“…Their dimensions are 17.6 (13.5-21.6) × 7.7 (6.8-9.5) μm. These dimensions exceed those indicated by Ragazzi et al (2012) for B. mediterranea on Fraxinus excelsior in Italy (14.6-20 × 6.99.1 μm), but are similar to those of Zíbarová & Kout (2017) for Quercus cerris in Bulgaria, Corylus avellana and Fagus sylvatica in the Czech Republic (14-21 × 6.5-8.5 μm); Fournier, Magni (2004) for Carpinus betula, Corylus avellana and Fagus sylvatica in France (14-19 × 7-9 μm); Jurc & Ogris (2005) for Quercus cerris in Slovenia (16 (13-19.5) × 7.5 (6-9) μm). Molecular analyses are required for more precise determination of the relationships between different origins of the fungus.…”

“…Symptoms of damage (wet spots, brown colouring) caused by B. mediterranea have been observed on stems, especially in the lower and basal parts, but stroma and fruiting bodies have not been found. Zíbarová & Kout (2017) have determined В. mediterraneа on specimens in the oak herbarium from the Eastern Balkan Mountains, but there is no information about its finding on cork oak.…”

Distribution of Biscogniauxia mediterranea and its potential insect vectors on Quercus suber in Southwestern Bulgaria

This is the first study in Bulgaria on the distribution of Biscogniauxia mediterraneа in cork oak plantations (Quercus suber). Symptoms of the disease (presence of exudate and wounds with stroma) caused by the fungus have been found on stems and branches of cork oak in Maleshevska Mountain. Harvesting of cork does not visibly affect the phytosanitary status of the trees. A significantly higher risk of parasitic fungus development occurs in coppice-managed crops where it causes the death of young trees. The associations of ten insect species with the Quercus suber are new for Bulgaria. Eight of them are possible vectors of the fungus.

“…Little is known about N. aureolutea because it is rarely collected, with a small number of reports from Europe, the continental US, and Hawaii, where it grows in the wood, and sometimes on the outer bark, of Acer, Corylus, Populus, Quercus, and Salix; most collections appear to be from Quercus [61,133]. Our strain may be the first report from Canada; however, N. aureolutea is likely more common than perceived, and some specimens identified as N. aenea are actually N. aureolutea [134].…”

Plant diseases and pests reduce crop yields, accounting for global crop losses of 30% to 50%. In conventional agricultural production systems, these losses are typically controlled by applying chemical pesticides. However, public pressure is mounting to curtail agrochemical use. In this context, employing beneficial endophytic microorganisms is an increasingly attractive alternative to the use of conventional chemical pesticides in agriculture. A multitude of fungal endophytes are naturally present in plants, producing enzymes, small peptides, and secondary metabolites due to their bioactivity, which can protect hosts from pathogens, pests, and abiotic stresses. The use of beneficial endophytic microorganisms in agriculture is an increasingly attractive alternative to conventional pesticides. The aim of this study was to characterize fungal endophytes isolated from apparently healthy, feral wine grapes in eastern Canada that have grown without agrochemical inputs for decades. Host plants ranged from unknown seedlings to long-lost cultivars not widely propagated since the 1800s. HPLC-MS was used to identify unique endophyte-derived chemical compounds in the host plants, while dual-culture competition assays showed a range in endophytes’ ability to suppress the mycelial growth of Botrytis, which is typically controlled in viticulture with pesticides. Twelve of the most promising fungal endophytes isolated were identified using multilocus sequencing and morphology, while DNA barcoding was employed to identify some of their host vines. These fungal endophyte isolates, which consisted of both known and putative novel strains, belonged to seven genera in six families and five orders of Ascomycota. Exploring the fungal endophytes in these specimens may yield clues to the vines’ survival and lead to the discovery of novel biocontrol agents.

“…Kuntze, which had never been recorded in Poland before, was isolated and found to constitute almost 3% of the mycobiota of symptomatic needles. In the Czech Republic this species is considered rare and has been observed on dead and dying wood (Zíbarová & Kout 2017).…”

The European silver fir (Abies alba Mill.) has the largest distribution area of all the European species of fir. It is the only species of this type found in the Carpathian Mts., including their highest range - the Tatras, where it constitutes one of the main components of lower montane forests. In certain sections of the Carpathian Mountains fir stands are affected by the competitive pressure of beech. This may be due to climate change, as well as biotic factors such as plant diseases. One such disease is Herpotrichia needle browning. The goal of the present research was to assess the occurrence of Herpotrichia needle browning in the Tatra National Park and determine the species composition of fungi colonizing symptomatic needles and shoots. Symptoms of the disease were observed across the entire research period, i.e., from May to mid-September 2019. They included the wilting of the needles with subsequent mycelial growth on the remains, as well as shoot deformation. The mycological analysis of the needles and shoots of A. alba resulted in the isolation of 22 fungal taxa. In the case of the needles and shoots, which showed symptoms of infection, the most frequent species of fungus was Sydowia polyspora (Bref. & Tavel) E. Müll., followed by Alternaria alternata (Fr.) Keissl. and Rhizosphaera macrospora Gourb. & M. Morelet. Herpotrichia needle browning seems to be triggered by a complex disease resulting from synergistic interaction of several fungal pathogens
