 Giuseppe De Notaris (1847) considered the "Hysteriaceae" to belong to the pyrenomycetes and used spore pigmentation to classify hysteriaceous fungi into the "Phaeosporii" and the "Hyalosporii".Pier Andrea Saccardo (1873) initially followed Fries, but later (1874) placed hysteriaceous fungi in the pyrenomycetes, and carried de Notaris’ (1847) spore classification scheme further by dividing the Hysteriaceae into nine sections based on pigmentation and the morphology of spore septation.Job Bicknell Ellis and Benjamin Matlack Everhart (1892), in their "North American Pyrenomycetes", tentatively included the "Hysteriaceae", but stated that they had not at first intended to do so due to the transitional nature of the hysterothecium.
