本文报道牛肝菌属一新种,属于牛肝菌组和短管牛肝菌亚组(新亚组)。
A new taxon of Genus Boletus collected from Southern Yunnan,it is described as Boletus brevitubus Zang to be placed in Sect.Boletus,Subsection Brevitubi Zang nov.subsect.It is a clear difference in darkish colour when the spe- cimens are fresh and the hymenium by its slightly shortest and smaller tubes (0.2— 4.5mm long),pores simple minute (12—18 per mm.),and the basidiospores are remarkable for their roundish to ellipsoid,which distinguish it immediately from all other taxa treated in any subsections in Sect.Boletus.The morphology of basidi- ospores although looked similar to the genus Gyroporus,yet the stipe is typically solid,reticulate,freshy and thickened,never hollow,context always yellow,but not whitish,hymenophore always adnate or decurrent never depressed to free or nearly so,which at least for the present is being recognized as a new subsection and a new taxon.This new species has been collected fruiting solitarily under Cephalocitrus grandis (Obs.) Tseng and Delonix regia (Bojer) Rafin.in tropical area,but the mycorrhizal association and affinities of this fungus are not known.
