Taxonomic research has recognised that the New Zealand specimens considered to be Pseudocyphellaria crocata are, in fact, distinct from them. Molecular studies have shown that the presumably widespread and common New Zealand lichen Pseudocyphellaria crocata is now considered to represent at least four species, all endemic, with the recognition that P. crocata sens. str. itself is not present in New Zealand (Lücking & Moncada 2018; Moncada et al. unpubl. data.) not present in New Zealand (Lücking & Moncada 2018; Moncada et al. unpubl. data.

Pseudocyphellaria crocata (L.) Vain.

Thallus 5-7(-10) cm diam., rigid, lobate, attached centrally, margins mainly free. Lobes ± broadly rounded to deeply laciniate, margins partly imbricate, apices rounded or incised, crenulate to sinuous, often subascendent, not isidiate or phyllidiate. Upper surface pale brownish-yellow with greenish tint, to red-brown or dark chocolate brown, ± densely reticulate-faveolate, ridges strongly defined, lacunae deep or shallow, shining, ridges with ± numerous low warts bursting into yellow soredia, often confluent and spreading, usually smaller or lacking at margins. Medulla white. Photobiont blue-green. Lower surface densely tomentose to margins, pale ochraceous-buff at margins, dark brown to blackish centrally, sometimes margins ± reticulate with yellowish-buff ridges and bullae visible. Pseudocyphellae yellow, scattered, sparse to ± frequent, 0.2-0.4 mm diam., ± sunk in tomentum, punctiform near margins. Apothecia rare, 1-2 mm wide, sessile on ridges, disc deep red-brown or blackish, occasionally faintly pruinose, concave to plane, margins thin, pale reddish-brown, ± smooth to wrinkled. Ascospores 1-septate, (18-)22-30 × 5-9(-12) µm. Chemistry: Pulvinic lactone, pulvinic acid, calycin, methyl virensate, 5-chloromethyl-virensate, hopane-6α, 7β-triol, norstictic, constictic and stictic acids. In c. one fifth of specimens examined stictic acid is replaced by salazinic acid (cf. ).
