Notes: Both fungus and host plants are introduced; Birch (1935) stated that this fungus
attacked stems of wounded trees one to ten years old, particularly after late frost
injury. He noted that it destroyed many thousands of acres of Pinus radiata planted
in unfavourable sites in 1925-35. Gilmour (1966a) noted that it is still common and
widespread in its occurence in New Zealand pine forests.
