% in strain 281 could be obtained.

Chlorococcum littorale, a New Marine Green Coccoid Alga (Chlorococcales, Chlorophyceae)

Archiv für Protistenkunde, 1994
Summary A description of the new marine species Chlorococcum littorale Chihara, Nakayama et Inouye (Chlorococcales, Chlorophyceae) is presented. Unicellular green spheroidal cells were isolated from a saline pond artificially made at Heita Bay, Kamaishi City, in northern Japan. The alga has characteristic features of Chlorococcum and is similar to C.

Observations on Urnella terrestris Playfair (Chlorophyceae, Chlorococcales) in culture

Phycologia, 1981
Abstract The monospecific green alga Urnella terrestris Playfair (1918), isolated from soil of Nepal, was studied in culture. Vegetative cells are coenocytic and produce coenocysts arranged in a row; the chloroplast is parietal with pyrenoids, and zoospores are walled. On the basis of this isolate, the generic and specific descriptions were emended.

Review of the genusLagerheimia Chod. incl.Chodatella Lemm. (Chlorococcales, Chlorophyceae)

Schweizerische Zeitschrift für Hydrologie, 1983
A short review of the history of the taxonomy of the genusLagerheimia incl.Chodatella with a key for 13 accepted species and a table of characteristics of the individual species is given. Members of unicellular green algae of the genusLagerheimia Chod. 1895 (Oocystaceae, Chlorococcales, Chlorophyceae) are strictly planktonic freshwater organisms.

Distribution of the Palynomorph Group: Phytoplankton Subgroup, Chlorococcale Algae

1995
Botryococcus braunii has a cosmopolitan distribution in modern permanent to semipermanent ponds, lakes and rivers ranging from tropical to arctic latitudes (Blackburn, 1936; Aaronson et al., 1983, p. 694). It is most abundant in slow-flowing and lacustrine regimes (Traverse, 1992, p. 123).

Scenedesmus trainorii sp. nov. (Chlorophyta, Chlorococcales): a polymorphic species

Phycologia, 1975
Abstract This description of Scenedesmus trainorii sp. nov. represents the first time that a polymorphic alga has been classified using a combination of morphological and physiological attributes. The two morphological types, colonies and unicells, are identified as forma quadricauda and forma trainorii respectively.

GRAZER‐INDUCED COENOBIAL FORMATION IN CLONAL CULTURES OF SCENENDESMUS OBLIQUUS (CHLOROCOCCALES, CHLOROPHYCEAE)

Journal of Phycology, 1999
Five strains of the phenotypically plastic alga Scenedesmus obliquus (Turpin) Kützing were cultured in standard medium or in medium containing filtered water from a Daphnia culture to examine grazer‐induced coenobia formation. Strains varied considerably in their response to Daphnia chemicals.
