The Baeomycetales are an order of mostly lichen-forming fungi in the subclass Ostropomycetidae, in the class Lecanoromycetes. It contains 8 families, 33 genera and about 170 species. As a result of molecular phylogenetics research published in the late 2010s, several orders were folded into the Baeomycetales, resulting in a substantial increase in the number of taxa.

The Candelariales are an order of fungi in the monotypic class Candelariomycetes. It contains the families Candelariaceae and Pycnoraceae. The order was circumscribed by Jolanta Miadlikowska, François Lutzoni, and Helge Thorsten Lumbsch as part of a comprehensive phylogenetic classification of the kingdom Fungi published in 2007. The class Candelariomycetes was proposed in 2018 by Hermann Voglmayr and Walter Jaklitsch.
