Physciella

Physciella is a genus of lichen-forming fungi in the family Physciaceae. Circumscribed by the lichenologist Ted Esslinger in 1986, it is distinguished from the similar genera Physcia and Phaeophyscia by its (comprising long narrow wavy parallel hyphae) lower cortex, the lack of the secondary metabolite (lichen product) atranorin in the upper cortex, and short, ellipsoid-shaped conidia.
