Crepidotus epibryus explained

Crepidotus epibryus, is a species of saprophytic fungi in the family Crepidotaceae. It is commonly known as grass oysterling in the United Kingdom and is seen there in late summer and autumn.^[1]

Description

• Cap

The cap (pileus) of C. epibryus is generally about 0.4 to 1.5 cm in diameter and is convex kidney shaped fanned, coloured white or pale buff with upper tomentose (finely felted) surface.^[1]

• Gills

On the underside, the gills (lamellae) are crowded and are classified as free with no stipe to connect to. The colour of the gills depends on maturity ranging from white when young to pinkish brown as the spores mature.^[1]
