Phlebopus marginatus, known as the salmon gum mushroom in Western Australia, is a member of the Boletales or pored fungi and possibly Australia's largest terrestrial mushroom with the weight of one specimen from Victoria recorded at 29 kg (64 pounds). It is an imposing sight in forests of southeastern and southwestern Australia. Initially described as Boletus marginatus in 1845, and also previously known by scientific names such as Phaeogyroporus portentosus and Boletus portentosus it is in fact not as closely related to typical boletes as previously thought.
English naturalist Miles Joseph Berkeley initially described Boletus marginatus in 1845, from the writings and specimens of James Drummond, from the vicinity of the Swan River Colony in Western Australia. Berkeley and Broome described Boletus portentosus in a report published in 1873 of the fungi of Ceylon, from a specimen with a 25 cm (8 in) diameter cap collected on June 15, 1869. They held it to be related to Boletus aestivalis. Microscopic differences led to it being reclassified; Boedijn noted the shape of its spores, lack of cystidia and short tubes and allocated it to the genus Phlebopus in 1951. New Zealand botanist Robert McNabb followed Rolf Singer who had determined Phlebopus was a nomen dubium (though conceding Singer was likely in error), and coined the binomial Phaeogyroporus portentosus, by which it was known for some years. In his 1982 review of the genus, mycologist Paul Heinemann used this latter designation. The generic name is derived from the Greek Φλεψ/Φλεβο- "vein", and πους "foot".
