Reader Penny Harris took this picture in her woods in Cambridge, Vermont. What’s the black growth?
Answer
A chaga mushroom (Inonotus obliquus). The burnt-looking part is not a fruiting body, but a mass of mycelium. “Chaga mushrooms are fairly rare and used medicinally,” writes Harris. “They will reportedly stimulate an under-active immune system and have been used in cancer therapy. I aim to make tea with mine and can’t wait to see what it tastes like!”
