Microsphaera alphitoides Griffon & Maubl. 1912

Only the conidial stage of the fungus has been collected in New Zealand. Powdery mildew occurs on the english oak throughout New Zealand, especially on young trees oc on regrowth after severe pruning (Gilmour, 1966a). As oak trees are rarely grown in plantations it is of no economic importance.

Microsphaera alphitoides Griffon & Maubl. 1912

Type: Powdery Mildews; Description: Mycelium superficial, moderately dense to dense, white, hyphae 3–5 μm wide; on leaves. Appressoria multi-lobed. Ascomata not known in New Zealand. Conidiophores 40–60 × 6–10 μm, foot cell straight. Conidia produced singly, barrel-shaped, 0-septate, 35–45 × 15–22 μm, smooth, hyaline.
Distribution: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupo, Wanganui, Wellington, Gisborne, Wairarapa, Nelson, North Canterbury, Mid Canterbury, South Canterbury.; 1st Record: Brien & Dingley (1951: as Oidium sp.).
Significance: Oak powdery mildew can be very damaging to nursery stock, coppice shoots, and young leaves, particularly in Quercus robur. The fungus attacks young leaves and occasionally young shoots in spring. Leaves soon become covered with a layer of white mycelium and powdery masses of conidia. In severe attacks, the leaves shrivel, turn brown, and fall. The disease is confined to young leaves. It is not important on older trees but may kill young seedlings in the nursery.; Host(s): Ailanthus altissima, Castanea crenata, C. sativa, Cotinus coggygria, Platanus ×acerifolia, P. orientalis, Quercus faginea, Q. petraea, Q. robur.
