torf:
3.a - a slab or block of peat dug for use as fuel. But in many districts turfs are distinguished from peats, as being pared from a dry surface, containing roots of grass and recent herbage, and being lighter coloured, while peats are usually dug from a ‘moss’ or bog, and consist chiefly of long-decayed and compressed vegetable matter, black or dark brown, formed from Sphagnum and other mosses.
3.b - collect. as a substance; peat.
