A lichen with brown to orange areoles, sometimes up to 6 mm wide, bearing numerous punctiform apothecia (sometimes up to 100 on the largest areoles). The hymenium is usually taller than 180 μm, pale orange to almost brown in shaded specimens.
Myriospora tangerina occurs in Europe and North America. It is primarily a montane species of natural, metal-rich rocks. It prefers vertical to overhanging surfaces. In the Czech Republic the lichen is a rather rare species, so far known only from the Krkonoše Mountains (Obří důl), the Hrubý Jeseník Mountains, Drbákov–Albertovy skály and from the vicinity of Střezimíř in Central Bohemia.
