Tricholoma atrosquamosum, commonly known as dark-scaled knight, is an edible gilled mushroom native to Europe.

The grey-capped fruit bodies are generally found singly or in small groups in deciduous woodland on chalk-based soils.

[1] The fruit bodies appear under deciduous and coniferous trees, particularly beech and spruce on chalky (calcareous) soils.

Variety squarrulosum is also rare (though more widely distributed in southern Europe), and associated with oak, pine and spruce on chalk soils, with its fruit bodies appearing September to November.

[3] They can be confused with darker specimens of the poisonous T. pardinum, which is generally a larger mushroom and lacks the peppery aroma.
