通常被称为面包树、面包棕榈树或苏铁的脑树属植物原产于非洲；该属包括60多种，是非洲本土植物群的重要组成部分。最近，在南非Kirstenbosch植物园的桌山脚下，发现了一种叶枯病。从采自南非的E. alten-steinii、E. lebomboensis和E. princeps的死亡和垂死叶片中初步分离发现，该寄主上存在几种新的微真菌。新发现的细菌包括衣原体、柯氏糖虫、阿氏畸胎绦虫和脑性绦虫。以前只知道发生在变形科的物种的新宿主记录包括Cladophialophora proteae和Catenulostroma microsporum，以及发生在T. encephalarti ascomata上的高寄生虫Dactylaria leptosphaeriicola。
Species of Encephalartos, commonly known as bread trees, bread palms or cycads are native to Africa; the genus encompasses more than 60 species and represents an important component of the indigenous African flora. Recently, a leaf blight disease was noted on several E. altensteinii plants growing at the foot of Table Mountain in the Kirstenbosch Botanical Gardens of South Africa. Preliminary isolations from dead and dying leaves of E. alten-steinii, E. lebomboensis and E. princeps, collected from South Africa, revealed the presence of several novel microfungi on this host. Novelties include Phaeomoniella capensis, Saccharata kirstenboschensis, Teratosphaeria altensteinii and T. encephalarti. New host records of species previously only known to occur on Proteaceae include Cladophialophora proteae and Catenulostroma microsporum, as well as a hyperparasite, Dactylaria leptosphaeriicola, occurring on ascomata of T. encephalarti.
