The results of a study on the bryophyte flora of the Sasso Pisano geothermal area (Pisa) are reported in this paper. A total of 16 mosses and 3 liverworts were found. Two moss species, Campylopus pyriformis (Schultz) Brid. and Leucobryum juniperideum (Brid.) Müll. Hal. and one liverwort species, Odontoschisma denudatum (Mart.) Dumort., are new for Tuscany. The recorded bryoflora is not rich in species but includes some rare and ecologically interesting taxa.
