Villoboletus persicinus, gen. et sp. nov. (Boletaceae), a bolete with flocculent-covered stipe from northern China

ABSTRACT

Some collections from northern China are proposed as the new genus and species Villoboletus persicinus based on morphological assessments and molecular phylogenetic evidence. It is circumscribed by the pink pileus, white context turning pale blue to bule when exposed, yellow hymenophore surface turning blue when bruised, stipe covered with plenty of flocculent hairs, ellipsoid-fusiform to subfusiform smooth basidiospores, and the presence of hymenial cystidia. Phylogenetic analyses inferred from four gene fragments (28S, tef1, rpb1, and rpb2) revealed a distinct position of this new genus in Boletaceae, but no place to accommodate it at subfamily rank.
