Alessioporus和Pulchroboletus被认为是适应欧洲嗜热-干旱种Xerocomus ichnusanus和X. roseoalbidus分别。本研究重点关注形态特征和多基因分子系统发育（nrITS、nrLSU、tef-1 alpha数据集），以阐明这两种罕见的地中海牛肝菌的分类地位，并描绘牛肝菌科内的自然分类。宏观和微观描述的两个种的基础上包括分类单元采样提供和支持的线条画的主要解剖特征。系统发育关系，生态学，地理分布和最密切相关的类群的划界也被强调。此外，还为两种植物选择了表型标本。
Alessioporus and Pulchroboletus are proposed as new monotypic genera to accommodate the thermo-xerophilic European species Xerocomus ichnusanus and X. roseoalbidus respectively. The present research focused on both morphological features and multigene molecular phylogeny (nrITS, nrLSU, tef-1 alpha datasets) to elucidate the taxonomic status of these two rare Mediterranean boletes and delineate a natural classification within the family Boletaceae. Macro- and microscopic descriptions of the two species based on inclusive taxon sampling are provided and supported by line drawings of the main anatomical features. Phylogenetic relationships, ecology, geographical distribution and delimitation from the most closely allied taxa also are highlighted. In addition, epitype specimens are selected for both species.
