ABSTRACT: Three hypogeous fungi are reported from a small stand of Douglas-fir and lodgepole pine planted in 1936 by the Civilian Conservaton Corps in the Santa Rosa Range, Nevada. The fungi were probably introduced as ectomycorrhizal symbionts on the roots of seedlings from Utah. The distances to the nearest native stands of trees are too far for rodent transport of inoculum. Other exotic fungi may be expected wherever ectomycorrhizal trees have been planted.
