Lecanoropsis

About

Lecanoropsis is a genus of crustose lichens in the family Lecanoraceae. Species in this genus grow mainly on bark and wood, where the body of the lichen is often largely embedded in the substrate rather than forming a conspicuous surface crust. Chemically, they are characterised by usnic acid or the related compound isousnic acid. The genus was validated in 2025 following a molecular study that confirmed it as a distinct lineage, with six species described as new to science in the same revision.
