The mycelium is, therefore, the vegetative part of the Mush- room while the stalked jiileus above the surface is the fructification. The mycelium is developed directly from the siiore, but so far there have not been discovered any indications of the interaction of sperm-cells and germ-cells Mich as characterize the Bryophytes and Pteridophytes. You will note the entire absence of green colourin--matter. The Mushrooms iiroduco no chlorophyll, and, conse- 'lueiitly, are incapable of assimilation. They are always found growing upon decaying organic matter, as the leaf- soil of forests and meadows, etc. The Mushrooms are representatives of a large class of plants called Fungi, all the members of which are destitute of chlorophyll. The cells of which they are made up are generally in rows .so as to form long threads which are known as liyp/ice, and these may be either loosely inter- woven, as in ordinary Moulds, or firmly compacted to- gether, as in the Mushroom. As just mentioned, Mushrooms are saprophytic in their habits; but there are also Fungi which are parasitic, such as Rust and Smut. To the Fungi belong such organisms as the \east-plan
