If there was a beauty contest for fungus, I know one that would probably come in last: chaga. Resembling a black scaly scab on the wound of a birch tree, there is really nothing attractive about it.
But for every point it loses for its ugliness, it makes up for in medicinal qualities. Well, that’s the reputation it has, anyway. It has quite a following among select foragers. However, that could possibly be chalked up to a lack of other things available to gather through the cold months.
