摘要: Severe defoliation of Scots pine by the gall midge Cecidomyia baeri associated with fungus Sclerophoma pithyophila is described. Culture work supported Robak’s view that a form Pullularia pullulans stage Sclerophoma. Phoma acicola, quoted several authorities as synonymous pithyophila, occurs under different pathological circumstances from and probably less important.
