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 least greenish throughout winter. The leaves can also help to differentiate the plant from similar-looking plants in the closely related genus "Juncus", as scattered white hairs can be found along the leaf edges. Its tepals are , with flowers which grow in groups of 3 or 4. From mid-spring to summer, "L. sylvatica " produces flowers in open panicles which are very small, chestnut-brown in colour and can be found in dense and lax clusters. "L. sylvatica" is sometimes stoloniferous. "Luzula sylvatica" is both anemophilous and entomophilous, in that it can be pollinated by either wind or insect. "L. sylvatica"'s
