Hemileccinum
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 |
