Mycetosoritis. — Our single species, M. hartinani (Fig. 189), isa small brown ant, which lives in the sand of the Texan post-oakwoods. Here it builds small craters, the openings of which run downvertically into the sand to a depth of 24-79 cm., suddenly dilating atlong intervals into two to four subspherical chambers, which varyfrom cm. in diameter (Figs. 190 and 191). As a rule, thesechambers, which are thus strung along the gallery like beads on athread, increase in size with the depth. While excavating theirchambers the ants leave the rootlets of plants dangling into them assuspensoria for their fungus gardens. These consist of flower anthers THE FUNGUS-GROWING ANTS. collected fro
