Lepidostromatales is an order of fungi in the class Agaricomycetes. It is the only known order of basidiomycete fungi composed entirely of lichenized members. Morphologically, the fruiting bodies of all species are clavarioid. Six species are known, five of which were described within the span of 2007–2013. Due to its morphological similarity to the genus Multiclavula, its isolated phylogenetic position (distinct from all other orders based on molecular data) was not understood until quite recently. The photobionts that have been found in association with members of this group are not known

Punctelia caseana is a species of foliose lichen in the family Parmeliaceae. Its range covers eastern North America, extending south to central and northern Mexico, where it grows on the bark of many species of hardwood and conifer trees.

Crespoa is a genus of five species of lichen in the family Parmeliaceae. Species in this genus are characterized by having an upper thallus surface that is wrinkled and reticulately ridged to coarsely foveolate (having small pits or depressions).

Andreiomyces is the sole genus in Andreiomycetaceae, a family in the order Arthoniales. Andreiomyces contains two lichen-forming fungi, both of which were previously classified in the genus Lepraria.

Sulzbacheromyces caatingae is a species of basidiolichen in the family Lepidostromataceae. Discovered in 2012 in northeastern Brazil, it is characterised by its thin green crustose thallus and distinctive orange-pink, club-shaped reproductive structures. The species has a broad ecological amplitude, occurring across different vegetation types from the semi-arid Caatinga to humid Atlantic Forest fragments, where it grows on soil banks and termite nests near forest edges. As the type species of the genus Sulzbacheromyces, it represents a unique evolutionary lineage within the order

Punctelia eganii is a rare species of foliose lichen in the family Parmeliaceae. It was described in 2011 from a single population found in a beech-magnolia forest along the Alabama River and was named in honor of American lichenologist Robert S. Egan. The lichen appears very similar to the common species Punctelia rudecta, but can be distinguished by tiny white pores that glow bright yellow under ultraviolet light due to the chemical compound lichexanthone, otherwise unknown to occur in the genus. It is known only from its original discovery site in coastal Alabama, where habitat destruction

The Graphidaceae are a family of lichen-forming fungi in the order Graphidales. The family contains nearly a hundred genera and more than 2000 species. Although the family has a cosmopolitan distribution, most Graphidaceae species occur in tropical regions, and typically grow on bark. These lichens are characterized by their crust-like growth form and typically partner with orange-pigmented Trentepohlia algae. Many species produce distinctive elongated, slit-like fruiting bodies, and some have unusually large ascospores that can begin germinating almost immediately upon release. The family

Sulzbacheromyces is a genus of basidiolichens in the family Lepidostromataceae (the only family within the fungal order Lepidostromatales). The genus is distinguished from the other genera of Lepidostromataceae (Ertzia and Lepidostroma) by having an entirely crustose thallus and from Multiclavula (Cantharellales) by having a chlorococcoid (instead of coccomyxoid) photobiont. The type species grows on soil in the neotropics.

Leprocaulon coriense is a species of leprose lichen in the family Stereocaulaceae. It is found in Asia and Australia where it grows on various substrates, including rock, wood, bark, mosses and soil.

Leprocaulon adhaerens is a species of leprose lichen in the family Leprocaulaceae, found in North America. It was originally described in 2007 as Lepraria adhaerens and later transferred to the genus Leprocaulon in 2013 based on molecular and morphological studies. The lichen forms a granular crust that adheres tightly to both the substrate (usually rocks) and itself, often growing over mosses and other lichens. It is chemically distinct due to its production of pannarin, zeorin, and several minor secondary metabolites. The species is known from coastal southern California, Pennsylvania, and

Lepidostroma vilgalysii is a species of basidiolichen in the family Lepidostromataceae. Discovered in 2012 in Mexico's Trans-Mexican Volcanic Belt, it grows in small green patches on clay banks in high-altitude pine forests. The species is distinctive because of its unusual "window lichen" structure, where its algal partner is concentrated in a layer at the base rather than near the surface as in most lichens. Its most distinctive features are its club-shaped reproductive structures, which are pale yellow to orange-brown with cream-colored tips, and its scale-like body parts that have white,

Ertzia is a monospecific genus in the family Lepidostromataceae (the only family within the fungal order Lepidostromatales). The sole species is Ertzia akagerae, a basidiolichen. The genus was circumscribed in 2014 by Brendan Hodkinson and Robert Lücking. Ertzia is distinguished from all other lichenized clavarioid fungi (Multiclavula (Cantharellales), Lepidostroma (Lepidostromatales), and Sulzbacheromyces (Lepidostromatales)) by having a microsquamulose thallus that forms contiguous glomerules (reminiscent of a 'Botrydina-type' thallus) with a cortex of jigsaw puzzle-shaped cells. Ertzia
