MSU Diagnostic services can test for fungi problems. Usually the plant would be tested, but you might want to contact the lab for details and if they make recommendations on how to treat the problem in the soil. The website for the Diagnostic Lab is: https://pestid.msu.edu/ The web page has the location and contact information for the lab along with forms, services and fees and how to submit samples.
