Fuscopannaria rugosa

Fuscopannaria rugosa is a species of corticolous (bark-dwelling), lichen in the family Pannariaceae. It is found in Hubei and Guanxi in China, where it grows in mountainous forests. Fuscopannaria rugosa is identifiable by its foliose-squamulose thallus, which has longitudinal wrinkles on the upper surface. It also has a distinct hypothallus, a relatively thick algal layer, and a cortex made up of thick-walled cells in both the thalline and apothecial structures. It produces simple, hyaline ascospores that have a smooth, pointed tip (epispore) at their apex....read more on Wikipedia.
