Fusarium commune Skovgaard, O'Donnell & Nirenberg (2003)

This fungus is widely distributed in temperate and subtropical climates, causing root rot, basal stem rot and stunting on various crops and trees. On PDA, it produces white, densely floccose to fluffy colonies with the reverse being grayish yellow with a magenta to dull violet pigmentation under the surface. Chlamydospores are formed singly or in pairs. Macroconidia are typically 3-septate, about 30-40 x 4-6 µm in size and slightly curved. Microconidia are usually aseptate, 7-14 x 3-4 µm large, straight to slightly curved. The fungus occasionally produces polyphialides in contrast to the Fusarium oxysporum species complex.
