Description : Flora (1985: 534 – as Sphaerophorus notatus). See also Tibell (1985: 201–202; 1987: 239 – as Sphaerophorus notatus), Wedin (1995b: 67–69; 2001a: 9).
Chemistry : Medulla K+ pale-yellow or −, Pd−; containing isousnic acid (major), stictic acid (minor, or tr. in apothecia), constictic acid (minor or tr. in apothecia), placodiolic acid (tr.) "UN-notatus" (tr.). The stictic acid components appear to be produced only in the apothecia (Tibell 1987; Wedin 1995b, 2001a: 9)
N: South Auckland (Te Aroha) to Wellington (Tararua Ra.). S: Nelson (St Arnaud Ra.) to Southland (Pourakino Valley). In mixed podocarp-broadleaf, and beech forests. Also in E Australia and Tasmania (Wedin 1995b, 20012a: 9; McCarthy 2003c, 2006).

Illustrations : Tibell (1984b: 635, fig. 18D, E; 1985: 202, fig. 5; 1987: 240, fig. 179 – as Sphaerophorus notatus); Wedin (1995b: 68, fig. 30).
Bunodophoron notatum is characterised by: the corticolous habit; the terete, slender branches, the tufted habit and the gradually widening thalline receptacle. The combination of isousnic acid in the cortex, the lack of sphaerophorin and the large, brownish spores are also distinctive. It sometimes resembles B. ramuliferum, but that species has a usually distinct coralloid branching pattern, has smaller, grey spores and contains sphaerophorin.
