About Lactarius resimus (Fr.) Fr.
Lactarius resimus (Fr.) Fr. is a mushroom species belonging to the genus Lactarius. When salt-pickled, it is regarded as a delicacy in Russia and several other Eastern European countries, where it is counted among the three tastiest edible mushrooms, alongside Boletus edulis and Lactarius deliciosus. In its raw state, however, it is considered mildly toxic due to its acrid latex. This species forms mycorrhizal associations with birch trees and conifers, particularly pine. It is commonly found across northern and eastern Europe, including Russia, Belarus, Ukraine, the Baltic states, and parts of Scandinavia. It typically grows on acidic soil, and fruiting bodies appear from late summer to autumn. The mushroom's cap has a diameter ranging from 4 to 15 cm (1.6 to 5.9 in), while its stalk measures 2 to 6 cm (0.79 to 2.36 in) in length and 1 to 3 cm (0.39 to 1.18 in) in width. The mushroom is generally white in overall color, but bruises and stains yellow to orange. Its spores are white-yellow, elliptical in shape, and bumpy in texture. Similar species to Lactarius resimus include Lactarius pubescens var. betulae and Lactarius torminosus.
