Notogrammitis angustifolia subsp. nothofageti
(Parris) ParrisRhizome erect, short, covered with light brown, papery scales. Fronds crowded, erect, 3–13 cm tall, 0.2–0.5 cm wide, firm in texture; stipe very short, winged, hairs absent. Lamina simple, linear-lanceolate, narrow, dull green, margins entire; midvein visible, lateral veins obscure, free. Sori in middle or upper two-thirds of frond, but not reaching apex, oblong, slightly oblique or almost parallel to midvein, 5–20 pairs; spores mostly 34–55 µm diam.
OtP, WPro, HSF, OtR, Strz, VAlp. Epiphytic or lithophytic in wet forest, and usually occurring singly or as a few plants. In the Otway Range it is both lithophytic, and epiphytic on Olearia argophylla. On Wilsons Promontory, the species has been recorded only as occurring on granite (Mt Oberon). In Tasmania, the species never occurs on tree-fern trunks (unlike N. billardierei). It is likely, but not established, that such a relationship between species and substrates occurs also in Victoria.
1 of 2 subspecies occurs in Australia. Subsp. nothofageti has a solitary rather than colonial habit, more erect and slightly smaller fronds, no darkened vein endings, and generally larger spores and sporangia (Parris & Given 1976). It also occurs at higher altitudes, generally between 500 and 1100 m above sea-level (subsp. magellanica is found below 150 m).
