Nephrococcus Y.-Y.Li, 1984
Holotype species: Nephrococcus confertus Y.-Y.Li
Original publication and holotype designation: Li Yao-ying [Li, Y.-Y.] (1984). New cyanophytes from Xizang (Tibet). Acta Phytotaxonomica Sinica 22(2): 167-174, 3 figs. [in Chinese and Latin]
Request PDFDescription: Unicellular-colonial; colonies microscopic, spherical, with one to many (64) cells irregularly or slightly tangentially agglomerated in the center of a colony; the cells are enveloped by more or less narrow, own, fine, hyaline or slightly lamellated sheaths, and their groups are situated in a wide, colorless or yellowish gelatinous envelope, which is slightly concentrically lamellated on the periphery and firmly limited. Cells oval and usually slightly arcuated up to kidney-shaped, with rounded ends, later irregular, rounded-polygonal. Cell content yellowish or blue-green, homogeneous, with scattered small granules. Cell division transverse and later in different planes in successive generations, forming tangentially oriented cells in a colony. The cells reach Å their original size, but not shape before the next division. Reproduction by the dissociation of the colony. The single (type) species grows aerophytically among other algae on the bark of trees in mountains (1140 m), so far known only from China (the upper river Xin-pen). Populations representing probably another species of this genus are found on wet rocks in Asian mountains.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
