N: Northland (lat 35 ºS) S to Cook Strait. S: NW Nelson to Southland. St: SN: Ch.: Ant.: A: C: Widespread [map in Galloway (1988a: 151, fig. 71)], coastal to alpine, s.l. to 2000 m. It has the widest range and ecological tolerance of any species of Pseudocyphellaria in New Zealand, being known from all forest types, coastal and subalpine scrub, subalpine to high-alpine grassland and herbfield. It grows luxuriantly in the wettest areas of the country, in forests W of the Main Divide and especially in Fiordland, and it is also found in the very driest areas as well, in Central Otago and eastern parts of South I. It is known also from E Australia, Tasmania, Lord Howe I., Macquarie I., and southern South America (Galloway 1992c; Galloway & Quilhot 1999; Galloway et al. 2001b; McCarthy 2003c, 2006).

Pseudocyphellaria glabra is characterised by: narrowly laciniate to broadly imbricate-complex lobes with entire, sinuous to crenulate or incised and often isidiate margins; an undulate, glossy, shallowly wrinkled but never faveolate upper surface; laminal and marginal, terete isidia; a white medulla; a green photobiont; a pale- to dark-brown or black lower surface with prominent white pseudocyphellae; a two-hopane chemistry with stictic acid metabolites and usnic acid that confers a yellow-green colour to the the upper surface, especially in habitats exposed to full sunlight. It may be parasitised by the lichenicolous fungi * Arthonia maculiformis, * A. pseudocyphellariae, * Perigrapha nitida and * Plectocarpon pseudosticta (q.v.).
