“Hi mushroom enthusiasts of Alberta

My husband and I have noticed mushrooms popping up in our yard.  They are dark brown.  They seem to occur in either as a solitary mushroom or in groups, underneath our dwarf conifer plants.  We are in Edmonton by the river valley.  They are growing in a mulched garden bed, near a rocky border.  There are about a dozen of them so far.

We have children and toddlers in the neighborhood, and were wondering if there is any possibility these are poisonous, and if so, how poisonous?  Any assistance you can provide in identifying these mushrooms would be greatly appreciated.  Thank you”
