Fusarium strains in the Gibberella fujikuroi species complex cause diseases in a number of economically important plants. DNA sequencing data reveals the presence of two major groups representing cryptic species in F. subglutinans. These were further divided into groups that appeared to be reproductively isolated in the environment which suggests that they are undergoing separation into distinct taxa. One such divergent group is Fusarium subglutinans f. sp. pini which causes pitch canker of pine trees.Fusarium subglutinans f. sp. pini Represents a Distinct Mating Population in the Gibberella fujikuroi Species Complexdagger It is a synonym of Fusarium circinatum.
