Teloschistes chrysophthalmus, sometimes referred to as the gold-eye lichen or golden-eye, is a fruticose lichen with branching lobes. Their sexual structures, apothecia , are bright-orange with spiny projections ( cilia ) situated around the rim.
Polycauliona coralloides, the coral firedot lichen, is a species of small fruticose (bushy), saxicolous (rock-dwelling) lichen in the family Teloschistaceae. [2] First formally described in 1866, it was later shuffled to a few different genera in its taxonomic history before ending up in Polycauliona, a genus resurrected from taxonomic obscurity in the molecular phylogenetics era.
Peltigera rufescens, commonly known as the field dog lichen or field pelt, is a species of terricolous (ground-dwelling), foliose lichen in the family Peltigeraceae. This common and widespread species has a cosmopolitan distribution , often found in dry, sunny habitats on basic soils , limestone , and nutrient-rich silicate substrates.
Peltigera praetextata, or the scaly dog pelt lichen, is a foliose lichen native to North America, Europe, and Asia. [1] It is defined by small belly-button-like growths called phyllidia on its edges and centre.
With the exception of calicioid lichens, lichen growth forms are based on the appearance of the thallus, which is the vegetative (non-reproductive) part of the lichen. [5] In most species, this form is determined by the lichen's fungal partner, though in a small number, it is instead the alga or cyanobacteria (the lichen's photosynthetic ...
Lichenicolous lichens are relatively common; a study in Italy found that 189 of 3005 lichenised species (about 6%) were lichenicolous. [19] These lichens show distinct biological and ecological characteristics. They are predominantly crustose, mostly have green, non-trentepohlioid algae as photobionts, and primarily reproduce sexually.
The upper surface of the lobes, which generally measure 10–25 mm (0.4–1.0 in) across, have a fuzzy tomentum, especially near the margins. The lichen typically grows on soil, in woodlands, fields, and sandy areas [3] The cyanobiont Nostoc associates with Peltigera canina, and resembles the species N. sphaericum and N. punctiforme. [4]
This category includes the native lichens of the Southeastern United States, within the United States, in North America. Taxa of the lowest rank are always included ...
