Endophytic, saprobic or pathogenic on leaves of grasses and trees. Sexual morph: Undetermined. Asexual morph: Coelomycetous. Conidiomata pycnothyrial, superficial on leaves, round, brown, with central column of cells; ostiole lacking, margin of catenate, darker brown cells. Conidiophores reduced to conidiogenous cells arising from a central columella, doliiform to ellipsoid, hyaline, smooth, with a single conidiogenous locus, phialidic. Conidia solitary, hyaline, aseptate, smooth, guttulate, falcate to naviculate or ellipsoid, apex subobtusely rounded, base truncate; with or without unbranched polar appendages, not delimited by septa (adapted from Crous et al. 2018d).
Notes: Tracyllaceae was introduced by Crous et al. (2018d) to accommodate the monotypic genus Tracylla. This was well-supported by the multigene analysis (ITS, LSU, SSU) of T. aristata and T. eucalypti that form a monophyletic lineage which is distinct from other groups in Sordariomycetes.
Type genus: Tracylla (Sacc.) Tassi
