More on the Earth Fruit
In Texas, Geocarpon minimum occurs in a saline barren complex, just above the floodplain of the Neches River. The vegetative edge is sometimes called a "cryptogrammic lip" referring to the lichen species that concentrate at the edge of the slicks and the lack of competition with other vegetation that is found there. The local soils are not mapped at this level of detail but appear to be clay pans, holding late winter rains with a spongy feel to the soil and drying off quickly into a hard cement. The Earth Fruit grows where little other vegetation can.
