Crocinoboletus

Crocinoboletus is a fungal genus in the family Boletaceae. Circumscribed in 2014, it contains two species: Crocinoboletus laetissimus, and the type, C. rufoaureus. This latter bolete was originally described by George Edward Massee in 1909 from collections made in Singapore. 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 in the middle part of the cap, and a cutis at the cap margin. The intense orange color of the fruitbodies is caused by boletocrocin pigments.
