Habitat Summary for element in Georgia: Dry, sandy areas, outcrops, roadsides
Pale yellow-green thallus made up entirely of branching podetia (although a primary thallus of small squamules may be seen on young thalli growing on wood); branches thick, coarse, lax, tangled, the cortex of larger branches often wrinkled; branches tipped with red apothecia, common in some populations & almost entirely absent in others, or a mix of red-fruited & sterile thalli; CHEMISTRY: several chemical races exist, but in Ga. thalli are often PD+ yellow (baeomycesic acid) & sometimes have enough didymic acid to react KC+ blue-green; FIELD ID: unmistakable, with experience, even when sterile; look for lax, coarse thalli, yellow-green color, wrinkled cortex on larger branches; red apothecia clinch ID
Other red-fruited Cladonia species have primary thalli and are not long & multi-branched
None
Dry, sandy areas, outcrops, roadsides, usually on sandy soil, detritus, & rock, where often loose & vagrant; or interspersed with bryophytes or spikemoss (Bryodesma); occasionally attached on old dry wood, often as a scattering of young thalli
Terricolous fruticose lichenized fungus, photobiont a chlorococcoid alga in genus Trebouxia or Pseudotrebouxia
