 The underground architecture of fungus-growing ant nests is different from that of most other ants.  Instead of a maze of smaller chambers, most attine ants tend to have relatively few large, rounded chambers where the ants cultivate their fungus.  This nest of Mycetosoritis- one of the smallest of the fungus-growing species- has two chambers in vertical alignment, the deeper one is about 1/2 meter below the surface. Notice at the far right of the photo an old chamber from a defunct colony.
