CLASSIFICATION OF AGARICS 



to umber (Sacc.) when moist, hygrophanous, fading to whitish, 

 glabrous, Bubstriate or even when <\\\. margin ai first straight. 

 FLESH watery brownish then whitish, membranous, not very 

 fragile. GILLS adnate, with a decurreni tooth, ascending-arcu 

 moderately broad, subventricose, close to subdistant, whiU bhen 

 tinged with gray. Edge obscurely fimbriate, scarcely vein 

 STEM ".l cm. long, l '■'> mm. thick, often rather thick, p< iiu<i,i whiU , 

 shining, glabrous, even, straight, equal, hollow, fragile, easily split 

 longitudinally. SPORES 7-9x I 1.5 micr., oarrowlj elliptical 

 pointed at one end, smooth, white. CYSTIDIA rather abundant, 

 subcylindrical, obtuse, 50-65x8-9 micr. on Bides and edge of u'ill<. 

 ODOB aone. 



Scattered-gregarious on the ground among pine needles, moss, 

 leaf mold, in woods <>r white pine, beech, etc. New Richmond.

These plants have been temporarily referred to I/, dissiliei 

 they differ in thai the pileus is no1 sulcate and the odor is lack- 

 ing. The smell of l/. dissiliens is said to he unpleasant. Our 

 plant has a subgelatinoufl feel to the cap and stem, inn there is 

 no pellicle. The base of stem is scarcely hairy except where the 

 mycelium masses among the decaying leaf mold from which it 

 sometimes grows. The pileus dries to a glistening white, as i 

 thai <»f .1/. stannea Ft. It has the stature of a Collybia, as shown 

 in Pries' figure of his species. It differs from '/. hemispherica Pk. 

 to which it appears to be related, in the much larger spores. The 

 stem becomes very fragile with age and breaks on picking.

 fuscous below, toughish, sometimes compressed, hollow, mycelioid- 

 hairy and somewhat rooting. SPORES broadly elliptical. 8
