Phlegmacium lavendulense is a species of fungus in the family Cortinariaceae.[1]
It was described in 1928 by John Burton Cleland who classified it as Cortinarius lavendulensis.
In 1960 it was reclassified as Phlegmacium lavendulense by Meinhard Michael Moser.
In 2022 a genomic study of the family Cortinariaceae transferred many Cortinarius species to new and existing genera. The basionym Cortinarius lavendulensis was transferred to Phlegmacium and listed in the paper as a novel combination accredited to the mycologists Tuula Niskanen and Kare Liimatainen.[2]
It is native to Australia and was described from a specimen collected in the Mount Lofty Ranges.
