Inside the fungus garden of a Cyphomyrmex ant colony.  Cyphomyrmex gardens are unusual among the fungus-growing ant genera in that the fungus grows as a yeast.  The fungi are visible here as small yellow globs.  Notice how difficult it is to see the ants themselves- several workers are present at the right side of this photograph.  Cyphomyrmex tend to freeze when disturbed, making them look like little pieces of soil.
