Etymology:Rugi-“refers to the wrinkled pileus.


Diagnosis: This genus differs from all other genera of Boletaceae by its distinctively wrinkled and gelatinized pileus with yellow hymenophoral tubes, a stipe surface covered with distinctively dotted squamules, and an ixotrichodermium pileipellis.


Basidiomata stipitate-pileate with tubular hymenophore. Pileus hemispherical, convex or applanate, subtomentose, dry, strongly wrinkled (especially when young), usually with incurved or extended margin; context cream, light yellow to yellow, unchanging or staining light blue slowly when bruised. Hymenophore adnexed; hymenophoral surface light yellow, yellow, or brown, reddish brown to yellowish brown, unchanging or staining blue to dark blue quickly when bruised; pores nearly round to round; tubes grayish-yellowish, brownish yellow, unchanging or staining blue, dark blue to greenish blue quickly when bruised, adnate. Stipe central, light yellow to yellow, covered by minute squamules; context cream to light yellow, unchanging or staining light blue slowly when bruised; basal mycelia off-white to light yellow. Pileipellis an ixotrichodermium to an interwoven ixotrichodermium. Pleuro- and cheilocystidia subfusiform-ventricose. Basidiospores smooth, subfusiform, brownish yellow. Clamp connections absent.
