Lecanora pulicaris
Crustaceous lichen. Apothecial discs are reddish-brown to black and tend to be flat; they range in size from 0.3 mm to 1.5 mm. The apothecial rim is complete or at times a little lumpy. The thallus will take up a circular growth pattern if unimpeded, reaching a typical diameter of 4 cm. The central area of the thallus is lumpy or areolate with a crazy-paving appearance.
