 Barr (1979) also originally held a wide view of the Hysteriales, but, unlike Luttrell (1973), maintained the two family distinction.Later, Barr (1983) abandoned the Hysteriales and placed the Hysteriaceae within the Pleosporales due to the presence of cellular pseudoparaphyses, asci borne in a basal rather than peripheral layer and ascospores typically showing bipolar asymmetry.Barr noted (1987) that the relationship of some members of the Hysteriaceae was with the Cucurbitariaceae or with the Pleosporaceae.
