Aptly Named "Sunburst"

Day 19: While a lot of lichens have some rather strange common names (Frog Pelt, Ticker-tape, Volcano, Deflated Tube), the logic behind "Sunburst" is obvious. Its Latin nomenclature reflects its colour and abundant apothecia: Xanthoria polycarpa, i.e., "xanthous" (yellow) and "many-fruited." It occurs farther inland than its cousin X. parietina, a species which in any event is rather rare on the west coast. Look for the apothecial disks which distinguish it from Candelariella vitellina (Common Goldspeck). Sunburst will be found on tree bark, Goldspeck almost always on rock.
