Abstract:

Boletus sinopulverulentus, a new species discovered in Shaanxi Province (central China), is formally described and illustrated. A detailed morphological description is provided and accompanied by line-drawings of the main anatomical features, a colour illustration of fresh material in habitat and the pertinent supporting molecular data (ITS sequences analysis). Boletus sinopulverulentus belongs to the B. pulverulentus species complex. The diagnostic traits of the species allied to the new taxon are also discussed for comparison. Finally, based on molecular analysis the taxonomy of Boletus and Xerocomus is briefly discussed.
