Yellow-staining milkcap

Lactarius xanthogalactus

A species of Milk-caps.

Similar to the majority of other milkcap fungi, the yellow-staining milkcap exudes a milky, latex-like fluid upon being cut or damaged. However, distinct from its close relatives, this mushroom's latex rapidly transforms into a bright canary-yellow hue upon exposure to air. Feel free to observe this phenomenon firsthand, but remember, this particular species is not suitable for culinary use! The yellow-staining milkcap is poisonous.
