Phragmidium satoanum, a new rust pathogen of Rosa hirtula in Japan

A review of plant leaf fungal diseases and its environment speciation

“…Later, pustules form and turn yellow-green and eventually black. Severe infestations cause foliar chlorosis, deformation, and eventual abscission [23].…”

Four new Phragmidium (Phragmidiaceae, Pucciniomycetes) species from Rosaceae plants in Guizhou Province of China

“…Phragmidium rosae-roxburghii was the first species of Phragmidium described on Rosa roxburghii. It is easily to distinguish species by its unique square to diamond-shaped urediniospores, since in other Phragmidium species the urediniosporas are oval to nearly spherical (Yun et al 2011;Ono 2012;Zhuang et al 2012;Yang et al 2015;Liu et al 2018Liu et al , 2019Liu et al , 2020Ono and Wahyuno 2019). In phylogeny, this species only kept a close relationship to Ph.…”

“…Based on morphological features or host associations, 1200 species belonging to 71 genera of 15 families were previously reported in China. Over 70 Phragmidium species have been described (Cummins 1931;Arthur 1934;Zhuang et al 1998Zhuang et al , 2003Zhuang et al , 2005Zhuang et al , 2012Wahyuno et al 2001;Yang et al 2015;Ali et al 2017;Aime et al 2018;Liu et al 2018Liu et al , 2019Liu et al , 2020Ono and Wahyuno 2019;Aime and McTaggart 2021;Zhao et al 2021).…”

“…The combination of morphological and molecular characters has been applied in the taxonomy of rust fungi (Beenken et al 2012;Beenken 2014;McTaggart et al 2016McTaggart et al , 2017Liu et al 2018Liu et al , 2019Liu et al , 2020Ono and Wahyuno 2019;Zhao et al 2021). Phragmidium includes more than 270 epithet records which are listed in MycoBank (https://www.mycobank.org) and Index Fungorum (http://www.indexfungorum.org) (accessed in October 2022).…”
