Description

  • The cap is 0.8— 2(2.5) cm broad and is obtusely conic, becoming broadly campanulate to broadly conic, often with an acute umbo. It is tawny dark brown when moist, fading to pale yellowish brown or grayish brown. It is even to striatulate when moist, smooth, hygrophanous, and viscid when moist from a thin gelatinous pellicle that is barely separable, if at all. It sometimes has a grayish-green tinge along the margin. It fades to pale buff.
  • The gills are adnate to adnexed, close to subdistant, narrow to moderately broad, and dull grayish brown to cinnamon brown at first then smoky brown at maturity, edges remaining whitish.
  • The spores are dark purplish brown, (6.6)8.5 — 9.5(11) x (3.8)4 — 5.5(6) µm from 4-spored basidia, which are sometimes 2-spored.
  • The stipe is 2— 8 cm long by 1— 3 mm thick, equal to slightly enlarged at the base, tubular, and somewhat flexuous. It is pallid to brownish beneath a silky fibrillose covering. It becomes darker towards the base, partial veil poorly developed, cortinate, thin to obscure, and soon absent. It is slightly bluish-green at base.
  • It has a farinaceous taste and odor.
  • Microscopic features: Pleurocystidia are absent. The cheilocystidia are 24 — 34(40) x 4.4 — 6.6(8.8) µm, fusoid ventricose to lageniform, with a long flexuous neck, and are1.6 — 2.2 µm thick.

Famous quotes containing the word description:

    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)

    As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.
    Henry David Thoreau (1817–1862)

    I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.
    Thomas Jefferson (1743–1826)
