CYATHUS STRIATUS (Fig. 137). This species is usually 

 found on sticks, sometimes in the ground, but then attached to buried 

 sticks. While Crucibulum vulgare has more of a "domestic" nature,

being found often around houses, on chips in the wood yard, on board 

 walks, etc. Cyathus striatus has more of a wild nature, and is gen- 

 erally found in the woods on brush heaps, etc. It can always be 

 known by the striations or lines on the inside of the cups as shown in 

 our figure. Cyathus striatus is the only species in the United States or 

 Europe that has these marks. 3 The color of the cups is dark brown 

 or black, and the European form is darker than the American.* The 

 peridioles of Cyathus striatus only fill the lower part of the cup below 

 the striations. They have a thin, whitish, surrounding tunica, but the 

 eggs would be called black. I think there can be no trouble in recog- 

 nizing Cyathus striatus from its striations. 



CYATHUS VERNICOSUS (Fig. 138). This is the only 

 species that is likely to be found growing in the unmanured ground. 

 Sometimes it is attached to buried sticks, but it rarely if ever grows

on wood as the other species usually do. Like Cyathus striatus, it is 

 rather of a wild nature, being usually found on bare ground in fields, 

 borders of woods and similar places. It is readily known by the 



"In warm countries there are several species of this character. 



The American plant is a distinct form called var. Schweinitzii and differs from the Eu- 

 ropean not only in lighter color but in the structure of the tunica.
