Rhizome wiry, slender, sparsely clothed with pale, reddish brown hairs. Fronds 6.5–18 cm long, pendulous. Stipes widely spaced, 2–5.5 cm long, to 1 mm diam., winged almost to the base, ±glabrous; wing distinctly crisped except at its base. Lamina oblong-lanceolate, deeply 2–3-pinnatifid, 4.5–13 cm long, 2–5 cm wide; main axis with at least a slightly crisped wing. Ultimate segments 0.8–2 mm wide; margins entire, usually slightly crisped near junctions of the axes and those of lesser order. Sori mostly in the apical one-third of the lamina, borne on apices of lateral ultimate segments; sterile apex of each primary pinna rarely projecting beyond outermost sori of that pinna; involucre round, bilabiate, divided almost to the base, 1.4–2 mm diam.; margins entire or slightly irregular; receptacle included. 

Endemic to QLD between Iron Range CYP and SE Qld.

Terrestrial or among rocks in mesic lowland to upper montane vine forest, usually near creeks.

Often recognised by its very dark bluish green fronds. Named after botanist L.J. Brass who collected the type specimen on Mt Finnegan NEQ.
