Ammonia fungi are fungi that develop fruit bodies exclusively or relatively abundantly on soil that has had ammonia or other nitrogen-containing materials added.
The nitrogen materials react as bases by themselves, or after decomposition.
[1] The addition of ammonia or urea causes numerous chemical and biological changes, for examples, the pH of soil litter is increased to 8–10; the high alkaline conditions interrupts the process of nutrient recycling.
[2] The mechanisms of colonization, establishment, and occurrence of fruiting bodies of ammonia fungi has been researched in the field and the laboratory.
