Borofutus Hosen & Zhu L. Yang, in Hosen et al., Fungal Diversity 58: 219 (2012)
Etymology: Borofutus is from Bengali language, where ‘boro’ means large and ‘futo’ means pore, referring to the broad pores of the hymenophore.
Basidiomata epigeous, stipitate-pileate with tubular hymenophore. Pileus covered with squamules. Hymenophore subdecurrent, broadly tubular; pores up to 2–6 mm wide, pallid to cream when young, becoming yellowish to golden brown at maturity. Stipe central, covered with squamules but apical part glabrous, upper half ribbed by the subdecurrent lines of the hymenophore or confined to apex; basal mycelium whitish. Context pallid to light yellowish, usually unchanging in color when cut but turning pale reddish to pale reddish purple in some areas over the course of 1–2 h. Basidiospores purple to purplish red in H2O, purplish violet in 5 % KOH, boletoid to somewhat amygdaliform, slightly thick-walled; minutely verrucose under light microscope but with regular to irregular shallow pits under SEM. Cheilocystidia and pleurocystidia lageniform, thick-walled. Pileipellis a trichoderm, becoming a subcutis when mature. Clamp connections absent.
