''Xerocomus'' is a genus of fungi that is related to ''Boletus''. Many mycologists do not recognize the distinction; however, several molecular studies have demonstrated that they are two distinct genera, with clear morphological differences. The genus ''Xerocomus'' has been further divided into ''Xerocomellus'' and ''Hemileccinum'' by Šutara (2008).〔 The members of the ''Xerocomellus'' genus are more closely related to ''Boletus'' than true ''Xerocomus'' is, which is relatively distantly related to ''Boletus'' and more closely related to ''Phylloporus''. Other former ''Xerocomus'' species have been moved to ''Aureoboletus'', ''Imleria'', ''Hortiboletus'' and ''Rheubarbariboletus''.〔〔〔 Most members of ''Xerocomus'' are edible. Ladurner and Simonini published a monograph on ''Xerocomus'' in 2003.〔 In 2008, Hills included 18 species found in Britain, not including some species sometimes treated as ''Xerocomus'', including ''Boletus pulverulentus'' and ''Boletus impolitus''.〔 Molecular phylogenetic studies strongly imply that ''Xerocomus'' is a heterogeneous genus of polyphyletic origin.〔 ==Species== *''X. belizensis'' - Belize〔 *''X. chrysonemus'' *''X. communis'' *''X. cyaneibrunnescens'' – Guyana〔 *''X. ferrugineus'' *''X. griseo-olivaceus'' – New Zealand〔 *''X. guidonis'' *''X. illudens'' - North America, India and Bangladesh〔〔〔 *''X. lentistipitatus'' – New Zealand〔 *''X. mcrobbii'' – New Zealand〔 *''X. nothofagi'' – New Zealand〔 *''X. olivaceus'' - Belize〔 *''X. parvogracilis'' – Guyana〔 *''X. porophyllus'' – China〔 *''X. potaroensis'' – Guyana〔 *''X. rufostipitatus'' – New Zealand〔 *''X. silwoodensis'' (edibility not known, found in England, Spain, and Italy.
