Scleropyrenium is a genus of squamulose (scaly) lichens in the family Verrucariaceae. It has two species.[1] The genus was circumscribed in 1993 by Japanese lichenologist Hiroshi Harada, with S. japonicum as the type species. Characteristics of the genus include a dark brown to almost black exciple (the rim of tissue around the hymenium), pycnidia of the Staurothele-type, and a pachydermatous upper cortex.[2]
