Neoboletus was segregated from Boletus and typified with Neoboletus luridiformis based on morphological and molecular phylogenetic data (Vizzini 2014). This genus contains 18 species, and the molecular data of most species are available. Many members of Neoboletus or other genera in Boletaceae are interesting and important for their mycorrhizal relationships with trees, which are widely distributed in boreal forests from Europe and Asia to North America, with edibility, medicinal value, and toxicity (Chai et al. 2019, Gelardi et al. 2019). The genus is characterized by basidiomata that are either stipitate-pileate or sequestrate; when basidiomata stipitate-pileate, the pores are brown, dark brown to reddish brown when young, and turning yellow when old. The tubes are often yellow, and the hymenophore and context exhibit blue staining. The stipe is typically adorned by punctuation (Vizzini 2014, Chai et al. 2019).
