N: Northland (Three Kings Is), Auckland (Rangitoto I.). S: Otago (Alexandra, Port Chalmers). Coastal and inland, on rock. Known also from South Africa and Australia (Esslinger 1977b: 154; Elix 1994k: 85; Kantvilas et al. 2002; McCarthy 2003c, 2006).

Illustration : Elix (1994k: 83, fig. 43D – as Neofuscelia verrucella).

Xanthoparmelia verrucella is similar to X. loxodella but differs in medullary chemistry (X. loxodella has glomelliferic and glomellic acids). Both taxa are sympatric in Australasia but X. loxodella is apparently the more common (Culberson et al. 1977). X. verrucella is characterised by: the loosely to moderately adnate thallus, the black lower surface, the cylindrical isidia, and divaricatic acid in the medulla.
