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 .
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 ...
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]
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.
It was in 1869 that Simon Schwendener demonstrated that all lichens were the result of fungal attack on the cells of algal cells and that all these algae also exist free in nature. This researcher was the first to recognise the dual nature of lichens as a result of the capture of the algal component by the fungal component. [ 19 ]
The cross-taxon analysis approach has shown that lichen abundance and diversity significantly influence the diversity patterns of lichenicolous fungi. This method has demonstrated that lichen communities can serve as reliable surrogates for predicting lichenicolous fungal diversity, aiding in the conservation and study of these specialised fungi.
