Abstract

A single-celled green algaCoccomyxagreatwallensisShunan Cao & Qiming Zhou,sp. nov., isolated from a specimen of Antarctic lichenPsoromahypnorum(Vahl) Gray, is described and illustrated based on a comprehensive investigation of morphology, ultrastructure, ecology and phylogeny. The cells ofC.greatwallensisare ovoid to long ellipsoidal and measured 3–5 µm × 6–12 µm. The new species has distinct ITS rDNA and SSU rDNA sequences and differs from the phylogenetic closely related speciesC.antarctica,C.arvernensisandC.viridisin cell size, distribution and habitat.
