Species of fungus
Russula cupreola is an agaricoid fungal species first typed in 1990. It shows a white stem and a purple/ochre coloured cap, with a maximum diameter of 30 mm.[1] The gills will be white in younger fruiting bodies, but as the gills age they will become ochraceous.[1] This species is currently found in Scandinavia.
Merging of species
Russula cupreola and R. purpureofusca were merged under one name, Russula cupreola, in 2016.[1] The typing of R. purpureofusca was done with a juvenile specimen of R. cupreola, leading mycologists to believe it was a separate species.[1] After noticing similar features between the two species, researchers performed ITS1 sequencing and verified that the two species were conspecific.[1]
