“…Diaporthe (anamorph: Phomopsis) species have often been reported as plant pathogens, non-pathogenic endophytes or saprobes, commonly isolated from a wide range of hosts (Kowalski and Kehr 1992;Sieber 2007;Gomes et al 2013).

“…This depends on specialization and adaptation in Diaporthe/Phomopsis. Some species of this complex can be therefore either harmless endophytes or pathogenic depending on the host health status (Uecker 1988;Gomes et al 2013). Diaporthe/Phomopsis fungi have often been classified as host specific (Udayanga et al 2011;Gomes et al 2013).…”

F. excelsior is affected by dieback in the major part of its natural geographical range in Europe, which results in economic and ecological losses. The disease is caused by the ascomycetous fungus Hymenoscyphus fraxineus, a pathogen introduced to Europe most probably from East Asia. This paper presents data on fungi identified on F. excelsior trees representing two different stages of ash dieback in Poland. Fungal communities were identified in initial necrotic lesions on living stems and twigs using the classical method of isolation on malt extract agar and morphological and molecular analyses. In dead apical parts of stems and twigs, fungi were identified by microscopic analyses of fruit bodies formed in situ. Seventy-one fungal taxa were found in 720 samples with symptoms of initial or advanced necrosis. The most common fungus detected in initial necrotic lesions in each forest site was Hymenoscyphus fraxineus (59.2 % of analysed samples). Other frequently isolated fungi included Alternaria alternata, Diaporthe eres, Diplodia mutila, Fusarium avenaceum, F. lateritium and Phomopsis spp. Fruit bodies on dead apical parts of stems and twigs were produced mostly by Diaporthe eres, Diplodia mutila, Lophiostoma corticola, Phomopsis spp., Sirodothis sp. and Valsa cypri. Fungal communities from different sites were similar, as shown by high Sørensen similarity index values. Greatest variation in fungal community structure at the initial necrotic stage was realized by D. mutila and F. avenaceum, and at the advanced necrotic stage by D. eres, D. mutila and Phomopsis spp. Data show a close affinity of certain fungi to site, suggesting geographical relatedness. The ecological effects of distribution of the invasive H. fraxineus and of other fungi sporulating on diseased ash trees in Europe are discussed.

Abstract. Phomopsis vaccinii cause a serious disease of blueberry, cranberry and other Vaccinium crops in the North America and Europe as well. Over 1000 species names are described by Phomopsis spp., but their biology and life style are mostly unknown. Identification of P. vaccinii by methods of classical phytopathology is difficult and complicate, because many species are morphologically similar to P. vaccinii, and P. vaccinii itself has diverse patterns of colony morphology. For this investigation P. vaccinii isolates were obtained from five cranberry plantations in different locations of Latvia (Babite, Alsunga, Rucava, Ape and Pargauja municipality) from berries affected by viscid rot at harvest and storage in 2010. Altogether 44 P. vaccinii isolates were cultivated on potato dextrose agar for description of colony morphology. In order to find some relationships between samples, the isolates were arranged in different groups on the basis of mycelium color and structure (zoning), reverse pigmentation, pycnidium formation time, size, location, number and size of conidia. During this study the colonies of P. vaccinii from cranberry in Latvia showed different morphological features in culture and no relationships between growing regions and groups of isolates were found. P. vaccinii is easy to confuse with other Phomopsis species if only classical phytopathological methods are used.

The objective of this study was to study the diversity of endophytic fungi isolated from Ceiba pentandra and to isolate their bioactive chemical compounds. The methodology used during this study consisted in isolating endophytic fungi from the bark of C. pentandra on Potato Agar. The isolates obtained were identified on the basis of the ITS regions of their ribosomal DNA. Antibacterial screening of the mycelium of endophytic fungi isolated was evaluated against multidrug‐resistant E. coli and S. aureus strains. This screening led to the selection of isolates EC 321 and EC 28 for their ability to effectively inhibit the growth of the bacterial strains tested. EC 321 was grown and fermented on rice medium. Secondary metabolites were extracted with ethyl acetate. From the crude extract, secalonic acid A was isolated and identified by chromatographic and NMR. The in vitro activity of secalonic acid A against the growth of multiresistant bacterial strains was evaluated. Secalonic acid A was active against all multidrug‐resistant bacterial strains E. coli 942, E. coli 4814, S. aureus 931, S. aureus 934, S. aureus MRSA 1872 and K. pneumonia 815 with respective MICs of 18.75; 18.75; 18.75; 4.7; 37.5 and 37.5 μg/mL.
