Members of the genus have roughly circular fruiting discs (apothecia) with rims that have photosynthetic tissue similar to that of the nonfruiting part of the lichen body (thallus). Other lichens with apothecia having margins made of thallus-like tissue are called lecanorine.Lecanora has a crustose thallus, trebouxoid photobiont, colourless ascospores and crystals in the amphitecium.It is in the family Lecanoraceae in the suborder Lecanorineae.
