These are leaves from a frost proof gardenia. I found this desciption of what I think it is. Does anybody else have an opinion?

Leaf Spot (fungi--Cercospora spp., Phyllosticta spp.)
These fungi cause spots of various sizes on leaves throughout the year. Spots may be small, dark-brown necrotic areas surrounded by a yellow halo. In severe cases, premature leaf drop may occur. Control is obtained by spraying with a folia fungicide at regular intervals.

Thanks for any help.
