Russula pyriodora is a rare species of mushroom-forming fungus in the family Russulaceae, formally described in 2011. The mushroom features a pink to rosy cap, whitish gills, and has a distinctive pear-like odour which inspired its name (from Latin pyri- meaning pear). It has been found only in specific brook-ravine sites in eastern Finland with limestone-influenced soils. The species forms mycorrhizal relationships primarily with birch trees and produces fruit bodies in late summer.
