Bryophytes is the term used to define cryptogams avascular plants, commonly known as mosses, liverworts and hornworts, found in damp places. These plants are divided into three divisions, called Anthocerotophyta, Marchantiophyta and Bryophyta. The objective was to survey the flora of mosses in Parque Municipal Ecológico Jirau Alto, Dois Vizinhos, Paraná. The taxa were collected along two transects of 20 meters in length delimited along the study area, one being demarcated in the initial region of the park and the other in the middle portion. The transects were positioned perpendicular to the main trail of the park and over the river Jirau Alto bed. In each transect, they were delimited 4 sampling units (quadrants of two square meters) and equally spaced from each other, two to the right and two to the left side where the corticicolous and terrestrial bryophytes were collected. University herbarium (DVPR) bryophyte samples were also analyzed. Samples of taxa were packed in paper bags, properly labeled and containing information of the collection. The identification was carried out to the lowest possible taxonomic level, based on observation of external and internal morphological characters, performed with optical microscopy, based on the analysis of 86 samples. 24 species of Marchantiophyta were listed and distributed in eight families. Each species was described as their morphological characteristics. Were also described information of the main work in which the species was described, the author of species and the substrate it is. The Marchantiophyta family with greater richness of species was Lejeuneaceae. |
