Erysiphe cichoracearum DC. 1805

Type: Powdery Mildews; Description: Mycelium well developed, superficial, moderately dense to dense, white, hyphae 4–8 μm wide; on leaves and twigs. Appressoria nipple-shaped, smooth or slightly wrinkled, rarely lobed. Ascomata (found in New Zealand only on Aster) cleistothecial, scattered or gregarious, superficial, globose, dark brown, 0.85–0.16 mm in diameter, with numerous, rarely branched, basally inserted appendages 0.5–4 times as long as the cleistothecial diameter, hyaline at first, later becoming pale to deep brown throughout or in the basal half. Asci 6–25 per ascoma, oval to subglobose, stalked, 50–80 × 25–45 μm. Ascospores 2–3 per ascus, oval, 0-septate, 15 × 25 μm, smooth, hyaline. Conidiophores 75–200 × 9–15 μm, foot cell straight or with curved basal part. Conidia produced in long chains, cylindrical at first, becoming barrel-shaped as they mature, 0-septate, 25–42 × 14–22 μm, length/width ratio ≈ 2, smooth, hyaline.
Distribution: Northland, Auckland, Coromandel, Wanganui, Wellington, Mid Canterbury.; 1st Record: Brien & Dingley (1955).
Notes: This species has previously been confused with the polyphagous species Erysiphe orontii (p. 220); the name E. cichoracearum is now restricted to the pathogen of asteraceous hosts.
Significance: Of no significance, except on herbaceous Asteraceae.; Host(s): Brachyglottis repanda, Olearia rani.
