Entolomataceae - Description

Description

The very large family Entolomataceae has a cosmopolitan distribution, and species are common in both temperate and tropical climates. Although the shape of the fruiting body and many microscopic characteristics are very diverse, it forms a well-defined group due to the distinctive spores:

  • the spore print is pink (or brownish or greyish pink) and
  • the spores are ornamented with bumps or ridges, or have a sharp-pointed polygonal cross-section.

The spore ornamentation is formed by a unique form of spore wall thickening, which is called the epicorium.

One notable member is the edible Miller mushroom (Clitopilus prunulus). Many members of the Entolomataceae are poisonous and most are very obscure and difficult to identify properly. Examples are the poisonous type species of Entoloma, Entoloma sinuatum, found in Europe and North America, and E. rhodopolium in Europe and Japan.

Famous quotes containing the word description:

    A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else.
    John Locke (1632–1704)

    The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St Paul’s, like the editions of Balbec and Palmyra.
    Horace Walpole (1717–1797)

    God damnit, why must all those journalists be such sticklers for detail? Why, they’d hold you to an accurate description of the first time you ever made love, expecting you to remember the color of the room and the shape of the windows.
    Lyndon Baines Johnson (1908–1973)
