Sclerococcum sipmanii is a rare species of lichenicolous fungus in the family Dactylosporaceae.

Found in Malaysia, it was formally described as a new species in 2015 by Belgian mycologist Paul Diederich.

The type specimen was found on the southern slope of Mount Kinabalu (Kota Belud, Sabah) at an altitude of 2,800 m (9,200 ft); here, in a mossy forest on a mountain ridge, it was found growing on the lichen Anomomorpha cf.

The fungus forms black, convex, rounded sporodochia typically measuring 100–200 μm in diameter; the fungus does not otherwise cause visible damage to the host lichen.

The species epithet honours Dutch lichenologist Harrie Sipman, one of the collectors of the type.
