Heteroplacidium compactum is a species of areolate, crustose lichen in the family Verrucariaceae. It has a cosmopolitan distribution. It is a lichenicolous lichen, growing as a facultative parasite on other lichens, typically on non-calcareous rock. It has rod-shaped (bacilliform) conidia measuring 5–7 μm long, and ascospores that are 11–18 by 8–10 μm.[2] Heteroplacidium zamenhofianum is a closely related species distinguished by having perithecia situated in the algal layer, and smaller ascospores (14–16 by 6–7 μm) with a more narrow ellipsoid shape.[3]

The lichen was originally described in 1857 by Italian lichenologist Abramo Bartolommeo Massalongo as Placidium compactum. After having been shuffled to various genera in its taxonomic history,[1] it was transferred to Heteroplacidium in 2008 following molecular phylogenetic analysis of that genus.[4]
