Description : Flora (1985: 30)
N: S: Throughout. On Cordyline, Griselinia, Hoheria and other trees, forming mosaics on smooth bark, delimited by a narrow, irregular prothallus, often among epiphytic mosses and ferns and often overgrowing these, lowland and coastal. Known also from Great Britain, Europe, Scandinavia (Vainio 1922: 175–176; Purvis et al. 1992; Nimis 1993; Santesson 1993; Llop & Hladun 2002; Nimis & Martellos 2003; Santesson et al. 2004).
