A field investigation of olive trees in Istria, Croatia, revealed branch dieback and cracked bark. Samples of diseased branches were collected from eight different locations and analysed. Additionally, meteorological data from two locations were analysed to determine if there was a connection between climatic changes and the appearance of pathogens in the region. Pathogenicity tests were conducted on olive seedlings. This study provides a description of Biscogniauxia and Sordaria species’ morphology and elucidates their phylogeny based on the internal transcribed spacer (ITS), beta-tubulin (TUB2) and translation elongation factor 1-alpha (TEF1- α) regions. This research represents the first documented occurrence of Biscogniauxia mediterranea causing charcoal disease in olive trees in Croatia. Additionally, it is the first report of Biscogniauxia nummularia (Bull.) Kuntze and Sordaria fimicola causing diseases in olive trees anywhere in the world. Furthermore, this study marks one of the initial forays into molecular investigations of these species isolated from olive trees. Considering the potential threat posed by the inherent aggressiveness of Biscogniauxia species, further research is deemed necessary to curb the development of charcoal disease.

“…These weakened trees are predisposed to secondary infection through branch stubs and other wounds (Inácio et al, 2011). The infection and mortality rate caused by charcoal fungus were 69 and 3% per year, respectively, in the Hyrcanian forests (these values related to the study that was conducted in the east part of Hyrcanian forests of Iran) (Karami et al, 2018). Oak charcoal fungus may cause irreversible damages to the wood quality and subsequently to the forest (Inácio et al, 2011;Henriques et al, 2014).…”

“…Several pathogen and insects species have caused extensive tree mortality in Hyrcanian forests (Hajizadeh et al, 2016), including oak charcoal disease [Biscogniauxia mediterranea (De Not.) Kuntze], and brown alder leaf beetle [Galerucella lineola Fabricius] (Sadeghi et al, 2004;Karami et al, 2018). Tohidifar et al (2016) noted that since 1950, the total area of Hyrcanian forests has declined from 2,750,000 ha to 1,850,000 ha (32.7%) due to a wide range of perturbation (anthropogenic and biological disturbances).…”

“…Higher diversity may lead to greater stability and resistance (Elton, 1958;Tilman and Downing, 1994;McCann, 2000;Tilman et al, 2006;Moore et al, 2011). It is also important to understand the resistance and resilience of the Hyrcanian forests, given the magnitude of the damage of alder beetle and oak fungus outbreaks, and the economic significance of the host trees (Sadeghi et al, 2004;Karami et al, 2018).…”

Biological disturbances are integral to forest ecosystems and have pronounced effects on forest resistance, resilience, and diversity. The Hyrcanian mixed forest, in northern Iran, is at risk of declining resistance, resilience, and diversity due to ongoing pressure from land use change, harvesting, and biological disturbances. We analyzed the resistance and resilience of this area under two biological disturbances (i.e., oak charcoal fungus, Biscogniauxia mediterranea, and alder leaf beetle, Galerucella lineola) and in concert with proposed harvesting. We used a simulation modeling approach whereby we simulated 12 combinations of biological disturbances and harvesting scenarios using the LANDIS-II landscape change model. We estimated the correlation between forest resistance and resilience and tree species diversity to harvesting and biological disturbance. We analyzed the full species composition and age class for 30 and 100 years after disturbances in order to assess resistance as the change in species composition over time. We considered resilience as the ability to recover from a disturbance back to a similar initial state. Results indicate a positive effect of biological disturbances and harvesting on diversity. Our simulations resulted in a negative relationship between diversity-resistance and diversity-resilience within high diversity areas. Our simulation of the Hyrcanian forest reveals that harvesting and biological disturbances, as tested, fulfill the goal of maintaining forest diversity. However, increasing diversity does not always follow by increasing forest resistance and resilience. Scenarios with oak charcoal fungus, both with and without harvesting indicate the lowest decrease in resilient and resistant.

“…In particular, a cork oak endophytic strain of Trichoderma citrinoviride produces peptaibols capable of inhibiting cork oak pathogens’ in vitro growth [ 20 ]. Spray suspensions of T. atroviride and T. viride combined with sanitation and scarification practices were recently suggested for decreasing charcoal disease incidence in Q. castaneifolia trees [ 21 ]. In the present study, we hypothesize that cork oak fungal endophytes are able to control cork oak pathogens’ ( B. mediterranea and D. corticola ) growth and we intend to highlight the most promising cork oak endophytes to be used as a biocontrol strategy.…”

An increase in cork oak diseases caused by Biscogniauxia mediterranea and Diplodia corticola has been reported in the last decade. Due to the high socio-economic and ecologic importance of this plant species in the Mediterranean Basin, the search for preventive or treatment measures to control these diseases is an urgent need. Fungal endophytes were recovered from cork oak trees with different disease severity levels, using culture-dependent methods. The results showed a higher number of potential pathogens than beneficial fungi such as cork oak endophytes, even in healthy plants. The antagonist potential of a selection of eight cork oak fungal endophytes was tested against B. mediterranea and D. corticola by dual-plate assays. The tested endophytes were more efficient in inhibiting D. corticola than B. mediterranea growth, but Simplicillium aogashimaense, Fimetariella rabenhorstii, Chaetomium sp. and Alternaria alternata revealed a high potential to inhibit the growth of both. Simplicillium aogashimaense caused macroscopic and microscopic mycelial/hyphal deformations and presented promising results in controlling both phytopathogens’ growth in vitro. The evaluation of the antagonistic potential of non-volatile and volatile compounds also revealed that A. alternata compounds could be further explored for inhibiting both pathogens. These findings provide valuable knowledge that can be further explored in in vivo assays to find a suitable biocontrol agent for these cork oak diseases.
