Thickpoint Grimmia grows in rounded cushions or flat patches 1-3cm high. It usually looks quite hoary due to a hair point at the tip of the leaves. The capsules are largely hidden by the leaves that sheath them, but are reddish-brown, elongate and cylindrical.
This moss prefers calcareous walls, and can be found on blocks of limestone and base-rich sandstone. It can also be found on man-made substrates like tarmac, concrete and masonry in unshaded or partially shaded sites. Common and widespread throughout.
