Lobothallia is a genus of lichens in the family Megasporaceae. Species in the genus have foliose thalli that become crustose areolate in the center with age, and grow on calcareous to siliceous rocks.[2]: 306–7 The crustose part of the body may keep its lower cortex,[2]: 306 though not always.[3] Dark brown to black apothecia may be sunken into the surface of the thallus, as indicated in the common name puffed sunken disk lichen.[2]: 306 Members grow to 3–5 cm (1.2–2.0 in) or more radiating lobes (placodioid).[3] The photobiont is green alga from the genus Trebouxia.[3] The genus is represented in Eurasia, Asia, North Africa, Central America, western North America, and Australia.[3]
As of December 2021, Species Fungorum accepts 17 species of Lobothallia.[4]
