Crepidotus variabilis (Pers.) P. Kumm. 1871

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.^[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. Very common but often confused with Crepidotus cesatii.^[3]

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).
