It is found in coniferous woodlands in Europe, and has also been encountered under introduced pine trees in Australia and New Zealand.

[8] Bon mentions that T. myomyces has been defined for lowland mushrooms with white gills and a fleecy cap and Courtecuisse separates it on the same basis.

[11] The cap is 4–7 centimetres (1+1⁄2–2+3⁄4 inches) wide and evenly covered in fine grey scales.

The whitish flesh is thin, easily broken, and has a pleasant mild (not mealy) smell and taste.

[17] A 2024 study also tested for and concluded that toxin levels were negligible enough for T. terreum for it to be considered an edible mushroom.
