Abstract

In Tunisia, oak forests are widespread chiefly in the Northwest regions where they play an important ecological and socio-economical role. In September 2006, cankers and dieback of branches were observed in Quercus afares and Q. canariensis trees in the reserve of Aïn Zena near Aïn Draham (north-west Tunisia). Fungal isolates obtained from twigs and branches showing sunken necrotic bark lesions were identified as Botryosphaeria corticola on the basis of morphological characters as described by Alves et al. (2004).
