Our mass of conferva turns out to contain one of the most elegant species.
But if the conferva or parasitic fungus exceeds its allies in the above respects, it will then be dominant within its own class.
In the stomach of C. balnaris I found a considerable quantity of a conferva, too much, I think, to have got in accidentally.
The consequence has been an excessive growth of a conferva which is indigenous to these lakes and confined to them.
In the hottest water of the hot springs I collected three species of conferva.
Polyps may be obtained at all times of the year by bringing home duckweed, conferva, and other water-plants from the ponds.
