Amoenoboletus brachysporus (Boletaceae), a new species from Southern China

Amoenoboletus brachysporus is described as a new species from Southern China. Morphologically, it is closely related to A. granulopunctatus and A. mcrobbii, but distinguished by its relatively larger basidiomata with the pileus covered with conspicuous greyish yellow to yellowish brown patches or coarse fibrillose squamules, longer and broader stipes densely covered with dark red, appressed squamules, and obviously shorter basidiospores (7-9 x 5-6.3 mu m). Phylogenetically, newly generated sequences from the new species form a distinct clade within the genus Amoenoboletus. Detailed morphological descriptions, colour photographs of the new species and comparisons with closely related taxa are presented.
