Cyanescent (Gyroporaceae, Boletales) from China.

species with cyanescent oxidation reactions were investigated, based on morphology and phylogenetic analysis of DNA sequences from the nuclear ribosomal large subunit (nrLSU), the nuclear ribosomal internal transcribed spacer (ITS) and the mitochondrial adenosine triphosphate ATP synthase subunit 6 (). Three species, including two new species, namely and and one previously-described species, namely , are revealed from China. Collections formerly reported from China as "" are either or . The new species are documented and illustrated in detail, while the concept of is refined with additional recently-collected materials. Additionally, the cyanescent species , previously described from China, is shown to be a member of the genus , based on re-examination of the type specimen. A key to the cyanescent species from China is provided.
