(Massee & Rodway ex Rodway) Singer & A.H.Sm. (1960)
Cystangium is a genus of fungi in the family Russulaceae. The genus contains 32 species that are distributed in Australia and South America.[1]Cystangium was described by American mycologists Rolf Singer and Alexander H. Smith in 1960.[2]
The taxon is phylogenetically part of Russula and thus probably a synonym.[3] However, it has not been formally synonymised yet and continues to be used by taxonomists.[4][5]
