Notes on 113 fungal taxa are compiled in this paper, including 11 new genera, 89 new species, one new subspecies, three new combinations and seven reference specimens. A wide geographic and taxonomic range of fungal taxa are detailed. In the Ascomycota the new genera Angustospora (Testudinaceae), Camporesia (Xylariaceae), Clematidis, Crassiparies(More)
Leaf litter is a very important primary source of energy in woodland streams. Decomposition of leaf litter is a process mediated by many groups of microorganisms which release extracellular enzymes for the degradation of complex macromolecules. In this process, true fungi and straminipiles are considered to be among the most active groups, more active than(More)
Quantitative estimations of zoosporic fungi in the environment have historically received little attention, primarily due to methodological challenges and their complex life cycles. Conventional methods for quantitative analysis of zoosporic fungi to date have mainly relied on direct observation and baiting techniques, with subsequent fungal identification(More)
During a survey of mucoralean fungi from a Cerrado reserve (Brazilian savanna) some isolates of a Mucor-like fungus were isolated from soil plates. Characterization based on morphological, physiological and molecular data from translation elongation factor (EF-1α), 28S (D1/D2) and ITS1-5.8S-ITS2 rDNA sequences was made. The isolates produce lateral branches(More)
Zoosporic organisms are commonly found in different aquatic ecosystems; however little is known about the influence of environmental factors and seasonal fluctuations on their occurrence and distribution. This study investigated patterns of abundance, frequency and diversity of these organisms and their relationship with some abiotic factors and seasonality(More)
Cerrado (Brazilian savanna) areas present a high number of endemic and unknown species and consequently have been included among the world’s biodiversity hotspots. After a survey of zygomycetes from Cerrado areas of the “Reserva Biológica de Mogi Guaçu” (RBMG) in São Paulo State, we have found a Mucor-like fungus that produces very large sporangiospores and(More)
A survey of Pythium and Phytopythium species was conducted in hydroponics systems located in the metropolitan region of São Paulo and nearby cities, SP, Brazil. Different samples including water from artesian well, nutrient solution, substrates used for seedlings production and roots of hydroponically grown crops were collected and baited for Pythium and(More)
Halophytophthora spp. are considered as one of the most important decomposers of fallen mangrove leaves worldwide. The knowledge of the diversity of straminipiles in Brazilian mangrove swamps is very limited, and there are no previous descriptions of Halophytophthora species for Brazil. Our aim was to identify and describe the specimens isolated from fallen(More)
