Note 17 — THE RANGE OF FUNGUS GROWTHS.

Few minute objects are more beautiful than certain of these mucedinous fungi fungorum. A common one besets the back of some of the Russulæ in decay, spreading over it, especially if the weather be moist, like thin flocks of light wool, presenting on the second day a bluish tint on the surface. Under a powerful magnifier, myriads of little glasslike stalks are brought into view, which bifurcate again and again, each ultimate twig ending in a semilucent head, or button, at first blue, and afterwards black; which, when it comes to burst, scatters the spores, which are then (under the microscope) seen adhering to the sides of the delicate filamentary stalks like so many minute limpets.
