g() Twenty-third Report on the State Cabinet. 



On rotten logs and stumps in woods and open places. 

 May-October. Very common. 



5Q. Agaricus Fibula Bull. 



Pileus tliin, convex, umbilicate, smooth, yellow or pale 

 orange, striatulate ; lamellse narrow, arcuate, long decurrent, 

 whitish ; stipe elongated, slender, smooth, hollow, concolorous. 



Height l'-2', breadth of pileus l"-3". 



On mossy ground in fields and groves. June-October. 

 Common. 



The pileus becomes brighter colored in drying. 



Subgenus — Pleurotus. 



Stem eccentric, lateral or wanting. Mostly growing on 

 wood. — Berk. Outl. 



In this subgenus the pileus is either destitute of a stem or has 

 it attached to the margin or to some point outside of the center. 

 The texture is more firm, the plant of slower growth and longer 

 duration than in any of the preceding subgenera. 



Synopsis of the Species. 



Stipe distinct, eccentric 58. 



Stipe very short, lateral 59. 



58. Agaeicus sulfureoides n. sjy. 



Pileus rather thin, fleshy, convex, umbonate, subsquamu- 

 lose or smooth, sulphur- yellow ; lamellse moderately close, 

 rather broad, roundevl or slightly emarginate at the inner 

 extremity, easily separating from the stipe, pale yellow ; stipe 

 firm, equal, slightly fibrillose, stuffed or hollow, generally 

 curved and eccentric, rarely central, a little mealy-tomentose 

 at the top. 



Height l'-].5', breadth of pileus l'-2', stipe 2"-3" thick. 



On old logs in woods. Catskill Mountains. October. 



The pileus becomes paler in drying. The minute scales are 

 brown, but often wanting. It resembles A. suJfureus, but 

 from its firm texture and eccentric stipe it must be placed 

 with the Pleuroti.

 tomentose, slightly viscid when young or moist, the margin
