“…Ganoderma spores are considered to be a moist-air spore type because their concentrations showed marked seasonal and diurnal differences with the highest numbers during the wet season, and water is an important factor involved in its spore release. This agrees with the reports of McCracken (1987) and Hasnain et al (2004), who stated that humidity levels of about 70 % were associated with increased concentrations of Ganoderma spores. The diurnal pattern with a peak early in the morning and the secondary peak late in the evening was noted in England (London and Worcester) (Lacey 1962; Sadyś et al 2014), Canada (Tarlo et al 1979) and New Zealand (Hasnain et al 1984).…”

The aim of the study was to determine functional relationships between composition of air spora and meteorological factors, using multivariate statistical technique: canonical correspondence analysis (CCA). Analyses were conducted for the data collected during the 4 year (2007)(2008)(2009)(2010) and, in order to show the dynamics of such relationships, for each year separately. The CCA results indicated that all statistically significant variables accounted for 15.3 % of the total variance in the spore data in the 4 years. The largest amount of the total variance was explained in this period by the mean air temperature (9.2 %). The meteorological factors impacted spore composition differently in different years, when analysis was done for each year separately. The highest values of the total variance in the spore data, explained by the statistically significant variables, were found in 2010 (32.3 %), with the highest contribution of mean air temperature (23.8 %). In that year, the above-mentioned parameter had the lowest value in comparison to other years. Canonical correspondence analysis provides not only a comprehensive assessment of the impact of meteorological factors on specific spore combinations in the air, but also informative graphical presentations of the results, illustrating the correlation between the occurrence of particular spore taxa and meteorological variables.

“…It is well known that high humidity and rain favour the production and liberation of basidiospores. This compares with the reports of McCracken (1987) and Hasnain et al (2004) that humidity levels of about 70% are associated with increased concentrations of Ganoderma sp. spores.…”

“…Studies from various parts of the world have clearly implicated Ganoderma sp. spores as aeroallergens (Tarlo et al 1979; Hasnain et al 2004). In various reports, 10–48% human sensitisation in skin prick tests has been attributed to Ganoderma sp.…”

Ganoderma sp. is an airborne fungal spore type known to trigger respiratory allergy symptoms in sensitive patients. Aiming to reduce the risk for allergic individuals, we analysed fungal spore circulation in Szczecin, Poland, and its dependence on meteorological conditions. Statistical models for the airborne spore concentrations of Ganoderma sp.—one of the most abundant fungal taxa in the area—were developed. Aerobiological sampling was conducted over 2004–2008 using a volumetric Lanzoni trap. Simultaneously, the following meteorological parameters were recorded: daily level of precipitation, maximum and average wind speed, relative humidity and maximum, minimum, average and dew point temperatures. These data were used as the explaining variables. Due to the non-linearity and non-normality of the data set, the applied modelling techniques were artificial neural networks (ANN) and mutlivariate regression trees (MRT). The obtained classification and MRT models predicted threshold conditions above which Ganoderma sp. appeared in the air. It turned out that dew point temperature was the main factor influencing the presence or absence of Ganoderma sp. spores. Further analysis of spore seasons revealed that the airborne fungal spore concentration depended only slightly on meteorological factors.

“…The basidiospores of Ganoderma, commonly known as a bracket fungus or wood decay fungus, are an important and prevalent group of airborne fungal spores worldwide. Studies from various parts of the world have clearly implicated Ganoderma spores as aeroallergens [27], and they have been implicated in the elicitation of respiratory allergic diseases. The high concentration Ganoderma spores in the air of Szczecin is the result of the proximity of two major forest complexes: Beech Forest and Wkrzańska Forest.…”

A calendar of fungal spore seasons for Szczecin during 2013 was established using a 7-day volumetric Lanzoni trap. Thirty-five spore taxa were identified. The dominant spore types detected were Cladosporium (66%), Didymella (29%), Alternaria (1.67%), and Leptosphaeria type (1.21%). The spores were present throughout the study year. However, there was a wide daily fluctuation in the concentration values with a tendency towards an increase during the summer months. Seasonally, the spore levels of Cladosporium, Alternaria, and Leptosphaeria type peaked in summer (June–September), while those of Didymella mainly in July. Most of the other spore types had the highest concentrations in summer but occurred in the air from spring to late fall.
