52 AGARICINI. 



P. Serotinus. Fr. Late Agaric. 



This late Agaric you can find on old logs in dense woods. 

 It rarely makes its appearance before late in September, and 

 good specimens can be found in December. It is a beautiful 

 species. The stem part is adorned with dark-brown spots on a 

 yellow base. Peck considered it a separate species and named 

 it P. serotinoides, Pk. 



Agaricus serotinoides. Pk. 



Pileus, fleshy, one to three inches broad, compact, convex 

 or nearly plane, viscid when 3'oung and moist, dimidiate reni- 

 form or suborbicular, solitary or caespitose and imbricated, 

 variously colored, dingy-yellow, reddish-brown, greenish- 

 brown or olivaceous, the margin at first involute. 



Gills, close, determinate, whitish or yellowish. 



Stem, very short, lateral, thick, yellowish beneath and 

 minutely toraentose or squamulose with blackish points. 



Spores, minute, elliptical, .0002 inch long, .0001 inch 

 broad. — Peck' s Reports. 



The late agaric is truly a late fungus, not appearing before frost sets in. 

 It is a beautiful specimen. The stipe is the beautiful part of it — of a 

 beautiful golden yellow, speckled with darker dots. You will meet with 

 it growing on old logs from September on to January. I have found 

 well-preserved specimens in the latter part of December. 



Found in Albright's jungle, near mill race. 



P. niger. Schw. The Black Agaric. 



This is the smallest of the Pleurotus and is resupinate — that 

 is, with the gills facing the light. You will meet with it all 

 summer on decayed, moist limbs, like so many black shirt 

 buttons. 



Jungle, Trexlertown.
