Woodsia glabella is a well-marked species occasionally confused with narrow, glabrescent forms of W . alpina and W . oregana subsp. oregana . These taxa are readily distinguished from W . glabella by their petioles, which are reddish brown or dark purple near the base.

Petiole green or straw-colored throughout, articulate above base at swollen node, somewhat pliable and resistant to shattering. Blade linear to linear-lanceolate, pinnate-pinnatifid proximally, glabrous or with occasional sessile glands, never viscid; rachis glabrous. Proximal pinnae fan-shaped, wider than long; distal pinnae ovate-lanceolate, longer than wide, abruptly tapered to a rounded or broadly acute apex; largest pinnae with 1--3 pairs of pinnules, abaxial and adaxial surfaces glabrous. Pinnules entire or broadly crenate; margins nonlustrous, thin, lacking cilia or translucent projections. Vein tips slightly (if at all) enlarged, barely visible adaxially . Indusia of narrow hairlike segments, these uniseriate throughout, composed of cells many times longer than wide, usually surpassing mature sporangia. Spores averaging 39--45 µm. 2 n = 78.
