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).

a) the average ascospore volume in tetrasporic asci: 15,000 um3 instead of 10,000 um3 and 5,000 um3, the last two measured in the single last two Tuber species, respectively; b) the ascospores shape and ornamentation: spherical (22.5-55 um), rarely sub-spherical, enclosed by a reticulate-alveolate exosporium with net meshes delimited by 4-6 walls 5-7.5 um high; c) a peridium constituted by very small and flat warts, almost never transversely striated; d) the odour, at first phenolic (3-methylanisole), then grateful due to the presence of ethyl-methyl-chetone, without any phenolic component; e) thecolour of the gleba, light-brown with numerous, irregularly flexuous and subtle sterile veins; f) theovoid (77-95 x 7-115 um) asci, supported by a hooked pedicle and containing 1-6 spores.
