Jamesiella dacryoidea

Jamesiella dacryoidea is a thin, translucent grey-colored, teardrop-shaped lichen species that is differentiated from other species of Jamesiella by its color and shape. This lichen grows on rocks near bodies of saltwater, typically on top of bryophytes. Jamesiella dacryoidea is found on the southeast coast of Alaska and was discovered in Petersburg Borough, Alaska. This species is named after its teardrop shape, as dacryoideus in Latin means tear-shaped.
