I' ILEUS 5-10 cm. broad, firm, convex then plane to subdepressed, 

 dry, at first covered with a delicate silky tomentum, glabrescent, 

 grayish-brown, dull, becoming isabelline, margin even. FLESH 

 white. GILLS decurrent, varying to merely adnate with a tooth, 

 ill in. close, pale gray at first, then rosy to salmon color, rather nar- 

 row. STEM 3-9 cm. long, 0-12 mm. thick, solid, fibrous, subequal, 

 minutely flocculose, sometimes striate, pale grayish-brown to isabel- 

 line. SPOKES elongated angular, irregular, 8-10 x 5-6 micr., 

 nucleate, pale rose color or almost salmon color in mass. CYSTIDIA 

 none. ODOR and TASTE somewhat farinaceous. 



(Dried: Pileus brownish-gray, stem sordid white, gills dingy deep 

 flesh colon. 



Subcaespitose, gregarious, occasionally solitary. Habitat varies: 

 found frequently in low woods of elm, maple, etc., on wooded hill- 

 sides, ravines, of frondose or mixed woods; sometimes on rotten 

 wood. Late August to middle October. Common in southern Mich- 

 igan. 



Often some of the individuals of one patch are attacked — ap- 

 parently by some other fungus — and do not develop the cap and gills, 

 Inn remain as abortive, whitish masses, with the appearance of puff- 

 balls; the interior however retains its whitish color, and does not 

 become brown, olive or purple as in puff-balls. Their shape varies 

 from globular to depressed, often umbilicate above. Sometimes all 

 of the specimens are found in this condition, but careful searching 

 of i he locality usually brings to light normal individuals. Mcllvaiue 

 says the abortive ones are fair eating.
