Taxonomy

Chinese mycologist Mu Zang, who circumscribed the genus in 1992 with Sinoboletus duplicatoporus as the type species,[1] has been a coauthor on every subsequent described species. The genus name refers to the affiliation with Boletus, and its Chinese distribution. Zang considered the genus to be similar to Boletus or Xerocomus, but suggested that the unique stratified pore arrangement precluded placement in either of these genera.[1]

Description

Sinoboletus species produce caps that range in shape from hemispheric, to convex, to flattened. The cap surface is dry, with a tomentose texture. The flesh of the cap is either thin or thick. The golden yellow to yellow pore surface features crossveins that are arranged in two distinct layers. The pores, initially round, become angular or irregular in age. The club-shaped stipes have a dry surface, with striations at the top but no reticulations. Spores have an ovoid to ellipsoid shape.[1]

Habitat and distribution

Sinoboletus species are suspected to be mycorrhizal with members of the families Fagaceae and Pinaceae, particularly Castanea calathiformis, and Castanea fleuryi.[1]
