Bryophytes of Pico do Cuscuzeiro and Pico do Cardoso, S o Paulo state, Brazil

This paper presents the bryoflora of mountain peaks in the state of S o Paulo (SP). Sixty-five species of bryophytes werefound to occur on Pico do Cuscuzeiro (1,279 m), in Ubatuba, and 72 species on Pico do Cardoso (840 m), in Cananeia.Samples were collected of soil, rocks, the bark of living and dead phorophytes, and leaves between 1984 and 1995, withall material deposited in the Herbarium Maria Eneyda Pacheco Kauffmann Fidalgo (SP) and the Herbarium Rioclarense(HRCB). Hepatics and epiphytes collected on from single kind of substrate dominate the species list, which totals 107species for both peaks surveyed. With the exception of Mytilopsis albifrons Spruce, the 106 remaining species all representnew records for S o Paulo. Our checklist increases the list of bryophytes known to occur in mountain peaks across Brazilby 46%, making a new total of 180. The studied bryoflora is most similar to the bryoflora of the ‘paulista’ Atlantic rainforest than that one of peaks in other states of Brazil. Adelanthus carabayensis (Mont.) Grolle and Syzygiella integerrimaSteph. are new records for the state of S o Paulo.
