| discussion |
Originally described from Japan, A. fuliginea is very common in China, especially in the central parts. Corner and Bas (1962) compared this species to A. alauda Corner & Bas and A. privigna Corner & Bas. This species is deadly POISONOUS. Many disasters have happened in central China in the last few years due to people's eating this mushroom.—Zhu L. Yang |
