Lactifluus vellereus

Lactifluus vellereus, commonly known as the woolly milkcap, is a species of mushroom belonging to the genus Lactifluus within the family Russulaceae. This mushroom is notable for its distinctive woolly white cap and the milky fluid it exudes when cut or broken. It is found in various parts of Europe and North America, typically growing in deciduous and coniferous forests, forming mycorrhizal associations with a wide range of trees.

Description

Lactifluus vellereus features a large, white to cream-colored cap, which can reach up to 15 cm in diameter. The cap surface is dry and covered in a woolly or felty texture, giving the mushroom its common name. The edges of the cap are often rolled inward. The gills are white, closely spaced, and attached to the stem, which is also white and robust, measuring up to 6 cm in height and 2 cm in diameter. When damaged, the mushroom exudes a white, milky latex that does not change color upon exposure to air, a characteristic feature of many Lactifluus species.

Habitat and Distribution

Lactifluus vellereus is primarily found in temperate regions of Europe and has been reported in various parts of North America. It prefers calcareous soils and is commonly found in both deciduous forests, particularly under oaks and beeches, and in coniferous forests, often associating with pines and spruces. The fruiting season extends from late summer to autumn.

Edibility

The edibility of Lactifluus vellereus is a subject of debate, with some sources describing it as edible while others advise against consumption due to its bitter taste and potential for causing gastrointestinal upset. If considered for consumption, thorough cooking is recommended to mitigate any adverse effects. However, due to its bitter taste, it is not highly regarded as a culinary mushroom.

Ecological Role

As a mycorrhizal fungus, Lactifluus vellereus plays a crucial role in forest ecosystems by forming symbiotic associations with trees. These associations help improve water and nutrient uptake for the host trees and in return, the fungus receives carbohydrates produced by the tree through photosynthesis. This mutualistic relationship is vital for the health and sustainability of forest ecosystems.

Conservation

Currently, there are no specific conservation concerns for Lactifluus vellereus, as it is relatively widespread and not considered rare. However, like many fungi, its presence is dependent on the health of its habitat, making it susceptible to the effects of deforestation, pollution, and climate change.
