Hysteriales

The Hysteriaceae are a taxonomic family of fungi and the only extant family of the order Hysteriales. Members of the Hysteriaceae are defined by the possession of a sexual structure called the hysterothecium, an elongated structure that opens by a longitudinal slit and releases sexually produced spores. The family is widely distributed, with many species found in temperate regions, and most are saprobic on wood and bark, although a few are parasitic on plants.

The Hysteriales are an order of fungi in the class Dothideomycetes, subclass Pleosporomycetidae. It consists of a single family, Hysteriaceae. Members of Hysteriales produce elongated, often boat shaped sexual structures with slit-like openings (hysterothecia). However species with these structures are very diverse. Comparisons based on DNA sequences indicate species with hysterothecia do not share a single ancestor and therefore species with hysterothecia can be found in several fungal orders. The newest definition of the order relies on DNA sequence differences and a combination of morpholog
