Allocordyceps is an extinct genus of parasitic fungus in the order Hypocreales that parasitized carpenter ants.[1][2] The fossil of Allocordyceps baltica, from the Baltic Amber, represents the oldest known fossil of an ant-parasitizing fungus before Ophiocordyceps.[3][4]

Description

edit

Allocordyceps is characterized by its ascoma being an orange color, stalked and cusp shaped. It also has a pair of partially immersed perithecia that emerges from the rectum. Hosts parasitized by Allocordyceps have separate stromata with separate mycelium emerging from the neck and abdomen.[4] It might alter its host's behavior much like the extant Ophiocordyceps unilateralis.
