Lecanoraia

Lecanoraia is a genus of lichenized fungi in the family Lecanoraceae. These lichens are typically crustose, meaning they grow as a flat, encrusting layer on various substrates, often rocks and bark. They are characterized by their lecanorine apothecia, which are disc-shaped fruiting bodies with a thallus-like margin. The thallus of Lecanoraia species can vary in color, often appearing grey, greenish, or yellowish, and can be smooth or somewhat granular.

The species within Lecanoraia are found in a range of habitats, from temperate to alpine regions. They are generally slow-growing and can persist for many years. Their ecological role involves contributing to soil formation through weathering of rock substrates and providing habitat for invertebrates. Identification of Lecanoraia species often relies on microscopic examination of their ascospores, as well as chemical spot tests to detect specific secondary metabolites. The exact number of species and their taxonomic relationships are subject to ongoing research and revision.
