Ciri dan struktur

The fungus forms mycelium on the undersides of the leaves of its hosts. As with most Erysiphaceae, Phyllactinia corni is highly host-specific, infecting only plants in the genus Cornus. Furthermore, both its geographical and host range may be significantly smaller than that given by Braun and Cook (2012), as records from North America and Europe may both pertain to different, undescribed species. Phyllactinia corni can be found in any habitats where its host species occur, including urban and suburban gardens and parks. Its reported host range includes Cornus alba, alternifolia, amomum, asperifolia, canadensis, florida, foemina, glabrata, mas, nuttallii, obliqua, officinalis, racemosa, rugosa, sanguinea, sericea. Many other species of powdery mildew also occur on Cornus, including one other species of Phyllactinia: Phyllactinia cornicola, known solely from Pakistan. The mycelium is hypophyllous (found on leaf undersides) and sometimes covers the entire surface. The hyphal appressoria are nipple-shaped, rod-shaped or lobed and occur both solitarily and in opposite pairs. Conidophores arise centrally from their mother cell. They have very long foot cells that are straight with a basal septum generally not elevated. The conidiophores produce single conidia. Conidia are clavate with a rounded apex, and can be faintly pigmented. The chasmothecia (fruiting bodies) have 5–16 straight, pointed appendages around the equator, which have a bulbous basal swelling. The peridium of the chasmothecia has cells of irregular shape. Phyllactinia corni has two spores per ascus which are roughly ellipsoid and at first faintly olive-coloured, becoming colourless.

Habitat dan peran ekologis

Phyllactinia corni is a species of powdery mildew in the family Erysiphaceae. It is found in North America and Eurasia where it infects plants in the genus Cornus (dogwoods). The fungus forms mycelium on the undersides of the leaves of its hosts. As with most Erysiphaceae, Phyllactinia corni is highly host-specific, infecting only plants in the genus Cornus. Furthermore, both its geographical and host range may be significantly smaller than that given by Braun and Cook (2012), as records from North America and Europe may both pertain to different, undescribed species. Phyllactinia corni can be found in any habitats where its host species occur, including urban and suburban gardens and parks.
