**2.1. Wollenweber and Reinking**

The basis for all modern taxonomic systems of *Fusarium* species is the work of Wollenweber and Reinking, which was published in "Die Fusarien" in Germany. In this publication, 16 sections, 65 species, 55 varieties, and 22 forms of *Fusarium* were introduced, which were separated based on the morphological differences [2]. Prior to this publication, about a thousand *Fusarium* species had been described, often a different species for every host. Wollenweber and Reinking offered an order to a chaotic situation of *Fusarium* taxonomy. In their taxonomic system, each section contained species that were united by critical morphological characteristics (e.g., macroconidia morphology and pigment). Each section contained only a few species. Other taxonomists used the sections created by Wollenweber and Reinking to develop their taxonomic systems.

#### **2.2. Snyder and Hansen**

During 1940s and 1950s, Snyder and Hansen in the United Sates (US) developed a new taxonomy system and reduced number of species of *Fusarium* to nine [6, 8, 9]. Their identification was based on using cultures derived from single spores. The Snyder and Hansen species taxonomy was easy to use and identify any *Fusarium* isolate to species level.
