 Although Duby’s (1862) method of classification, based on dehiscent versus nondehiscent asci, was not followed by subsequent workers, he was the first to propose dividing hysteriaceous fungi into what was later to become two distinct families.However, one hundred years would pass before this distinction was fully recognized.Although Franz von Höhnel (1918) considered the Hysteriaceae to be pyrenomycetes, he proposed a radical revision of the Hysteriales.
