Found in Malaysia, it was formally described as a new species in 2015 by Luxembourgish mycologist Paul Diederich. The type specimen was found on the southern slope of Mount Kinabalu (Kota Belud, Sabah) at an altitude of ; here, in a mossy forest on a mountain ridge, it was found growing on the lichen Anomomorpha cf. roseola. The fungus forms black, convex, rounded typically measuring 100âÂÂ200 üm in diameter; the fungus does not otherwise cause visible damage to the host lichen. Sclerococcum sipmanii is only known to occur at the type locality. The species epithet honours Dutch lichenologist Harrie Sipman, one of the collectors of the type.
