Phytophthora kernoviae spread via the air to the bark of tree species, with the European beech tree ("Fagus sylvatica)" being especially susceptible. As of 2005, it was confined to a relatively small area of Cornwall but has also been found in Wales and Cheshire suggesting that the pathogen may be being spread by the horticultural trade. Due to the national and international demand of these plant products, "Phytophthora kernoviae" has initiated recent concern after being found "Vaccinium myrtillus", commonly called Bilberry. This pathogen causes significant necrosis on leaves, bleeding stem lesions, and stem dieback as the primary symptoms, which occur at an
Luzula sylvatica fruit is a 3-valved capsule containing three oblong seeds. Each seed is indistinctly reticulate, often with a caruncle (a basal or apical appendage); seeds tend to germinate close to their parent plant. "Luzula sylvatica" has a wide distribution, and is native to Europe (the European temperate element of flora ) and southwest Asia - including the British Isles where "L. sylvatica" populations are widespread stable, apart from a decline in central and south east England. There is one record of "L. sylvatica" from Washington State, United States of America. Usually growing in partial to full shade, "Luzula sylvatica" tends to
