Nigrohydnum nigrum Ryvarden is a rare polypore previously known only from two records in Brazil. During a herbarium revision at SP we have identified an old voucher specimen, extending the previously known geographic distribution to the Atlantic rain forest of Porto Alegre, Rio Grande do Sul State, Southern Brazil.

Palynological studies in the marsh forest of Serra Velha (29º36’S – 51º38’W), Rio Grande do Sul, Brazil, detected a plant succession through hydrosere from a water body already somewhat filled up by herbaceous vegetation at 9800 ± 90 yr BP. The climatic amelioration at the beginning of the Holocene accentuated the filling up process. Later, between 7800 – 7280 ± 60 yr BP, a short phase of significant influence of the forest over the marsh occurred. A new significant expansion of the forest, beginning at about 6000 yr BP took place. This gave rise to the present forest which is represented by many species of the Atlantic rain forest. Compared to the already existing palynological data about the Coastal Plain, it becomes evident that the present Serra Velha forest is older, which seems to indicate the importance of the foothill forests of Serra Geral in forming the present coastal vegetation in Rio Grande do Sul.

A new species of leaf-feeding thrips is described, from the Atlantic Rain Forest in Rio Grande do Sul State, Southern Brazil. Holopothrips claritibialis sp. nov. differs from other species of the genus in the combination of the following characteristics: all tibiae predominantly yellow; maxillary stylets retracted near the postocular setae; metanotum with reticulation, elongated on anterior half and equiangular on posterior half; pelta with equiangular reticulation medially but weak or absent laterally and posteriorly; glandular areas present on sternites VII–VIII in males (usually three glandular areas on each sternite). This species causes deformations and rolls on leaves of Mollinedia schottiana. Some aspects of the biology and intraspecific variation of this species are discussed.

Faunistic inventories regarding natural history of amphibians and reptiles are considered scarce and very little is known about their assemblages in urban areas; the Pampas morphoclimatic domain, also known as Uruguayan Savannah or Southern Grasslands, is also poorly known regarding their faunal composition.  Herein, we present a checklist of 16 amphibian and 20 reptile species recorded over a course of four years in the Instituto Federal de Educação, Ciências e Tecnologia, Câmpus Pelotas-Visconde da Graça, in Pelotas, Rio Grande do Sul, Brazil. We also present data on natural history and discuss conservation efforts to be undertaken in the area, in one of the least preserved and known Brazilian morphoclimatic domains, providing insights into urban herpetofaunal diversity patterns and showing the importance of modified areas in its conservation.

According to Baldissera et al. (2004) the Rhinella crucifer group includes five recognized species: Rhinella crucifer (Wied-Neuwied, 1821); R. ornata (Spix, 1824); R. henseli (A. Lutz, 1924); R. abei and R. pombali (Baldissera, Caramaschi & Haddad, 2004). The distribution of this group is associated to the Atlantic Rain Forest, from Ceará to Rio Grande do Sul, adjacent areas in Minas Gerais and São Paulo, Brazil. One species also occurs in Uruguay and northeastern Argentina, in the Misiones and Corrientes provinces (Baldissera et al. 2004; Frost 2011). Thomé et al. (2010) in a phylogeographic study of the Rhinella crucifer group identified two subclades in northeastern Brazil and adjacent areas: one ranging from Bahia to Paraíba and another from Minas Gerais to Espírito Santo. Of five species belonging to the R. crucifer group, only two have described tadpoles, R. ornata and R. pombali (Heyer et al. 1990, where the tadpole described as R. crucifer represents R. ornata; Lourenço et al. 2010). Here we described the tadpole of R. crucifer from a population from southern Bahia.

ABSTRACT Hygrocybe conica var. conica and H. nigrescens var. brevispora were collected in the Atlantic Rain Forest of the States of Paraná and Rio Grande do Norte States, respectively. These two taxa were reported in mushroom checklists of Brazil; however, their morphological features and variations have been hitherto poorly documented. Thus, it is provided for the first time a complete description for these two Brazilian varieties. Hygrocybe conica var. conica was reported in the last century for the southeast region, more precisely from the mixed ombrophilous forests of São Paulo State. Presently, this variety is a new record for the seasonal semideciduous forests of Paraná State, southern Brazil. Hygrocybe nigrescens var. brevispora was known from coastal ecosystems of the south and southeast regions; it is also being indicated here as a new record for the northeast region.
