About Tricholoma argyraceum (Bull.) Gillet
The cap of Tricholoma argyraceum starts conical before flattening into a convex shape, with a distinct raised central boss. It measures 1.5 to 6 cm (0.59 to 2.36 in) in diameter, and is covered in greyish scales that are paler than those found on other grey-capped tricholoma species. The crowded gills are white or pale grey, and are either emarginate or adnate in cross section; they sometimes stain yellowish when damaged. The thin flesh is cream or white, with a farinaceous (floury) and somewhat rancid taste and odor. The whitish stipe is 2–5 cm (0.79–1.97 in) tall and 0.3–0.8 cm (0.12–0.31 in) wide, lacks a ring, and has a tapering base. The poisonous species T. pardinum has a similar appearance, but has coarser cap scales, while T. scalpturatum has a darker cap that does not have a central boss. Tricholoma argyraceum grows across Europe, and is uncommon across its range. Its fruit bodies develop from June to December, and occasionally appear earlier in spring. This species forms ectomycorrhizal associations with trees from multiple genera: birch (Betula), Carpinus, oak (Quercus) and Tilia.
