| Water used in hydrotherapy units of Nova Iguaçu and Nilópolis, Rio de Janeiro State, Brazil, was microbiologically analyzed. Thirty samples (5ml each) were weekly collected from September 2001 to June 2002 before the beginning and after the end of activities in the units. For analysis, routine techniques were used, which showed the presence of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella spp, Candida spp, Penicillium spp, Epidermophyton spp, Aspergillus fumigatus, Aspergillus niger, Aspergillus spp, Cephalosporium spp, Cladosporium spp, Trichophyton rubrum, and Trichophyton spp. Results indicated a need for improving hygienic conditions, suggesting that water might be a contamination source in the evaluated units. |

| Eighteen isolates sampled from sugar beet roots associated with an unknown etiology were characterized based on observations of morphological characters, hyphal growth at temperatures ranging from 4 to 28 C, production of phenol oxidases, and sequence analysis of internal transcribed spacer (ITS) and large subunit (LSU) regions of the ribosomal DNA (rDNA). The isolates did not produce asexual or sexual spores, had binucleate hyphal cells with clamp connections, grew from 4 to 22 C with and estimated optimal growth at 14.5 C, and formed a dark brown pigment on potato dextrose or malt extract agar amended with 0.5% tannic acid. Color changes observed when solutions of gum guiac, guiacol, and syringaldzine were applied directly to mycelium grown on these... |

| Resistance to rhizomania is a basic requirement for cultivars’ approval for commercialization. The objectives of this research were to identify germplasm accessions that carry resistance genes to rhizomania and storage root rots. Twenty-one sugar beet (Beta vulgaris L.) germplasm from the USDA-ARS Kimberly sugar beet program and four check cultivars were screened for resistance to Beet necrotic yellow vein virus (BNYVV) during the 2011 growing season and during the 2011/2012 storage period for fungal growth in an indoor storage. The rhizomania evaluation was conducted at the rhizomania nursery in the USDA-ARS North Farm in Kimberly, ID. The crop was managed according to standard cultural practices and pest control. The plots were rated twice (4 weeks... |

| Root rots in sugar beet storage can lead to multi-million dollar losses because of reduced sucrose recovery. Thus, studies were conducted to establish better chemical control options and a better understanding of the fungi involved in the rot complex. A water check and three fungicides (Mertect, Propulse, and Stadium) were investigated for their ability to control fungal rot on sugar beet roots held in long term storage during both the 2012 and 2013 storage seasons. At the end of September into October, roots were collected on 5 subsequent weeks, treated, and placed on top of a commercial indoor storage pile until early February. Differences (P <0.0001 to 0.0150) between spray treatments were evident with both Propulse and Stadium reducing fungal growth... |

| Ustilaginomycotina (Basidiomycota, Fungi) has been reclassified recently based on multiple gene sequence analyses. However, the phylogenetic placement of two yeast-like genera Malassezia and Moniliella in the subphylum remains unclear. Phylogenetic analyses using different algorithms based on the sequences of six genes, including the small subunit (18S) ribosomal DNA (rDNA), the large subunit (26S) rDNA D1/D2 domains, the internal transcribed spacer regions (ITS 1 and 2) including 5.8S rDNA, the two subunits of RNA polymerase II (RPB1 and RPB2) and the translation elongation factor 1-α (EF1-α), were performed to address their phylogenetic positions. Our analyses indicated that Malassezia and Moniliella represented two deeply rooted lineages within... |

| Stripe smut of grasses, Ustilago striiformis s.l., is a complex of smut fungi widely distributed over temperate and subtropical regions. The disease results in the shredding and death of leaf tissue following the rupture of elongated sori. Nearly 100 different grass species in more than 30 genera are infected by stripe smut. During the last two centuries more than 30 smut taxa have been described from members of this complex. The present study attempts to clarify the taxonomy and phylogeny of stripe smuts on grasses by analysing both morphological and molecular data. More than 200 specimens from different continents and host plants were examined. DNA was extracted from teliospores of 23 specimens from different hosts collected in Europe, Asia, and North... |

| Clavaria species with dark basidiomata occurring in Europe were analysed using morphological and molecular methods. Morphological analyses revealed four groups containing seven Clavaria species with dark basidiomata. Phylogenetic analysis of the LSU nrDNA region confirmed the separate positions of all seven Clavaria species within the genus. All sequences were grouped in four well-supported clades, mostly corresponding to defined morphological species. The results of the molecular study are inconsistent with the infrageneric classification of Clavaria based on the presence or absence of clamps on the bases of basidia and two widely accepted subgenera. Clavaria and Holocoryne appear to be polyphyletic. A new approach in species delimitation is presented: 1)... |

| 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... |

| Actualmente existen escasos trabajos sobre la influencia de las lluvias en la distribución de los hongos presentes en los ecosistemas marinos. Este estudio tiene como objetivo conocer la distribución de los hongos marinos en los meses de junio (lluvioso) y marzo (seco) del año 2000, en dos playas ubicadas al norte de Ciudad de la Habana. Se empleó la metodología de incubación de sustratos vegetales en cámara húmeda y los hongos aislados se clasificaron hasta nivel de especie. Se obtuvieron un total de 82 aislamientos, de los cuales el 87.6 % corresponden a hongos ascomicetos y el 13.4% a hongos mitospóricos. Corollospora marítima y Lindra marinera fueron las especies más frecuentes, con 26.8% y 17%, respectivamente. En junio el número de aislamientos de... |

| El Basidioliquen Cora montana (Sw.) R.Sant disminuye y aumenta su peso en relación con la hidratura de la atmósfera, como muestra la fig 1. La transpiración relativa // de 100o/o. En 25°C el talo del liquen está en equilibrio con una humedad relativa de 85o/o. El máximo contenido de agua es de 25o/o. Si se brota el liquen en aire húmedo, la fotosíntesis alcanza su máximo mayor de 1 ml CO2/h/g, después de 1 hora y con una pérdida de agua aproximada de 25o/o (fig.). En agua, el máximo se alcanza un poco más tarde y es más bajo (fig.3). Entre más tiempo el liquen permaneció en estado seco, más se demora en alcanzar valores positivos de asimilación (fig.4). Los valores máximos de fotosíntesis encontrados, son similares a los de otros líquenes. Después de 3-4... |

| Por primera vez se realizó la identificación de hongos marinos filamentosos aislados en cuatro playas del litoral sur de la provincia de Guantánamo, Cuba. Para el aislamiento de los hongos se empleó el método indirecto de incubación de sustratos vegetales en cámara húmeda. Se describieron 25 especies de hongos marinos: 18 ascomicetes, seis hongos mitospóricos y un basidiomiceto. De las especies descritas, seis constituyen nuevos registros para el país. Con estos resultados, el número total de hongos marinos superiores reportados para Cuba es de 44. |
