Lecanora Dispersella
''Lecanora'' is a genus of lichen commonly called rim lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Lichens in the genus ''Squamarina'' are also called rim lichens. 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.
