It depends on which toxic substances are present in the soil,whether it 
is usefull to use micro-organisms for remediation. In literature positive 
results have been claimed for PAH (up to four rings: by bacteria, fungi 
like Phanerochaete chrysosporium and Trametes versicolor can also degrade 
PAH with more than 5 rings)

Another mushroom you could try is Stropharia rugoso-annulata, which can 
be easily ordered from a spawn manufacturer.

For other substances like PCB's and creosoot, mineral oil etc. it seems 
also possible to use micro-organisms, butthese have been studied less.

P.S. If heavy metals are present in the soil (not uncommon after mining 
practices) its no use to go for the bioremidiation option.
