Lejeunea primordialis View in CoL is endemic to southern temperate Australasia including Tasmania and New Zealand, and the subantarctic Auckland Islands. It is a distinctive species that can be recognised by the relatively small shoot width, the tendency to form near pure bright yellow-green turfs on branches and twigs, the ovate-triangular leaves, which taper to a distinct rounded or even obtuse apex, the production of microphyllous cladia, which are often fairly long and which dislocate from normal leafy shoots at their base, and the remote, rather squat underleaves. Lejeunea primordialis View in CoL is usually found in higher-elevation forest and scrub as an epiphyte in well-lit situations.
