Vahliella globigera

Vahliella globigera is a species of ground- and moss-dwelling squamulose lichen in the family Vahliellaceae. Found in Alaska, it was described as a new species in 2004 by the lichenologists Alan Fryday and Per Magnus Jørgensen, who classified it in the genus Fuscopannaria; they initially spelled the species epithet as globuligera. The type specimen was collected by Fryday in North Slope Borough, Alaska, on a bank beside a track to the International Tundra Experiment site. Jørgensen transferred it to the new genus Vahliella in 2008. It is the only species in the genus known to contain green algae; the remainder of Vahliella species utilize Nostoc (a cyanobacterium) as a photobiont partner....read more on Wikipedia.
