Also, the sexual genus Apiospora should be treated as an Arthinium synonym since Arthinium is an older and more frequently found genus. Since Arthrinium species are morphologically variable, a comprehensive molecular analysis was conducted in 2013 to circumcise the Arthrinium genus.Ĭrous and Groenewald suggested that the related genera Pteroconium and Cordella should be treated as synonyms for the Arthrinium genus and that conidia shape and the presence of septae are not reliable markers for distinguishing all species in this complex. Until recently, Arthrinium classification was based on morphological characteristics such as conidial and conidiophores shape, the presence or absence of sterile cells, and septae. The genus Arthrinium was described in 1817 and in earlier literature was known by its synonym Papularia. sacchari, as they produce compound 3-nitropropionic acid (3-NPA), a highly toxic and potentially fatal compound. They can also be found indoors, on water-damaged, composite wood and plywood, plaster, wallpaper, and painted surfaces. It is a widespread and diverse genus: some species are plant saprobes endophytes of plant tissue, lichens, and marine algae plant pathogens on barley and wheat and human pathogens causing cutaneous infections. caricicola as the type species, isolated from the Carex plant (Cyperaceae). Today, this genus contains 91 species, with A. The genus was introduced in 1817 by Schmidt and Kunze and confirmed by Fries in 1832. Arthrinium is a fungal genus that belongs to the family Apiosporaceae, order Xylariales, and class Sordariomycetes within the Ascomycota phylum.
