Russula subnigricans, known as Nisekurohatsu (Japanese), is a basidiomycete mushroom of the genus Russula found in China, Japan, and North America. It has been responsible for mushroom poisoning in Taiwan and Japan. The effect was a serious one, rhabdomyolysis. Several active agents have been isolated; one designated russuphelin A by researchers in Japan.[1]
The flesh turns pale red when cut, but doesn't turn black unlike R. nigricans.
The species was named by Japanese mycologist Tsuguo Hongo in 1955. The name has also been applied to a North American fungus Russula eccentrica.[2]
The toxin has been identified as cycloprop-2-ene carboxylic acid and has only four carbon atoms.[3]
