Rhizopogon evadens is a truffle-like fungus in the family Rhizopogonaceae. Found in North America, it was described as new to science by American mycologist Alexander H. Smith in 1966.[2] The fungus produces roundish to irregularly shaped fruitbodies measuring 2–5 cm (0.8–2.0 in) in diameter, with irregular lobes, wrinkles and depressions on the surface.[3] The peridium (outer tissue layer of the fruitbody) is whitish with light yellow to brown stains, and bruises red. The fungus has an unpleasant odor and a taste described as "metallic". Typical tree associates include pine, Douglas fir, and hemlock.[4] Initially white, the gleba (the interior contents) turn olive to olive-brown in maturity, with the contents developing a gelatinous consistency.[3] The smooth spores of R. evadens are narrowly ellipsoid in shape, and measure 6–8 by 2–2.3 µm.[4]
