Cetraria aculeata, the spiny Iceland lichen, is a dark brown to black fruticose lichen in the family Parmeliaceae. First described by Schreber in 1771 as Lichen aculeatus, it was transferred through several genera before being placed in Cetraria. The thallus forms shrubby tufts up to 5 cm (2.0 in) tall and reproduces mainly by fragmentation rather than ascospores.
