Marssonina rosae (Lib.) Died. 1915

Type: Foliicolous Fungi; Description: Conidiomata acervular, scattered, subcuticular, erumpent, oval to elliptical, brown; on circular dark brown to black leaf spots with ragged margins, up to 15 mm in diameter, on upper surfaces of leaves. The black colour is due to a dense subcuticular network of dark hyphae. Conidia oval to elliptical, 1-septate, 20–25 × 5–6 μm, smooth, hyaline.
Distribution: Auckland, Waikato, Bay of Plenty, Taranaki, Taupo, Wanganui, Wellington, Nelson, North Canterbury, Mid Canterbury, Chatham Islands.; 1st Record: Kirk (1901: as ‘black spot’).
Significance: The cause of ‘black spot’ of roses, recorded by Dingley (1969) as a common disease throughout the country. Heavy infection causes considerable defoliation, seriously weakening the plants. In all except very dry areas, fungicidal control is usually necessary.; Host(s): Rosa spp.
