Unfortunately Piktochart, which is where I was hosting my graphic, deleted my account. I may have the info in a spreadsheet somewhere, if I have time someday I will see if I can get the info on here somehow. In the meantime you can just do the same research I did to create the spreadsheet: simply find out what sort of ecosystem niche your desired plant NATURALLY grows in. If it is a vegetable you need to find the original, wild ancestor of that vegetable (for the cabbage family look for “Sea Kale”, for example) and find out where THAT grows. The general categories, in order of more-fungi to less-fungi would be: inside a dense forest, on the edges of a forest or in an open forest, in a long-term grassland, in a recently disturbed grassland, on newly disturbed ground (or any other area with poorly developed soil like rocky cliffs, etc.).
