Tricholoma imbricatum, commonly known as the Matt Knight, is a medium to large agaric distinguished by its dry, finely scaly cap that ranges from reddish-brown to chestnut in colour. The cap surface often appears slightly rough or matt, setting it apart from the more glossy or slimy species in the same genus. This mushroom typically grows in coniferous forests, particularly under pine, where it forms mycorrhizal associations.

Cap convex when young, becoming broadly convex to flat with age. The surface is dry and matt, often finely scaly or fibrillose, with a reddish-brown to chestnut-brown colour that may fade slightly towards the margin. As the cap matures, it can develop small radial cracks or fissures. Gills whitish at first, later showing reddish-brown spotting with age. They are adnexed to adnate, fairly close, and of medium thickness. Stem solid, firm, and cylindrical or slightly club-shaped, ranging from whitish near the apex to brownish below. It is smooth or covered with fine fibrils and lacks a ring. Spore print white.

Microscopic Features: Spores are broadly ellipsoidal to subglobose, smooth, and hyaline, measuring 4–8 × 4–6 µm. They are inamyloid, showing no colour reaction in iodine. The basidia are four-spored, and clamp connections are absent.
