Abstract
Ceratocystis fimbriata is being considered as one of the contributing factors in case of mango decline. It is a widely distributed; plant pathogenic fungus which causes wilt and canker on many woody hosts. Recently C. fimbriata was reported in Mango Decline from Oman and now it has been for the first time isolated from declining mango trees from Sindh, Pakistan. Morphological characteristics show perithecia brown to black with globose base, necks almost 800-900 µm long with ostiolar hyphae. Ascospores elliptical 4-8 x 2-5 µm, hyaline, non septate, hat shaped appearance. Conidiophores hyaline, septate upto 150 µm long. Conidia cylindrical, sometimes in chains, truncate at the ends.
