Abstract:
Embellisia allii causing bulb canker of white garlic (Allium sativum) has been observed on harvested or stored garlic bulbs. Identification of the fungus was determined based on the symptoms and morphological characteristics on in vitro potato dextrose agar (PDA) and malt extract agar (MEA). Colonies were effuse, blackish brown to black, velvety or powdery. Conidia were solitary, almost straight, most commonly ellipsoidal (or subcylindrical) to ovoid, mid to dark brown, smooth, with very dark 1 to 6 transverse (commonly 3~4) and occasionally 1 or 2 oblique or longitudinal septa, and 30.4x13.4 microm (av.). Conidiophores were simple or branched, straight or flexuous, up to 80 microm long and 5.1~10.2 microm thick. Chlamydospores were developed through enlargement and repeated cellular division of several adjacent hyphal cells to form a complex of thick-walled cells. The conidial measurements of garlic isolates closely matched the previous description of E. allii.
