Lactarius rufulus

Lactarius rufulus is a species of mushroom belonging to the genus Lactarius, which is part of the large family Russulaceae. This group of mushrooms is known for their milky latex, which is exuded when the flesh of the mushroom is broken or cut. The species name rufulus is derived from Latin, meaning reddish or rufous, which describes the coloration of the mushroom.

Description

Lactarius rufulus features a cap that ranges from 4 to 10 cm in diameter, initially convex before becoming more flattened or slightly depressed in the center with age. The cap's surface is smooth, with a color palette that includes shades of cinnamon, rufous, or ochre. The margin of the cap is initially inrolled but straightens out as the mushroom matures.

The gills of Lactarius rufulus are adnate to slightly decurrent, close, and cream to pale yellow in color, often becoming spotted or blemished with age. The stem is 2 to 6 cm long and 1 to 2 cm thick, more or less equal in width along its length, and bears the same color as the cap or slightly lighter.

One of the defining characteristics of this species is its milky latex, which is white and does not change color upon exposure to air. The latex has a mild to slightly acrid taste, which can help in distinguishing Lactarius rufulus from other similar-looking species.

Habitat and Distribution

Lactarius rufulus is primarily found in forests, forming mycorrhizal relationships with hardwood trees, especially oaks (Quercus spp.). This symbiotic relationship is crucial for the nutrient exchange between the fungus and its host tree. The species is more commonly encountered in North America, particularly in eastern and northeastern regions, where it fruits from late summer to fall.

Edibility

The edibility of Lactarius rufulus is considered questionable. While not toxic, its mild to slightly acrid taste makes it less desirable for culinary use. As with many wild mushrooms, it is essential to exercise caution and consult with experts before consuming any foraged specimens due to the risk of confusion with potentially toxic species.

Conservation

There are no specific conservation concerns for Lactarius rufulus at present. However, like many fungi, its populations are dependent on healthy forest ecosystems. Conservation of its natural habitats is crucial for the sustainability of this species.
