Caloplaca aliciae has a
thallus that can reach up to 2 cm in width, with a colour ranging from dull pink to dull brown. The thallus is typically indistinct and , comprising small, dispersed, flat and minute
apothecia that are immersed in the thallus. The areoles, measuring 0.4–0.7 mm wide and 120–150
μm thick, are irregularly shaped, often elongated, and sometimes dissected by tangential cracks up to 75 μm wide. These areoles are typically dispersed, occasionally aggregated, and separated by broad cracks, revealing the rock surface beneath. The surface of the areoles is characterised by a whitish, dull pink, or dull orange-brown colouration and has a or slightly eroded texture. The apothecia of
Caloplaca aliciae are in form, ranging from 0.2 to 0.6 mm in diameter. Initially immersed, they eventually elevate distinctly, sometimes rising slightly above the level of the areole. Each areole typically contains one to two apothecia. The of the apothecia is the same colour as the thallus, with shades of dull pink, whitish-brown, or brownish. The exciple is , with a
hymenium reaching up to 100 μm in height and a yellowish-brown . The is approximately 60 μm thick, with an below the .
Paraphyses are slightly widened towards the tips, and
asci tend to contain spores of varying sizes. are slightly attenuated at the ends, measuring 12–14 by 5–6 μm, with a
septum thickness of 5–8 μm. ==Similar species==
