Agaricaceae 



Psathyreiia. away to almost nothing, but they are of fine flavor, which they impart 

 to the cooking medium. 



GOMPHI'DIUS Fr. 



A wooden bolt or nail. 



Hymenophore decurrent. Gills distant, composed of a mucilaginous 

 membrane, which can be readily separated into two plates, continuous 

 at the edge which is acute and powdered with the blackish fusiform 

 spores. Veil viscoso-floccose. Fleshy, putrescent, pileus at length the 

 shape of an inverted cone. 



A small genus with great difference among the species. Intermediate 

 in habit between Cortinarius and Hygrophorus. 



Universal Veil glutinous, at first terminating on the stem in a floccose 

 ring soon disappearing. The Gills frequently admit of being detached 

 and stretched out into a continuous membrane. Fries. 



A genus possessing several well-marked characters. The very decur- 

 rent gills differ from all others in their soft mucilaginous consistency. 

 The spores are larger than usual in the Agaricaceae and have the elon- 

 gated spindle-shape found in Boleti. The stem and pileus are of the 

 same substance, and the pileus and veil are both glutinous when moist. 

 The spores have been described as greenish-gray becoming black, and 

 as dingy-olive, 



I have had opportunity to see but two species of this small genus 

 G. rhodoxanthus and G. viscidus. Of these the spores are decidedly 

 olivaceous. If the six other species recorded as found in the United 

 States are as creditable, they are well worth hunting for. G. Oregonen- 

 sis Pk, is reported as edible and as a valuable food species in Oregon.
