Monotypic Polyporales genera

Terana is a fungal genus in the family Phanerochaetaceae. It is a monotypic genus, containing the single species Terana caerulea, a widespread crust fungus.

Bridgeoporus is a fungal genus in the family Polyporaceae. A monotypic genus, it contains the single polypore species Bridgeoporus nobilissimus, first described to science in 1949. Commonly known both as the noble polypore and the fuzzy Sandozi, this fungus produces large fruit bodies (or conks) that have been found to weigh up to . The upper surface of the fruit body has a fuzzy or fibrous texture that often supports the growth of algae, bryophytes, or vascular plants.

Trametopsis is a genus of fungi in the family Irpicaceae.

Gelatoporia is a fungal genus in the family Gelatoporiaceae. This is a monotypic genus, containing the single widely distributed species Gelatoporia subvermispora. The genus was circumscribed in 1985 by Finnish mycologist Tuomo Niemelä to contain poroid crust fungi with a monomitic hyphal structure, clamped hyphae, and producing white rot.

Erastia is a fungal genus in the family Polyporaceae. It is a monotypic genus, containing the single European species Erastia salmonicolor, or the salmon bracket. Erastia was circumscribed by Finnish mycologists Tuomo Niemelä and Juha Kinnunen in 2005. It is named in honour of the Estonian mycologist Erast Parmasto, "the eminent researcher of fungal taxonomy and cladistics".

Bulbillomyces is a fungal genus of uncertain familial placement in the order Polyporales. Bulbillomyces is monotypic, containing the single species Bulbillomyces farinosus, a crust fungus. The genus was circumscribed by the Swiss mycologist Walter Jülich in 1974. The fungus was reported as new to Japan in 2002.

Earliella is a fungal genus in the family Polyporaceae. It is a monotypic genus, containing the single species Earliella scabrosa. It is found in Hainan.

Poronidulus is a fungal genus in the family Polyporaceae. It is a monotypic genus, and contains the single polypore species Poronidulus conchifer, found in North America. The genus was circumscribed by American mycologist William Alphonso Murrill in 1904. The generic name, which combines the Ancient Greek word ("pore") with the Latin word nidulus ("small nest"), refers to the superficial similarity of the cup-shaped Poronidulus fruit bodies with those of the genus Nidularia. A second species, Poronidulus bivalvis, found in Bogor, was placed in the genus by Franz Xaver Rudolf von Höhnel in 1914

Parvodontia is a fungal genus in the family Cystostereaceae. This is a monotypic genus, containing the single species Parvodontia luteocystidia, a crust fungus that grows on bamboo in Brazil. Parvodontia was first described in 2004 by Hjortstam and Ryvarden. The genus was established to classify a crust fungus found on bamboo in Brazil.

Austrolentinus is a fungal genus in the family Polyporaceae. Segregated from the genus Lentinus, it is monotypic, containing the single species Austrolentinus tenebrosus, which was first described by E.J.H. Corner in 1981 as Panus tenebrosus. Austrolentinus was circumscribed by Norwegian mycologist Leif Ryvarden in 1991. The fungus occurs in Queensland, Solomon Islands and Papua New Guinea, and the Malay Peninsula.

Sparsitubus is a fungal genus in the family Polyporaceae. It is a monotypic genus, containing the single species Sparsitubus nelumbiformis, found in Hainan and Yunnan, China. Molecular analysis suggests that Sparsitubus is in a clade of white rot polypores and may be closely related to the Ganodermataceae.

Crustodontia is a fungal genus of uncertain familial placement in the order Polyporales. The genus was circumscribed in 2005 to contain the crust fungus Crustodontia chrysocreas. This species was originally described as Corticium chrysocreas by Miles Berkeley and Moses Ashley Curtis in 1873. Their description was as follows: "Subiculum bright yellow, thin; hymenium immarginate pallid, or yellow tinged with tawny." Crustodontia has a monomitic hyphal system, meaning it contains only generative hyphae, and these hyphae have clamp connections.

Atraporiella is a monotypic fungal genus in the family Steccherinaceae. It contains the crust fungus Atraporiella neotropica, known only from Belize.
