Taxonomy

Chinese mycologist Mu Zang, who circumscribed the genus in 1992 with ''Sinoboletus duplicatoporus'' as the

type species In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the spe ...

, 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.

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 In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plant ...
