Exsudoporus permagnificus

Exsudoporus permagnificus is a species of bolete fungus in the family Boletaceae, native to Southern Europe and Western Asia (Cyprus and Israel).^[1][2] Described as new to science in 1981, the fungus was originally placed in genus Boletus.^[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.^[9][10][8] It forms ectomycorrhizal associations with oaks (Quercus), particularly Quercus suber, Quercus ilex, Quercus pubescens, Quercus alnifolia, Quercus calliprinos, Quercus pyrenaica and less often with sweet chestnut (Castanea sativa).^{[1][11][8][2]}
