25S THE AGARICACEAE OF MICHIGAN 



all of which are described with caps colored some shade of yellow. 



Our plant is edible, and is eaten by many with safety and relish. 

 In Europe, the same species is said to be poisonous, and is so 

 marked by Ricken in the latest, extensive work of that country. 



** Pileus viscid. 



246. Hypholoma peckianum sp. no v. 



PILEUS 1-2 cm. broad, convex, obtuse, subexpanded, viscid, 

 glabrous, bay-broun, blackish on disk, paler on margin, even, margin 

 bordered by white, silky fibrils from the veil. FLESH whitish, 

 moderately thin, thicker on disk. GILLS adnate, rounded behind, 

 2-3 mm. broad, abruptly narrower in front, close, at first flesh- 

 colored then dark purplish-brown, edge white- fimbriate. STEM 3-4 

 cm. long, 2-2.5 mm. thick, equal, white -floccose above, innately fibril- 

 lose elsewhere, pallid to brownish, brown within except the white 

 pith, at length hollow, flexuous. SPORES 10-12 x 5-6 micr., ventri- 

 c-ose-elliptical, pointed at ends, smooth, tinged purple under the 

 microscope, purplish-brown in mass. CYSTIDIA none. STERILE 

 CELLS on edge of gills, clustered, linear-cylindrical, obtuse, about 

 20 x 4 micr. BASIDIA subcylindrical, 30 x (\ micr., 4-spored. 

 ODOR and TASTE none. 



Scattered on debris of leaves and decayed wood in woods of hem- 

 lock, beech, maple, etc. New Richmond. September. Rare. 



The viscid, dark-colored cap, the flesh-colored young gills and 

 the small size, distinguish the species. The cortina is white and 

 distinctly fibrillose. 



Section II. Limbata. Pileus somewhat fleshy or thin, at first 

 innately fibrillose or dotted with superficial floccose scales on the 

 surface or margin. 



This group approaches the genus Psilocybe, but the veil is 

 always recognizable under favorable weather conditions by the 

 scries of floccose remnants which border the margin of the fresh 

 pileus ; in wind and rain these rapidly disappear. In most of the 

 species the remnants of the veil are scattered over the surface of the _ 

 very young pileus as superficial flocculent particles or minute scales ; 

 these usually disappear early. In other species the veil remains 

 hanging to the margin of the pileus in an appendiculate manner.
