Fimicolous organisms are those that can grow on dung. These substrates offer conditions that favour colonization by microorganisms, such as high nutrient and moisture content and an alkaline-neutral pH that is especially advantageous in arid/desertic regions. There are about 250 species of myxomycetes known from Brazil, which are distributed in all geographic regions and biomes, obtained mainly from plant-derived substrates. However, there are some reports of fimicolous myxomycetes in Brazil. In this study, we expand this knowledge with new records of fimicolous myxomycetes in multiple Brazilian biomes. Between 2017 and 2018, horse and cattle dung samples were collected in municipal areas in the State of Goiás (Cerrado biome): Pirenópolis, Goiás, and Porangatu; and the State of Mato Grosso (Pantanal biome): Poconé. Samples were incubated in moist chambers and monitored for four months. Myxomycetous fructifications were observed, photographed under stereo and light microscopes, and morphologically identified. Vouchers were deposited at the HUEG Herbarium. A total of five species of myxomycetes were recorded: <em>Arcyria cinerea and <em>Physarum viride (Pirenópolis), <em>P. cinereum (Goiás City), <em>P. melleum</em> (Porangatu), and <em>Perichaena corticalis</em> (Poconé). They represent the first records of fimicolous myxomycetes from the Brazilian Cerrado and Pantanal biomes. Additionally, <em>P. melleum</em> was reported as fimicolous for the first time in Brazil and the second time in the world; <em>P. corticalis</em> was reported for the first time in midwest region as well as for the first time as fimicolous in Brazil; and <em>P. viride</em> was reported for the first time as fimicolous in the world.

New locality records and distribution map for the recently described Elachistocleis magnus are here presented. Originally described from Rondônia state, western Brazil (Amazonia), E. magnus was until now recorded for only two additional localities in the same state. The new records presented herein, which considerably enlarge the known range of the species, include three additional Brazilian states – Amazonas, Pará, and Mato Grosso (including records in the Brazilian Cerrado). We provide color description of the species in life, and discuss variation in habitats used by this species.

The new species Belostoma inusitatum is described and illustrated based on specimens from the west side of the Araguaia-Tocantins basin, in Mato Grosso state in central-western Brazil. This new species is assigned to the B. triangulum species group and compared with its congeners. A key and distribution map for the species of this group are included. The three-articulated antenna without lateral projections of B. inusitatum n. sp. is documented for the first time in Belostoma. Also, the uncommon shape of the prosternal keel, the distinct reduction of the hemelytral membrane, and the diverticulum of the phallosoma sharply incised at the posterior margin are reported for this new species. A discussion about the reduction in the number of antennal articles and the size of the hemelytral membrane in Belostoma and Abedus is presented.

Abstract The Brazilian state of Maranhão is located in a transition zone between the Amazon and Cerrado domains; its geographic position enables the coexistence of species from both biomes. Taxonomic information of Orchidaceae and especially Epidendrum in the state are scarce; thus this study aimed to provide a taxonomic treatment for the genus based on field expeditions and analyses of herbarium specimens (IAN, MAR, MG, NY, SLUI, and UB). Epidendrum is represented in Maranhão by 10 species, of which three are new records: E. amapense, E. anceps, and E. carpophorum. Another three previously cited species, E. nocturnum, E. sculptum, and E. viviparum, were not collected and also not found in the herbaria visited; moreover, these records represent misidentifications. The majority of the species is distributed in the Amazon domain; however, E. macrocarpum is recorded for the first time for the Brazilian Cerrado. Here we provide an identification key, descriptions, photographs, and a distribution map of the species in the state.

Background: The genus Psychotria and Palicourea are reported as a source of alkaloids and iridoids, which exhibit biological activities. This study aimed to evaluate antiproliferative and anticholinesterase activities and quantification of the alkaloids of seven species among the genus found in Mato Grosso do Sul region in Brazil. Methods: Concentrations of alkaloids were measured spectrophotometrically. The extracts were submitted to antiproliferative activity against ten cell lines. The anticholinesterase activity of the extracts was developed using brain structures of male Wistar rats: cerebral cortex, hippocampus, hypothalamus and striatum by the Ellman method. Results: Alkaloids from Psychotria and Palicourea species were quantified which showed values of 47.6 to 21.9 µg/g. Regarding the antiproliferative potential, Palicourea crocea demonstrated selectivity against the 786-0 cell line (GI50: 22.87 µg/mL). Psychotria leiocarpa inhibited cell growth against OVCAR-3 (GI50: 3.28 µg/mL), K-562 (GI50: 5.26 µg/mL), HaCaT (GI50: 27.20 µg/mL), PC-3 (GI50: 34.92 µg/mL), MCF-7 (GI50: 35.80 µg/mL) and P. capillacea showed activity against OVCAR-3 (GI50: 2.33 µg/ml) and U251 (GI50: 16.66 µg/ml). The effect of acetylcholinesterase inhibition was more effective in the hippocampus, demonstrating inhibition for Paliourea crocea, Psychotria deflexa, P. brachybotrya and P. leiocarpa of 70%, 57%, 50% and 40%, respectively, followed by P. poeppigiana and P. capillacea, inhibiting 21%, compared to the control. Conclusion: Herein, the present work showed for the first time, anticholinesterasic and antiproliferative activities of extracts of Palicourea and Psychotria seem to be mainly associated with the levels of alkaloids in the leaves of these species.
