The development and structure of thick-walled, multicellular, aerial spores in Diheterospora chlamydosporia (=Verticillium chlamydosporium).
The aerial, thick-walled spores in Diheterospara chlamydosporia arose as terminal swellings on erect hyphae.  Repeated septation of the continuously swelling spore resulted in a multicellular structure.  Immediately after the onset of septation secondary wall material was laid down between the two-layered primary wall and the plasmalemma.  The presence of secondary wall material indicates that the multicellular spore is a dictyochlamydospore and not an aleuriospore.  The relationship between chlamydospores and aleuriospores in other fungi is discussed.
