<b><i> Fusarium oxysporum </i> f.  sp.  <i> melongenae </i></b> forms macro- and microconidia, as well as chlamydospores that ensure its dissemination and preservation.
Appearance of microconidia of <b><i> Fusarium oxysporum </i> f.  sp.  <i> melongenae </i></b> clustered in a false head at the end of short monophialid conidiophores.
