Dr. Nylander (in litt.) has determined this lichen as V. aspitea, Ach. 
There is some confusion about Acharuis’s plant. Nylander has remarked, 
“Esse videtur modo V. nitida minor, sporis minoribus.” Montaigne 
describes V. aspitea, Ach., with “sporis magnis ellipticis 16-annulates, an- 
nulis pauci-cellulosis.” He adds that V. aspitea, of Eschw. is incorrectly 
named. He has, therefore, named Eschweilei’s plant V. eschweileri, with 
‘‘spora binucleolata.” Acharius describes his plant as having polished 
yellowish thallus, limited by a black line. In these and other characters 
it differs from the New Zealand lichen.
