Opeltiella is a genus of lichen-forming fungi in the family Candelariaceae.[1] The genus, established by Sergey Kondratyuk in 2020, has four species.[2] It is differentiated from the similar genus Candelaria by its unique features such as eight-spored asci and absence of a lower cortical layer and true rhizines. The genus is characterised by its areolate to more or less squamulose or foliose thallus and the unique chemical substances it contains, such as calycin, pulvinic and vulpinic acids, and pulvinic acid lactone.
