oidia

"carpospores" or possibly chlamydospores similar to the endospores of yeast. [v. 03 p. 0157] The former also looks on the ordinary disjointing bacterial cell as an oidium, and it must be admitted that since Brefeld's discovery of the frequency of minute oidia and chlamydospores among the fungi, the probability that some so-called bacteria -- and this applies especially to the branching forms accepted by some bacteriologists -- are merely reduced fungi is increased.
