Edibility
Lactarius vietus milk has a very hot taste, and the mushroom lacks a distinctive smell. Although described by many mycologists as inedible, David Pegler claims that its acrid taste can be removed after boiling, allowing it to be consumed. Though the strong, acrid taste is a defining feature of the species, it is weaker or even absent in some older mushrooms, which is not unusual for Lactarius species. Occasionally, however, mushrooms of the species have been collected which have a mild taste; this has also been observed in other species with typically acrid tastes.
