Cheryl, if it is not a lot of trouble, it would be nice to see pictures.
I always get strange things growing. Dog vomit fungus, stink horn, and I never know if it is OK to leave or remove. Maybe a person experienced in mold and fungus or soil will be able to tell what it was and what you do about it. I use some of these questions for future reference because they are helpful. I may not have encountered the problem in the past, but I might tomorrow.
May you be blessed for the remainder of the year!
