Abstract
Morphology and phylogenetic analyses using the ITS and LSU regions of nrDNA were carried out on bolete collections belonging to Boletus s. str., originating from the Himalayan region of Pakistan. The phylogenetic analysis outlined the existence of previously unknown species of this genus. It is described here as Boletus himalayensis . Illustrations of the macroscopic characters and the microscopic features of the new species are provided. The distinction of B. himalayensis from allied species is discussed.
Highlights
The Himalayan region is considered a biodiversity-rich hotspot and an ecosystem of global importance
Many species have been described within Boletus s. str. based on morphological characters, but all these characters are mostly like typical of fleshy pored mushrooms and not unique to this group except a stalk with an enlarged base and a raised netted pattern at least over the uppermost portion, and a layer of tangled white hyphae that covers the immature tubes (Dentinger et al, 2010a); and the taxonomic and classification status of species within this group is confusing (Wang and Yao, 2005)
The literature showed that species in Boletus s. str. have a wide ecological range and a wide distribution
Summary
The Himalayan region is considered a biodiversity-rich hotspot and an ecosystem of global importance. Despite its importance, this region is one of the least studied in terms of the diversity of macrofungi (Mirjam, 2010). (Boletales, Boletaceae), which is considered polyphyletic (Nuhn et al, 2013). In this genus, all porcini (B. edulis and allies) form a group, Boletus s. Str., and the remaining species have instable state (Dentinger et al, 2010a). The literature showed that species in Boletus s. str. have a wide ecological range and a wide distribution
