Possible affinities to the genus Jenufa (Nemcova et al. 2011). - (7 Nov 2011) - Wendy Guiry
Description: Unicellular, solitary algae with spherical cells, 10-18 &m diameter, with numerous thin spines 6-65 &m long. Pseudocolonies sometimes formed by interlocking of spines. Thin mucilaginous envelope surrounds cell and base of spines. Cell walls smooth. Cells uninucleate; single chloroplast cup-shaped and parietal with single pyrenoid with starch sheath. Asexual reproduction by quadriflagellate zoospores; 2-4 per sporangium. Zoospores without stigma but with contractile vacuoles. After motile period zoospores lose flagella and develop spines. Aplanospores also described. Sexual reproduction unknown. Golenkinia planktonic in freshwater; one species cosmopolitan, the other only reported from the former USSR. A variety of studies have described ultrastructure and physiology of Golenkinia spp., especially G. paucispina and G. minutissima = G. parvula, however, these taxa have affinities in Golenkiniopsis. Recent floristic work in North America suggests that these genera are not clearly defined and family relationships are unclear. Some authors also include Echinosphaeridium as a synonym, however, they can be distinguished based on ultrastructure of spines.

Numbers of names and species: There are 19 species names in the database at present, as well as 4 infraspecific names. Of the species names, 9 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..
Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
