ResumoSUMMARY1. The coprophilous Bird's Nest Fungus Cyathus stercoreus has been induced to fruit in laboratory culture.2. From a long series of haploid mycelia, all derived from spores of a single peridiole of one wild type specimen, a large number of diploid strains have been obtained that differ from one another in color, texture, growth rate and other characters according to the nature of the haploids from which they were produced.3. Different strains of diploid mycelium fruiting in culture have produced fruit bodies of several different types, some so unlike the parental wild type as to bear little superficial resemblance to C. stercoreus.4. The most distinctive types of fruit bodies illustrated and described are: a small deep brown abortive form; a tall slender, very pale form with a reddish brown base; a broad, flat, saucer-shaped form with sulcate cup; a minute or dwarf form; and a greyish form provided with a bright rust colored cap when young.5. The characters of the species that have appeared least variable in culture are the hairy nature of the cup, the color of the peridioles and their lack of a tunica or outer covering, and the average size of mature basidiospores.6. The possible connection between these culture types of fruit bodies and the various forms of C. stercoreus that have been described from nature is discussed.
