Mediterranean ecosystems have not been investigated as natural habitats for microorganisms in general, and microfungi in particular. Plants harvested in "Serra da Arrábida" (38 degrees 27' N, 9 degrees 02' W), a Mediterranean ecosystem in Portugal, were analyzed for the filamentous microfungi inhabiting their surface. Two field locations with distinct climatic characteristics were studied: 'Fonte do Veado' (38 degrees 28'50" N, 9 degrees 0'17" W; 300 m elevation) located on the northern slope, and 'Mata do Solitário' (38 degrees 27'55" N, 8 degrees 59'35" W; 50 m elevation), on the southern slope. From Veado zone, leaf samples yielded a total of 3,049 isolates, ranging from 317 to 1,328/sample (mean = 762). The number of species/sample ranged from 12 to 24. From Solitario zone, leaf samples yielded a total of 1,337 isolates, ranging from 189 to 528/sample (mean = 334). The number of species/sample, in this case, ranged from 10 to 17. Veado zone showed a wider range of species. The fungal species more frequently isolated from both zones (Aureobasidium pullulans (De Bary) Arnaud, Cladosporium cladosporioides (Fresen.) De Vries, C. sphaerospermum Penzig and Alternaria alternata (Fr.) Keissler) were found in all plant samples and represents 80% (Veado) and 85% (Solitario) of the total isolates.
