Pyrofomes is a genus of fungi in the family Polyporaceae. The genus was circumscribed by Czech mycologists František Kotlaba and Zdenek Pouzar in 1964. The type species, Pyrofomes demidoffii, was once considered a widespread species with a distribution that included East Africa, Middle Asia, Europe, and North America. DNA evidence demonstrated that North American collections represented a lineage that was different than European collections. The North American sibling was reinstated as P. juniperinus in 2017.
