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.
