Pyrrosia Mirb.

Sori occupying up to three-quarters of the abaxial surface of the fertile fronds, irregularly but densely crowded in 1–4 rows on each side of the midrib, slightly confluent in age, but retaining their identity longer than the sori of P. confluens. Fronds markedly dimorphic; sterile fronds frequently almost orbicular, 1–2.5 cm (sometimes up to 8cm) long including the stipes, 0.3–1.4 cm broad, often shorter than the fertile fronds. Scales of the rhizome squarrose, entire, thin-textured, pale-ferruginous. Widespread. RF. Usually covering rocks. Rock Felt Fern Pyrrosia rupestris
Sori usually restricted to the extreme distal portions of the fertile fronds as 2 oblong or oval coenosori, occasionally fusing to form a single round patch but rarely a single row of unfused sori on each side of the midrib. Fertile and sterile fronds rather similar, mostly 3–7 cm long including the stipes (but ranging from 1.5–18 cm long), 0.5–1.5 cm broad; sterile fronds never orbicular. Scales of the rhizome appressed, fimbriate, thick, dark chestnut-coloured in the young condition, later dark brown or dark grey-brown or black; border pale, hyaline. Hunter River Valley. RF.
