Cystodermella cinnabarina is a basidiomycete fungus of the genus Cystodermella. Its fruiting body is a small agaric bearing a distinctive reddish-coloured grainy cap. It occurs in coniferous and deciduous forests throughout the world. Prior to 2002, this species belonged to genus Cystoderma, subsection Cinnabarina, under the name Cystoderma cinnabarinum which is still sometimes applied. Another often used synonym is Cystoderma terreyi.

The species was first described as Agaricus granulosus var. cinnabarinus by German botanist Johannes Baptista von Albertini and the American Lewis David de Schweinitz in 1805. The species has also been known variously as Agaricus terreyi (Berkeley and Broome, 1870),Armillaria cinnabarina (Kauffman, 1922),Lepiota cinnabarina (Karsten, 1914), and Cystoderma terreyi (Harmaja, 1978).

The cap is hemispherical in shape at first, becoming convex and finally flat with maturity, and reaching a diameter of up to 8 cm (3.1 in). The cap cuticle is cinnabar, brick-red or rusty orange and densely covered with fine granules. The flesh is white to pallid, with a mild fungoid taste and barely discernible smell. The gills are white to cream, dense and emarginate or adnate. A finely cottony partial veil covers the gills in immature specimens, tearing away to leave behind a delicate ring. The stem is white above the ring, and scaly below, with dark orange squamules. The stem is up to 6 cm (2.4 in) tall and 1.5 cm (0.6 in) in diameter, sometimes bulbous in the base and hollow.
