Teratosphaeria gauchensis (M.-N. Cortinas, Crous & M.J. Wingf.) M.J. Wingf. & Crous 2009
This fungus causes stem canker of eucalypts like several other species of Teratosphaeria. It has been reported from Africa, Europe, South America and Hawaii. New infections typically start in spring as 2-5 mm necrotic lesions on young parts of the stems. The lesions enlarge to cankers filled with gum, resulting in cracks and malformations. Severe infections girdle the stems, epicormic shoots develop and the tops of the trees die.
Synonyms:
Colletogloeopsis gauchensis
Kirramyces gauchensis
