Discinella terrestris is a species of fungus in the family Helotiaceae. It was first described as Helotium terrestre by Miles Joseph Berkeley and Christopher Edmund Broome in 1882, from collections made in Brisbane.[3] R.W.G. Dennis transferred it to the genus Discinella in 1958.[4]

Fruit bodies are orange to yellowish-orange discs up to 10 mm (0.4 in) in diameter.[5] The cylindrical eight-spored asci are borne on long stalks, and measure 200–225 by 10–14 μm; spores are elliptical to spindle-shaped, contains two to four oil droplets, and measure 14–25 by 7.5–9 μm. Paraphyses are shaped like narrow cylinders about 2 μm thick, and have rounded tips. The species is found in Australia, where it grows on the floor of sclerophyllous eucalypt forests.[6]
