Lactifluus vellereus in its natural habitat

Lactifluus vellereus, commonly known as the fleecy milkcap, is a species of fungus in the family Russulaceae. It is a large, white, and robust mushroom that is often found in deciduous forests. This species is notable for its thick, velvety cap and the copious amount of latex it exudes when cut or damaged.

Description

Cap

The cap of Lactifluus vellereus is typically 10–25 cm in diameter, making it one of the larger species in the genus. It is convex when young, becoming depressed and funnel-shaped with age. The surface is dry, velvety, and white, sometimes with a yellowish tinge.

Gills

The gills are decurrent, meaning they extend down the stalk, and are white to cream in color. They are closely spaced and exude a white latex when damaged.

Stipe

The stipe, or stem, is stout and short, usually 3–7 cm long and 2–4 cm thick. It is white and smooth, sometimes with a slightly velvety texture.

Spores

The spore print of Lactifluus vellereus is white. The spores are broadly ellipsoid to subglobose, with a reticulate surface.

Latex

The latex of Lactifluus vellereus is white and does not change color upon exposure to air. It is abundant and can cause a mild irritation if it comes into contact with skin.

Habitat and Distribution

Lactifluus vellereus is found in temperate regions of Europe and North America. It grows in deciduous and mixed forests, often in association with oak and beech trees. The species is mycorrhizal, forming symbiotic relationships with the roots of trees.

Edibility

While Lactifluus vellereus is not considered poisonous, it is generally regarded as inedible due to its acrid taste. The latex can cause a burning sensation on the tongue, which makes it unpalatable to most people.

Related Species

Lactifluus vellereus is closely related to other species in the Lactifluus genus, such as Lactifluus piperatus and Lactifluus volemus. These species share similar morphological characteristics but can be distinguished by differences in taste, latex color, and habitat preferences.
