Xerochlorella Fucíková, P.O.Lewis & L.A.Lewis, 2014

Holotype species: Xerochlorella olmiae Fucíková, P.O.Lewis & L.A.Lewis

Currently accepted name for the type species: Xerochlorella minuta (J.B.Petersen) Mikhailyuk & P.M.Tsarenko

Original publication and holotype designation: Fucíková, K., Lewis, P.O. & Lewis, L.A. (2014). Widespread desert affiliation of Trebouxiophycean algae (Trebouxiophyceae, Chlorophyta) including discovery of three new desert genera. Phycological Research 62(4): 294-305, 5 figures, 1 table.

Description: Cells solitary or in colonies surrounded by delicate mucilage envelopes. Cells ovoid to wide ellipsoid and almost spherical, thin-walled, uninucleate, connected to fragments of mother (sporangial) walls with their narrow ends (Dictyosphaerium- like morphology). Chloroplasts single, parietal, cup-shaped, with pyrenoid surrounded by several starch grains. Asexual reproduction via autospores. Autospores released by rupture of sporangial wall and further preservation of fragments with connected cells. Sexual reproduction not observed.

Taxonomic status: This name is of an entity that is currently accepted taxonomically.

Gender: This genus name is currently treated as feminine.

Most recent taxonomic treatment adopted: Mikhailyuk,T., Holzinger, A., Tsarenko, P., Glaser, K., Demchenko, E. & Karsten, U. (2020). Dictyosphaerium-like morphotype in terrestrial algae: what is Xerochlorella (Trebouxiophyceae, Chlorophyta)?. Journal of Phycology 56: 671-686, 7 figs.

Comments: "Cells spherical to ovoid, thin-walled, uninucleate. Chloroplasts single in young cells, multiple in mature cells. Pyrenoids not observed. Asexual reproduction via autospores. Sexual reproduction not known. Differentiated from other genera in Trebouxiophyceae by 18S rRNA and rbcL gene sequences." (Original description).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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