 Description: On PDA, growth is rapid, with delicate, white to pink or pale purple, aerial mycelium. Orange sporodochia and dark blue sclerotia are present or absent. Colonies reach 4.6-5.0 cm diameter for 4 days at 24℃. From below the cultures are colorless to dark purple in color. Microconidia formed abundantly in long chains and in false heads from elongated unbranched or branched monophialides, 1-celled, oval to club-shaped with a flattened base, 5.0 –12.5 × 2.5– 4.5 μm. Macroconidia are rare in some isolates. They produced from monophialides, falcate, slender, thin-walled, with an elongated curved apical cell and pedicellate basal cell, mostly 3-5 septate, 31.3–58.8 × 3.0– 4.5 μm. Chlamydospores are absent. Gibberella fujikuroi (Sawada) Ito et Kimura is heterothallic and the teleomorphs can be found on diseased rice plants on June during rainy weather in Taiwan and can also be obtained by pairing compatible monoconidial isolates on Sach’s agar media supporting sterilized rice straw. Perithecia are globose, dark blue in color, measuring 283 × 247 μm (average). Asci are ellipsoid to clavate. Ascospores are hyaline, ellipsoid, mostly 1 or 2 septate, some are 3 septate, constricted at septum, measuring 17.9 × 6.24 μm.
