Earthstars, Puffballs & Stinkhorns
This group includes mushrooms belonging to class Gasteromycetes. Some of the fungi, although visibly similar, are from different groups: Scleroderma, Pisolithus & Melanogaster belong to the order Boletales. Some mycologists don't recognize Gasteromycetes and lump all these mushrooms into the class Basidiomycetes instead.
