The objective of the study was to investigate the impact of chopped wheat straw (CWS), ground corn cobs (GCC) and commercial pellets (CP), as inoculum carriers, on both growth and polycyclic aromatic hydrocarbons (PAH) degradation performances of Dichomitus squalens, Pleurotus ostreatus and Coprinus comatus. A historically-contaminated soil (HCS) and creosote-treated shavings (CTS) from the Soběslav wood preservation plant, characterized by different relative abundances of the PAH bioavailable fractions, were used to assess the contaminated matrix effect and its interaction with both carrier and fungal strain. The best PAH degrader appeared to be the strain P. ostreatus CCBAS 278 cultivated on commercial pellets that was able to remove 80 percent of total PAH sum from HCS
