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 ...
The Cladoniaceae are a family of lichen-forming fungi in the order Lecanorales, comprising about 560 species distributed amongst 18 genera.This family is one of the largest among lichen-forming fungi and is globally distributed, from Arctic tundra to tropical rainforests, favouring humid environments while being intolerant of arid conditions.
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]
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.
Rhizocarpon geographicum (the map lichen) is a species of lichen, which grows on rocks in mountainous areas of low air pollution. Each lichen is a flat patch bordered by a black line of fungal hyphae. These patches grow adjacent to each other, leading to the appearance of a map or a patchwork field.
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.
