Descriptions : Flora (1985: 444). See also Galloway (1998a: 152–154).

Chemistry : hopane 6α,7β,22-triol, 6α-acetoxyhopan-7β–22-diol (minor), 7β-acetoxyhopan-6α,22-diol (tr.), hopane-7β,22-diol (minor), hopane-15α,22-diol (tr.), 7β-acetoxyhopan-22-ol (tr.), methyl virensate, physciosoporin (major), stictic, constictic, norstictic (tr.), and cryptostictic (tr.) acids.

N: Northland (Bay of Islands) to Cook Strait. S: Nelson to Southland, both E and W of the Main Divide. St: (N coast to Port Pegasus) [map in Galloway (1988a: 155, fig. 73)]. An epiphyte of lowland coastal forest and scrub trees and shrubs and often common on Fuchsia and Leptospermum; also on rocks in tussock grassland and on dead stumps, s.l. to 1000 m. Known also from E Australia and Tasmania and southern South America (Galloway 1992c; Galloway & Quilhot 1999; Galloway et al. 2001b; McCarthy 2003c, 2006).

Pseudocyphellaria granulata is characterised by: deeply incised, linear-elongate to broadly rounded lobes with irregular, ragged or incised-crenulate, sorediate-eroded margins; a plane to punctate-impressed to faveolate upper surface with erumpent, pustulate soralia on lamina or on ridges; a white medulla; a green photobiont; a uniformly black lower surface or glabrous marginally, and with scattered white pseudocyphellae; sessile to pedicellate, rather rare apothecia, the disc black, coarsely white-pruinose at first; a smoky grey to olive-brown epithecium turning purple-violet in K; and a complex chemistry of hopane triterpenoids and stictic acid metabolites with physciosporin as a characteristic component.
