Holotype: New Zealand. South I. Canterbury, Banks Peninsula below summit of Mt Sinclair, 670 m, on rocks on forest floor in dense bush, 14.ii.1980, J.A. Elix s.n. – CHR 381117.

Stictina fragillima var. myrioloba. Holotype: New Zealand. Sine loco, Charles Knight 323 – G.

Descriptions : Flora (1985: 442–443). See also Galloway (1988a: 142–144).

Chemistry : 7β-acetoxyhopane-22-ol, hopane-7β, 22-diol (tr.), hopane-15α,22-diol.

N: South Auckland (Coromandel Peninsula) to Cook Strait. S: Nelson to Southland [map in Galloway (1988a: 145, fig. 67)]. Both E and W of the Main Divide, s.l. to 1200 m. It is a shade-loving species and is most commonly collected from low-light, moist, cool habitats on the forest floor (both rocks and soil), at the base of tree trunks and on tree roots deep in the forest interior, or along streambeds. It grows also on damp soil, on shaded rock faces, and can even withstand periodic inundation on streambed boulders.

Illustration : Galloway (1988a: 143, fig. 66).

Pseudocyphellaria fimbriatoides is characterised by: rather variable though generally broad lobes with conspicuously phyllidiate margins; phyllidia with glistening white marginal hairs; a coriaceous, often glossy upper surface (reminiscent of Peltigera), and minutely white-papillate; a white medulla; a cyanobacterial photobiont; a lower surface that is glabrous marginally and pale- to dark-brown tomentose centrally with scattered white pseudocyphellae; and a two-hopane chemistry.
