Baorangia G. Wu & Zhu L., in Wu et al., Fungal Divers 81(1):124 (2016)

 

Etymology:Baoand rangmean thinand hymeniumin Chinese, respectively, referring to the thin hymenophore.

 

Diagnosis: This genus differs from all other genera of Boletaceae by its thin hymenophore (thickness of hymenophore 1/31/5 times that of pileal context at the position halfway to the pileus center) with yellow tubes and pores which stain blue when bruised, a light yellow context which stains pale blue slowly when cut, and a trichodermium to an interwoven trichodermium pileipellis.

 

Basidiomata stipitate-pileate with tubular hymenophore. Pileus hemispherical, convex or applanate, subtomentose, dry, usually incurved at the margin when young; context pale yellow to yellow, slowly staining pale blue when cut. Hymenophore relatively thin (thickness of hymenophore 1/31/5 times that of pileal context at the position halfway to the pileus center), usually decurrent; hymenophoral surface and tubes yellow, immediately staining light blue to greenish blue when injured; pores angular, or sometimes nearly round; tubes short. Stipe smooth or occasionally with reticulations at the upper part; context pale yellow to yellow, staining pale blue; basal mycelia white to pale yellow. Pileipellis a trichodermium to an interwoven trichodermium. Pleuro- and cheilocystidia present. Basidiospores smooth, subfusiform to elongated subfusiform, light yellow to brownish-yellowish. Clamp connections absent.
