Microsphaera hypophylla Nevod. 1952

Description

Type: Powdery Mildews; Description: Mycelium superficial, evanescent, white or grey white, hyphae 5–6 μm wide; mainly on the lower surfaces of leaves. Appressoria multi-lobed. Ascomata not seen in New Zealand. Conidiophores 90–100 × 7–10 μm, foot cell flexuous. Conidia produced singly, cylindrical, 0-septate, 35–45 × 12–18 μm, smooth, hyaline.

Distribution

Distribution: Auckland.; 1st Record: Boesewinkel (1980).

Notes

Pathogenicity

Significance: Uncommon and appears to cause little damage. This species can be distinguished from the more common Microsphaera alphitoides by its evanescent mycelium, longer conidiophores, flexuous foot cell, and the shape of the conidia.; Host(s): Quercus petraea.
