Perenniporia is a cosmopolitan genus of bracket-forming or crust-like polypores in the family Polyporaceae. They are dimitic or trimitic with smooth, thick-walled basidiospores and cause a white rot in affected wood.

Taxonomy

Perenniporia was proposed by American mycologist William Alphonso Murrill in 1943 to contain two species formerly placed in Poria, a genus formerly used to contain all crust-like poroid fungi. His description of the genus was: "Hymenophore become perennial, riding; context white or yellow; tubes pinkish, white or yellow, stratose in older specimens; spores hyaline."[1] Murrill's concept was to move the species with annual fruit bodies (Poria unita and Poria nigriscens) into Perenniporia, retaining Poria for those that produced perennial fruit bodies.[2] The genus name combines the Latin word perennis ("perennial") with the genus name Poria Edalat.[3]

Murrill's designated type species, P. unita, had a broad and poorly defined species concept that included other species, including Perenniporia medulla-panis. Additionally, P. unita was discovered to be a nomen dubium, which also threatened the validity of the genus Perenniporia. To remedy this nomenclatural instability, Cony Decock and Joost Stalpers proposed to conserve Perenniporiella with P. medulla-panis as the type.[2]

Although Truncospora has traditionally been considered a synonym of Perenniporia, molecular phylogenetic analysis shows that it is genetically unique and worthy of recognition as a distinct genus.[4] Genera that have been segregated from Perenniporia include Perenniporiopsis[5] and Perenniporiella.[6]
