Abstract

A study of the algal flora was conducted in the Renaissance and Baroque cloisters of the Santo Domingo College (Orihuela, Alicante, SE Spain). 14 epilithic algal species belonging to the Cyanophyceae have been found in which the Chroococcales predominated the Oscillatoriales. The genera that showed the largest diversity were Chroococcus and Tolypothrix, whereas the most frequent genus was Pseudocapsa. The effects that the algae growing in the Santo Domingo College had may be summarized in the formation of dark-coloured stains with their consequent unsightly effect, and also in the creation of a substratum that favours the growth of other organisms, which in turn helps mechanical processes, accelerating the chemical degradation processes.
