Saprobic or parasitic on leaves. Sexual morph: Ascomata superficial, orbicular, membraneous and carbanaceous, solitary to gregarious, or in groups, shield-like, dark brown to black. Hamathecium comprises numerous, hyaline, filiform, aseptate pseudoparaphyses, with pale yellow apices. Asci 8-spored, bitunicate, clavate to ovate, bitunicate, pedicellate or apedicellate, with thick apex, sometimes ocular chamber present. Ascospores clongobate, eliipsoidal, 1-septum, initially hyaline becoming brown at maturity, slightly constricted at the septum, rough-walled, covering with a thin sheath, guttulate or not. Asexual morph: Undetermined.
Notes: Doidge (1921) introduced Palawaniella with the type species of P. eucleae. However, P. eucleae was synonymized under P. orbiculate by Doidge (1942). Species of Palawaniella are characterized by stromatic ascomata that are gregarious in the centre of black spots, becoming flattened and with a single locule (Inácio and Cannon 2008).
Type species: Palawaniella eucleae Doidge, Bothalia 1(1): 16 (1921).
Other accepted species: species Fungorum – search Palawaniella.
