Range

Widely distributed across Africa (9 countries), Asia (7 countries), Europe (11 countries), North America (13 countries), Oceania and the Pacific (11 countries), and South America (6 countries).

Chocolate Milky

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and North America (United States). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Cat

One of humanity's most successful domesticated companions, domestic cats are small, agile carnivores originating from the Near Eastern wildcat (Felis silvestris lybica) domesticated approximately 10,000 years ago. With over 70 recognized breeds, cats retain strong predatory instincts and have colonized virtually every terrestrial environment on Earth. They are the world's most popular pet, with an estimated 600 million kept worldwide.

Chocolate Milky

The Chocolate Milky (Lactarius lignyotus) is a medium-sized ectomycorrhizal mushroom in the family Russulaceae, found in coniferous and mixed forests across Europe, North America, and temperate Asia. Like all members of the genus Lactarius, it exudes a milky latex when the flesh is broken — in L. lignyotus, this latex is white and acrid, contributing to the genus's widespread edibility variation. The fruiting body features a distinctive dark chocolate-brown to sooty-brown, velvety cap with a central boss (umbo), similarly coloured gills, and a dark brown stipe, making it relatively recognisable among forest mushrooms. It grows in close association with spruce (Picea) and fir (Abies) trees, forming ectomycorrhizal symbioses in which the fungal mycelium envelopes root tips and exchanges mineral nutrients for plant photosynthates, a relationship fundamental to the health of boreal and montane conifer forests. The IUCN classifies the chocolate milky as Endangered in certain regional assessments, reflecting declines in suitable habitat quality linked to changes in forest management, nitrogen deposition from atmospheric pollution, and climate change affecting the timing and abundance of fruiting. Accurate population monitoring of ectomycorrhizal fungi is challenging given that the fungal organism itself is largely subterranean, visible only when fruiting.
