CLASSIFICATION OP AGARK 



.Mostly separable from M. alcalina i>,\ it> terrestrial, scattered 

 habit, smaller si/.r and dry Btem. i/. metata has narrower spores, 

 the odor is fainl or obsolete, and the Bhape of the pileua is often 

 more convex. The stem of this Bpeciee i- slightly tough .1 ml mi^li t 

 on this account be referred to the Filipedes. The trama of the gills 

 is composed of rather large cells, among which globose vehicular 

 cells are conspicuous.

The microscopic characters are the besl mark of this Bpecies. The 

 color is between grayish-brown ami ashj (see Chapman), fading 



to pale ashy or whitish. The sha| f the cap varies considerably 



in the same patch. Fries, in his later work-. Epicrisis ami Bymen.

 campanulate, one-half inch across. Massee (British Fungus 

 Flora) ami Stevenson (British Fungi), mislead b} speak
