“…Due to changes in political borders, two species each now only occur in Mozambique (R. deformans and R. le-testui) and Zimbabwe (R. indigoferae and R. bottomleyae) respectively, while R. baumiana was recorded only from Angola. Two rusts, R. atrides and R. bottomleyae, were transferred to the genera Uredopeltis (Wood 2007) and Spumula (Thirumalachar 1946), respectively. Wood (2006) recorded R. ornata for the first time in South Africa and During the course of recent surveys, aiming at recollecting the majority of Ravenelia species from South Africa and especially at investigating all known Acacia s.l.…”

The genus Ravenelia (Pucciniales) in South Africa

The genus Ravenelia represents the third largest genus of rust fungi and parasitizes a great number of leguminous shrubs and trees, mainly in the subtropics and tropics. Molecular phylogenetic analyses of this genus using nc 28S rDNA and CO3 sequences are presented with a special focus on South African representatives of Ravenelia. Many of the specimens had been collected by us in recent years, mainly from acacia species of the genera Vachellia and Senegalia. Morphological characters were extensively studied using light microscopy and scanning electron microscopy. The analyses resolved several well-supported phylogenetic groups. By linking these groups to their morphology and life cycle characteristics, it was possible to interpret the outcomes in terms of their evolutionary ecology and biogeography. Several characters previously used to define subgeneric groups within Ravenelia were found to be misleading because of assumed convergent evolution. However, host associations, the ability to induce aecial galls as well as the development of two-layered probasidial cells emerged as useful criteria for inferring monophyletic groups. Six novel Ravenelia species were discovered and described. Furthermore, five species represent new reports for South Africa, species descriptions were emended for two taxa, and a new host report emerged for R. inornata. Keywords Pucciniales. Raveneliaceae.

“…A total of 49 of these recorded taxa have been recognized meanwhile to represent anamorph states or synonyms of already known species (Crous et al 2006). Thus, about 110 species were added to the South African rust mycobiota during the last 60 years, many of them only recently (e.g., Berndt 2008bBerndt , 2010Berndt and Uhlmann 2006;Mennicken and Oberwinkler 2004;Wood 2006Wood , 2007 indicating that South Africa remains under-collected. An important aspect is that many of the described species have been collected only once or a few times and are therefore incompletely known with regard to morphological characters and variability, host range and geographical distribution.…”

This paper presents new species, combinations, national reports and host records for the South African rust fungi (Uredinales/Pucciniales). Endophyllum mpenjatiense on cf. Hibiscus sp. (Malvaceae), Phakopsora combretorum (anamorph Uredo combreticola) on the new host Combretum apiculatum (Combretaceae) and Uredo sekhukhunensis on Ziziphus mucronata (Rhamnaceae) are described as new species. Dietelia cardiospermi and E. metalasiae are proposed as new combinations to replace Aecidium cardiospermi on Cardiospermum halicacabum (Sapindaceae) and A. metalasiae on Metalasia spp. (Asteraceae), respectively. Four species are new records for South Africa: Crossopsora antidesmae-dioicae on Antidesma venosum (Euphorbiaceae), Phakopsora ziziphi-vulgaris on Z. mucronata, and Uromyces cypericola and Puccinia subcoronata, both on a new host, Cyperus albostriatus (Cyperaceae). The record of P. subcoronata is the first one from outside the New World. Puccinia scirpi is reported as a possible addition to the South African rust fungi. New host records and observations are presented for Pucciniastrum agrimoniae that is recorded on two new host genera and species, Cliffortia odorata and Leucosidea sericea (Rosaceae), Uromyces cypericola whose urediniospores are described for the first time, Phakopsora stratosa in that spermogonia and Uredo-like aecia were discovered, and for Sphaerophragmium dalbergiae in that characters of the urediniospores are re-evaluated. A lectotype is selected for Aecidium garckeanum and spermogonia are reported for this rust for the first time. The rust fungi of Ehrharta (Poaceae) are discussed and critically evaluated in the light of spore morphology and host species.
