Diversity, taxonomy and distribution for Brazilian states of the families Bartramiaceae, Brachytheciaceae, Bryaceae, Calymperaceae, Fissidentaceae, Hypnaceae and Leucobryaceae (Bryophyta) of the Scientific Station Ferreira Penna, Caxiuanã, Pará, Brazil)

Abstract

The inventory of the species of mosses (Bryophyta) was conducted in the Scientific Station Ferreira Penna, municipality of Melgaço, state of Pará. This station possesses 85% of its area of well conserved, terra-firme vegetation. Although the phanerogams are relatively well studied, the mosses are only now moving forward with this work. Besides inventorying the species of mosses inhabiting the area, other objectives are to expand knowledge regarding the geographical distribution of the species reported for the area, and to register the substratum type and ecosystem where they occur. There were identified 84 species, 37 genera and 19 families. This work is part of a series of studies accomplished with the mosses of ECFPn, just treating the 47 species belonging to the families Bartramiaceae, Brachytheciaceae, Bryaceae, Calymperaceae, Fissidentaceae, Hypnaceae and Leucobryaceae. For each táxon they were mentioned place-type, herbarium, references of descriptions, comments regarding morphological characteristics, Brazilian geographical distribution and examined material. Herein we include new references for Amazonian Brazilian, Fissidens pauperculus M.Howe and Octoblepharum costatum H.A.Crum and for the state of Pará, Syrrhopodon incompletus Schwägr. var. berteroanus (Brid.) W.D.Reese and Leucobryum crispum Müll.Hal.
