According to recent studies, Ganoderma may be the third genus, after Alternaria and Cladosporium, the spores of which cause symptoms of allergy, and concentration is related to meteorological factors. The aerobiology of Ganoderma spores in Szczecin in urban and suburban districts was examined using Lanzoni Volumetric Spore Traps in 2008–2010. Ganoderma spores were present in the atmosphere on more than 90% of the days from June through September with peak concentrations in June, July and September. The number of days with spores was lower in the suburban district, while the total number of spores collected was higher there than in the urban district. Correlation and multiple regression analyses revealed weak relationships between Ganoderma and meteorological conditions, while testing the significance of differences between the districts showed that urban development did not have a clear impact on the values of meteorological parameters. A significantly higher abundance of spores in the suburbs of Szczecin seemed to be conditioned by the closeness of potential area sources. This study indicates that a single measuring site in the city centre insufficiently reflected the dynamics and level of [i]Ganoderma[/i] spore concentration in peripheral districts.
