114 . THE AGARICACEAE OP MICHIGAN 



the brown color. STEM 6-7 cm. long, 1.5-2.5 cm. thick, stout, firm, 

 solid, equal, dry, more or less tinged concolor and subvelvety. 

 SPORES globose, echinulate, 9-12 micr., white. MILK white, un- 

 changing, mild, copious. ODOR slight. 



Gregarious or solitary. On the ground in frondose woods or open 

 places. Detroit, Ann Arbor. August- September. Infrequent. 



Closely related to the preceding, of which it might be considered 

 a variety. The rugose or corrugated pileus and the abundance of 

 brown spicules on the gills are the main distinguishing characters.

 current, distant, narrow, often intervenose, whitish to cream-yellow- 

 ish. STEM 2-4 cm. long, short, S-16 mm. thick, equal or tapering 

 downward, solid, glabrous or pruinose, concolor. SPORES globose 

 to broadly elliptical, 9-11 micr.. minutely echinulate, white. MILK 

 white, unchanging, mild. Edible. 



Gregarious or scattered. On the ground in frondose woods or 

 open places. Ann Arbor, Lansing, etc., throughout southern Michi- 

 gan. July-August. Sometimes common. 



This species has the color of L. volemus but has distant gills, a 

 short stem and is usually smaller in size. It was described as 

 L. distans by Peck and it is regrettable that this appropriate name 

 could not be retained, as the distant gills are its most striking 

 characteristic. However, specimens of Curtis' collections are still 

 in existence and show the plant to have been described by Berkely, 

 as L. hygrophoroides. It is equally as good to eat as L. volemus.
