Graphis scripta is a crustose lichen in the family Graphidaceae. It is commonly called script lichen, secret writing lichen, or similar names, because its growth pattern makes it looks like writing. [1] [2] Stigmidium microspilum and Arthonia graphidicola are associated lichenicolous fungi. [2] It is variable with either curved or stellate ...
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 ...
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 .
Sulcaria isidiifera, commonly known as the splitting yarn lichen, is a rare species of pendent (hanging) fruticose lichen in the family Parmeliaceae. [1] It has a dull yellowish-white to light brown and reddish-brown thallus and is typically 3–5 cm (1.2–2.0 in) long.
Ramalina menziesii, the lace lichen or fishnet, is a pale yellowish-green to grayish-green fruticose lichen. It grows up to a meter long, hanging from bark and twigs in a distinctive net-like or lace-like pattern that is unlike any other lichen in North America. [3] It becomes a deeper green when wet. [3] Apothecia are lecanorine. [3]
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.
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]
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]
