Ophiocordyceps camponoti-balzani is a species of fungus that parasitizes insect hosts, in particular members of the order Hymenoptera.[1] It was first isolated from Viçosa, Minas Gerais (Atlantic Forest), on Camponotus balzani. This species was formerly thought to be Ophiocordyceps unilateralis, which has subsequently been divided into 4 species. O. camponoti-balzani infects ants, and later kills them after they move to an ideal location for the fungus to spread its spores. This has earned the species names such as “zombie fungus”, given the fungus has been observed to cause its hosts to bite hard into the substance it stands on, so that it can stably grow.[2]

Description

This species mycelium is a chocolate brown colour, and forms aggregations around the insects' joints, especially on legs and antennae. Its stromatal morphology is similar to O. camponoti-rufipedis, but its fertile region is dark brown when mature. Its ascomata are semi-erumpent and flask-shaped, measuring up to 200 millimetres (7.9 in), and possessing a pronounced neck.[1]

Its asci are 8-spored, hyaline and cylindrical, while its ascospores are multiserriate, thin-walled and rounded at their base.[1]
