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.^[3]
• 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.^[3]
• Spores: The spore print is pale buff. The ellipsoid-shaped basidiospore of C. epibryus are 7-9 by 3-3.5 µm in size.^[3]
• Absent features- No stipe (stem) or annulus (ring).

Similar species
