Abstract:
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. altensteinii, 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.Keywords: CATENULOSTROMA; CLADOPHIALOPHORA; DACTYLARIA; ITS NRDNA; LSU NRDNA; OCHROCONIS; PHAEOMONIELLA; SACCHARATA; SYSTEMATICS; TERATOSPHAERIA

- Persoonia aims to publish papers dealing with molecular phylogeny and evolution of fungi. A further aim is to promote fungal taxonomy by employing a polythetic approach to clarify the true phylogeny and relationships within the kingdom Fungi. The journal publishes high-quality papers elucidating known and novel fungal taxa at the DNA level, and also strives to present novel insights into evolutionary processes and relationships. Papers to be considered include research articles, topical and book reviews.
Papers are published using a Fast Track system. This implies that the papers are immediately published online and freely available through the internet via this website. For effective publication under the International Code of Botanical Nomenclature the online published papers will be distributed in printed form to several libraries at the same time.
Hard copy volumes: Twice a year (June and December) the online published papers will be bound. These volumes new style will be in A4 format and full colour and will be available through the Publications Department of the National Herbarium of the Netherlands.
Persoonia is a journal published jointly by the Nationaal Herbarium Nederland and the Centraalbureau voor Schimmelcultures.
