Botryosphaeria tsugae n. sp. was found to have a Macrophoma conidial state. The fungus causes cankers and dieback of branches and leaders of Tsuga heterophylla (Raf.) Sarg. in the coastal forests of British Columbia. The fungus attacks the cambium, kills meristematic cells, and causes the collapse of the phloem.
