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]

Hymenophoral tramaBoletoid type with gelatinous lateral strataBoletoid type with gelatinous lateral strataIntermediate between boletoid and phylloporoid when fully developed with distinct but weakly gelatinous lateral strataPhylloporoid type with nongelatinous lateral strata

Lateral stipe stratumFrequently gelatinous, 60-90 μM thick, thicker than that of XerocomellusSimilar to that of Leccinum species, ornamented with stipe scabrousities up to 400-640 μM thickFrequently not present, reduced to no more than 30-40 μM thick, not gelatinousLateral stipe stratum never gelatinous and 80-200 μM thick
