Hymenophyllum malingii (Hook.) Mett.
Vascular - Native
Apteropteris malingii(Hook.) Copel.; Sphaerocionium malingii (Hook.) K. Iwats.; Trichomanes malingii Hook.
Endemic. North and South Islands from Te Moehau and Mt Pirongia south throughout the western parts of the South Island, and also around Dunedin.
Montane to subalpine. Usually on the dead or dying trunks of kaikawaka (Libocedrus bidwillii) but also occasionally found on Hall's totara (Podocarpus cunninghamii), rimu (Dacrydium cupressinum), Halocarpus biformis, beech (Fuscospora and Lophozonia spp.) and on moss covered boulders, rocks and cliff faces
Epiphytic (rarely rupestral) fern forming dense to diffuse pendulous patches. Rhizomes long-creeping, gracile, rather brittle. Stipes 30-100 mm long, thin, brittle, not winged, densely covered in grey-red stellate hairs, rachises not winged. Laminae narrowly ovate or linear, 2-3-pinnate, greyish white to red-brown, 30-200 × 5-30 mm, all parts densely invested by stellate hairs, the adaxially grey and abaxially red-brown. Ultimate segments linear, rigid, tubular (round in cross-section), margins smooth. Sori terminating ultimate segments. Indusial flaps densely hairy.
Easily recognised by its peculiar preference for the trunks of usually dead or dying kaikawaka, narrow, grey-white to red-brown colour, and by the narrow, tubular ultimate segments which are densely covered in grey or red-brown stellate hairs.
