Tengioboletus G. Wu & Zhu L. Yang, in Wu et al., Fungal Diversity 81: 100 (2016)
Etymology: ‘‘Tengioboletus’’ named after the late Prof. S.C. Teng, a mycologist who made great contributions to the study of Chinese fungi.
Diagnosis: This genus differs from all other genera of Boletaceae in its white to yellow hymenophore, yellowish to yellow context without color change when cut, an epithelium to ixotrichodermium pileipellis composed of inflated hyphae, and smooth basidiospores.
Basidioma stipitate-pileate with tubular hymenophore. Pileus convex or applanate, glabrous to subtomentose, dry, sometimes viscid when wet; context yellowish to yellow, color unchanging when cut. Hymenophore adnate to sinuate; hymenophoral surface white when young, yellowish to yellow when mature, color unchanging when injured; pores roundish; tubes concolorous with hymenophoral surface, color unchanging when injured. Stipe central, yellow, orange-yellow to brownish yellow, glabrous or reticulate; basal mycelium light yellow. Pleuro- and cheilocystidia subfusiform-ventricose or clavate, with subacute apex or long beak. Pileipellis an epithelium to an ixotrichodermium composed of distinctly inflated or cystidioid terminal cells. Basidiospores smooth, subfusiform, brownish yellow. Clamp connections absent.
