The characteristics of the mite infested cultures, which permit the suspicion of infestation and even to have the certainly of this by the simple observation of the culture tube are described in detail. The authors study the morphology, evolution and habits of the mites which infested the fungi collection of the Instituto Oswaldo Cruz.
