Fairy ring of mushrooms in lawn. ? amanitas?

Asked September 7, 2017, 12:53 PM EDT

I have an expanding ring of mushrooms in my lawn that has been there for years. Until this year it has not been a problem. I have a 9 month old puppy that is quite interested in the mushrooms. I am very concerned they may be amanitas. How can I get the mushrooms positively identified? I have researched and asked amateur "mushroomers' but have to be sure. There are too many look-a-likes. The gills in the photo look pink but they are actually a creamy white on all the mushrooms I have seen so far. I have been digging them out and have not let any mature this year.

Correctly identifying mushrooms involves getting a spore print as well as looking at other physical characteristics of the mushroom. MSU Extension has a booklet entitled "Don't Pick Poison" which can help in identifying mushrooms at: https://www.oakgov.com/msu/Documents/publications/e2777_poison_mushrooms.pdf

The MSU Plant Lab does not do mushroom identification. For more help you can try contacting the Michigan Mushroom Hunters Club at: https://www.michiganmushroomhunters.org/ or the North American Mycological Association at: http://www.namyco.org/

You might also try contacting a local college or university to see if they have a mycologist on staff who could help.

A good resource to help with mushroom identification is "Simon and Schuster's Guide to Mushrooms" from their Nature Guide Series.
