AGARICUS. 



Mycena. Subgenits VII. MYCENA (/ivxrjs, a fungus). Fr. Syst. Myc. i. 



p. 140. Stem fistulose, cartilaginous. Pileus somewhat mem- 



branaceous, more or less striate, at the 

 first conico- or parabolico-cylindrical 

 by reason of the margin being at the 

 first straight, and either clasping the 

 stem which is attenuated upwards, or 

 pressed close and parallel to it. Gills 

 not decurrent (or only uncinate by a 

 small tooth). Epiphytal or rooted, 

 slender, somewhat campanulate, scarce- 

 ly umbilicate. Fr. Hyvi. Eur. p. 129. 

 Distinguished from the minute Col- 

 lybiae by the margin of the pileus 

 never being involute, but straight and 

 pressed parallel to the stem, and from 

 the Mycenarian Omphalias by the pile- 

 us being commonly umbonate. Some 

 ^^ _ last far into autumn or winter; others 



are very fugacious. Most of them are inodorous, but some have 



an alkaline smell or an oclour of radish. None of them are 



edible.

VIII. Agaricits (iWycetia) poly- 

 grammus. One-fourth natural 

 size. 



I. Calodontes (xaXd?, beautiful; 6Sov?, a tooth). Stem juiceless, base not 

 dilated into a disc. Edge of gills darker, denticulate (more or less, Monogr.}, 

 a mark by which they are distinguished from all others, except A. sanguin- 

 olentus, which has a milky stem. By far the most distinguished species. 



II. Adonidere (from Adonis, denoting beauty). Stem juiceless, base not 

 dilated into a disc. Gills of one colour, and not of a different colour at the 

 edge, nor changing colour. Colotir pure, bright, not becoming fuscous or cin- 

 ereous. Growing singly on the ground (except A. Iris) and requiring to be 

 carefully distinguished from white and coloured varieties of Rigipedes, the 

 gills of which turn pale from white. 



III. Rigipedes (rigid-stemmed). Stem firm, rigid, somewhat tough, juice- 

 less, somewhat strigose and rooted at the base. Gills changing colour, white 

 then grey or reddish, commonly at length connected by veins. Pileus not 

 hygrophanous. Tough, persistent, inodorous, normally growing on wood and 

 very ccespitose, but individuals occur growing singly and on the ground. 



IV. Fragilipedes (fragile-stemmed). Stem fragile, dry, juiceless, fibrillose 

 at the base, scarcely rooting, but not dilated or inserted. Pileus hygrophan- 

 ous. Gills changing colour, at length somewhat connected by veins. Thin- 

 ner, fragile, often soft, commonly smelling, normally growing singly and on the 

 ground, a few (strong-smelling ones) growing on wood and ccsspitose. 



V. Filipedes (thread-stemmed). Stem filiform, scarcely a line thick (and 

 not more), flaccid, somewhat tough, rooting, dry, juiceless, commonly very 

 long in proportion to the pileus. Gills changing colour, somewhat lighter- 

 coloured at the edge, distinct. Very slender, tense and straight, growing on the
