Alternaria hyacinthi (de Hoog & P.J. Mull. bis) Woudenb. & Crous 2013

This fungus infects Hyacinthus and other plants. It is the type species of the section Embellisioides, a group of Alternaria species that have been described by Woudenberg et al. (2013) as having "simple, septate conidiophores, straight or with multiple, geniculate, sympodial proliferations. Apical or lateral, short secondary conidiophores may occur. Condia are solitary or in short chains, obovoid to ellipsoid, with transverse and longitudinal septa; transverse septa can be thick, dark and rigid in contrast to the external wall. Chlamydospores and a sexual morph may occur."
