Nodobryoria abbreviata, the tufted foxtail lichen, is a species of fruticose lichen in the family Parmeliaceae. It was originally classified as a form of Alectoria in 1889, then moved to the genus Bryoria, before being transferred to the newly created genus Nodobryoria in 1995 based on distinctive anatomical and chemical differences. The lichen grows throughout western North America, from British Columbia south to Baja California, typically found on conifer bark and dead wood in forests from valley bottoms to near the tree line. It is most common in the interior Pacific Northwest, especially

Schaereria porpidioides is a species of saxicolous (rock-dwelling), crustose lichen in the family Schaereriaceae. It is found in the Falkland Islands.

Nodobryoria is a genus of medium to large, reddish-brown lichens that are hair-like to shrubby (fruticose) in shape and grow on conifer trees. The genus contains three species, distributed in North America and Greenland, which were previously included in the genus Bryoria. Nodobryoria is similar in appearance to Bryoria, but is differentiated because it does not contain the polysaccharide lichenin (which is present in high quantities in Bryoria), and it has a unique cortex composed of interlocking cells that look like pieces of a jigsaw puzzle when viewed under a light microscope.

Phaeographis delicatula is a species of crustose lichen in the family Graphidaceae. It is known from subtropical Florida and Brazil, where it grows on the branches of hardwoods. It is characterized by delicate lirellae (slit-like fruiting bodies) in dense clusters that often branch in a star-like pattern. Chemically, its main lichen substance is stictic acid.

Halegrapha floridana is a species of script lichen in the family Graphidaceae. It forms a thin, yellowish-white crust on tree bark and produces black, elongated, slit-like fruiting bodies. The species is known only from an old-growth cypress swamp in southern Florida.

Fissurina varieseptata is a species of crustose lichen in the family Graphidaceae. It is known from Florida. It has small, fissure-like lirellae (slit-like fruiting structures) and ascospores that usually have 5–7 transverse septa (internal walls), rather than the more typical three in closely similar species.

Fissurina tuckermaniana is a lichen that forms a thin, crust-like growth on bark and belongs to the family Graphidaceae. It is known from subtropical Florida. It has fissure-like, darkened lirellae (slit-like fruiting structures) and unusually large ascospores with three septa, produced in low numbers in each ascus. It also has spinulose (spiny-tipped) paraphyses and periphysoids.

Fissurina inspersa is a species of crustose lichen in the family Graphidaceae. It was first described from collections made in Florida. It has fissure-like lirellae (slit-like fruiting structures) and a strongly inspersed hymenium (the spore-producing layer, filled with tiny droplets that cloud the view under the microscope), and it produces stictic acid as its main secondary metabolite.

Fissurina confusa is a lichen that forms a thin, crust-like growth on bark and belongs to the family Graphidaceae. It was first described from collections made in Florida. It is distinguished by prominent, lip-like lirellae (slit-like fruiting structures), muriform ascospores (divided into many small compartments), and thallus chemistry dominated by psoromic acid.

Fissurina analphabetica is a species of crustose lichen in the family Graphidaceae. It was first described from collections made in Florida. It has extremely small, fissure-like lirellae (slit-like fruiting structures), and standard chemical screening (thin-layer chromatography) did not detect any lichen substances.

Fissurina aggregatula is a lichen that forms a thin, crust-like growth on bark and belongs to the family Graphidaceae. It was first described from Fakahatchee Strand Preserve State Park in southwestern Florida. There, it forms small clusters of short lirellae (slit-like fruiting structures), and standard chemical tests (thin-layer chromatography) did not detect any lichen substances.

Tapellaria floridensis is a species of crustose lichen in the family Ectolechiaceae. It is known from subtropical Florida and has black apothecia (disk-like fruiting bodies) with margins that are often conspicuously gray and dusted with pruina, especially when young.

Graphis appendiculata is a species of bark-dwelling crustose lichen in the family Graphidaceae. It is known from subtropical Florida. It forms a pale, smooth thallus with dark, finely grooved lirellae (slit-like fruiting structures) that often narrow abruptly toward the ends.

Fissurina subcomparimuralis is a species of lichen-forming fungus in the family Graphidaceae. The species was formally described in 2014 after being distinguished from the closely related F. comparimuralis by differences in spore characteristics and microscopic structures. It forms thin, yellowish-brown to olive-brown crusts on tree bark with elongated fissures that break through the surface. Originally known only from Florida's Everglades region, it has since been found in China as well.

Calopadia imshaugii is a species of crustose lichen in the family Ectolechiaceae. It was described from Florida. It has brown apothecia (fruiting bodies) with a coarse, white pruinose (powdery) coating, and its muriform (multi-chambered) ascospores are often produced two per ascus (sometimes one or three), which is unusual in Calopadia.

Hemigrapha graphidicola is a species of fungus in the family Hemigraphaceae. It is a lichenicolous fungus that grows on the thallus of the script lichen Graphis assimilis and has only been collected in Fakahatchee Strand Preserve State Park in Florida. This state park is located in the Florida Everglades, which makes Hemigrapha graphidicola a mangrove species. It is identifiable by its black, superficial, flat, roundish to elongate or irregular form. Hemigrapha species are very similar, so Hemigrapha graphidicola should be identified under a microscope. Hemigrapha graphidicola is unique

Amerosporiopsis phaeographidis is a species of lichenicolous fungus in the subphylum Pezizomycotina. It grows as black spots on the lichen Phaeographis brasiliensis, from which it gets its name. It has only been found in one place in the Fakahatchee Strand Preserve State Park in Florida in the United States. Molecular phylogenetics testing might reveal that this is actually a new genus, but it is morphologically similar to the one other species in Amerosporiopsis, except that it has wider conidia, has no conidiophores, and lives in a different habitat.
