Wooly Feather Moss,
MNPS Threat Rank
Plant: Pleurocarpous (Vitt 1988). Erect and tufted or scattered with other mosses. Glossy, yellow-green to brown below; sometimes with green tips. Stems 5-15 cm tall, branching irregularly. Rhizoids often clustered and can arise from the base of leaves or back of costa.
Leaf: Leaves erect to erect-spreading, elongate-lanceolate (rarely slightly falcate), deeply plicate. Stem leaves 3-4 x 0.7-0.9 mm and branch leaves smaller. Apex gradually acuminate to long and narrow. Margins entire to nearly entire. Costa ends before the apex, 3/4 to 4/5 the length of leaf, and has no spines.
Leaf Cells: A few rows of basal cells are shorter, wider, and more pitted than the median cells. Median leaf cells are 50-90 x 5-6 µm, thick-walled, long, and narrow. Alar cells are like the basal cells and do not form a distinct group.
Capsules ripen early to mid summer (FNA 2014).
