Swiss lichenologist Johannes Müller Argoviensis first proposed Aspiciliopsis as a section of the genus Placodium in 1884.

The surface varies in colour from a pale olive-green to grey-green when wet, and a light pinkish white to grey-white or off-white when dry.

It lacks isidia, pseudocyphellae, or soredia — types of vegetative reproduction structures commonly found in other lichens.

The paraphyses, sterile cells interspersed among the asci, are slender and occasionally branch and anastomose, with slightly thickened tips.

Ascospores are arranged in a single row within the ascus and are simple, broadly ellipsoidal, colourless, and thin-walled.

[5] Conidiomata, structures that produce asexual spores called conidia, are immersed in the thallus and measure 250–275 by 130–150 μm in diameter.
