European forests are threatened by increasing numbers of invasive pests and pathogens. Over the past century, Lecanosticta acicola, a foliar pathogen predominantly Pinus spp., has expanded its range globally, is in impact. acicola causes brown spot needle blight, resulting premature defoliation, reduced growth, mortality some hosts. Originating from southern regions North American, it devastated USA's states early twentieth 1942 was discovered Spain. Derived Euphresco project 'Brownspotrisk,' this study aimed to establish current distribution species, assess risks L. forests. Pathogen reports literature, new/ unpublished survey data were combined into an open-access geo-database (http://www.portalofforestpathology.com), used visualise pathogen's range, infer climatic tolerance, update host range. species have now been recorded 44 countries, mostly northern hemisphere. The type increased recent years, present 24 out 26 countries where available. Other largely restricted Mexico Central America, recently Colombia. records demonstrate that tolerates wide climates across hemisphere, indicate potential colonise spp. large swathes Europe. Preliminary analyses suggest could affect 62% global area end under climate change predictions.
