Genus named for the white, scale-like leaves on the main stem. Species name meaning spiny nerve, probably in reference to the teeth on the back of the midrib.
Sometimes called Mnium menziesii or L. menziesii, both of which are synonyms. Sometimes called "palm tree moss".
The leafy plants that resemble small trees, the white, narrowly triangular leaves on the main stem and the nodding sporangia are useful features. In male plants, the rosette of leaves surrounding the sex organs is distinctive in a dwarf tree-like plant; no other moss in British Columbia resembles it.

Possibly Climacium dendroides might be considered similar, but the broad heart-shaped stem-leaves, the more shiny appressed leaves and the usual presence of a subterranean creeping stem separate Climacium from L. acanthoneuron. Pleuroziopsis ruthenica has plants in which the apical mass of branches forms a horizontally flattened, intricately branched system. Thamnobryum neckeroides also possesses somewhat flattened branched systems but the leafy branches are decidedly swollen compared to Leucolepis. Hypopterygium fauriei also has somewhat flattened but tiny, tree-like shoots but the leafy shoots are also conspicuously flattened with the leaf on the underside of the branch much smaller than the lateral ones; this moss is a calcicole.
