Great Basin Naturalist


Basidiocarps of Pisolithus tinctorius, a gasteromycetous fungus adapted to harsh sites, were observed in association with Jeffrey and Sierra lodgepole pine on acid mine spoils in northeastern California. Subterranean mycelial strands were traced from these basidiocarps to the root systems of the two pine species, which had ectomycorrhizae characteristics of those formed by this fungus in symbiotic relationships with conifer hosts.
