These are puffballs that resemble horse dung. They have a tough, leathery outer skin full of a fleshy material when young, but in mature specimens, this turns into brown spore dust that is released when the skin dries, ages and ruptures – Wikipedia says “Pisolithus tinctorius is also a major component in Mycorrhizae fungi mixtures that are used in gardening as powerful root stimulators.” – I will post younger specimens soon.
