Species

Palmellopsis is a genus of green algae, specifically of the Palmellopsidaceae. [1] [2] They are either planktonic or attached to substrates in fresh water, or in aeroterrestrial habitats. [3]

Palmellopsis consists of cells embedded in amorphous, gelatinous mucilage. The cells contain a cup-shaped chloroplast with a pyrenoid, as well as a single nucleus and two contractile vacuoles. [4] [3]

Asexual reproduction in this genus occurs by autospores or zoospores or by the fragmentation of the colonies. Zoospores have two equal flagella with a small stigma. [4]

Palmellopsis is distinguished from the similar genera Palmella [4] and Chlamydocapsa in that its mucilage layer is not lamellated. The differentiation between these genera is taxonomically problematic. [5]
