Russula subnigricans is a basidiomycete mushroom of the genus Russula found in China and North America. It has been responsible for mushroom poisoning in Taiwan. The effect was a serious one, rhabdomyolysis. Several active agents have been isolated; one designated russuphelin A by researchers in Japan.[1]
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].
