Alternaria chartarum Preuss 1948
This fungus is widely distributed and infects woody plants, causing leaf spot and leaf blight diseases. A. chartarum is the type species of the section Pseudoulocladium, a group of Alternaria species that have been described by Woudenberg et al. (2013) as having "simple or branched conidiophores with short, geniculate, sympodial proliferations. Conidia are obovoid, non-beaked with a narrow base, in simple or (mostly) branched chains. Apical secondary conidiophores with multiple conidiogenous loci and lateral secondary conidiophores with a single conidiogenous locus can be formed."
