Lactifluus volemus

Lactifluus volemus, commonly known as the weeping milk cap or the volemus, is a species of mushroom in the family Russulaceae. This fungus is notable for its distinctive milky discharge, which is a characteristic feature of the genus Lactifluus (formerly part of Lactarius). The species name "volemus" is derived from Latin, meaning "full of moisture," which aptly describes the mushroom's wet surface and the copious amounts of milk it exudes when cut or broken.

Description

Lactifluus volemus features a large, fleshy cap that can range in color from a light tan to a rich, orange-brown. The cap typically measures 5 to 15 cm in diameter and has a convex shape that flattens with age, often developing a central depression. The edges of the cap are initially curled inward. The gills are closely spaced, running down the stem, and are the same color or slightly lighter than the cap. The stem is robust, measuring 2 to 6 cm in height and 1 to 2.5 cm in width, with a smooth surface.

One of the most distinctive features of this mushroom is its milky latex, which is abundant, thick, and creamy. The latex does not change color upon exposure to air, remaining white or slightly yellowish. This milk has a mild taste initially, becoming slightly acrid or bitter after a few moments.

Habitat and Distribution

Lactifluus volemus is a mycorrhizal fungus, forming symbiotic relationships with the roots of hardwood trees, particularly oaks (Quercus spp.). It is found in deciduous forests across North America, Europe, and parts of Asia, thriving in warm, humid conditions during the late summer and early fall.

Edibility

The weeping milk cap is considered an edible mushroom, prized for its rich flavor and meaty texture. It is often collected for consumption, although the milky latex should be allowed to drain or be cooked off to avoid bitterness. In some cultures, Lactifluus volemus is a sought-after delicacy, used in a variety of culinary dishes.

Conservation

Currently, there are no major conservation concerns for Lactifluus volemus, as it is relatively widespread and common in suitable habitats. However, like all wild mushrooms, it should be harvested sustainably to ensure long-term viability of populations.
