Ligules are the small structure at the junction of the leaf blade and sheath in grasses, and they vary a lot among turf species. In many grasses the ligule is membranous and thin, sometimes it has a fringe of hairs along its edge, and in some species there is no ligule at all. This range—membranous, hairy, or absent—is what you typically see, making it the best description. The other options describe textures or forms that don’t match the common variation of ligules in turfgrasses.
