Boletinellaceae

Boletinellaceae are a small family of mushroom-forming fungi, primarily characterized by small pores on the underside of the cap rather than gills. Though in the order Boletales, research shows they and Gyroporaceae are more closely related to earthballs of Sclerodermataceae than Boletaceae.
Genera include "Boletinellus" and "Phlebopus", the latter genus showing some Gondwanan distribution found in Australia, Sri Lanka and elsewhere. It contains the gigantic "Phlebopus marginatus", the cap of which can reach 1 metre in diameter.
