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).[1] 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.[2][3][4]
Most members of Xerocomus are edible.
Ladurner and Simonini published a monograph on Xerocomus in 2003.[5] In 2008, Hills included 18 species found in Britain, not including some species sometimes treated as Xerocomus, including Boletus pulverulentus and Boletus impolitus.[6]
Molecular phylogenetic studies strongly imply that Xerocomus is a heterogeneous genus of polyphyletic origin.[7]

Description
Morphological features of xerocomoid boletes[18][19][1]
| Boletus s.str. | Hemileccinum | Xerocomellus | Xerocomus s.str. | |
|---|---|---|---|---|
| Spore Surface | Smooth | Smooth | Longitudinally striated or smooth, never bacillate | Bacillate |
| Hymenophoral trama | Boletoid type with gelatinous lateral strata | Boletoid type with gelatinous lateral strata | Intermediate between boletoid and phylloporoid when fully developed with distinct but weakly gelatinous lateral strata | Phylloporoid type with nongelatinous lateral strata |
| Pileipellis | Trichoderm, sometimes collapsing, rarely ixotrichoderm or other | Initially trichoderm but collapses with age | Initially palisadoderm, typically encrusted | Initially a trichoderm, never encrusted |
| Lateral stipe stratum | Frequently gelatinous, 60-90 μM thick, thicker than that of Xerocomellus | Similar to that of Leccinum species, ornamented with stipe scabrousities up to 400-640 μM thick | Frequently not present, reduced to no more than 30-40 μM thick, not gelatinous | Lateral stipe stratum never gelatinous and 80-200 μM thick |
