Chrysothrix candelaris, commonly known as the mustard powder lichen [1] or gold dust lichen, [2] is a species of leprose (powdery) lichen in the family Chrysothricaceae. It typically grows on tree bark , although it has also been recorded growing on rock .
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 ...
Lecanora muralis (Protoparmeliopsis muralis) is a waxy looking, pale yellowish green crustose lichen that usually grows in rosettes radiating from a center filled with disc-like yellowish-tan fruiting bodies . [1] It grows all over the world. [2]
The lichen is composed of two thalli; an initial primary squamulose thallus growing across bark in a scaly, flaking pattern, followed by a secondary fruticose thallus (), with cup shaped podetia (4-10cm tall) bearing terminal ascocarps contained in apothecial structures.
Chrysothrix is a genus of lichen-forming fungi in the family Chrysotrichaceae. [3] They are commonly called gold dust lichens or sulfur dust lichens, [4]: 253 because they are bright yellow to greenish-yellow, sometimes flecked with orange, and composed entirely of powdery soredia. [5] Apothecia are never present in North American specimens. [5]
Lepraria incana is a species of dust lichen in the family Stereocaulaceae.First described scientifically by Johann Jacob Dillenius in 1741, and then formally by Carl Linnaeus in 1753, it is the type species of the genus Lepraria.
Lepraria is a genus of leprose (powdery) crustose lichens that grows on its substrate like patches of granular, caked up, mealy dust grains. [2] [3] Members of the genus are commonly called dust lichens. [3]: 305 [4] [5] The main vegetative body is made of patches of soredia (little balls of algae wrapped in fungus). [3]
Lobaria pulmonaria is a large epiphytic lichen consisting of an ascomycete fungus and a green algal partner living together in a symbiotic relationship with a cyanobacterium—a symbiosis involving members of three kingdoms of organisms.
