Brigantiaeaceae Letrouitiaceae Megalosporaceae Teloschistaceae The Teloschistales are an order of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota.

According to one 2008 estimate, the order contains 5 families, 66 genera, and 1954 species.

[1] The predominant photobiont partners for the Teloschistales are green algae from the genera Trebouxia and Asterochloris.

[2] The higher-level phylogenetic relationships of the Teloschistales and other members of the two major subclasses of Lecanoromycetes, Lecanoromycetidae and Ostropomycetidae, were clarified in a 2018 publication by Kraichak and colleagues.
