Obs. — Apotliecia sat prominula (altit. mm ,20-0 mui ,25 supra super-

 singulis interdum rimam transversam sistentibus). Apices apotheciorum 

 haud obtusi. Hanc novo-granatensem olim sphaleram dixi, sed vix sicut 

 variâtes est separanda, nec nomen lioc retinui. Maxime accedere videtur 

 ad Gr. chlorocarpam, sed apotliecia albido-obducta, thecaa 8- sporae, sporae
