You will look at three types of ascocarps in this part of the exercise: a cleistothecium (closed and spherical) a perithecium (vase-shaped with a small pore at one end) or open and an apothecium (cup-shaped). The asci usually develop as a layer inside the ascocarp. Examine prepared slides of Erysiphe (powdery mildew, a plant parasite). When you look at this slide, remember that most of the body of any fungus is located inside something; in this case, the plant stem, which occupies most of the slide. The ascocarps are located on the outer edge of the plant stem so that spores can be dispersed by air currents. Locate the ascocarps containing asci and ascospores . This ascocarp is a cleistothecium . Why? Sketch a typical cleistothecium and its contents in the space to the right....
