Abietinella abietina is more commonly known as Wiry Fern Moss.
Taxonomy and Systematics
Species: Abietinella abietina
Wiry Fern Moss plants in dull, dark olive green to golden brown mats. Stems are up to 12 cm long, with ends arching upright, once pinnate, resembling a miniature fern leaf. When dry, the leaves are drawn in tight, making the banches look like threads, giving off a stiff and wiry appearance. When wet, the leaves spread slightly, becoming more pliable and bushy, making the plant look fuller. Stem leaves are 1-2 mm long, twice the size of branch leaves, and are triangular with pleats parallel to the strong midrib that reaches at least 3/4 of the way to tip. Leaf edge not toothed but often rolled down. Capsules are very rare, like curved macaroni, 2-3 mm long, with a short-beaked lid. Stalk is 2-3 cm tall.
General Distribution and Habitat
Found on calcium-enriched dry rocks and soils, on sand dunes and the floor of conifer forests.
Found growing in a patch on the stone wall in the recently cleared area behind Jennings, once forested.
