Sawadaea is a genus of fungi in the family Erysiphaceae (powdery mildews). It contains twelve species.[1]
Description
The fungus forms white patches of mycelium on the leaves of its host.[2] Some Sawadaea species have a 'spring' and 'autumn' phase. In spring, the mycelium appears on the upperside of leaves. In autumn, it can be found on the undersides.
Taxonomy
The genus was initially circumscribed by Kingo Miyabe in 1914. The genus name of Sawadaea is in honour of Kaneyoshi (Kenkichi) Sawada (1888–1950), who was a Japanese botanist and mycologist. He worked at the College of Agriculture in the National Taiwan University.[3]
