In picture "K" you can see bacteria that are capable of photosynthesis. They are also know as blue green-algae or blue-green bacteria. What is their real name?
In the picture above is a type of fungus reproduction. What type of reproduction is it?
In the picture above is a fungal growth that typically takes the form of a domed cap on a stalk, often with gills on the underside of the cap.
In the picture above is the spore-bearing fruiting body of a fungus, typically in the form of a rounded cap on a stalk. These are usually inedible or poisonous.
