Marian, do you know how to distinguish sugar from Norway maples? In Wolfville the sugar maples have another fungus, ANTHRACNOSE, which does not make spots on the leaves, but just dries up the leaf edges which get brown and crispy. For Norway vs. sugar maple, there are differences in leaf shape, in how much lighter coloured the back of the leaf is, and in the size and angle of the pairs of fruits/seeds. Find a tree book somewhere. Gary Saunders' Trees of Nova Scotia is cheap and good and for sale at the N.S. Museum of Nat. Hist. -- perhaps in libraries? -- and other books should be helpful as well. I will try to embellish this note about distinguishing marks later. And thanks to all of you who have responded to my initial inquiry about the distribution of tar spot fungus on maples.

There were fewer spots this year than previously. I saw several maples at Amherst Point Bird Sanctuary last month with these similar spots. I also saw them on maples in the Rideau Lakes region on Ontario (Portland on Big Rideau Lake) when I was there a couple of weeks ago.

For a nice photo, go to NovaNewsNow.com Web-site, choose the Advertiser icon, then search "tar spots" for the article and photo. Cheers from Jim in Wolfville ---------------
