[Daily article] December 16: Geastrum quadrifidum Published On

Geastrum quadrifidum, commonly known as the rayed earthstar, is an
inedible species of mushroom belonging to the genus Geastrum, the
earthstar fungi. First described by Christian Hendrik Persoon in 1794,
it is a cosmopolitan but uncommon species found in Europe, the Americas,
Africa, Asia, and Australasia. The fungus feeds off decomposing organic
matter in the litter and soil of coniferous forests. The small, grayish-
brown fruit bodies are enclosed by a skin, or peridium, made up of four
layers of tissue. The outer layer splits to form star-like rays and
expose a spore case, inside of which is the gleba—fertile spore-
producing tissue. The spore case, set on a short, slender stalk, has a
well-defined narrow pore at the top through which mature spores escape.
The mushroom's outer skin is purplish-brown, with four or five cream or
yellowish-brown rays whose tips are stuck in the substrate. This species
is one of several earthstars whose rays arch downward as they mature,
lifting the spore sac upward and allowing it to catch air currents that
disseminate the spores.

  It seems to me very important to continue to distinguish between
two evils. It may be necessary temporarily to accept a lesser evil, but
one must never label a necessary evil as good.
