Eduard Eidam first described Hülle cells in 1883 where he termed Hülle cells as a “Blasenhülle” or bubble envelope (Eidam 1883). In different species, Hülle cell like structures are known such as in Candida albicans which produce at the very end of the hyphae globose blisters named chlamydospores (Navarathna et al., 2016). Eidam suggested that Hülle cells originate from the tip of “secondary hyphae” which in turn emerge from “primary hyphae” and develop as a consequence of a swelling process. Hülle cells and the subtending hyphae are connected via two distinct types of septa. The inner one is a single perforate septum where woronin bodies can be observed and represents a typical ascomycetous septum. The second septum which separates Hülle cells from the subtending hyphae is unique and name
