THE AGARICACEAE OF MICHIGAN 



nexed, seceding, rentricose, crowded, at first dark fuligineous, then 

 purple fuligineous. STEM 5-8 cm. long, 4-6 mm. thick, fleshy-fibrous, 

 rigid, fragile, hollow, equal, becoming fuscous and clothed with 

 fuligineous abrils. SPORES extremely irregular, 9-12x6-7 micr., 

 (Ricken). Inodorous." 



In woods. East Lansing. Reported by Longyear. 



The description is taken from Fries' Hymenomycetes Europei 

 and Stevenson's British Fungi. Atkinson has described a form 

 with a dull heliotrope-purple pileus and stem, with spores 7-11 x 

 6-7 micr., irregularly oval, coarsely angular, nucleate and 5-7 angled. 

 Tli is species differs from E. cyaneum in the hollow stem, adnexed, 

 almosl free gills and larger spores. It is rare in Michigan. 



Section III. Nolanidei. Pileus thin, hygrophanous, somewhat 

 silky when dry, often wavy and irregular.

 elm, beech, etc., sometimes in grassy places near woods. Ann Arbor, 

 New Richmond. July to September. Infrequent.
