Heterobasidion irregulare the ‘P’ (Pine) type) can kill ponderosa pine, Jeffrey pine, sugar pine, Coulter pine, incense-cedar, western juniper, and pinyon pine; Fruits inside of stumps; popcorns on roots; All of North America

Heterobasidion occidentale the ‘S’ (Spruce/fir) type) can kill true firs, hemlock, Douglas-fir, and giant sequoia. Western North America.

Pine stumps can have either species, but H. occidentale is only found under the intact surface bark of pine stumps. A fruiting body on pine is H. irregulare.
