Crocinoboletus is a fungal genus in the family Boletaceae. Circumscribed in 2014, it contains two species: Crocinoboletus laetissimus, and the type, C. rufoaureus.^[1] This latter bolete was originally described by George Edward Massee in 1909 from collections made in Singapore.^[2] The genus is readily characterized by bright orange fruitbodies that readily stain blue-olive when injured, and smooth spores. The cap cuticle is made of a trichoderm (a cellular arrangement wherein the outermost hyphae emerge roughly parallel, like hairs, perpendicular to the cap surface) in the middle part of the cap, and a cutis (where hyphae run parallel to the cap surface) at the cap margin. The intense orange color of the fruitbodies is caused by boletocrocin pigments.^[1]
