Summary of description from Leslie, Summerell and Bullock- The Fusarium Laboratory Manual:

Characters on PDA - relatively slow growing, mycelium is floccose with rose to bergundy pigmentation that can be greyish rose at periphery. Sporodochia form in the center of the colony, in a small central spore mass and are pale orange to dark brown. Red pigments (sometimes brown) are formed in the agar.

Macroconidia typically 5-septate, but can be 3- & 4-. Microsconidia are not a reliable taxonomic indicator, and isolates which produce them have not been compared molecularly.
