Discussion
Abietinella abietina is the easiest of the Thuidium-like plants to recognize in the flora area, in part because of its distinctive habitat requirements. The stems are 1-pinnate, erect-ascending, and often occur in extensive, lax mats. Paraphyllia are abundant on stems and branches, but are usually not nearly as strongly branched as in Thuidium in the narrow sense. Abietinella abietina is widespread throughout the northern part of the flora. The capsules of this species are very rare. Unlike Thuidium, Abietinella is papillose on both leaf surfaces rather than just the back.
