746 THE AGARICACEAE OF MICHIGAN 



Adrian ate ('. morbifera with a mess of L. naucina. The victims 

 suffered blindness, swollen throat, etc. Our specimens did not 

 have the marked taste described by Peck, nor a truly "hollow" stem. 

 It is doubtless the same species however.

 umbilicate, hygrophanous, thin, glabrous, pale watery-brown and 

 even when moist, whitish or tinged tan when dry, edge of margin

 of traina differentiated and composed of delicate, long, subgelatin- 

 ous cells. GILLS subdecurrent, close, rather narrow, pale tvatery-
