Settle plates, exposed in a newly‐built, air‐conditioned hospital, were compared with similar samples from a modern, naturally ventilated hospital. Fewer fungal colonies were found in the air‐conditioned hospital. Most airborne fungi found in the naturally ventilated hospital wards are probably introduced with the ventilating air. There was much less difference between the two hospitals in the numbers of Cl. welchii recovered and it seems likely that these organisms are dispersed from human sources within the hospital in numbers comparable to those brought in with the ventilating air in naturally ventilated hospitals. A description of a portable anaerobic incubator suitable for field studies is also given.
