These are a not uncommon sighting in (sub)tropical forest where bamboo is present. The fungus parasitizes white flies and scale insects which feed on the liquid-filled bamboo stalks. Once consumed by the fungus, the insect's mouth parts are used as a straw through which the same fluids are consumed by the growing fungus, segueing from entomopathogenicity to phytopathogenicity over the course of its life cycle. Genera belonging to this group include Ascopolyporus, Hypocrella and Moelleriella, and are generally poorly understood. See the Neglected Genera of Plant-, Fungal- and Insect-Associated Fungi species list for more examples.
