Orbilia is a genus of fungi in the family Orbiliaceae. Anamorphs of this genus include the Arthrobotrys, Dactylella, Dicranidion, Dwayaangam, Helicoön, Monacrosporium, and Trinacrium. The genus was established in 1836 by Elias Magnus Fries to accommodate the species Peziza leucostigma. The mycologist Josef Velenovský wrote articles describing species found in Bohemia and Moravia (Czechoslovakia). In 1951, Fred Jay Seaver recorded 20 species in North America, and R.W.G. Dennis later described 9 species from Venezuela. According to the Dictionary of the Fungi (10th edition, 2008), there are about 58 species in the genus.
