Crepidotus variabilis is a species of saprophytic fungi in the family Crepidotaceae. It is commonly known as a variable oysterling in the United Kingdom and is seen there in autumn.[1] May occur solitary, but more often in small scattered groups from summer to autumn on twigs and other woody debris of broad-leaved trees. Very common but often confused with Crepidotus cesatii.[2]
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.[1] [2]
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.[1]
