25. Brazilian tropical dry forest (Caatinga) in the spotlight: an overview of species of Aspergillus, Penicillium and Talaromyces (Eurotiales) and the description of P. vascosobrinhous sp. nov.
ABSTRACT A literature-based checklist of species of Aspergillus, Penicillium, and Talaromyces recorded in the Brazilian tropical dry forest (Caatinga), the largest tropical dry forest region in South America, is provided. A total of 130 species (60 Aspergillus, 57 Penicillium, and 13 Talaromyces) are reported. Soil was the most common substrate, with 122 spe

26. Late defoliation of ‘Chardonnay’ grapevine in subtropical highland climate
ABSTRACT Chardonnay cultivar has shown great potential of planting and development in sites above 900m of Brazilian southeast for sparkling wines production. The quality of this product is related to vineyard climate and management, since both affect the vine development and grape composition. In this study, three defoliation orientations (east, west and eas

27. EVALUATION OF THE METABOLIC PRODUCTION OF THE ENDOPHYTIC FUNGUS Phomopsis sp.
Endophytic microorganisms have been shown to be an important source of bioactive compounds, and much has been studied about their metabolites. For example, compounds with different biological activities have been isolated from Phomopsis sp. The metabolic study of this genus may lead to a better understanding of the routes of production of metabolites of inte

28. Biosorption Potential of the Aspergillus sp. and Insights into Secondary Metabolism in the Presence of Copper and Lead
The fungus Aspergillus sp. was isolated from copper mining rejects and cultured in a liquid culture medium (potato dextrose, PD) enriched with CuSO4.5H2O and Pb(NO3)2 in different concentrations. By flame atomic absorption spectrometry (FAAS) it was observed that fungus absorbed 86% of both copper and lead, with initial concentrations of 100, 500 and 1000 mg

29. Therapeutic failure with itraconazole in sporotrichosis due to bariatric surgery,
Abstract Sporotrichosis is a deep mycosis of subacute or chronic evolution, caused by the dimorphic fungus of the genus Sporothrix. The treatment is carried out with antifungal orally or intravenously. Therapeutic success can be affected by several factors, such as altered gastrointestinal physiology by surgery. More and more patients are submitted to bariat

30. Aromatic Polyketides and Macrolides from Microsphaeropsis arundinis
The endophytic fungus Microsphaeropsis arundinis was isolated from the capitula of the tropical plant Paepalanthus planifolius (Eriocaulaceae). The fungus was cultivated in seven different media, and the ethyl acetate extracts were tested against tumor cell lines using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide MTT assay. The culture wa

31. Monitoring Pyricularia sp. airborne inoculum in Passo Fundo, Rio Grande do Sul, Brazil
RESUMO O fungo Pyricularia sp. agente causal da brusone do trigo, produz conídios hialinos, secos e leves que podem ser removidos das lesões esporulativas pelo vento, e transportados a longas distâncias. Foram conduzidos experimentos com o objetivo de determinar (a) a relação entre variáveis meteorológicas e a quantidade de conídios de Pyricularia sp

32. Chemical control of leaf-cutting ants: how do workers disperse toxic bait fragments onto fungus garden?
ABSTRACT Leaf-cutting ants are controlled with toxic baits. For the method’s greater efficiency, the baits must be distributed and processed by workers during fungus cultivation. To test hypotheses whether the mode of action of the active ingredients, which blocks the sodium channels and interrupts the production of ATP in the mitochondria, interferes with

33. Ephebe brasiliensis (Ascomycota, Lichinaceae): an overlooked freshwater lichenized fungus
Resumo Ephebe brasiliensis é um cianolíquen fruticoso e semiaquático que ocorre em ambientes de água doce do Brasil e Uruguai. Embora essa espécie possa ser localmente abundante e apresente uma ampla distribuição geográfica, ela ainda é pouco estudada e permanece incompreendida. Nesse artigo, E. brasiliensis é registrada pela primeira para o Sul do

34. Colletotrichum nymphaeae var. entomophilum var. nov. a natural enemy of the citrus scale insect, Praelongorthezia praelonga (Hemiptera: Ortheziidae)
ABSTRACT: The citrus scale insect Praelongorthezia praelonga (Douglas), a major pest of citrus and other economically important crops, has only two commonly documented natural enemies: an entomopathogenic strain of the fungus Colletotrichum nymphaeae (Pass.) Aa and several parasitoids. The entomopathogenic strain of C. nymphaeae, formerly recognized under th

35. Expression Analysis of Pyrenophora teres f. maculata-Responsive Loci in Hordeum vulgare
Abstract Pyrenophora teres f. maculata is the causal agent of barley spot form net blotch (SFNB), a major stubble-borne disease in many barley-growing areas worldwide. In plants, the Nucleotide-Binding Site-Leucine-Rich Repeat (NBS-LRR) gene family functions in immunity against a variety of pathogens and pests. From a pre-established set of NBS-type resistan

36. Chromoblastomycosis caused by Rhinocladiella aquaspersa: first case report in Guatemala
Abstract The authors report a case of 40-year-old male patient with a five-year history of chromoblastomycosis on his right leg. Diagnosis was performed by direct 40% KOH exam of skin scales, culture with micro- and macromorphologic analysis, and genotypic characterization (sequencing of a fragment of the ITS region and phylogenetic analysis) of the isolated
