Geotrichum candidum and Trichosporon capitatum can already be distinguished in microscopic preparations of sputum. Their arthrospores and hyphae differ in shape and size, and the predominant form (arthrospores vs. hyphae) in infected samples also varies. Diagnostic features and microphotographs are presented.
