Description:
Diagnosis: Basidiomata stipitate-pileate. Pileus hemispherical, convex or applanate, subtomentose, dry, strongly wrinkled (especially when young), usually with incurved or extended margin. Context cream, light yellow to yellow, unchanging or staining light blue slowly when bruised. Hymenophore adnexed to adnate, light yellow, yellow, or brown, reddish brown to yellowish brown, unchanging or staining blue to dark blue quickly when bruised, with tubes grayish-yellowish, brownish yellow, unchanging or staining blue, dark blue to greenish blue quickly when bruised, with pores nearly round to round. Stipe central, light yellow to yellow, covered by minute squamules, with basal mycelia off-white to light yellow. Pileipellis an ixotrichodermium to an interwoven ixotrichodermium. Hymenial cystidia present. Spores smooth, subfusiform, brownish yellow. Clamp connections absent.
Registration number: MB 810352
Type species: Krombholzia extremiorientalis Lj.N. Vassiljeva, Notul. syst. Sect. cryptog. Inst. bot. Acad. Sci. U.S.S.R. 6: 191. 1950.
Ectomycorrhiza: Presumed with Pinaceae, Fagaceae.
Distribution: Eastern Asia (China, Japan, far east Russia, Korea, Nepal, Thailand); Central and South America (Costa Rica, Colombia)
Commentary: This genus proposed to recognize Clade 47 of Wu et al. (2014) based on phylogenetic inference.
