Typical fast growing Fusarium culmorum colony showing the orange coloration common on certain brands of PDA. Different brands can influence the coloration to be darker, almost red. Image 3 shows a close up of sporodochia which are also orange in color. Spores are commonly mistaken for F. crookwellense or F. sambucinum, but F. culmorum are usually 3-4 septate with a notched basal cell (no 'foot' shape), and the spores are very wide (often compared to maggots in our lab).
