Data from: Pseudobaorangia (Boletaceae, Boletales), a new genus for Boletus lakhanpalii

Boletus specimens collected from Baima Snow Mountain Nature Reserve, Yunnan Province, have been identified as Pseudobaorangia lakhanpalii based on morphological and phylogenetic analyses. According to ITS sequence data, our collections exhibit the nearest homologous affinity to Boletus lakhanpalii, sharing a striking similarity of 99.53% (KEF13271, 639 bp) and 99.44% (KEF13272, 539 bp). However, due to limited data and complex developmental relationships, the phylogenetic position of this species could not be clearly determined. This study conducted a phylogenetic analysis by combining nrLSU, RPB2, and TEF1-α genes, and the results showed that this species has a close phylogenetic relationship with Baorangia, sharing some morphological characteristics, but also highlights several differences. Therefore, a new genus Pseudobaorangia is proposed with P. lakhanpalii as the type species, and its detailed description is provided.
