Chalara fraxinea is an invasive pathogen in France [PDF]

European Journal of Plant Pathology, 2011
Decline induced by Chalara fraxinea is an emerging disease that severely affects ash stands in Europe. The disease appears to have an invasive spread from East to West of Europe in the last decade. The teleomorphic stage, Hymenoscyphus pseudoalbidus, that occurs as apothecia on ash rachis in the litter was recently described.

The introduction of Hymenoscyphus fraxineus to Northern Ireland and the subsequent development of ash dieback

Forest Pathology, Volume 53, Issue 1, February 2023., 2023
Abstract Ash dieback caused by Hymenoscyphus fraxineus was first recorded in Northern Ireland (NI) in November 2012. The disease was observed only on recently (<6 years) planted trees. An in‐depth case study in 2015 of an ash plantation with severe symptoms indicated that many of the trees were infected at the time of planting.
