Description

The

Scleroderma).[2]

The variegatic acid is an orange pigment first isolated from Suillus variegatus.[3] It has strong antioxidant properties,[4][5] and a nonspecific inhibitory effect on cytochrome P450 enzymes.[6] When mushroom tissue containing variegatic acid is exposed to air, the chemical is enzymatically oxidized to blue quinone methide anions.[7]

Distribution and habitat

Suillus variegatus appears frequently with, and is

pine trees in late summer. It is often found with heathers, and other acid loving plants, on sandy soils. It is widespread in Europe, nearer parts of Asia,[2] and North America
.

Edibility

Suillus variegatus is edible, but is said to smell unpleasant, with a somewhat metallic taste.[2] It was one of the most productive edible wild mushroom species in Finland in the 1970s.[8]
