Types of Conidiophore Formation

Simple, unbranched conidiophores:

Branched conidiophores:

  • Example of a branching pattern of conidiophores bearing clusters of conidia at their tips.
  • E.g. Trichoderma viride
Coremium(a):
Diagram illustrating a coremium.
  • Conidiophores are aggregated together to form a vertical stalk-like coremium.
  • At the top of the coremium the conidiophores branch and conidia develop at the tips of the branches.
  • E.g. Penicillium claviforme.
Pycnidium(a):
Diagram illustrating a pycnidium.
  • A flask-shaped structure with conidiophores developing from cells of the pycnidial wall.
  • E.g. Phoma species.
Acervulus(i):
Diagram illustrating an acervulus.
  • A flat, open pad of short conidiophores growing side-by-side.
  • The conidiophores develop from the underlying mass of somatic hyphae.
  • E.g. Colletotrichum species.
Sporodochium(a):

  • A cushion-shaped mass of short conidiophores.
  • E.g. Epicoccum species.
