New species of rust fungi (Uredinales) from South Africa and new observations on known species

Abstract

Four new species and a new variety of rust fungi (Uredinales) are described from South Africa: Puccinia montis-venenosi on Galium spurium ssp. africanum and G. tomentosum, P. naufraga on Helichrysum sp., Uredo fynbosense on Phylica oleifolia and Ph. buxifolia, Uromyces eclipsis on Zygophyllum morgsana, and Puccinia lycii var. bizonata on Lycium sp. Puccinia austro-africana is proposed as a new combination for P. tetragoniae var. austro-africana on Tetragonia. New observations are presented about already known species: The uredinial stage of Uromyces pentaschistidis is described; Uredo monechmatis is newly reported for South Africa on new hosts and its uredinial morphology is described; a detailed description is provided for the poorly known P. anthospermi; the identity of Uredo zygophylli, U. zygophyllina and Uromyces dinteri is discussed; a key is presented for the known Puccinia species on Helichrysum in South Africa.

A dynamic, web-based resource to identify rust fungi (Pucciniales) in southern Africa

“…Firstly, a list is outdated after any taxonomic change or new discovery. For example, since Berndt (2008b) compiled the latest list of rust fungi for southern Africa, at least four new species were described (Berndt 2008a;Maier et al 2015;Martin et al 2017;Wood et al 2014), several new species reported (Berndt 2009;McTaggart et al 2015b;Mostert et al 2008;Mostert et al 2010;Roux et al 2013) and names changed (Beenken and Wood 2015;Berndt 2008a). Secondly, lists often do not provide information on morphology or how to identify taxa.…”
