Strain KNUF-MG-01 was isolated from a mango tree exhibiting witch’s broom symptoms in Gimhae-si and Gunwi-gun, South Korea. After 7 days of incubation on potato dextrose agar (PDA), the colonies displayed white to rose mycelia and reached dimensions of 79.6‒80.1 mm. Microconidia were abundant, mostly straight or slightly curved, non or one septate, measuring 4.6‒7.5‒13.9 × 2.0‒3.1‒6.4 μm. Macroconidia, characterized by being straight or slightly curved, slender, and 2 to 3 septate, measured 21.4‒36.7 × 3.5‒3.8 μm. Multilocus sequence analysis, using a combined dataset of internal transcribed spacer (ITS) regions, translation elongation factor-1α (TEF1-α), and β-tubulin (β-TUB) gene sequences, identified KNUF-MG-01 as a strain of Fusarium mangiferae. To our knowledge, this is the first report of F. mangiferae in Korea.
