NEW RECORDS OF CYLINDROCLADIUM AND CYLINDROCLADIELLA SPP IN SOUTH-AFRICA

Three species of Cylindrocladium (Cm.) and three of Cylindrocladiella (Ca.) were collected from forestry plantations and nurseries in South Africa. These fungi include species previously recorded in South Africa, Cm. scoparium and Ca. parva, as well as new records for the country: Cm. clavatum, Cm. colhounii, Ca. camelliae and an undescribed Cylindrocladiella. Single-conidium isolates of all six fungi tested were pathogenic to Eucalyptus grandis, Medicago truncatula, Arachis hypogaea, Glycine max and Pisum sativum. Only Cm. clavatum was pathogenic to Solanum tuberosum. Cm. species were more virulent than the Ca. species, with Cm. clavatum being the most virulent of all the fungi.
