Lanmaoa

Lanmaoa G.Wu, Zhu L. Yang, Halling, in Wu et al., Fungal Diversity 81(1): 1–24 (2015)

 

Etymology: Lanmaoa is named for Mr. Lan Mao (1397– 1476, Ming Dynasty), an ancient Chinese botanist, who used the Chinese name “niuganjun” (cattle liver fungus) for boletes in the Chinese literature for the first time.

 

Diagnosis: This genus differs from all other genera of Boletaceae by its thin hymenophore (thickness of hymenophore 1/3–1/5 times that of pileal context at the position halfway to the pileus center) which stains blue when bruised, a light yellow context which stains pale blue slowly when cut, and an interwoven trichodermium to a subcutis pileipellis.

 

Basidiomata stipitate-pileate with tubular hymenophore. Pileus hemispherical, convex or applanate, subtomentose, dry, slightly incurved at themargin when young; context off-white to cream yellow, slowly  staining pale blue to light blue when injured. Hymenophore adnexed or sinuate, thickness of hymenophore 1/3–1/5 times that of pileal context at the position halfway to the pileus center; hymenophoral surface cream yellow to lemon yellow, staining dull blue when injured; pores angular or nearly round; tubes concolorous with hymenophoral surface or light red, staining dark blue when injured. Stipe central, cream yellow, light yellow to lemon yellow at the apex and light to dark purple red towards the base; Basal mycelia yellowish white to white. Pileipellis often an interwoven trichodermium to subcutis, rarely ixosubcutis. Pleuro- and cheilocystidia subfusiform-ventricose or clavate. Basidiospores smooth, narrowly suboblong to subfusoid, light yellow to brownish yellow. Clamp connections absent.
