Lecanorais agenusoflichencommonly calledrim lichens.^[1]^: 279^[2]Lichens in the genusSquamarinaare 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).^[1]Other lichens with apothecia having margins made of thallus-like tissue are calledlecanorine.^[1]

It is in the familyLecanoraceaein the suborderLecanorineae.^[3]^[4]

Description

Lecanorahas acrustose thallus,trebouxioidphotobiont,colourlessascosporesand crystals in theamphothecium.^[5]^: 680

Swiss lichenologistRosmarie Honeggerusedelectron microscopyin the late 1970s to investigateascusstructure in several major groups of lichen-forming fungi. She defined theLecanora-type ascus as one characterized by several distinctive features: (1) a non-amyloid,clear ascus wall that is encased in an amyloid outer layer often described as afuzzy coat;(2) an amyloiddomefilled withgranularinclusions set within a clear matrix; (3) a clear central layer inside the dome; and (4) a method of opening, ordehiscence,that is rostrate (resembling the shape of a bird's beak – the ascus has a pointed or protruding tip from which the spores are released).^[6]
