It is associated with humid tropical or subtropical forests and commonly grows on mossy bark, tree trunks, or other shaded substrates. Its broad, deepl...

Solorina crocea is a foliose lichen with a conspicuously orange lower surface. It commonly grows on exposed, acidic soils in alpine and Arctic environments, where its thallus is associated with cyanobacteria. The species is relevant to lichen studies focused on cold-region and nutrient-poor habitats...

Peltigera canina, commonly called dog lichen, is a large foliose lichen that grows on soil, moss, and other ground surfaces. Its broad lobes are typically grey-brown and felted, with a pale underside and prominent veins. The lichen forms a symbiotic association with cyanobacteria, which can fix atmo...

Leptogium cyanescens is a foliose jelly lichen with bluish-gray, wrinkled lobes. Its thallus becomes gelatinous when wet, a characteristic associated with its partnership with cyanobacteria. The species was described by William Nylander in 1856 and is relevant to studies of cyanolichens on bark and...

Peltigera polydactylon is a foliose lichen that commonly grows on soil, moss, or other ground substrates in damp woodland and other moist habitats. Its thallus forms broad lobes, often with narrower, finger-like extensions, and the species has a cyanobacterium as its primary photosynthetic partner....

Nephroma resupinatum is a foliose lichen that usually grows on bark, moss, or other organic surfaces in humid forests. Its leafy lobes and kidney-shaped appearance are characteristic of the genus Nephroma, while its cyanobacterial photobiont allows the lichen to participate in nitrogen fixation. It...

Pannaria rubiginosa is a foliose cyanolichen with brown to rust-colored lobes that often form small leafy patches over moss, bark, or other damp organic surfaces. Like other Pannaria species, it contains a cyanobacterium as a photosynthetic partner and is associated with humid habitats. It is of int...

Peltigera membranacea is a foliose lichen that usually grows on soil, moss, humus, and other moist ground substrates in temperate regions. Its thallus consists of broad, thin lobes with a somewhat membranous texture, and the species has a cyanobacterium as its principal photosynthetic partner. It is...

Parmeliella triptophylla is a small foliose lichen that contains cyanobacteria as its photosynthetic partner. It forms delicate, divided lobes and is associated with moss-covered bark, decaying wood, and other humid substrates in woodland habitats. Because its thallus is small and closely integrated...

Solorina saccata is a distinctive foliose lichen characterized by its large lower apothecia, typically found growing directly on mossy limestone and calcareous soils.

Leptogium saturninum is a foliose lichen containing cyanobacteria and is often described as a jelly lichen because its thallus becomes more flexible and gelatinous when wet. It forms broad, dark gray-brown lobes with a textured surface and grows on bark, moss, or other humid woodland substrates. The...

Lichina pygmaea is a small fruticose lichen that grows on rocks in the marine splash zone. Its dark brown to black thallus forms compact tufts and is adapted to repeated wetting by seawater, drying, and exposure to wave spray. The species contains cyanobacteria and occupies a coastal niche where few...

Peltigera neckeri is a foliose cyanolichen commonly known as the studded leather lichen. It forms broad, leathery lobes on soil, moss, or other ground-level substrates and contains cyanobacteria that contribute to its photosynthesis. Dark cephalodia or wart-like structures help distinguish it from s...

Placynthium nigrum is a distinctive cyanolichen recognized by its black, radiating rosettes of crinkled lobes, commonly found colonizing damp, calcareous rocks and stonework.

Leptogium lichenoides is a foliose jelly lichen recognized by its blue-gray, minutely ridged lobes and gelatinous texture when wet, commonly found on mossy soil and rocks.

Lichina confinis is a shrubby, dark fruticose lichen that plays a crucial ecological role as a primary colonizer in the coastal supralittoral zone across the Atlantic.

Peccania coralloides is a small lichen in the genus Peccania, a group of lichens associated with cyanobacteria as their photosynthetic partner. It is recognizable by its dark, coralloid growth form, in which short branches or lobes form a compact cushion-like thallus. The species is associated with...

Collema flaccidum is a foliose jelly lichen containing a cyanobacterial partner.

The species grows in damp habitats, including mossy rocks, humid bark, and the bases of trees....

Leptogium gelatinosum is a foliose jelly lichen with a cyanobacterial photosynthetic partner.
