PILEUS 2-6 cm. broad, at first obtusely conic-oval, then campa- 

 nulate-expanded and broadly umbonate, cortinate, at first woolly- 

 fibrillose from dense white fibrils, later subglabrescent, not rimose, 

 whitish becoming straw-yellow to dingy ochraceous in age. FLESH 

 compact, thick on disk, white. GILLS emarginate-adnexed or al- 

 most free, moderately broad, ventricose, close, at first pale grayish- 

 white then grayish-clay color. STEM 3-6 cm. long, 4-9 mm. thick, 

 equal above the subemarginate bulb, white, stuffed, often striate, 

 silky shining, at first fibrillose, flesh satiny-shining. SPORES sub- 

 reniform, smooth, relatively broad, 8-10x5-6 micr. CYSTIDIA 

 abundant on sides and edge of gills, ventricose-lanceolate to subcylin- 

 drical, apex crystallate, 60-75x15-20 micr. ODOR rather strong, 

 somewhal nauseous. 



Gregarious. On the ground, in low, rich, frondose woods. Ann 

 Arbor. August-September. Infrequent. 



Without an examination of the microscopic characters, this spe- 

 cies might easily be confused with /. lanatodisca. In the young 

 stage the white woolly-fibrillose cortina is continuous with the fibrils 

 on the margin of the cap. At maturity the pileus becomes glabrous, 

 especially on the disk, while in I. lanatodisca the disk is marked at 

 last by the white fibrils. It is probable that Hard's Fig. 218, p. 269, 

 Mushroom Hook, of I. suboclvracea var. burtii Pk. is referable to 

 ilii< species.
