Nectria Canker (Nectria galligena) 2006-4-15 - Parvin State Park, NJ

More information about this Canker can be found in the Nature Album under Fungi/Mushrooms.

Nectria Canker is often called Target Canker. Nectria has other forms of Canker, but this particular disease, with this very identifiable structure, is caused by a fungus, Nectria galligena. I look forward to the opportunity to go back to Parvin and get better pictures of this Canker, properly ID the trees it's on (I think Sassafras), and maybe, just maybe, get a picture of the tiny fungus itself.
