The morels.—These are large fleshy fungi with a stout stalk bearing a large head which is covered with numerous shallow depressions separated by ridges. The entire surface of the head is covered with the asci intermingled with numerous sterile hyphae (paraphyses). The morels (Morchella) appear in damp places in early spring and are prized as edible fungi. They are sometimes called mushrooms, but do not belong to the true mushroom group. 431. The yeast fungi.—The yeast fungi, or sprouting fungi, as they are often called, are by some classed among the sac fungi as degenerate forms. The yeast plant is remarkable for its activity in producing fermentation especially of solutions containing sugar (see paragraph 192 for fermentation by yeast), giving off COo and forming alcohol; one yeast {Saccliaromyces cerivisece) is used both in bread-rising and in brewing beer. The yeasts usually consist of single cells, oval or elliptical in form, and in this con- dition they are single-celled plants. They multiply by a process of budding or sprouting. Near each end of a cell a small bud appears which has only a frail connection with the parent yeast cell. This bud increases in size, and soon separates, forming a new yeast plant. Sometimes these buds remain connected for a time, form- ing small colonies, which soon separate into the separate cells if.
