Hypogymnia physodes is a foliose lichen commonly called the tube lichen or puffed lichen. Its gray to gray-green thallus has inflated, hollow lobes that often form loose branching tufts, and its lower surface is typically dark. The species grows epiphytically on tree bark and can also occur on wood...

Lobaria virens, also treated in modern references as Ricasolia virens, is a large foliose lichen with leafy lobes that can appear vivid green when wet and darker when dry. It grows mainly on the bark of broad-leaved trees in shaded, sheltered, humid woodlands, and it can also occur on protected rock...

Peltigera aphthosa is a large terrestrial foliose lichen with broad lobes and wart-like cephalodia on the upper surface. The cephalodia contain cyanobacteria, allowing the lichen to obtain nitrogen through biological fixation in addition to the photosynthesis provided by its primary algal partner. I...

Parmelia saxatilis is a foliose lichen commonly known as crottle or salted shield lichen. It has gray, leaf-like lobes with a network of raised ridges and often grows attached to rocks, tree bark, and other exposed surfaces. The species has been used historically as a source of lichen dye, especiall...

Pseudocyphellaria intricata is a foliose lichen in a group that commonly forms broad, leafy lobes and houses cyanobacteria as its primary photosynthetic partner. The species is associated with humid, oceanic forests, where it grows on bark, moss, or other damp surfaces and may occur in old, relative...

Umbilicaria pustulata is a foliose lichen in the rock-tripe group, attached to exposed stone by a central holdfast rather than across its entire lower surface. Its brownish to gray thallus has blister-like pustules and broad lobes, and it occurs on rocks in mountainous, boreal, and other cool or ope...

Menegazzia terebrata is a foliose lichen recognized by lobes pierced by conspicuous round holes, a feature reflected in the common name hole lichen.
