The plants of this genus are typical representants of the family: The rounded leaves are very hollow and imbricate, so that the stems are rounded like worms. The edges of the leaves are finely denticulated. A midrib doesn't exist or is short and double. The cells of the leaf blade are elliptic and with spiny papillas.
The leaves of the species Myurella tenerrima (="Myurella apiculata (Sommerf.)BSG") are characterised by a long and clearly distinguished acumen. The teeth on the leaves edge are small and consist only of some projecting cell corners.
The species forms small slighlty bluish or yellowish-green turfs, often between other mosses in cracks or on earthy rocks. The plants are small, 1-2cm long, and more or less unramified. The species can be found in northern europe, and in germany only in the alps and in the Allgäu.
