| ABSTRACT The aim of this study was to investigate the species of conidial fungi associated with leaf litter of Cedrela odorata (Meliaceae), an endangered red cedar species typical of Amazonian terra-firme forests. Conidial fungi were sampled around C. odorata individuals in three forest areas in the municipality of Belém (Pará State, Brazil). A total of 104 species were identified, with 53 new records for the state of Pará, 46 first records for the Brazilian Amazon, including new records for Brazil (Cordana abramovii), for South America (Acarocybiopsis cubitaensis, Xylocladium claviforme) and for the Americas (Dactylaria biguttulata). A review of species of conidial fungi reported on C. odorata is provided, indicating its distribution in Brazil. For each... |

| Visando ampliar o conhecimento sobre diversidade de fungos conidiais, 10 folhas mortas de três indivíduos de C. melchiorii e de C. nemorosa foram coletadas bimestralmente na Serra da Jibóia, Bahia, no período de outubro/2005 a junho/2006. As folhas foram lavadas em água corrente e mantidas em câmara-úmida durante 30 dias. As estruturas fúngicas foram retiradas para estudo morfológico. Foram identificados 79 táxons de Ascomycota na forma anamórfica. Destes, 78 são hifomicetos e um celomiceto. Do total, 87% ocorreram sobre C. melchiorii e 55% sobre C. nemorosa. A maioria dos fungos apresentou freqüência esporádica e constância acidental. As espécies mais freqüentes foram: Beltrania rhombica Penz., Chaetopsina fulva Rambelli, Dactylaria ficusicola Paulus,... |

| ABSTRACT Lichens play a key role in natural ecosystems, as they can function as primary producers, recycle minerals and fix nitrogen. Despite their environmental importance, little is known about lichen ecology in Brazil, and especially about how abiotic factors may influence their spatial distribution. In this study, we aimed to verify how the cover and richness of corticolous lichens on Araucaria angustifolia trunks vary between two different habitats (Forest and Grassland). The photoquadrat sampling method was applied to A. angustifolia trunks. The Coral Point Count software with Excel extensions (CPCe) was used to analyze photographs for lichen cover and richness. Additionally, a redundancy analysis was conducted to estimate how five abiotic and two... |

| ABSTRACT This study presents the description of Phaeosphaeria deschampsii, which was found in plant communities from Half Moon Island, South Shetland Archipelago, Antarctica, in February 2014. Many patches of Deschampsia antarctica (Poaceae), the only indigenous Poaceae specie in Antarctic, were found dead, parasitized by a fungi pathogen. Based on the shape of its perithecia, with oblique neck, erumpent in the grass tissues, ascospore form and septation, the specie was identified as new to science. |

| Durante un estudio de la biodiversidad de micromicetes que crecen en la corteza y madera de Podocarpus parlatorei, se encontraron cuatro especies de Lophiostoma y una quinta especie, Sigarispora caulium. Lophiostoma punctatum posee una combinación única de caracteres morfológicos y se describe como una nueva especie. Lophiostoma macrostomum, L. quadrinucleatum, L. vicinum y Sigarispora caulium se citan por primera vez para la Argentina. Se presentan descripciones, ilustraciones, comentarios, datos de distribución geográfica, hábitat y una clave dicotómica para las especies de Lophiostoma y Sigarispora conocidas sobre Podocarpus parlatorei en Argentina. |

| Attine ants are a monophyletic group comprising more than 230 species, distributed exclusively in the New World. All higher Attini ants depend on the cultivation of fungus gardens for food, and those gardens are continuously exposed to alien microorganisms. The present work describes, for the first time, the composition, relative frequency and the richness of the fungal species comprising the mycobiota from the garden of the most abundant Acromyrmex species from different regions of Argentina. We also compared, using a multivariate approach, the mycobiota composition with the purpose of testing two hypotheses: 1) whether mycobiota is defined by the ant species, or 2) whether mycobiota is determined by the geographical region. We found that each fungal... |

| Based on type studies and freshly collected material we here re-instate the genus Thyronectria (Nectriaceae, Hypocreales). Species of this genus were recently for the most part classified in the genera Pleonectria (Nectriaceae) or Mattirolia (Thyridiaceae), because Thyronectria and other genera had been identified as members of the Thyridiaceae due to the presence of paraphyses. Molecular phylogenies based on several markers (act, ITS, LSU rDNA, rpb1, rpb2, tef1, tub) revealed that the Nectriaceae contain members whose ascomata are characterised by long, more or less persistent, apical paraphyses. All of these belong to a single genus, Thyronectria, which thus has representatives with hyaline, rosy, green or even dark brown and sometimes distoseptate... |

| The xylariaceous genus Rhopalostroma comprises a small conglomerate of stromatic, angiospermassociated pyrenomycetes, which have so far exclusively been reported from the palaeotropics, above all from tropical Africa and South Asia. Morphological and chemotaxonomic studies had suggested their close relationship to the genera Daldinia and Hypoxylon. However, those results were mainly based on herbarium specimens, and no molecular phylogenetic data were available on Rhopalostroma. During a foray in Côte d’Ivoire, fresh material of R. angolense was collected, cultured and studied by microscopic methods and by secondary metabolite profiling using high performance liquid chromatography coupled with diode array and mass spectrometric detection. In addition, ITS... |

| The genera Microascus and Scopulariopsis comprise species commonly isolated from soil, decaying plant material and indoor environments. A few species are also recognised as opportunistic pathogens of insects and animals, including humans. In the past, the taxonomy of these fungi has been based on morphology only. With the aim to clarify the taxonomy and phylogeny of these fungi, we studied a large set of clinical and environmental isolates, including the available ex-type strains of numerous species, by means of morphological, physiological and molecular analyses. Species delineation was assessed under the Genealogical Phylogenetic Species Recognition (GCPSR) criterion using DNA sequence data of four loci (ITS region, and fragments of rDNA LSU, translation... |
