How do you identify Alternaria?

How do you identify Alternaria?

The identification of Alternaria species requires a combination of morphological features and molecular methods. Morphological features such as conidial shape, size of primary conidium, conidial branching arrangement and primary conidiosphore length were used in the identification by Simmons and Roberts (1993).

What is the class of Alternaria?

DothideomycetesAlternaria / ClassDothideomycetes is the largest and most diverse class of ascomycete fungi. It comprises 11 orders 90 families, 1300 genera and over 19,000 known species.
