Notes – Dacampia, typified by Dacampia hookeri, was introduced by Massalongo (1853). Most species of Dacampia are parasitic and form necrotic patches on the host thallus or tend to be commensalistic. However, the type species is lichenized (except for juvenile stages that might facultatively transform the thallus of Solorina bispora), forming white lichenized thalli with Coccomyxa and external cephalodia with Nostoc (Henssen 1995). It grows on soil in arctic-alpine habitats. The closely related D. engeliana is an obligate lichenicolous fungus but modifies its host lichen to form a similar thallus structure as found in D. hookeri (Henssen 1995). Ertz et al. (2015) re-collected the type species and D. engeliana with LSU sequence data available in GenBank. For morphology of type species see Henssen (1995) and Ertz et al. (2015). A key to seven species is given by Halici & Hawksworth (2008).

Scale bars: a, h, i = 1 mm, b = 500 μm, c = 100 μm, d = 50 μm, e = 20 μm, f, g = 10 μm.
