Discussion
Cirriphyllum piliferum is easy to recognize by its rather large size, usually pure green and somewhat whitish color, and regular pinnate branching. The concave-inflated and closely imbricate distal leaves are abruptly contracted into filiform acumens, resulting in a peculiar appearance when they stand at a sharp, broad angle from the upper shoot (when wet, as usually occurs in the field). When a shoot is examined against a dark background, the acumens are usually easily visible, allowing for ready field identification. Brachythecium (Cirriphyllum) cirrosum differs from C. piliferum by its more abruptly contracted, so more strongly piliferous, leaves, and branch leaves that do not much differ from stem leaves (in C. piliferum, the branch leaves are not or at least less strongly piliferous); the irregular branching (fairly regular in C. piliferum); the usual yellow color of the plants (usually green in C. piliferum); and rather small alar cells (enlarged in C. piliferum).
