Morphological differential features of Fusarium species. (a) F. chlamydosporum: brown chlamydospores in chains and polyphialide, (b) F. napiforme: napiform microconidia (globose with a small protuberance), (c) F. poae: ampuliform microconidia with papilla, 0–1 septate and monophialide, (d). F. pseudonygamai: large microconidia aseptate, (e) F. solani: false heads microconidia, and large monophialide, (f) F. subglutinans: large mesoconidia, fusiform, straight 1–3 septate, and G. F. verticillioides: microconidia in large chains observed on Petri dish under the low power of the microscope 10tx.
