Tricholoma stans

Species mycorrhizal with pines, especially Pinus sylvestris and Pinus nigra, on calcareous soils, with a convex to flattened cap, with an obtuse umbo, 4 to 8 cm in diameter, with a surface slimy in wet weather, reddish-brown, darker in the center, emarginate white gills that become spotted with development, a whitish cylindrical stipe without an annular zone, with reddish-brown fibrils, and a mealy odour and taste.

Filamentous cuticle composed of cylindrical hyphae arranged more or less parallel to slightly intertwined with each other, 3.5 to 6 µm wide, with an encrusting brown intracellular pigment inside, septate with simple septa (without clamp connections).

Without cystidia.

Lamellar trama regular or parallel.

Basidia cylindric-clavate, 20 to 30 µm long by 5 to 6 µm wide, with a simple base and tetrasporic.

Spores ellipsoidal, smooth, hyaline, thin-walled, with an eccentric apiculus at one end, 5 to 6.5 µm long by 3.5 to 4.5 µm wide, generally with a large oil or lipid drop inside (guttulate), and inamyloid in Melzer's reagent.
