The Microascaceae are a family of fungi in the class Sordariomycetes, subclass Hypocreomycetidae.

[1] The family was published by David Malloch in 1970, an emended description based on Everet Stanley Luttrell's original 1951 publication.

[3] Microascaceae species have spherical to irregularly shaped, darkly colored fruit bodies.

The smooth spores are reddish brown to copper colored, one-celled, and have a germ pore at one or both ends.
