“Leaves develop lesions that are roughly circular, raised and purple to reddish-brown. The alga produces microscopic, rust-colored, spore-like bodies on the surface of the leaf spots, giving them a reddish tinge. The “spores” are dispersed by wind or rain and spread from leaves to branches and fruit.Most algal spots develop on the upper leaf surface. Older infections become greenish-gray and look like lichen. Cephaleuros usually does not harm the plant.”
