DescriptionTraditional morphologically-based fungal species concepts have tended to go hand in-hand with a perception that fungal species are genetically 'firewalled' units between which almost no gene flow occurs. Also, prior to 1990, known examples of interspecific hybridization in fungi were very rare. However, observations on the internationally invading Dutch elm disease pathogens suggested that intense ecological disturbance events, including introductions or invasions, could result in hybridization. Since this could also lead to changes in a pathogen's aggressiveness, host range or other fitness attributes, it has considerable implications for the health of forests and natural ecosystems.
