Fauriea is a genus of lichen-forming fungi in the family Teloschistaceae. The genus, which contains seven species, is a member of the subfamily Caloplacoideae. Characteristics of the genus Fauriea include its crustose, continuous grey to whitish-grey thallus and Lecanora-type apothecia (fruiting structures) with a brown or dark brown disc. The thallus has a sleek, continuous structure that is not areolate, with greyish colours. The apothecia, which initially appear submerged within the thallus, later partially emerge or can be seen in structures called thalline warts....read more on Wikipedia.
