Chemistry : Tenuiorin. Methyl gyrophorate, hopane-7β,22-diol (tr.), hopane-6α,7β,22-triol, 7β-acetoxyhopan-6α,22-diol (tr.), 6α-acetoxyhopan-7β,22-diol (tr.), norstictic (tr.), stictic, cryptostictic (tr.), and constictic acids, pulvinic acid, pulvinic dilactone and calycin.

N: Northland (Radar Bush to N of Whangarei), Auckland (Waitakere Ra.), South Auckland (near Mercer). S: Otago (Routeburn Valley) [map in Galloway (1988a: 241, fig. 122)].

Australasian

Illustration : Galloway (1988a: 239, fig. 121).

Pseudocyphellaria sericeofulva is characterised by: rounded, short, imbricate-crowded rather cochleate lobes, with crenate to pectinate margins that are noticeably yellow-pseudocyphellate; a smooth, or shallowly bullate, distinctly maculate (×10 lens) upper surface with scattered, moderate to dense, pale-fawn or whitish tomentum; a white medulla; a cyanobacterial photobiont; and a pale-buff tomentose lower surface with scattered, conspicuous, yellow pseudocyphellae; it has a chemistry of depsides, depsidones, pigments and hopane triterpenoids.
