A total of 21 taxa were studied, 8 belonging to Cyanobacteria and 13 to Chlorophyta. The most common species within the samples studied are the chlorophytes Klebsormidium flaccidum and Muriella terrestris, and the cyanobacteria Microcoleus vaginatus and Phormidium autumnale. Species distribution is discussed in relation to microclimatic conditions. It is found that in some cases, samples taken near ground level are characterized by the absence of cyanobacteria, which are however present in samples taken from places exposed to sunlight, at 50 m height. The possible biodeterioration mechanisms in which these chlorophytes and cyanobacteria could be involved are discussed.
