Descriptions : Flora (1985: 453 – as Pseudocyphellaria murrayi; 457). See also Galloway (1988a: 204–205 – as P. murrayi; 235–237).

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

N: Northland (lat. 35ºS) to Cook Strait. S: Nelson to Southland both E and W of the Main Divide. St: (N coast to Port Pegasus), A: [map in Galloway (1988a: 238, fig. 120)]. Lowland to subalpine, s.l. to 1200 m. An epiphyte of tree trunks, and twigs and branches of small trees and shrubs and on rotting logs. Mainly a lowland species, it reaches a great size in cool, humid habitats in partial shade. In full sunlight, specimens are often suffused brownish. It is most common in podocarp forests or forest remnants, along streams, and in disturbed sites where Leptospermum is common.

Pseudocyphellaria rufovirescens is characterised by: linear-elongate, dichotomously branching lobes with truncate or shallowly furcate, divergent apices, and entire, ridged margins; a shallowly faveolate upper surface, the interconnecting ridges broad and rounded and developed fully across the lobes; a white medulla; a green algal or a cyanobacterial photobiont; a pale or white, bullate, lower surface which is glabrous or occasionally sparsely tomentose, and with scattered, minute, white fleck-like pseudocyphellae; sessile, marginal apothecia, the disc pale red-brown, epruinose; and a two-hopane chemistry. It may be parasitised by the lichenicolous fungi * Arthonia fuscopurpurea, * Dactylospora lobariella, *Stigmidium peltideae and * S. schaereri (q.v.).
