Antheridium and Ascogonium
Sexual reproduction in Aspergillus is rare and takes place in favourable conditions. Sex organs are produced on the same mycelium which has produced conidia. Male organs are called Antheridium or Pollinoduim and female are called archicarp or Ascogonium. Female organs develop as a branch of hypha. The antheridium curves round and bend towards the apex of archicarp as a result of which they become spirally coiled and their tips get fused.
