dense yellowish-green tuft, glossy; stems at the shorter end of what's known for this species at about 2 cm (they grow up to 8 cm); not seen here, but they are indeed densely tomentose with white to reddish brown rhizoids.
Leaves falcate-secund in this case, quite crisped; concave proximally to keeled above; lanceolate, apex acute; margins strongly serrate in the distal part, entire proximally; proximal laminal cells linear-rectangular, pitted; distal laminal cells shorter, sinuose, pitted.
The parichaetal leaves are lacking in this infertile specimen; however, having reviewed all the characters I am positive this is not Dicranum scoparium, with which it might otherwise be confused. Comparing with Dicranum scoparium, the stems of this species are much more tomentose!
The distal laminal cells are also much shorter than D. scoparium.
