The clinical and pathological findings based on the lesions found at necropsy are described herein. The majority of animals (11/15) had sudden death without clinical signs. In 33.3% (5/15) of the cases, aspergillosis was restricted to the respiratory system and 66.6% showed disseminated disease, with liver, kidney, adrenal gland and gastrointestinal tract involvement. Typical lesions were characterized as white-yellowish granulomatous nodules. To the best of our knowledge, this is the largest series of aspergillosis cases described in penguins in South America.Uma série de 15 casos fatais de aspergilose em pinguins (Spheniscus magellanicus) foi observada durante um período de quatro anos em um centro de reabilitação no Sul do Brasil. Os achados clínicos e patológicos das lesões encontradas na necropsia são aqui descritos. A maioria dos animais (11/15) teve morte súbita sem evidenciar sinal clínico prévio. Em 33,3% (5/15) dos casos, aspergilose estava restrita ao trato respiratório e 66,6% demonstrou doença disseminada, com envolvimento hepático, renal, de glândulas adrenais e trato gastrointestinal. Lesões típicas se caracterizaram por nódulos granulomatosos branco-amarelados. De acordo com a literatura consultada, essa é a maior série de casos de aspergilose descrita em pinguins na América do Sul
