Heteroplacidium is a genus of lichen-forming fungi in the family Verrucariaceae. The genus was circumscribed by Austrian lichenologist Othmar Breuss in 1996 with Heteroplacidium imbricatum assigned as the type species. It was proposed as a segregate of Catapyrenium. Other morphologically similar genera are Neocatapyrenium, Placidium, and Scleropyrenium, although molecular phylogenetic analyses indicate that they are independent monophyletic lineages within the Verrucariaceae.

Oevstedalia is a genus of fungi of uncertain placement in the subphylum Pezizomycotina. This is a monotypic genus, containing the single lichen species Oevstedalia antarctica. The genus was circumscribed by Damien Ertz and Paul Diederich in 2004. Previously classified in the Dothideomycetes, Oevstedalia was moved to Pezizomycotina incertae sedis due to the lack of DNA data available for the genus.

Chrysothrix is a genus of lichen-forming fungi in the family Chrysothricaceae. They are commonly called gold dust lichens or sulfur dust lichens, because they are bright yellow to greenish-yellow, sometimes flecked with orange, and composed entirely of powdery soredia. Apothecia are never present in North American specimens.
Xyleborus is a genus of lichen-forming fungi in the family Stereocaulaceae. It has two species. The genus was circumscribed in 2009 by Richard C. Harris and Douglas Ladd with Xyleborus sporodochifer assigned as the type species. A second species, X. nigricans, was added to the genus in 2015.
