The family is characterized by flattened and scutate ascomata (thyriothecia), wich are usually ostiolate and develop superficially or in the cuticle of the living host's leaves; the peridium is dark coloured, mostly bluish-green, bluish-black or brown, and has a non-radiate, often meandrous interwoven cells structure (textura epidermoidea); the asci are bitunicate, clavate to cylindrical, ovate or saccate, and the ascospores are hyaline, long clavate with mostly more than two transverse septa; the pseudoparaphyses are narrowly cellular and tend to deliquesce in mature specimens and are not always present (Batista, 1959; von Arx & Muller, 1975; Wu et al., 2011; Hyde et al., 2013; Hongsanan et al., 2014).
Pertithecia are opaque, ostiolate, with blunt, narrow or beaked apex and its wall membranous, fragile, brittle with age, distinctly cellular, ornamented with appendages in the form of diversely modified and variously coloured hairs called terminal hairs.
It has been accepted by a number of workers [11, 12, 13] that closely related ostiolate and cleistothecial genera are better accommodated in one rather than in separate families as originally suggested by Cain [3].
