Common Fern Moss
Fern Moss family (Thuidiaceae)
Description: This pleurocarpous perennial moss forms a loose mat of evergreen compound leaves that are green to yellowish green and either double-pinnate or triple-pinnate. The central stems of these leaves are up to 8.5 cm. (3½") in length; they are densely covered with narrow scale-like leaves (perichaetial leaves) up to 0.5 mm. in length that are long-ciliate along their middle to lower margins (the cilia resembling hairs). In addition, the larger stem leaves are about 1 mm. in length, broadly ovate to triangular-ovate in shape, smooth and revolute (rolled downward) along their margins, and convex on their outer sides. Under high magnification (40x or more), the outer sides of these leaves appear minutely bumpy (one swelling per leaf cell). The midribs of these leaves extend nearly to their tips. Several leafy primary branches radiate from the central stem of the compound leaf, becoming shorter as they approach the tip of the central stem; these primary branches diverge from the central stem at a 45–90° angle. When they are present, several leafy secondary branches radiate from each primary branch of the compound leaf, becoming shorter as they approach the tip of each primary branch; these secondary branches diverge from each primary branch at a 45–90° angle. The leaves of the primary branches are about 0.5 mm. in length, while the leaves of the secondary branches are about 0.3 mm. in length; they are very similar to the larger leaves of the central stem, except smaller in size. .
