Other Fungi: groups of microfungi

As can be seen in the lists below, there is a vast array of fungi that are microscopic. The majority of plants harbor arbuscular mycorrhizal fungi, Glomeromycota, in their roots but it requires microscopic techniques to see them. They generally don't produce fruitbodies, just large spores in the soil. Besides bread molds in your kitchen you may find Spinellus fusiger, a zygomycete mold on the mushroom Mycena haematopus. One cytrid you may find in the woods is Synchytrium decipiens, a bright orange "false rust" parasite on the plant called American hogpeanut (Amphicarpaea bracteata).

The classification shown above is from McLaughlin and Spatafora (2014).
