AGARICUS. 



VIII. Agaricus i^Mycena) poly- 

 gram7iuis. One-fourth natural 

 size. 



Mycena. Subge7ius VII. MYCENA {ixvkt]s, a fungus). Fr. Syst. Myc. i. 



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

 branaceous, more or less striate, at the 

 first conico- or parabolico-cylindrical 

 by reaso7i of the margin being at the 

 fi?'st straight, and either clasping the 

 stem which is attenuated upwards, or 

 pressed close a?id parallel to it. Gills 

 not decurrent (or only uncinate by a 

 small tooth). Epiphytal or rooted, 

 slender, somewhat campanulate^ scarce- 

 ly umbilicate. Fr. Hym. Eur. p. 129. 

 Distinguished from the minute Col- 

 lybias by the margin of the pileus 

 never being involute, but straight and 

 pressed parallel to the stem, and from 

 the Mycenarian Omphaliae 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 odour of radish. None of them are 



edible. 



I. Calodontes {k.oX6<;, beautiful; 65ovs, a tooth). Stem juiceless, base not 

 dilated into a disc. Edge of gills da7-ker, denticiilate (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 distmguished species. 



II. Adonideas (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. Colour pure, bright, not beco7?ii?ig 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, persistcftt, i?2odo?'ous, noi'vially growing on -wood and 

 very ccespitose, but individt(als occzir growing singly afid o?i the ground. 



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

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

 ous. QiW\% changing colour, at length somewhat connected by veins. Thin- 

 ner, fragile, often soft, commonly synelling, 7wrmally growing singly a7id on the 

 grou7id, a few (strong-smelling ones) g7-07uing on wood a7id ccespitose. 



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 changi7ig colour, somewhat lighter- 

 coloured at the edge, disti7ict. Very slender, tense a7id st7-aight, g7-owing o/i the
