Agaricacese 



(Plate XXXII.) 



MYCE'NA Fr. 



Gr, a fungus. 



Mycena. PileilS regular, rarely depressed in the center, thin, usually streaked 



with longitudinal lines, at first con- 

 ico-cylindrical, margin at the first 

 straight, closely embracing the stem 

 which is attenuated upward. Stem 

 hollow, slender, cartilaginous. Gills 

 adnate or adnexed, sometimes with a 

 small tooth, never decurrent. SpOl'GS 

 white. 



Generally small and slender, grow- 

 ing on branches, twigs, heaps of 

 leaves, sometimes on the ground, 

 some minute species on single dead 

 leaves. Long, rooting stems are not 

 uncommon. Clitocybe and Ompha- 

 lia are separated by their decurrent 

 gills and in Collybia the margin is 

 at first incurved. 



In this genus the species of the various sections are not always dis- 

 tinguished by single sharply defined characteristics, so that it will some- 

 times be necessary to pay attention to all the features. Species with a 

 thread-like stem are found in other sections than Filipedes and some of 

 the Lactipedes are slippery when moist, but not truly viscous.
