Clitocybe metachroa, also known as the Twotone Funnel Cap, is a smallish agaric mushroom found primarily in woodland environments across Europe and North America. This intriguing species belongs to the large and diverse Clitocybe genus, characterized by its funnel-shaped cap, which ranges in colour from greyish-brown to pale beige, often with a slightly darker centre. The cap is hygrophanous, meaning it changes colour as it loses moisture, drying to a more pallid, lighter shade. The pictures shown here were taken in moist weather.

Cap buff or tan, hygrophanous, and becomes more pallid as it dries. Initially convex, it later develops into an infundibuliform (funnel-shaped) form, with a smooth surface and a finely striate margin that becomes more prominent in moist weather. The flesh is white or greyish and thin. Gills whitish-grey, decurrent, fairly broad, and crowded. Stem concolourous with the cap, smooth, and silky, more or less equal in thickness but with a swollen, woolly base. It lacks a ring. The flesh is white or greyish, thin, and may be hollow or stuffed. Spore print white.

Microscopic Features: The spores are hyaline, smooth, ellipsoid, and non-amyloid, often containing droplets. They measure 5-7 × 3-4 µm.

Synonyms: Clitocybe dicolor.
