flaccid, at first plano-convex, but broadly and deeply timbili- 

 cate, at length entirely concave (not infundibuliform), 1-2 

 in. broad, sooty when moist, grey or boary tan when dry, 

 margin even. Flesh tough, pallid. Gills decurrent, arcuate, 

 closely crowded, 1-2 lines broad, dark smoky-grey. At first

 in 0. maura are white. (Fries.) 



Distinguished from C. ditopa by the absence of smell.
