Name: Spongiforma squarepantsii

Common Name:  Spongebob Squarepants Mushroom

Family: Boletaceae

How it made the Top 10:  Named after the cartoon character Spongebob Squarepants, this new species looks more like a sponge than a stereotypical mushroom and its fruiting body can actually be squeezed like a sponge and bounce back to its normal size and shape. This unusual mushroom is only the second species of the bolete fungus genus Spongiforma and according to the authors, “its unusual shape is unlike anything else known.”  Beyond having a shape that brings Spongebob Squarepants to mind, the authors note other similarities between the fungus and the cartoon personality. The mushrooms smells fruity and Spongebob lives in a pineapple; magnified, the texture of the fungus resembles the tube sponges covering the seafloor where Spongebob lives; and even the microscopic spores of the fungus appear spongelike. Although the species name was initially rejected by journal editors as "frivolous," the authors persisted and as a result, brought attention to a bizarre new species and to the biodiversity of the world’s forests.
