It is not uncommon for the fruiting body of a wood-decomposing fungus to appear to arise from the forest floor when it is actually attached to a piece of buried wood in the ground or covered by leaf litter. As such, one should examine the base of the fruiting body to see if this is the case. Otherwise, a species that is associated with decaying wood might be mistaken for a species that is ectomycorrhizal. Conversely, the fruiting bodies of some species of ectomycorrhizal fungi sometimes occur "perched" on a piece of woody debris. This is not uncommon for some species of Russula and Scleroderma.
