Plural of hemiascus; half-shaped or partially-formed sac-like structures in certain fungi that contain spores.
From Latin hemi- (half) + ascus (sac or vessel). In mycology, this term describes a specific fungal reproductive structure.
Fungi are incredibly diverse—while most use standard ascus structures, some fungi evolved hemiasci as a half-formed version, showing that evolution sometimes creates intermediate forms or variations on successful designs.
