Pseudocyphellaria anomala

Pseudocyphellaria anomala is commonly referred to as Netted Specklebelly. The thallus of P. anomala is foliose and loosely appressed to the substrate, though free at the edges. The thallus measures 20 to 40cm across with lobes 1 to 2cm in diameter. The upper surface of the thallus is light to dark brown, typically of the darker brown, with a strong network of ridges while the lower surface is covered with light brown tomentum and scattered psedocyphellae, appearing as white spots. The primary photobiont is blue gree algae. P. anomalahas both asexual and sexual reproductive structures: the soralia are rounded to irregular in shape and whitish-gray or blue gray in color and are located on the upper thallus surface ridges, the apothecia are brown in color and uncommon in formation.

P. anomal commonly uses the bark or deciduous trees and shrubs as a substrate, though will sometimes use conifers and wood structures. Even less commonly, P. anomala will make a home on rock. Habitat preferences of P. anomala include low to mid elevation moist forests, riparian areas, and hardwood forests of the Willamette Valley of Oregon. Mountainous coniferous forests have sporadic occurances of P. anomala.

The geographic distribution stretches between Alaska and California, remaining west of the Cascades. Sightings have been reported east from the Cascade to Montana, though rarely.
