Neckeropsis pocsii is a species of moss in the family Neckeraceae that is endemic to Mayotte. It is considered a critically endangered species.
N. pocsii is known only from the type location, west of Benara on Grande-Terre, Mayotte, where it grows on boulders in mesic evergreen forest.[1]
N. pocsii plants are medium-sized, green in colour, and slightly glossy. They are flattened in habit, similar to Neckeropsis disticha. The rhizoids are brownish-orange in colour, smooth, and sparsely branched. The stems grow to long and wide, with leaves growing to approximately by . The leaves are asymmetric and flattened when damp, becoming twisted when dried out. When in the sporophyte stage, plants produce capsules on upright stalks that grow to tall. The capsules are brown and cylindrical, measuring by .[1]
N. pocsii is listed as critically endangered by the International Union for Conservation of Nature under criteria B1+2c, based on its extremely limited distribution and the decline of its habitat. It is threatened by excessive logging in the area.
