Tricholoma saponaceum, also known as the Soapy Trich, is a medium to large agaric with a rounded to flattened hat, often appearing humped. The cap is usually tinged with olive and may have a brownish centre on the disc. The gills are close together, and the stalk is thick, staining reddish when bruised. It often grows in association with trees such as pines, spruces, and other types of conifers. It tends to prefer acidic soils and is also known to thrive in damp and mossy environments.

Cap convex, becoming broadly convex or flat, often with a low, broad, rounded hump. The outline typically has irregular lobes or folds and splits. Cap occasionally is off-centre of the stem. Colour varies between greyish-green, yellowish-green, grey, blackish, copper coloured, or brownish. Gills white, becoming reddish spotted, emarginate, fairly distant. Stem more or less equal or slightly thicker below, sometimes tapered at base; often bent. Surface smooth to fibrillose or minutely scaly; white of weakly flushed with cap colours, brownish pink at the base. The stem has no ring. Spore print white.

Microscopic Features: Spores are ellipsoidal, smooth, measuring 5-7 x 3.5-4μm, and lack amyloid content.
