Abstract

The new genus Cyanonectria is proposed for Nectria cyanostoma (≡ Cyanonectria cyanostoma comb. nov.). This genus is characterized by Nectria-like, red perithecia that have a bluish-purple papilla and a Fusarium anamorph. DNA sequences (large subunit and internal transcribed spacers of the nuclear rDNA) indicate that C. cyanostoma is not closely related to Nectria sensu stricto. In addition, the phylogenetic data also show that the closest relatives for Cyanonectria also have Fusarium anamorphs.
