Lecanora viridipruinosa

Lecanora viridipruinosa is a species of crustose lichen in the family Lecanoraceae. Found in Alaska, it was formally described as a new species by lichenologists Måns Svensson and Toby Spribille. The type specimen was collected from the Hoonah-Angoon Census Area in Glacier Bay National Park. Here it was found growing on exposed argillite rock in an alpine heath at an elevation of 920 m. The specific epithet viridipruinosa refers to the greenish on the  of the apothecia. The lichen is only known to occur in the type locality.
