Hemileccinum is a genus of fungi in the family Boletaceae. It was erected in 2008 by Josef Šutara to contain two species united by a number of shared morphological features: H. depilatum and the type H. impolitum.[1] In 2014, Wu et al. found it to be distinct from other bolete genera in a molecular phylogenetic study and found it to be most closely related to Corneroboletus.[2] In 2015, H. subglabripes was transferred to Hemileccinum from Boletus based on DNA evidence,[3] while subsequent studies further confirmed the monophyly of the genus.[4]

Morphological features of xerocomoid boletes[1][5][6]

Boletus s.str. Hemileccinum Xerocomellus Xerocomus s.str.
Spore surface Smooth Smooth Longitudinally striated or smooth, never bacilate Bacilate
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
