Hi Yellow012,
Please note that the RHS list xCupressocyparis leylandii as being "notably
susceptible to Honey Fungus (Armillaria sp.) ... so don't enjoy those
mushrooms too much!

Armillaria mellea is edible.

Far better, if you can, to dig those stumps and roots out.
Sorry for the bad news.

That has been a recommendation for centuries, but there is little
evidence that it makes a significant difference. Also, there are
dozens of fungi that are likely to grow on conifer stumps, most
of which are completely harmless to living plants.
