Pannaria complanata

Pannaria complanata is a species of corticolous (bark-dwelling), squamulose (scaley) to foliose (leafy) lichen in the family Pannariaceae.^[1] It was formally described as a new species in 2001 by the Norwegian lichenologist Per Magnus Jørgensen. The type specimen was collected from the Doddabetta peak in the Nilgiri Mountains at an altitude of about 3,000 m (9,800 ft). The lichen makes circular patches typically up to about 5 cm (2 in) in diameter, comprising brownish, flat lobes measuring up to 2 mm wide. The photobiont partner is a member of the cyanobacterial genus Nostoc. The PD+ (orange) chemical spot test reaction indicates the presence of pannarin, a lichen product. The geographic range of the lichen includes India, Sri Lanka, and Indonesia.^[2] In India it is found only in the Western Ghats, having been recorded from Kerala and Tamil Nadu.^[3] In this country Pannaria complanata often associates with moss genus Hyophila.^[4]
