Two new species of Boletopsis (Bankeraceae, Thelephorales) from Southwest China.

ABSTRACT: Two new species of Boletopsis, B.macrocarpa and B.tibetana, are described and illustrated from Southwest (SW) China based on morphology, ecology and phylogenetic analyses by the internal transcribed spacer regions (ITS) and the large subunit of nuclear ribosomal RNA gene (nLSU). Boletopsismacrocarpa is characterized by big basidiocarps (up to 18 cm in diam), guttulate basidiospores, and the presence of gloeoplerous hyphae in context and growing in pure forest of Pinusyunnanensis. Boletopsistibetana is characterized by smaller pores (3-4 per mm), the presence of gloeoplerous hyphae in pileipellis, and the growth in forests of Picea. Phylogenetically, the two new species are grouped in two independent lineages nested in Boletopsis. In a
