The Coniochaetales are an order of fungi within the class Sordariomycetes.

[2] However, this taxonomic placement has been challenged by other authorities, and the Coniochaetales was proposed to include the family Coniochaetaceae.

[3] In 2020, family Cordanaceae (with its monotypic genus Cordana Preuss and various species) was added to the order.

[4] Species in this family are characterized by having germ-slits in the ascospores, a morphological feature that distinguishes them from species in the Sordariaceae.

[5] Phylogenetic research in 2006 revealed that four genera in the family Coniochaetaceae, Coniochaeta, Coniochaetidium, Ephemeroascus, and Poroconiochaeta, were not monophyletic, and were all made synonymous with Coniochaeta.
