Hydropunctaria alaskana

About

Hydropunctaria alaskana is a species of crustose lichen in the family Verrucariaceae. The lichen forms a dark, cracked crust on rocks near the sea that occasionally become submerged by water. The species is distinguished by its small, dome-shaped fruiting bodies that protrude from the dark crust and produce microscopic spores inside flask-shaped structures. It was discovered in 2020 in Alaska's Glacier Bay National Park and Preserve and is also found on islands in Alaska and British Columbia.
