The organism has been found to be the cause of opportunistic infections in immune compromised individuals.
Growth is rapid on PDA and MEA. Growth is restricted on DG-18 agar due to the inhibiting effects of the dichloran. The organism can be identified on an Air-O-Cell cassette sample if several are present in the sample. The spore looks a bit like a very tiny walnut shell with ridges and an irregular assymetric shape.
