Oaks are dominant and key tree species in Mediterranean forest ecosystems. However, recent decades, oak forests have been heavily impacted by decline, a worldwide phenomenon exacerbated climate change. The charcoal disease agent Biscogniauxia mediterranea is involved the decline of formations variety contexts. Here, we investigated impact role B. oaks Castelfidardo Forest, relict wood late Holo...

Chestnut blight, Cryphonectria parasitica (Murrill) Barr, was reported in Portugal 1989. The disease rapidly spread within the chestnut region of Trás-os-Montes (the Northeast Portugal). Eradication and mechanical/burning exclusion failed to control natural hypovirulence is still absent or very low incidence. introduction human-assisted therapeutic therefore required disease.

The empirical observation of the impacts drought and heat waves that occurred between 2017 2022 in several forest areas Tuscany allowed to describe various processes effects on trees shrubs. most severe were observed evergreen Mediterranean tall woodlands aged coppices (on holm oak trees), causing defoliation even mortality. In cases, attempts resprouting from dormant buds (from base tree trunk...

Field surveys in Zagros forests located in western Iran were done to study some aspects of biology and host range of Biscogniauxia mediterranea during 2014-2016. The ability of its conidia and ascospores to cause the disease was evaluated under greenhouse condition. Ascospore viability and development of anamorph and teleomorph were surveyed under different conditions. The pathogen host range w...

Xylariomycetidae (Ascomycota) is a highly diversified group with variable stromatic characters. Our research focused on inconspicuous xylarialean taxa from China, Italy, Russia, Thailand and the United Kingdom. Detailed morphological descriptions, illustrations combined ITS-LSU-rpb2-tub2-tef1 phylogenies revealed 39 our collections belonging to Amphisphaeriales Xylariales. A new family (Appendi...
