ABSTRACT: A new taxon Sinoboletus wangii is proposed in the family Boletaceae. It is characterized by the tomentose
pileus, stipes subclavate, and fine ridges striate, but not reticulated and the basidiospores are usually small, less than 6 um
long, sometimes reaching about 16 µm long. It is mycorrhizal fungus associated with family Fagaceae. This species is
dedicated to a distinguished Chinese mycologist Prof. Dr. Yun - Chang ( Wei - Qing ) Wang on the occasion of his 100th
birthday and his glorious 75th anniversary of following upon a mycological career.

bright yellow to golden - yellow, adnate to sinuate – adnate, decurrent. Tubes compound, produced in
two definite layers, superior 0.1 – 0.3 mm long, 0.1 – 0.2 mm diam, inferior 2 – 4 mm long, 0. 2 – 0.4
mm diam, angularis or irregularly angularis, 9 – 11 pores per cm. Stipes 3 – 5 × 0.2 – 0.3 cm, clavate
to equal, ruby - red apically , not reticulate but striate, at the base bulbous, whitish. Basidiospores
variable, 6 – 16 × 4 – 6 µm, ellipsoid, smooth, hyaline to pale yellow. Basidia obclavate or broadly-
elliptic , 15 – 20 × 9 - 12 µm. Pleurocystidia clavate 7 – 12 × 20 – 40 µm, mamillate. Cheilocystidia
fusiform 20 – 45 ×7 - 16 µm. Tube trama provided with parallel veins.
Commentary: Sinoboletus wangii is characterized by the reddish pileus and variable-sized
basidiospores, and differs from Sinoboletus tengii M. Zang et Y. Liu (2002). The pleurocystidia often
occurs mamillate elements on the surface. It is easily separated from the other relative taxa in the genus
Sinoboletus ( Zang, Li & Petersen, 2001).
