It is commonly known as a variable oysterling in the United Kingdom and is seen there in autumn.[2] May occur solitary, but more often in small scattered groups from summer to autumn on twigs and other woody debris of broad-leaved trees.

Description
- Cap: The cap (pileus) of C. variabilis is generally about 0.5 to 2 cm in diameter is white and emerges kidney shaped soon becoming irregular and wavy forming patches of overlapping fruit bodies. The surface is very finely downy to velvety with a more or less smooth margin.[2][3]
- Gills: On the underside, the gills (lamellae) appear somewhat fringed and are classified as free with no stipe to connect to. The colour of the gills depends on maturity ranging from off-white when young to ochraceous flesh-coloured as the spores mature.[2]
- Spores: The spore print is pinkish-buff, reflecting the colour of the gills. The ellipsoid-shaped basidiospore of C. variabilis are 5.7 by 3-3.5 µm in size.[2]
- Absent features: No stipe (stem) or annulus (ring).
