    Jami, Fahimeh; Marincowitz, Seonju; Slippers, Bernard; Crous, Pedro W.; Le Roux, Johannes J.; Richardson, David M.; Wingfield, Michael J. (Elsevier, 2019-11)
    Acacia koa and A. heterophylla are commonly occurring native trees on the Hawaiian Islands and La Réunion, respectively. A recent phylogenetic study suggested that A. heterophylla renders A. koa paraphyletic, and that the ...
  • Botryosphaeriaceae associated with die-back of Schizolobium parahyba trees in South Africa and Ecuador 
    Mehl, James William Montague; Slippers, Bernard; Roux, Jolanda; Wingfield, Michael J. (Wiley, 2014-10)
    Die-back of Schizolobium parahyba var. amazonicum is a serious problem in plantations of these trees in Ecuador. Similar symptoms have also been observed on trees of this species in various parts of South Africa. The most ...
  • Botryosphaeriaceae associated with Terminalia catappa in Cameroon, South Africa and Madagascar 
    Begoude, Didier (Aime Didier B.); Slippers, Bernard; Wingfield, Michael J.; Roux, Jolanda (Springer, 2010-03)
    Species in the Botryosphaeriaceae represent some of the most important fungal pathogens of woody plants. Although these fungi have been relatively well studied on economically important crops, hardly anything is known ...
  • Botryosphaeriaceae associated with the die-back of ornamental trees in the Western Balkans 
    Zlatković, Milica; Keča, Nenad; Wingfield, Michael J.; Jami, Fahimeh; Slippers, Bernard (Springer, 2016-04)
