 In Rabenhorst’s "Kryptogamen-Flora, Die Pilze", Heinrich Rehm (1896) compromised and placed the "Hysteriales" as an order intermediate between the pyrenomycetes and the discomycetes.Duby (1862) considered hysteriaceous fungi to belong to the pyrenomycetes and proposed two sections, the "Hystériées" to include "Hysterium", "Glonium", and "Actidium" Fr.among others, and the "Lophiées" to accommodate "Ostreichnion" Duby, "Mytilinidion" Duby and "Lophium" Fr.
