Mushrooms in my yard
Thank you for reaching out to Extension Services, unfortunately, we don't have any experts in our system that can ID mushrooms - our Master Gardener programs also are not able to ID mushrooms. We generally recommend that you contact a local mycological society. In your area, your statewide Mycological Society has resources for identification, you can find them here, scroll down to Guidebooks and Eating Wild Mushrooms https://www.wildmushrooms.org/
Like Extension, The Oregon Mycological Society doesn’t identify mushrooms for the public via email or its website. (It’s too easy to get wrong from just photos, and there are liability issues.) You may be able to get help by posting photos on web sites like:
Facebook Pacific Northwest Mushroom Identification Forum
(Neither OMS nor Extension are associated with these sites. The identifications they offer may be inaccurate.)
Sometimes you can eliminate mushrooms growing from organic matter or hasten decomposition of organic matter by applying nitrogen fertilizer at a rate of 1 pound of actual nitrogen per 1,000 square feet of lawn. The nitrogen should be readily available and not a slow-release or water-insoluble formulation. Examples include 5 pounds of ammonium sulfate (21-0-0) or special lawn fertilizers such as 6 pounds of 16-6-8 or 4 pounds of 27-3-4 per 1,000 square feet of lawn. Fertilization hastens decomposition of organic matter." http://ipm.ucanr.edu/PMG/PESTNOTES/pn74100.html
I hope that suggestion helps you decide if you need to remove these fungi and if so what steps to take. Please reach out if we can help you further.
