You could very well have a variant blight strain there, but there is another possibility.  Magness is commonly 
referred to as "blight resistant".  BUT, it is a funny cultivar.  It is blight resistant only if the blight enters via 
twigs.  Magness has been shown to be blight-susceptible if inoculum comes in contact with the trunk.  It was 
first noticed after a hailstorm at Beltsville injured some Magness trees allowing blight to enter through older 
wood.
