Air-borne fungi in Barcelona City (Spain). I. A two-year study (1976-1978).

Quantitative and qualitative studies were made of the fungi of the air in Barcelona City. The genera Cladosporium and Alternaria formed two of the most important components of the fungus population studied during a two-year period running from January 1976 through January 1978. Penicillium species formed the 16.3% of the total colonies while Aspergillus species represented only the 2.8%. The occurrence of the genera was greatly affected by climatic conditions. An attempt was made to summariza the data of various kinds of fungi on a volumetric basis. Most of the fungi reported here have been identified as far as genera.
