Does a Toadstool Grow on the Side of a Tree?
Toadstools are fungi and closely related to common mushrooms. There are edible toadstools and poisonous ones. They may grow in turf or on dead and rotting trees. Toadstools are the fruit of mycelium, which grow under the surface of the soil or in the tree wood. Mycelium may be present for many years and then "bloom" when the conditions are conducive. Warm, mild temperatures and moisture are the key elements mycelium need to produce fruit. Does this Spark an idea?

Description
-
There is no scientific distinction between mushrooms and toadstools. The classic image depicts toadstools as having broad caps and slender stems with prominent gills on the underside of the cap. They are often shown in bright colors with spots or streaks. Toadstools can also be a dull brown, beige or white and can be shelf shaped, flat, round and stemless and many other forms. The toadstool may have gills or it may have pores as is the case in the round, stemless varieties.
Location
-
Fungi will grow where they have plenty of organic material to fuel their activities. Many toadstools will grow out of trees. They are usually not damaging and some are actually beneficial. An exception to this is the honey fungus, or armarilla, which can kill a tree. Most tree fungi feed off the detritus that collects on the tree and do not actually eat the wood. The fungi may also grow in the soil and are often found in the lawn where high levels of nitrogen and moist conditions fuel the production of the fruiting bodies.

Toxicity and Control
-
Toadstools may be eaten if you know what you are picking. Not all toadstools are safe to eat and some are extremely poisonous. Just because something tastes good doesn't mean it is safe and the converse is true of those fungi that taste awful. There is little you can do to control fungal blooms. The toadstool bodies may be manually removed but every time conditions are mild and moist, the mycelium will bloom again. Fortunately, most toadstools are not dangerous or harmful to trees or lawns and require no action.
Varieties of Toadstool
-
Two main types of toadstool exist. Saprophytes are organisms that feed on dead and decaying organic matter. They may be found on dead animals or plants and are beneficial for breaking down these types of matter. The decomposition releases nutrients into the soil. Mycorrhizae are strings of fungal matter that form a symbiotic relationship with the roots of plants. The fungus gets some of its nutrients from the plant and in turn enhances the ability of the plant to uptake food and moisture.
