Its name derives from Greek "Phytophthora" (), “plant” and (), “destruction”; “the plant-destroyer” and "plurivora" and from Latin ( = many, - = feeding). Phytophthora pseudosyringae Phytophthora pseudosyringae is a semi-papillate homothallic soil-borne plant pathogen causing root and collar rot of deciduous tree species in Europe. It is associated with necrotic fine roots and stem necroses of "Fagus sylvatica" and "Alnus glutinosa", and isolates are moderately aggressive to fine roots of oaks and beech ("Nothofagus"), highly aggressive to holly leaves and apple fruits, and slightly pathogenic to alder bark. It belongs to the class
Luzula sylvatica grow on acidic soils in damp habitats. "L. sylvatica" can be found on stream banks and well-drained, open woodland, as well as in open ground and rock ledges and peaty heath moors. Despite its preference for acidic soils, it can tolerate most soil pH levels. The leaves of "Luzula sylvatica" are picked in winter by golden eagles to line their eyries. The flowers and seeds of "L. sylvatica" are also the sole food source for the larvae of the "Coleophora sylvaticella" moth. "Luzula sylvatica" is commonly used in horticulture — its thick, patch-forming habit (which allows the plant to act
