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."[2] 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.[3] The genus name combines the Latin word perennis ("perennial") with the genus name Poria Edalat.[4]
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 conservePerenniporiella with P. medulla-panis as the type.[3]
