Swiss needle cast (SNC) and its causal organism, Phaeocryptopus gaeumannii, were first detected in New Zealand in 1959 on the North Island near Taupo. Approximately 10 years later, the disease made its first appearance on the South Island (Kimberley et al. 2011). While the environmental factors influencing SNC severity in New Zealand have been well studied (Hood and Kimberley 2005, Stone et al. 2007, Watt et al. 2010, Watt et al. 2011), this study represents the first assessment of population genetic structure and diversity for introduced populations of P. gaeumannii.
