Interpretive Summary: Fungi are used in the biological control of plant pathogens. Accurate systematic knowledge of the fungi used in biological control is essential to the effective use of these agents. However, for many species of microfungi such knowledge is lacking particularly the generic placement of the sexual and asexual states. The sexual and asexual state of hypocrealean biocontrol fungi have been studied and are classified in the genus Bionectria. This classification more closely reflects their evolutionary relationships. This work is useful to those who are seeking to discover and develop fungi as biological control agents of plant pathogens.

Technical Abstract: Nectria as it is traditionally viewed is heterogeneous. Species of the Nectria ochroleuca group differ significantly from Nectria sensu stricto, particularly from the type species Nectria cinnabarina, but they are similar to Bionectria tonduzii, the type species of Bionectria. To reflect natural relationships in the generic classification, N. ochroleuca, N. brassicola, N. aureofulva, and N. apocyni are transferred to Bionectria.
