The aim of this research was the early detection of fungal attack on the surfaces of modified and unmodified wood after natural weathering. The investigation was carried out by molecular techniques and the development and establishment of genus/species specific PCR for important moulds and sapstain fungi was part of this work. After adaption of the method, a monitoring of the succession of Ascomycetes on surfaces of modified wood with and without coatings after natural weathering started. After 3 months of natural weathering all panels were infestated by Ascomycetes. All modifications and coating systems were more affected by Aureobasidium pullulans than by Cladosporium sp. Over the investigation period of twelve months no Trichoderma sp. and no Aspergillus sp. were detected.
