Trichomanes
Involucre narrow, elongate, not flared at apex (or only weakly so), 2.3 × 1.3 mm; sporangial receptacle 3-15 mm long; laminar margins with simple trichomes, though these sporadic; stipe narrowly and often inconspicuously alate, generally only in upper ½; stipe to 10 cm long, blade to 18 cm long; laminar indumentum sparse, more abundant on basal portion of abaxial rachis; hairs long, single-celled atop a distinctly bulbous basal cell, these sometimes dark, hairs occasionally multi-celled, rarely clavate; rachis wings generally equal to or less than the width of rachis

Trichomanes
Involucre conic, widely flared at apex, 1.5 × 1.3 mm; sporangial receptacle 2-4 mm long; laminar margins glabrous, rarely with minute, clavate trichomes; stipe alate throughout, this conspicuous in upper ½ (to 2 mm long); stipe to 1.5 cm long; blade to 6.5 cm long; laminar indumentum sparse throughout; hairs miniscule if single-celled, often 2-celled with clavate distal cell, or 3-4 celled, these acicular with all cells similar, never atop a distinctly bulbous basal cell; rachis wings generally twice the width of rachis
