Syntrichia intermedia (syn: Tortula intermedia)(NL: Vioolsterretje / EN: Intermediate Screw-moss / DE: Haar-Drehzahnmoos / FR: Syntrichia intermédiaire ) is dull green to golden green and grows in tufts or loose cushions. Stems can range from 1 to 4 cm tall. When dry, the approximately 4 mm long leaves are spirally twisted or incurved, giving the plant a distinctive appearance. The leaf is slightly narrowed at the halfway point, the lower half having recurved margins. The tip is rounded and flat. The leaves spread out widely from the stem when moist, but are not strongly recurved. Dry leaves may appear pointed because they fold up along
their length, making them seem tapered at the tip (the rounded tip is an important field character for this species). The stout, reddish-brown nerve projects from the leaf tip into a long, silvery white hair point with small, coarse teeth. Capsules are cylindrical and erect, ripening to a reddish-brown. They are frequent, and are produced in spring and summer.
S. intermedia is usually found in calcareous places. Typical habitats include roofs, calcareous rocks and walls and sunny, exposed, stony ground.
