Abstract

The genus Fusarium harbours important plant pathogens and mycotoxin producers. One of the economically most important species is F. oxysporum, that comprises over one hundred formae speciales as well as saprophytic and antagonistic strains. F. oxysporum belongs to section Elegans, together with F. redolens. The questionable morphological distinction between the latter two species has been the subject of many studies [1, 3, 4, 7, 11]. Sequence analysis of part of the 28S ribosomal RNA gene indicates that Elegans is most closely related to Liseola [5]. The section Liseola comprises many mycotoxin-producing species such as F. fujikuroi, F. proliferatum, F. sacchari, F. subglutinans and F. verticillioides. The distinction between section Liseola, without chlamydospores, and Elegans, with chlamydospores, is increasingly questioned and a new section, Dlaminia, has even been proposed to accommodate species such as F. dlaminii that combine characteristics of both sections [6].
