Exsudoporus permagnificus is a species of bolete fungus in the family Boletaceae, native to Southern Europe and Western Asia (Cyprus and Israel).

[3] Following molecular studies outlining a new phylogenetic framework for Boletaceae,[4][5] the fungus was transferred to the newly erected genus Exsudoporus in 2014, to which it is the type species.

[6] Nevertheless, Wu and colleagues (2016) were reluctant to accept the newly proposed genus due to a lack of sufficient sequences and regarded it a synonym of Butyriboletus.

[7] Following studies reinstated the status of Exsudoporus as a monophyletic genus sister to Butyriboletus, following additional collections and extended phylogenetic and morphological analyses.

[8][2] Exsudoporus permagnificus is rare throughout its distribution area and listed as a vulnerable or endangered species in a number of regional and national checklists.
