Habitat Summary for element in Georgia: Upland and bottomland forests and woodlands with pine component
Pale blue-green primary thallus (though soredia can appear yellow-green when wet), sometimes minute & scale-like, usually revolute, with some forming linear lobules (as in photo), though more commonly sorediate, with a variably maculate upper surface; larger squamules can form in bark cracks or in low-light situations, up to 1 mm long, appearing more feathery and loosely sorediate; podetia variable (often absent), 1-5 mm long, usually lumpy but corticate, simple to multi-branched, occasionally with patches of soredia, tipped with red apothecia or pycnicia, both of which can blacken (with age?); sterile thalli can be told by the small, revolute, bluish sorediate squamules; CHEMISTRY: K+ bright yellow (thamnolic acid); FIELD ID: unmistakable, especially if fertile; shape & color of squamules usually enough on sterile thalli, with experience
See accounts for Cladonia cristatella, C. abbreviatula, C. hypoxantha, C. incrassata; can be confused with Lepraria harrisiana if sterile thalli dissolve into sorediate masses, but the Lepraria is neater & bluer

Common to abundant status in Ga., where it is likely undersurveyed because small, usually sterile & often growing low on tree; species does not seem to deserve such a low G-rank, at least here
