Mushroom and Spotted Dog Lichen

An unidentified mushroom growing through moss and (I think) Spotted Dog Lichen at Brown-Lowery Provincial Park.

"The brown- to black-coloured 'warts' on the upper surface contain tiny colonies of bacteria that extract nitrogen from the atmosphere for use by the lichen and the algal partner. The name Peltigera is from the Latin pelta, which means 'a light shield'. The name refers to the round shield-like shape. The species name, aphthosa, is from the Greek aphthai, meaning 'an eruption or pustule'. The name refers to the dark-coloured 'warts' on the upper surface of this lichen."
