The Occurrence of Phellinus torulosus in Apulia and Basilicata (Southern Italy) : IDentification of Isolates by Morphologic, Microscopic, and Molecular Means

Basidiomes of Phellinus torulosus were found in 9 oak woods in Apulia and Basilicata (Southern Italy); from these basidiomes 138 isolates of P. torulosus were obtained and identified by their morphologic, microscopic, and molecular characteristics. Based on the type of aerial mycelium (fluffy, cottony or powdery) and its growth, 9 morphotypes were identified. The morphology of the cultures was not correlated with the microscopic character of the 9 morphotypes. Molecular analysis, such as intergenic transcribed spacers-restriction fragment length polymorphism (ITS-RFLP) and sequencing of the ITS region, confirmed the results obtained with microscopy analysis
