dc.description.abstract |
The genus Ophiostoma (Ophiostomatales) has a global distribution and species are best known for
their association with bark beetles (Curculionidae: Scolytinae) on conifers. An unusual assemblage of these fungi is closely associated with the African endemic plant genus Protea (Proteaceae). Protea-associated Ophiostoma
species are ecologically atypical as they colonise the fruiting structures of various serotinous Protea species. Seven species have been described from this niche in South Africa. It has been speculated that novel species may be
present in other African countries where these host plants also occur. This view was corroborated by recent collections of two unknown species from Protea caffra trees in Zambia. In the present study we evaluate the species
delineation of these isolates using morphological comparisons with other Protea-associated species, differential growth studies and analyses of DNA sequence data for the β-tubulin and internal transcribed spacer (ITS1, 5.8S, ITS2) regions. As a result, the species O. protea-sedis sp. nov., and O. zambiensis sp. nov. are described here
as new. This study brings the number of Protea-associated Ophiostoma species to nine and highlights the need for more inclusive surveys, including additional African countries and hosts, to elucidate species diversity in this
uncharacteristic niche. |

We thank the Western Cape Nature Conservation
Board for issuing the necessary collecting permits. We also thank the National
Research Foundation (NRF) and the NRF/DST Centre of Excellence
in Tree Health Biotechnology (CTHB) for funding, as well as colleagues at
the Forestry and Agricultural Biotechnology Institute (FABI) and the Centraalbureau
voor Schimmelcultures (CBS) for making cultures available
for study. We appreciate assistance from Prof. J. Roux in the collection of
specimens from Zambia. |
