Description : Flora (1985: 310 – as Neofuscelia subhosseana).
Chemistry : Cortex K−, HNO3+ dark blue-green; medulla K+ yellow→red, C−, Pd+ pale-orange, UV−; containing four unidentified compounds similar to stictic and norstictic acids.
S: Otago (Butchers Dam near Alexandra). Alpine to subalpine on rock. Known also from Europe, North America, Lesotho, Argentina and Chile (Esslinger 1977b: 149; 2002b: 295; Goward et al. 1994b; Galloway & Quilhot 1999; Brodo et al. 2001; Adler & Calvelo 2002).
Bipolar
Illustrations : Goward et al. (1994b: 84, fig. 2B); Brodo et al. (2001: 451, pl. 522) – as Neofuscelia subhosseana.
Xanthoparmelia subhosseana is distinguished by: the saxicolous habit; the pustulate isidia and the characteristic medullary spot test reactions. X. waiporiensis also has pustulate isidia but is K−, Pd−. The species is often sympatric with the non-isidiate X. squamans.
