oreades (Bolt, ex Fr.) Fr. when grown in manure produces large amounts 

 of edible fungi much larger than the wild form. (Fig. 167.) 



Among the edible wild species are various kinds of Lepiota, e.g., L. 

 naucina (Fr.) Quel., L. procera (Scop, ex Fr.) Quel. {Leucocoprinus pro- 

 cerus (Scop, ex Fr.) Pat.). It must be noted that some species of this genus 

 are poisonous. Most of the larger species of Agaricus (PsaUiota of some 

 authors) are edible, e.g., A. campestris L. ex Fr., A. rodmani Pk., A. 

 arvensis Schaeff. ex Fr., etc. Pluteus cervinus (Schaeff. ex Fr.) Qu61., 

 Coprinus comatus Fr., C. micaceus Fr., C. atramentarius Fr. (but see 

 under poisonous species below), Marasmius oreades, Ladarius volemus 

 Fr., L. deliciosus (L.) Fr., Pleurotus ostreatus (Jacq. ex Fr.) Quel., 

 P. ulmarius (Bull, ex Fr.) Qu61., CollyUa radicata (Rehl.) Berk., and 

 various other species of CoUyhia, Tricholoma personatum (Fr.) Qu^L, 

 Armillariella mellea, and many others are edible. Of the genus Amanita, 

 A. rubcscens (Pers. ex Fr.) Fr. and A. caesarea Schaeff. ex Fr. are highly 

 prized, but see note concerning this genus among the poisonous species 

 below. Aside from the hundreds of edible species of mushrooms there are 

 many that are poisonous, some mildly so, some dangerously. Besides these 

 edible and poisonous sorts the larger number of species are too small or 

 tough or shmy in consistency, or of disagreeable odor or taste even though
