Alternaria infectoria E.G. Simmons 1986
This fungus is widely distributed in many regions. It infects predominantly wheat, causing "black point" on the grain, dark brown or blackish discoloration around the embryo. However, this disease may be also caused by other fungi. A. infectoria infects various other crops and can sometimes produce mycotoxins.
A. infectoria is the type species of the section Infectoriae, a group of Alternaria species that have been described by Woudenberg et al. (2013) as having "short to long, simple or branched primary conidiophores with one or several conidiogenous loci. Conidia are obclavate, long-ellipsoid, small or moderate in size, septate, slightly constricted near some septa, with few longitudinal septa, in moderately long to long, branched chains. Long, geniculate, multi-locus secondary conidiophores can be formed apically or laterally. Sexual morphs are known, and meristematic growth has been reported."
