Gills generally free (rarely somewhat adnate). Terrestrial fungi. 



A. Procerae Fr. (sensu aug.). Cuticle of young cap (when in bud) 

 naked, smooth, but often soon cracking. Ring distinct, free. Spores

 obtuse, broad (breadth > half the length). 



a. macrosporæ. Spores 12x7 or more. 



a. squamulosce. Cuticle of cap soon cracking into scales; stem 

 scaly or squamulose, base bulbous. 



1. Scales dark brown, large L. procera (1) 



2. Scales ochraceous or pale crust-brown, minute . . L. umbonata (2) 



b. lævigatæ. Cuticle entire (or only somewhat irregularly 

 cracking near the edge), whitish, Stem smooth, almost 

 without bulb L. excoriata (3) 



(3. metasporæ. Spores 11x6 or less.

b. lævigatæ. Cuticle remaining entire (white); stem almost 

 without bulb L. naucina (5) 



B. Clypeolariæ Fr. (sensu alt.). Surface of stem and young cap more 

 or less covered with a fibrinous or floccose universal veil (rarely 

 almost glabrous). Cuticle cracking or entire. Ring generally inferior 

 or fugacious. Spores either small or large, but then somewhat 

 pointed and narrow (breadth ^ half the length). 



a. fusisporæ. Spores large, ellipsoid or fusiform, 9 — 18 n long, 

 a. squamulosce. Surface of cap broken up into innate 

 squamules.
