[Daily article] August 8: Lactarius indigo Published On

Lactarius indigo, commonly known as the indigo milk cap, is a species of
agaric fungus in the family Russulaceae. First described in 1822, it is
a widely distributed species and grows naturally in eastern North
America, East Asia, and Central America; it has also been reported from
southern France. L. indigo grows on the ground in both deciduous and
coniferous forests, where it forms mycorrhizal associations with a broad
range of trees. The cap has a diameter of 5 to 15 cm (2 to 6 in). The
fruit body color ranges from dark blue in fresh specimens to pale blue-
gray in older ones. The milk, or latex, that oozes when the mushroom
tissue is cut or broken—a feature common to all members of the
Lactarius genus—is also indigo blue, but slowly turns green upon
exposure to air. The blue color is due to an organic compound known as
an azulene which is unique to this species, but similar to a compound
found in Lactarius deliciosus. It is an edible mushroom, with a mild to
slightly acrid taste; the firm flesh is best prepared by cutting the
mushroom in thin slices. The blue color disappears with cooking. It is
sold in rural markets in Mexico, Guatemala, and China.

understood by everyone, something that no one ever knew before. But in
the case of poetry, it's the exact opposite!
