. Foundations of Botany. Botany. 258 FOUNDATIONS OF BOTANY Wet a bit of the mould, first with alcohol, then with water. Examine in water with the half-inch objective, and sketch a little of the mycelium, some of the spore-cases, and the thread-like stalks on which they are borne. Are these stalks and the mycelium filaments solid or tubular ? Are they one-celled or several-celled ? Mount some of the mature spore-cases in water, examine them with the highest obtainable power, and sketch the escaping Fig. 189. — Unicellular Mycelium of a Mould (Mucor Mucedo), sprung from a Single Spore.

(Considerably magnified.) Sow some of these spores on the surface of " hay-tea," made by boiling a handful of hay in just water enough to cover it and then straining through cloth or filtering through a paper filter. After from three to six hours examine a drop from the surface of the liquid with a medium power of the microscope (half-inch objective) to see how the development of hyphae from the spores begins.
