The ascomycete fungus Phaeocryptopus gaeumannii is the causal organism of Swiss needle cast (SNC), a foliage disease of Douglas-fir (Pseudotsuga menziesii). The disease was first described in forest plantations in Europe in the 1920s (Boyce 1940). It has since been determined that P. gaeumannii is…

Swiss needle cast (SNC), a foliage disease of Douglas-fir (Pseudotsuga menziesii), is caused by the physical blockage of the stomata by pseudothecial ascocarps of the fungus Phaeocryptopus gaeumannii. Occlusion of the stomata results in a decrease in the ability of the host to exchange gases with…

Swiss needle cast (SNC) is a Douglas-fir foliage disease caused by the fungus Phaeocryptopus gaeumannii Rohde (Petrak). The spore-bearing structures of this fungus (pseudothecia) occlude the stomata in Douglas-fir needles resulting in an inhibition of gas exchange and photosynthesis, premature…

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…
