SIMILAR SPECIES: amazing double is the type of Boletus rubrosanguineus (Wälty) ex Cheype, which grows at higher elevations in coniferous forests (spruce and fir). Rhodoxanthus while a young pink-grayish shade hat, and rubrosanguineus without significant impurities or slightly rose-colored, but is more grayish okerzelenkast, and how old it turns red while rhodoxanthus remain still pink or even fade.
