GENERA AND SPECIES OF MUSHROOMS 



moist in wet weather; green or dingy green, fading with age or 

 on drying; flesh whitish; odor pleasant, Hke that of anise; 

 size, I >^ to 3 inches in diameter. 



Gills thin; attached to the stem; (adnate) or extending 

 slightly down the stem (decurrent) white, pallid, or grayish- 

 green (glaucous). 



Stem cylindrical or slightly thicker at base; stuffed or hol- 

 low elastic; smooth; whitish or greenish; thin, Ve to y^ inches 

 in diameter. 



Spores white; 6 to 8 microns by 4 to 5 microns in diameter. 



The genus Clitopilus 



The species of this pink-spored genus have fleshy stems and 

 gills extending down them (decurrent). Mushrooms with 

 similar gills and stems but white spores, belong to the genus 

 Clitocybe. The pink-gilled species of this genus, Clitopilus, 

 may be distinguished from the pink-gilled common mushroom 

 by the fact that they retain their pink hue when old, not turn- 

 ing dark brown and finally black. Besides in the common 

 mushroom and its family, the gills are free from the stem while 

 in the genus Clitopilus they are attached, as mentioned above. 

 Many species of pink-spored mushrooms, both in this genus 

 and in others have white or whitish gills when they are young, 

 turning to a pinkish hue with advancing age. This is due to 

 the ripening of the pink spores upon their surfaces.
