Specialized Fungal Parasites and Opportunistic Fungi in Gardens of Attine Ants
Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012 Ants in the tribe Attini (Hymenoptera: Formicidae) comprise about 230 described species that share the same characteristic: all coevolved in an ancient mutualism with basidiomycetous fungi cultivated for food. In this paper we focused on fungi other than the mutualistic cultivar and their roles in the attine ant symbiosis.
