Exobasidium vexans Massee - (blister blight of tea)
This fungus infects tea plants (Camellia sinensis) in Asia, causing the blister blight disease. It is of quarantine concern in other tea-growing regions like East Africa. Outbreaks can result in up to 40% yield losses.
Infections start as reddish, yellowish or green leaf spots. These enlarge, become whitish, hollow and eventually burst, releasing elliptical basidiospores which are around 20 µm long and 5 µm wide. These spores disperse by wind and initiate new infections.
