The apothecia on these rosette forming Xanthoria elegans are so dense here (also because of the focus of this picture), that there is only one place here where you can clearly see the radiating lobes of the foliose thallus. A common but typically incredibly picturesque lichen that always grows on rocks that are nitrogen enriched and that are completely exposed to the sun. They lack soredia. April 20, 2010, Wasatch Front, Mt. Olympus foothills, Salt Lake County, Utah, between 4,920 to 4,970 ft. elev. West-facing slope, growing on quartzite of the very old Big Cottonwood Formation.

Summary[edit] Description: Lichenoconium xanthoriae M.S. Christ. Image location: Heber City, Utah, USA Small raised darkly colored, spherical fruiting bodies located on hymenial surface of Xanthoria elegans apothecia. Host lichen is located on side of concrete wall, exposed to direct sunlight and next to main highway. Fruiting bodies of lichenicolous fungus appear to develop central depression making some cup shaped, though most are simply rounded domes on the surface of the host lichen. Many Xanthoria elegans thalli were present on the concrete, but only a small area of 6 cm held two infected thalli. It looks visually similar to Leichenoconium species based on pictures I have viewed from the internet, but this is just a guess not based on any microscopic analysis as of yet.
