sulphur shelf; chicken-of-the-woods
A bright yellow-orange bracket fungus that grows on trees, known for its edible, chicken-like texture when young.
I found a large chicken-of-the-woods in the forest.
Chicken-of-the-woods is edible when young.
The name マスタケ (鱒茸) literally means 'trout mushroom', possibly from its color or appearance, but the exact derivation is uncertain.
