Lepraria ecorticata (J.R.Launon) Kukwa
(= Lecanora ecorticata J.R.Laundon)
Thallus diffuse, thin to rather thick and cracked, powdery (leprose), lacking a medulla or any marginal differentiation into lobes, pale yellow-green (said to be bluish grey in deep shade), granules without projecting hyphae, thallus K-; apothecia unknown. In shaded places on acid rocks, probably frequent in western Britain, but first described as a species in 2003 and undoubtedly under-recorded.
Refs: Smith et al. (2009), 537; Dobson (2011), 248 (photo).
This species resembles Psilolechia lucida, which is a somewhat brighter, sulphur yellow. Lecanora orosthea is also similar, but the thallus is corticate, at least when young, the cortex likely to persist at least at the margins.
