Menegazzia foraminulosa is distinguished from other species in the genus by having ochre-yellow pigmentation of the tomentum on the upper side of the internal cavity; stictic and echinocarpic acids and pigments in the medulla; 8-spored asci; and swollen, pigmented apical cells in the paraphyses. The faintly white-maculate lobe ends that are ±flattened are also characteristic for the species. M. caliginosa is its sorediate counterpart.
