Hypogymnia congesta is a rare species of foliose lichen in the family Parmeliaceae that is found in China. It was formally described as a new species by Bruce McCune and Chicita Culberson in 2003. The type specimen was collected near Wei Den village, behind Lou Ma Deng Mountain in Weixi County (Yunnan), at an elevation of 3,000 metres (9,800 ft). There it grows on the bark and wood of conifers and bamboo. Hypogymnia congesta has a brown to brownish-grey foliose thallus measuring up to 8 cm (3.1 in) long or broad, with a cartilage-like texture. Its ascospores measure 7–8 by 5.0–5.5 μm. The lichen is chemically distinct, containing virensic acid and physodic acid, but lacking physodalic acid. Virensic acid is otherwise unknown from the genus Hypogymnia.[1]
