|A 60 year old previously well male boilermaker presented with haemoptysis. He was a light smoker and had no travel history to the USA or South America. Chest X-ray showed hyper-inflated lungs and a CT showed upper lobe emphysema, no mass lesions were visible. Bronchial washings grew the fungus shown below.|
Cultures on Sabouraud's dextrose agar showed a suede-like to downy, greyish white colony with a tan to brown reverse.
Microscopic morphology showing typical single-celled, hyaline, rectangular to barrel-shaped, alternate arthroconidia, separated from each other by a disjunction cell. As both the culture and microscopic features closely resembled Coccidioides immitis an exoantigen test was done. Exoantigen Test: showing a positive result for Coccidioides immitis.
