Phytophthora quercina is a papillate homothallic soil-borne plant pathogen causing root rot of oak tree species in Europe.[1] It is associated with necrotic fine roots.[2]
In culture, this species shows a uniform, dome-shaped and cottonwool-like colony growth pattern. It also frequently presents sympodially branched primary hyphae, a high proportion of elongated, ellipsoid or ovoid oogonia, the absence of amphigynous antheridia. Its sporangia vary greatly in size and shape.[2]
Its name derives from Greek Phytophthora φυτόν (phytón), “plant” and φθορά (phthorá), “destruction” and quercina stems from the affected genus, Quercus.
