The Boletinellaceae are a small family of mushroom-forming fungi, primarily characterized by small pores on the underside of the cap rather than gills. Though in the order Boletales, research shows they and Gyroporaceae are more closely related to earthballs of Sclerodermataceae than Boletaceae. Genera include Boletinellus and Phlebopus, the latter genus showing some Gondwanan distribution found in Australia, Sri Lanka and elsewhere. It contains the gigantic Phlebopus marginatus, the cap of which can reach 1 metre in diameter.

The Peltigeraceae are a family of lichens in the order Peltigerales. The Peltigeraceae, which contains 15 genera and about 600 species, has recently (2018) been emended to include the families Lobariaceae and Nephromataceae. Many Peltigeraceae species have large and conspicuous, leathery thalli. They largely occur in cool-temperate to tropical montane climates. Tripartite thalli involving fungus, green algae and cyanobacteria are common in this family.

The Doassansiaceae are a family of fungi in the division Basidiomycota and order of Doassansiales. The family contains 11 genera and about 58 species. They have a widespread distribution. Doassansiaceae is also known and classified as a smut fungi. They have parasitic hyphae with clamps, they are also teliosporic (have a thick-walled resting spore) and dimorphic (can be mold or yeasts) as well as not forming ballistoconidia (air discharged spores) in the haploid phase. The do not have haustoria (root-like structures). When the family was originally created (by R. Bauer and Oberw. 1997), it

The Aulographaceae are a family of fungi with an uncertain taxonomic placement in the class Dothideomycetes.

Vezdaea is a genus of crustose lichens in the monotypic family Vezdaeaceae, which itself is the only taxon in the order Vezdaeales. The genus was established in 1976 and named after the Czech lichenologist Antonín Vězda for his contributions to lichen science. These lichens form extremely thin crusts that appear as dustings of tiny greenish to grey particles on decaying moss, plant debris, and soil, particularly in metal-enriched environments that other lichens avoid. The genus contains 14 species.

The Coccotremataceae are a family of lichen-forming fungi in the order Pertusariales. Species in this widely distributed family grow on bark or rocks, especially in maritime regions.

Pachyascus is the sole genus in the family Pachyascaceae. It contains a single species, the lichen Pachyascus lapponicus. Both the genus and species were described as new to science in 1968 by lichenologists Josef Poelt and Hannes Hertel. P. lapponicus was originally collected from Lapland, a province in northern Sweden. The lichen has several unusual characteristics: it grows exclusively along with the rock moss Andreaea, it bears goniocyst-like parts (goniocysts are small aggregations of photobiont cells surrounded by fungal hyphae) and produces tiny apothecia that stand in the leaf axils

Thelenellaceae is a family of lichen-forming fungi. It is the sole family in the monotypic order Thelenellales, and contains three genera and about 50 species.
