First fungal spore calendar of the middle-west of the Iberian Peninsula

The aim of this paper was to make a first approximation of the fungal spore airborne content in Valladolid along the year, constructing the first spore calendar for the middle-west of Spain. So that, we monitored the city during 2005 and 2006, being Cladosporium the most abundant type, present all over the year (together with Pleospora ). The greatest atmospheric spore diversity was observed in April in contrast with February. The intra-diurnal pattern for Alternaria , Cladosporium and Dreschlera was very similar with an hourly concentration percentage decreasing along two periods, whereas Coprinus , Ganoderma and Periconia showed a clearly nocturnal pattern. The meteorological parameter that most influenced airborne spore concentrations was temperature, significantly and positively in the case of dry-air spores but negatively for wet-air spores.
