title: Ultrastructure of spore formation in Paracoccidioides brasiliensis.
abstract: Chlamydospores and arthrospores are produced by the mycelial phase of Paracoccidioides brasiliensis in submerged cultures at 23 degrees C. Arthrospores are formed by extrusion in specialized, sporogenous hyphae. The absence of any unique morphological characteristic in chlamydospores and arthrospores discards the use of spore morphology as a taxonomic criterion.
