Overview |
|
|||||||
Xanthoria is a very common and very widespread genus of lichenized fungi known as Sunburst Lichens, Orange Lichens, or Orange Wall Lichens. In 1997 there were 15 recognized Xanthoria species. In 2013 some of those species were transferred to the genera Xanthomendoza or Rusavskia. The transfer is relatively recent and is not (yet) universally recognized. Most Xanthoria species grow on trees, but at least one very common species, Xanthoria elegans, grows on rock. Those that grow on trees get all of their nutrients from the air. |

Description |
||
Xanthoria lichens are composed of small, often overlapping scales called squamules. The reproductive structures (apothecia) are raised and plate-like. All Xanthoria lichens contain parietin, an orangish-yellow pigment that absorbs blue light, protects the lichen from damage by UV-B light, and is the source of the common name of the genus. The pigment often darkens when in direct sunlight and lightens when in shadow. |
