Cladonia rangiformis is a fruticose lichen with gray to pale gray, repeatedly branched structures that grow from the ground. Its irregular branching can make it resemble reindeer lichens, although it belongs to a different species and has distinct chemical and morphological characters. It is commonl...

Caloplaca aurantia is an orange crustose lichen that grows tightly attached to mineral surfaces, particularly sun-exposed calcareous rock. Its bright orange thallus and fruiting structures help distinguish it from less strongly pigmented crustose lichens, although accurate identification may require...

Diploicia canescens is a foliose lichen with a pale gray to whitish thallus that may look frosted or powdery from a distance. It is distinguished by raised isidia, small outgrowths that serve as vegetative reproductive structures and give parts of the surface a granular or knobbed appearance. The sp...

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

Caloplaca flavescens is a saxicolous, calcicolous lichen in the orange or yellow-orange group of crustose lichens traditionally placed in the genus Caloplaca. It grows on exposed calcareous rock, especially limestone, where its colored thallus and reproductive structures form visible patches. The sp...

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

Caloplaca citrina is a crustose lichen with a bright yellow to orange thallus that can resemble the color of a lemon. It grows on alkaline surfaces, especially calcareous rock, limestone, mortar, and masonry, and is therefore frequently encountered on buildings and other structures in towns and citi...

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...

Diplotomma alboatrum is a crustose lichen with a chalky white, pale gray, ochre, or pale brown thallus that is often cracked or areolate. Its small black apothecia may be covered with a whitish powder and are frequently abundant on the thallus. The species grows on calcareous and siliceous rock, bar...

Cladonia humilis is a small fruticose lichen that grows in compact tufts on the ground. It is identified by short podetia that may form narrow, goblet-like cups, although the shape and openness of these structures can vary among specimens. The species occurs in sandy soils, heathland, and other open...

Endocarpon pusillum is a small squamulose lichen that grows on bare or moss-covered soil and soil over rock. Its brown to ochre squamules are usually attached to a dark basal layer and bear conspicuous black rhizines, while its immersed perithecia produce muriform spores. The species occurs on both...

Candelariella aurella is a yellow crustose lichen in the family Candelariaceae, often known as the hidden goldspeck or egg-yolk lichen. It forms small yellow areoles and apothecia on exposed calcareous rock, calcareous sandstone, or dust-impregnated bark and wood in lime-rich areas. The species is w...

Gyalecta jenensis is a crustose lichen associated with shaded, basic substrates. It forms pale orange to pinkish, wheel-like apothecia that stand above the thallus and have a conspicuous thick margin, giving the fruiting bodies a clustered appearance. The species occurs on basic rock and on old mort...

Aspicilia calcarea is a crustose lichen in the family Hymeneliaceae that grows directly on hard calcareous rock. Its thallus is commonly chalky white to pale blue-grey, with a smooth or cracked-areolate surface and radial cracking toward the margins. Black or initially grey-pruinose apothecia are im...

Aspicilia contorta is a saxicolous, calcicolous crustose lichen associated with limestone, other basic rocks, and mortar. Its pale thallus is divided into angular areoles by conspicuous fissures, giving the surface a cracked appearance. The species can colonize masonry and stonework, particularly in...

Sarcogyne regularis is a crustose lichen noted for its reddish-brown, often immersed apothecia on acidic rocks, first described by German botanist Gustav Wilhelm Körber in 1860.

Verrucaria nigrescens is a crustose lichen, meaning that its thallus grows tightly attached to the surface it colonizes. It commonly forms a dark to black, areolate or cracked-looking crust on calcareous rock, including limestone and man-made stone. The species is saxicolous and calcicolous, so it i...

Staurothele fissa is a species of crustose, rock-dwelling lichen in the family Verrucariaceae. It is especially associated with wet or periodically submerged siliceous rocks in streams and rivers, where its thin brown to greenish-brown thallus may be cracked or areolate. The species forms immersed o...

Verrucaria baldensis is a lichen-forming fungus associated with bare limestone and other calcareous rock surfaces. Descriptions emphasize its crust-like growth and immersed perithecia, the dark reproductive structures that can appear as rounded pits or discs in the rock. The name is also treated in...

Rinodina teichophila is a crustose lichen-forming fungus in the family Physciaceae. It grows on rock, including acidic and weakly calcareous stone, and is often found on walls and memorials rather than only in natural habitats. Its thallus is thick, rough, and gray to black, while the immersed to at...

Polyblastia cupularis is a species of lichenized fungus in the genus Polyblastia and the family Verrucariaceae.
