Bracteacoccus is a genus of green algae, the sole genus of the family Bracteacoccaceae. [1] It is a terrestrial alga commonly found in soils, from the tropics to the poles. [2]
Bracteacoccus was described by E. Tereg in 1922, based on the species Bracteacoccus aggregatus. [2] Later it was synonymized with the genus Dictyococcus, until Richard C. Starr reestablished the genus. [3]
Bracteacoccus consists of solitary, typically spherical cells from 4 to 110 μm in diameter. [2] Mature cells have multiple nuclei (i.e. are multinucleate). Each cell has multiple chloroplasts lining the outer wall of the cell; each chloroplast is angular in shape and lacks pyrenoids. [4]
Bracteacoccus reproduces asexually by producing zoospores. The zoospores have two flagella which are slightly unequal in length. Bracteacoccus may also reproduce by producing non-motile aplanospores. [2]
Morphologically, the genus is essentially indistinguishable from Pseudomuriella and Chromochloris, except for the fact that the latter two genera do not take up fluorescent dyes as easily. [5] The three genera are phylogenetically distinct. [2] It is also similar to the genus Dictyococcus, but Dictyococcus has chloroplasts which are inflected inwards. [3]
As of February 2022 [update], AlgaeBase accepted the following species: [1]
A further species, Bracteacoccus helveticus (Kol & F.Chodat) Starr, was regarded as of "uncertain taxonomic status". [1]
