The rare ''Russula azurea'' also has a purple cap and grows beneath spruces. ''Russula amethystina'' can hardly be distinguished from this mushroom, its blue to reddish-violet cap occasionally has pale patches and also a smell of iodine in the stem base. It can be found in coniferous mountain forests, mostly under silver fir.References:
