saprobes:
|
absorb nutrients from nonliving sources

absorb nutrients from living sources to the detriment of the host
|
|
mutualists
|
both fungi and host benefit from the relationships (mycorrhizal association)

|
|
ascomycota
|
|
|
crustose lichen- flat and adhere tightly to the surface of rocks or tree
