AOARICINI.

naceous^ ovato-campanulate^ furfuraceous, then naked, sulcato- 

 plicate, changing colour ; stem somewhat flcxuous, brittle, 

 furfuraceous, then smooth ; gills adnate, broadly linear, dirty- 

 white, then black. — Sotv. t. 1G6. 



About the trunks of trees, and on the ground. Forming 

 lai'ge tufts. Extremely common. Pileus a few lines only 

 across. Approaching very near to Cojwiiius. A. memhra- 

 naccus, Bolt., is too doubtful as to its affinities to admit of 

 its being registered. 



2. COPRINUS, Fr. 



Gills membranaceous, deliquescent. Spores black. 

 1. Pileus not jiUcato-suJcaie. 



1. C. comatus, Fr. ; pileus rather fleshy, cylindrical, obtuse, 

 then expanded, soon torn up into broad, scattered scales ; 

 stem hollow, fibrillose, stuffed Avith a cottony web ; bulb solid, 

 rooting; ring moveable; gills free, linear, white, then tinged 

 with red. — Grev. t. 119. 



Sides of roads, pastures, etc. Common. Extremely variable 

 in size. Esculent when young. I believe that Bolt. t. 142 

 is a mere variety. I have found C. comatus at Abergele equally 

 dwarf, and with a precisely similar volvate ring. 



2. C. sterquilinus, Fr. ; pileus membranaceous, conical, 

 expanded, sulcate, at first villous; disc rather fleshy, rough 

 with scales ; stem attenuated, fibrillose, solid, rootless, having 

 a ring; gills free, ventricose, purplish. — Mich. t. 83. /. 3. 



On dung. Bare. King's Cliffe. About 1 \ inch across. 



3. C. atramentarius, Fr. ; pileus rather fleshy, OAate, at 

 first irregular, spotted above with innate scales; stem firm, 

 hollow, zoned within ; ring abrupt, fugacious ; gills free, ven- 

 tricose, white, then purplish-black. (Plate 12, fig. 1.)
