 (dd) Gills broad, rounded behind; spores 5.5-7 rnicr. 560. C. 

 malachius B. & C. 

 (aa) Pileus not white, 

 (b) Pileus riabelliform, narrowed to the base, ochraceous; gills con-

 i rocophyllus Berk. 

 (bb) Pileus dimidiate or subreniform, reddish-yellow, tomentose- 

 scaly; spores 6 micr. 564. C. dorsalis Pk. 



distans Pk. lias an eccentric stem: pileus small, 4-8 mm., 

 sulcate-striate, pubescent and tawny, spores elliptical, 10-12 x 

 6-7.5 micr.; the gills are very distant. C. latifolius Pk. came from 

 ohiu; pileus is sessile. 3-6 mm. broad, hygrophanous, white, almost 

 glabrous; gills very broad; spores globose, 5-6 micr. C. croceotinctus 

 Pk. has a pileus 1.5-2.5 cm. broad, glabrous, sessile, yellowish; 

 gills whitish becoming dull saffron-yellow; spores short elliptical, 

 5-6 micr. Long, i 



550. Crepidotus hserens Pk. 



X. V. State Mus. Rep. 35, 1881. 



PILEUS L-5 cm. broad, rarely broader, sessile, flattened-convex, 

 dimidiate, reniform, broadly cuneate, etc.. hygrophanous, viscid 

 from the thin but tough, gelatinous, separable cuticle, glabrous or 

 -lightly lioccose-squamulose, obscurely striatulate when moist, 

 watery-brown or tinged gray (moist) white or whitish (dry), white- 

 villose at the base, margin at first inrolled. FLESH thin. GILLS 

 close, narrow, radiating, whitish then brownish. SPORES broadly 

 ovate-elliptical, obtusely pointed at ends, smooth, 7-9x5-6 micr., 

 pale rusty-cinnamon in mass. 



On decaying woods of deciduous trees. In Washtenaw County it 

 was found in several localities, but not detected elsewhere. June- 

 September. Infrequent. 



This is our only truly viscid Crepidotus; C. mollis may become 

 slightly so in very wet weather. Our plants average larger than 

 those described by Peck, and the spores are slightly longer.
