Pseudomuriella is a genus of green algae, specifically of the class Chlorophyceae. It is the sole genus of the family Pseudomuriellaceae. [1] It is a terrestrial alga that inhabits soils. [4]
Pseudomuriella consists of solitary, spheroidal cells surrounded by a smooth cell wall. Young cells have a single nucleus, but mature cells have nuclei (i.e. are multinucleate). Each cell has multiple chloroplasts lining the outside of the cell; each chloroplast is saucer-shaped when young and divided into multiple segments when older. Chloroplasts lack pyrenoids. [3] Cells may have secondary carotenoids present, giving the cells an orange color especially when old. [3] Pseudomuriella reproduces asexually, mainly by autospores, [3] but sometimes by aplanospores or biflagellated zoospores as well. [4]
Morphologically, the genus is essentially indistinguishable from Bracteacoccus and Chromochloris, although Pseudomuriella seems to reproduce mostly by autospores. [3] Molecular data is necessary for a reliable identification. [5]
