Pink Earth

11-18-13 Dibaeis baeomyces  009You’ve probably walked right over this lichen a million times and perhaps even thought it was a fungus. To all appearances, Dibaeis baeomyces appears to be colonies of tiny, pink mushrooms, but in fact, those aren’t mushrooms – they are the fruiting bodies, or apothecia, of a lichen (fungus + alga or cyanobacterium) known as “Pink Earth.” If you look closely at these 1/8” bubblegum-colored structures, you’ll see that they are at the apex of tiny stalks that grow out of a gray crusty matter, which is actually the body, or thallus, of the lichen. Look for Dibaeis baeomyces growing in disturbed areas such as roadsides.
