Importance and distribution

There are 27 Phaeodothis records in Index Fungorum (2022), but several species have been transferred to Clypeococcum, Englerodothis, Microcyclus, Phyllachora and Piptarthron. Phaeodothis comprises 21 species known on a wide range of plants such as Acer negundo (Sapindaceae), Amaranthus sp. (Amaranthaceae), Andropogon cymbarius (Poaceae), Arundo donax (Poaceae), Calamus moti (Arecaceae), Daemonorops (margaritae), Licuala ramsayi (Arecaceae), Nauclea diderrichii (Rubiaceae), Panicum antidotale (Poaceae), Pinus radiata (Pinaceae), Piper sp. (Piperaceae) and Ribes grossularia (Grossulariaceae).
