Microfungi associated with dying Euphorbia mauritanica in South Africa and their relative pathogenicity.

ABSTRACT: Euphorbia mauritanica is a succulent shrub that is indigenous to South Africa and widely distributed throughout the country. Dying plants have been observed in their natural habitat in the Northern and Western Cape Provinces of South Africa in recent years. Stems displaying lesions were collected and the emerging cultures were identified based on ITS, LSU, ACT, RPB2, TEF1 and/or TUB2 sequence data. Four filamentous fungi were consistently observed and isolated. One was identified as Alanphillipsia (Ala.) aloes, and the other three were new to science and are described here as Cytospora euphorbiicola sp. nov., Nothomicrosphaeropsis namakwaensis sp. nov. and Austrophoma (Aus.) euphorbiae gen. et sp. nov.</
