Exsudoporus is a genus of fungi in the family Boletaceae. It was circumscribed in 2014 by Alfredo Vizzini and colleagues,[1] following a number of molecular studies that outlined a new phylogenetic framework for Boletaceae and revealed the genus Boletus in its traditional circumscription to be polyphyletic.[2][3] However, due to lack of sufficient sequences, Wu and colleagues (2016) were reluctant to accept the newly proposed genus and considered it a synonym of Butyriboletus.[4] Following additional phylogenetic sequencing and morphological analyses, Loizides and colleagues confirmed the monophyly of Exsudoporus and reinstated the genus in 2019.[5]

Species of Exsudoporus are united by the tendency of their pores to exude yellowish droplets, hence the generic epithet.[1] Other distinctive features separating Exsudoporus from its sister-genus Butyriboletus, include the reddish-orange colour of their pores and the distinctly elongated, often 'sculpted' (raised) reticulation on the stipe.[5]

The genus currently accommodates three species, of which one (Exsudoporus permagnificus) is native to Europe, and two (Exsudoporus floridanus, Exsudoporus frostii) are native to North America.[1]
