7216A3D906265C23849410990CF60FDF.taxon	discussion	Discussion. Gyroporus brunneofloccosus, originally described from southern China, is characterised by the initially dark brown to brown and then brown to light red-brown pileus with concolorous floccose-scaly to coarsely tomentose squamules, the extended pileal margin, the white pileal context staining cerulean blue or greenish-blue to dark blue or deep blue when bruised, the initially yellowish to pale yellow and then greenish-yellow hymenophore staining cerulean blue to greenish-blue when bruised, the brownish to brown or light red-brown stipe, the spongy and then hollow context in the stipe, the frequent clamp connections in all tissues, the ellipsoid basidiospores and the distribution in tropical forests dominated by plants of the families Fagaceae and Pinaceae (Li et al. 2003). In China, G. brunneofloccosus was misidentified as G. cyanescens by Bi et al. (1990, 1994), Ying and Zang (1994) and Mao (2000). However, these two species can be separated both by phylogenetic and morphological evidence. Our phylogenetic analysis of atp 6 data (Fig. 1) indicates that G. brunneofloccosus is closely related to G. phaeocyanescens. However, G. phaeocyanescens, originally described from Belize by Singer et al. (1983), has fulvous to snuff brown pileus and relatively large basidiospores measuring 9.3 - 14.7 x 5.3 - 6.7 µm (Singer et al. 1983; Li et al. 2003).	en	Huang, Cong, Zhang, Ming, Wu, Xing-Liang, Wu, Gang, Xu, Jian-Ping, Yang, Zhu L., Li, Yan-Chun (2021): Cyanescent Gyroporus (Gyroporaceae, Boletales) from China.
