It has the relatively broad thallus, the 3-angled branches, the dilated branching node-like areas ( plant stem ), and the wide spreading terminal branches that characterizes the species, but unlike the Channel Island specimens, its longitudinal ridges are more sharply angled, and the subterminal apothecia have extended branches as seen in " N . disrupta ".

This so-called silver chromate impregnation procedure stains entirely or partially the cell bodies and neurites of some neurons-dendrites, axon-in brown and black, allowing researchers to trace their paths up to their thinnest terminal branches in a slice of nervous tissue, thanks to the transparency consequent to the lack of staining in the majority of surrounding cells.

The species ( " N . suffnessii " ) is further distinguished by the relatively thin cortex, 35 75 (-100 ) �m thick, which is typically smooth with longitudinal ridges coinciding with the branch margins, occasionally twisting up the branch, appearing more prominently reticulate on terminal branches, or in other thalli, the cortical ridges conspicuous from near base.
