Key words:  Two new species are described from Fennoscandia, Russula olivina Ruotsalainen & Vauras and Russula taigarum Ruotsalainen & Vauras. Both are boreal fungi growing in moist rich forests with Picea abies, and characterized by their mild taste, and pileipellis with dermatocystidia and without encrusted elements. Further characteristics for R. olivina are the greenish pileus, 2-spored basidia and large spores with isolated spines, while R. taigarum has a matt brown-red pileus and stipe with unevenly distributed red colour. R. postiana Romell is lectotypified.
