Fatal pulmonary infection caused by the basidiomycete Hormographiella aspergillata.

A fatal case of a pulmonary infection caused by Hormographiella aspergillata, the anamorph of the mushroom Coprinus cinereus, is reported for a patient receiving treatment for a second relapse of acute lymphoblastic leukemia. The filamentous basidiomycete was identified with restriction fragment length polymorphism patterns of PCR-amplified internally transcribed spacers and small subunit ribosomal DNA with four restriction enzymes. The patient failed to respond to treatment with amphotericin B and itraconazole. The fungus was cultured from the lungs at autopsy: the MIC of amphotericin B for the fungus was low (0.5 mg/liter), and that of itraconazole was high (8 mg/liter).
