Third-five transects were analyzed (10 × 10 m) for the floristic survey and eighteen transects (six for each vegetation type: Igapó Forest (IG), Várzea Forest (VA), and Terra Firme Forest (TE)) were randomly analyzed in order to compare the bryophyte communities. We found 118 species: 37 mosses and 82 liverworts Lejeuneaceae (63 species) was the richest among the liverwort families to liverworts and Calymperaceae (eight species) among mosses. The estimated species richness was lower than expected, but the collector’s curve was stabilized. The most colonized substrate was live bark (101 spp., 45 exclusive) followed by decomposing bark (66 spp., 16 exclusive). The results show that the vegetation types analyzed have has differences in bryophyte community richness (IG > TF > VA) and composition, due to the occurrence of exclusive species. The cluster (UPGMA) and ordination (NMDS) analyses indicated the presence of community structure among the three phytophysiognomy.Acesso AbertoBriófitasFitofisionomiaFloresta de terra-firmeFloresta de várzeaFloresta de IgapóEspécie (Botânica)Artigo de Periódicohttp://dx.doi.org/10.1590/2236-8906-54/2015
