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 ).
