Tolypoalbin, a new tetramic acid from Tolypocladium album TAMA 479
Many of the species in the order Hypocreales (Ascomycota, Sordariomycetes) are known to be associated with other organisms such as plants, insects and fungi as pathogens, saprobes or symbionts.1 Recent multigene phylogenetic analyses inferred that the ancestral hypocrealean fungi mainly had taken plant-based nutrients1,2 and the species diversity was expanded in association with the host range expansion from plants/debris to animals, insects and fungi.3
