You may want to look at a shelf fungus under magnification to answer this question. List them below indicating in what form you found them. Deuteromycetes are NOT a monphyletic group. Although they look like individual organisms, lichens are actually a symbiotic association between an autotroph and a fungus. The autotroph is either a green alga or a cyanobacterium, and the fungus is most often an ascomycete.
Lichens are extremely hardy and can survive severe water stress.
Examine the microscope display of the sectioned lichen. Be sure you can see the fungal hyphae and algal symbionts. In a culture dish of Polytrichum , look for a stem that has a sporophyte growing out of it. Bring one of these stems back to your desk, and place it on a slide in a drop of water under a dissecting microscope. Again, dissect away the outer leaves until you see the base of the young sporophyte growing out of the stem tissue.
